Committee Scope: This Committee shall have primary responsibility for documents on safeguarding against the fire and explosion hazards associated with the storage, handling, and dispensing of flammable and combustible liquids at automotive a n d m a r i n e service stations and with related activities such as lubrication, minor repairs, adjustments, and routine maintenance work.

This list represents the membership at the time the Committee was balloted on the text of this edition. Since that time, changes in the membership may have occurred. A key to classifications is found at the front of this book.

The Report of the Technical Committee on Automotive and Marine Service Stations is presented for adoption.

This Re~ort was prepared by the Technical Committee on Automouve and Marine Service Stations and proposes for adoption amendments to NFPA 30A-1996, Automotive and Marine Service Station Code. NFPA 30A-1996 is published in Volume 2 of the 1999 National Fire Codes and in separate pamphlet form.

This Report has been submitted to letter ballot of the Technical Committee on Automotive and Marine Service Stations, which consists of 27 voting members. The results of the balloting, after circulation of any negative votes, can be found in the report.

The document when adopted will be redesignated NFPA 30A, Code for Motor Fuel Dispensing Facifities and Repair Garages.

(Log #CP22) 30A- 1 - (Tide): Accept SUBMITTEI~ Technical Committee on Automotive and Marine Service Stations RECOMMENDATION: Change the title of NFPA 30A to read: "Code for Motor Fuel Dispensing Facilities and Repair Garages." SUBSTANTIATION: This change reflects the broadened scope of NFPA 30A. Where this code originally was intended to cover only traditional liquid fuel automotive and marine service stations, it now has responsibility for essentially all vehicle refueling, regardless of the fuel; minor motor vehicle repair facilities, such as quick-lube and quick tune-up operations; and major repair garages. COMMITTEE ACTION: Accept. NUMBER OF COMMITI'EE MEMBERS ELIGIBLE TO VOTE: 27 VOTE ON COMMITTEE ACTION:

AFFIRMATIVE: 24 NEGATIVE: 1 ABSTENTION: 1 NOT RETURNED: 1 Kohut

EXPLANATION OF NEGATIVE: HARTMANN: The proposed rifle, "Code for Motor Fuel

Dispensing Facilities and Repair Garages," is awkward, difficult to verbalize, and more convoluted than it need be.

• "Code for..." is not used in other NFPA codes. Rather, it is the final word of the title in almost every case.

* Using "Facilities" in the title implies it has to do with solely physical issues of construction while the scope includes operational requirements.

, "Service station" is widely understood to be those places where fuel is dispensed and "repair garages" is similarly clearly descriptive.

I recommend renaming the code simply the "Service Station and Repair Garage Code." EXPLANATION OF ABSTENTION:

MISEL: I feel unqualified to provide an opinion on proposals not related to LPG.

(Log #CP52) 30A- la - (Chapters 1-11 ): Accept SUBMITrER: Technical Committee on Automotive and Marine Service Stations RECOMMENDATION: Editorially revise and renumber Chapters 1 through 11 of the current edition of NFPA 30A as follows:

Chapter $ DeFinitions

For the purposes of this Code, the following terms have the definitions given in this Chapter.

Aboveground Storage Tank. A horizontal or vertical tank that is listed and intended for fixed installation, without backfill, above or below grade, and is used within the scope of its approval or listing.

Approved.* Acceptable to the authority having jurisdiction.

A-3 Approved. The National Fire Protection Association does not approve, inspect, or certify any installations, procedures, equipment, or materials; nor does it approve or evaluate testing laboratories. In determining the acceptability of installations,

rocedures, equipment, or materials, the authority having risdiction may base acceptance on compliance with .NFPA or

other appropriate standards. In the absence of such standards, said authority may require evidence of proper installation, procedure, or use. The authority having jurisdiction may also refer to the listings or labeling practices of an organization concerned with product evaluations that is in a position to determine compliance with appropriate standards for the current production of listed items.

33

N F P A 30A - - MAY 2000 R O P

Authority flaying Jurisdiction.* The organization, office, or individual responsible for approving equipment, an installation, or a procedure.

A-3 Authority Having Jurisdiction. The phrase "authority baying jurisdiction" is used in NFPA documents in a broad manner, since jurisdictions and approval agencies vary, as do their responsibilities. Where public safety is primary, the authority having jurisdiction may be a federal, state, local, or other regional department or individual such as a fire chief; fire marshal; chief of a fire prevention bureau, labor department, or health department; building official; electrical inspector; or others having statutory authority. For insurance purposes, an insurance inspection department, rating bureau, or other insurance company representative may be the authority having jurisdiction. In many circumstances, the property owner or his or her designated agent assumes the role of the authority having jurisdiction; at government installations, the commanding officer or departmental official may be the authority baying jurisdiction.

Basement. A story of a building or structure having one-half or more of its height below ground level and to which access for fire- fighting purposes is unduly restricted.

Bulk Plant or Terminal. That portion of a property where liquids are received by tank vessel, pipelines, tank car, or tank vehicle and are stored or blended in bulk for the purpose of distributing such liquids b.y tank vessel pipeline, tank ear, tank vehicle, portable tank, o r c o l l t a l n e r .

Closed Container. A container as herein defined, so sealed by means of a lid or other device that neither liquid nor vapor will escape from it at ordinary temperatures.

Combustible Liquid. z A combustible liquid shall be defined as any liquid that has a closed-cup flash point at or above 100°F (37.8°C), as determined by the test procedures and apparatus set forth in 1-7.4. Combustible liquids shall be classified as Class !I or Class III as follows:

(a) Class II Liquid. Any liquid that has a flasb point at or above 100°F (37.8°C) and below 140°F (60°C).

4-3.4.2 ~-)- There shall be no openings except those necessary for access to, inspection of, filling, emptying, and venting of the tank. All openings shall be located in the top of the tank.

4-3.4.3 ~-~ Each fire-resistant tank shall be suitably anchored to withstand uplifting by groundwater or flooding, including when the tank is empty.

4-~.4.4 ~-d-)- Each fire-resistant tank shall be resistant to damage from impact of a motor vehicle or shall be protected by suitable collision barriers.

4-3.4.5 ~ Vent pipes that are provided for normal tank venting shall terminate at least 12 ft (3.6 m) above ground level.

4-3.4.6 ~)- Paragraph 2-3.6.7 of NFPA 30, Flammable and Combustible Liquids Code, shall not be used to reduce the size of the emergency venL

A~3.4 ~ NFPA 30A requires a "fire-resistant tank" to survive a 2-hr fire test using the fire exposure environment described in UL 2085, Standard for Insulated Aboveground Tanks for Flammable and Combustible Liquids, or an equivalent fire test protocol. It should be noted that other similar fire test procedures are used, such as the International Fire Code Institute s Uniform Fire Code, Appendix II-F, Protected Aboveground Tanks for Motor Vehicle Fuel- Dispensing Stations Outside Buildings, and Southwest Research Institute's 93-01, Testing Requirements for Protected Aboveground Flammable Liquid Fuel Storage Tanks, both of which use the same fire exposure. It should also be'noted that the Uniform Fire Code uses the term "protected tank" to describe tanks that meet Appendix II-F or SWRI 93-01.

Because of these differences, tanks will commonly be listed to both sets of criteri3. Where this is not the case, a tank labeled as "protected", in accordance with Appendix II-F or SWRI 93-01, can be considered to meet the requirements of 4-3.4.1. However, the opposite might not be the case. In other words, a "fire-resistmat tank", as defined in 4-3.4.1, might not meet all the criteria for a "protected tank", as defined by the Uniform Fire Code.

COMMENT ON AFFIRMATIVE: N O S A L : Miscellaneous editorial corrections/comments: • 2-2.2.1: UL 2085 needs to be italicized. • Combustible lic~uid definition. Insert "of NFPA 30, Flammable

and Combustible Liquids Code," following 1-7.4. • Appendix B is not incorporated in rewrite. • 4-2.()1 a and ().b • Delete "that do not exceed 60 gal.~ from

sentence, containers by definition cannot be more than 60 gal. • 4-~.3: Delete second sentence "Aboveground tanks so installed

shall be deemed as meeting the requirements of Chapters 2 and 3 of NFPA 30." Sentence is either redundant given the wording of 4- 3.2 or is a substantive change requiring separate public comment.

• 7-6.2: Replace ~The heating room" with "Thfs room." SCHULTZ: I am concerned that the editorial incorporation of

requirements for aboveground tanks, as currently written, may create confusion. All added text relating to aboveground installations did not include the word "storage" which.is part of the defined term "aboveground storage tank" (AST). The defined term requires an AST to be listed, comparable to the ~fire-resistant tank"

and the "protected tank," but unl ike tile u n d e r g r o u n d and aboveground "storage tank (def ined te rm)" allowed in NFPA 30. I would suggest e i ther removing the word "storage" f rom existing text (as editorial), or add ing the word "storage" to the addit ional rewrite text.

The first sen tence of Rewrite 6-5.1 differs f rom text f ound in the cu r ren t edition.

Rewrite 9-5.4 requires a nozzle with a la tch-open device in the first sentence . The requ i rements of 6-6.3, however, allow a nozzle that is NOT equ ipped with a latch open device.

Note: T[/is is 4-3.9.1 in the editorial rewrite of NFPA 30A. SUBSTANTIATION: The previous text duplicated some of the requirements of 2-4.4, Vaults. The Technical Commit tee concludes that tanks located in a building present a degree of risk that is best handled by installation in an enclosure that meets the requirements of a vanlt, since the hazard and risk are essentially the same. This a m e n d m e n t still allows a tank inside a building, but then references file requirements for vaults for suitable installation requirements .

(Log #4) 30A- 13 - (2-4.1): Accept in Principle SUBMITTER: Rick Thornberry, ConV~ult RECOMMENDATION: Add a new Section 2-4.1 to read as follows and renumber the remaining sections accordingly.

2-4.1 Approval Required. The use of aboveground storage tanks at automotive service stations, fleet vehicle service stations, and marine service stations shall be permi t ted in accordance with this

section when the specific installation is approved by the anthodty having jurisdiction. SUBSTANTIATION: Presently, this section does not contain adequate charging language which indicates the in tended scope of the section, which is for aboveground storage tanks at service stations as indicated in the tide.

However, titles are not enforceable in a code. This proposed new Section 2-4.1 provides that charging language which correlates witll Section 2-1.1(g) as it refers to this section.

This proposed new section also clearly indicates that the specific installation proposing the use of aboveground tanks must be approved by the an tho r i~ having jurisdiction. This allows the authority havingjur isdicnon to de termine the suitability of the proposed aboveground tank installation either as an unprotec ted aboveground steel tank, a fire resistant tank, or a tank in a vault based on the particular application and the relative hazard within the authorities having jurisdiction community. This will not allow a "blank check" for the installer of an aboveground tank to use any of the options in this section without first obtaining the specific approval of the authority having jurisdiction.

As Section 2-4 and Section 2-1.1(g) are presently written, any of the aboveground tank options specified in Section 2-4 could be used once the authority having jurisdiction has given his approval to allow the use of aboveground storage tanks even though his intent may have been to limit the use of aboveground storage tanks to a certain option within Section 2-4. This proposed new section will give him that specific authority. If this code intends to give the anthority having jurisdiction the authority to de termine when aboveground tanks are permit ted, that authority should be clearly stated to allow him to de te rmine the appropria te opt ion allowed for aboveground storage tanks in his jurisdiction for a specific applicat ion. COMMITTEE ACTION: Accept in Principle.

Add a new subsection 2-4.1 (new 4-3.2.1 in editorial rewrite of NFPA 30A) to read:

2-4.1 Approval Required. The use of aboveground storage tanks at automotive service stations, fleet vehicle service stations, and marine service stations shall be permi t ted when installed in accordance with the requirements of this section and with all applicable requirements of NFPA 30, Flammable and Combustible Liquids Code, and when the specific installation has been approved by the autl~ority having jurisdiction.

(Log #5) 30A- 14- (2-4.1.2): Reject SUBMITTER: Rick Thornberry, ConVault RECOMMENDATION: Add a new Section 2-4.1.2 to read as follows:

2-4.1.2 Aboveground storage tanks containing Class I liquids shall be installed in vaults in accordance with 2-4.4 or shall comply with the requirements for fire resistant tanks in 2-4.5. SUBSTANTIATION: In terms of their ignition potential, Class I liquids pose a more severe hazard than Class II liquids used as fuels for motor vehicles. This difference in hazard should be recognized by providing a greater degree of protection for tile storage of Class I liquids as compared to the storage of Class II liquids. Presently, this code does not differentiate between the two types of liquids for file purpose of applying the appropriate requirements for the use of aboveground storage tanks containing these liquids. However, the Commit tee accepted in part Proposal 30A-20 (Log #47) which allows the storage of Class II and Class IIIA liquids to be increased in capacity from 12,000 gallons individual tank capacity to 20,000 gallons and from 40,000 gallon aggregate capacity to 80,000 gallons at fleet vehicle service stations.

If file Committee can differentiate the hazard between Class I and Class II liquids based on its action taken on Proposal 30A-20, then, in effect, it is suggesting that Class i liquids do pose a greater fire hazard and should be treated accordingly. This public commen t will accomplish that hazard recognit ion by not permit t ing the storage of Class I liquids in unpro tec ted aboveground steel tanks

which are presently permitted based on the required separation distances greater dian those allowed for tanks in vaults or fire resistant tanks in accordance with Section 2-4.2.2.

It is unrealistic to expect that increased separation distances will provide adequate fire safety for up to 40,000 gallons of Class I liquids stored in unprotected aboveground steel storage tanks. Although the separation distances in Section 2-4.2.2 may be adequate for property protection and die prevention of exposure fires and exposure to the public, they do not solve the problem of fire fighter safety. When an aboveground tank becomes involved in a fire, the local fire department will attempt to extinguish that fire. Thus, the fire department is at risk and is exposed to the unprotected steel tanks involved in the fire. Should the emergency vent not operate properly or it be locked down for security reasons, there is a high probability that die tank may explode and endanger die lives of the fire fighters. This situation would be greatly minimized by die use of tanks installed in vaults or fire resistant tanks for the storage of Class I liquids as proposed by this public comment. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The Technical Committee feels that this proposal is unduly restrictive. Section 2-4 allows the use of steel tanks where there is adequate separation to ensure protection of adjacent property from a fire involving file storage tank.

(Log #6) 30A- 15 - (2-4.2.1): Accept SUBMITTER: Rick Thornberry, ConVault RECOMMENDATION: Revise Section 2-4.2.1 (4-3.2.2 in editorial rewrite of NFPA 30A) to read as follows:

2-4.2.1 Tanks storing Class I and Class II liquids at an individual site shall be limited to a maximum individual capacity of 12,000 gallons (45,600 L) and aggregate capacity of 40~0~ 48.000 gallons

SUBSTANTIATION: This public comment is intended to resubmit Proposal 30A-19 on the basis that die Committee Statement was in error. The Committee rejected the original proposal on the basis diat the 42,000 gallons aggregate capacity limit was deliberately chosen so that die facility would not trigger implementation of the U.S. Environmental Protection Agency's Spill Prevention Control and Countermeasures (EPA SPCC) rules for under~ound tanks. Interestingly enough, dais section only applies to aboveground storage tanks. However, die U.S. EPA SPCC rules also apply to aboveground tank installations having an aggregate capacity greater than 1,320 gallons or a single tank capacity greater than 660 gallons in accordance with 40 CFR Part 112. Thus, the SPCC rules could potentially be triggered by the types of installations regulated by this section. Furthermore, the Committee has accepted in part Proposal 30A-20 (Log #47) which allows die aggregate capacity at fleet vehicle service stations to be increased to 80,000 gallons when storing Class II and Class IlIA liquids only.

The original substantiation for Proposal 30A-19 was more related to practicality and economics of fuel deliveries without a significant increase in the relative fire hazard posed by die 20 percent aggregate capacity increase from 40,000 to 48,000 gallons. This recognizes the individual maximum capacity of 12,000 gallons per tank and would allow for die installation of 4 such tanks. Since most tank vehicles have a capacity between 8,500 and 10,000 gallons, a full tanker load can be received bya 12,000 gallon tank which has not yet been fully emptied prior to die delivery of the fuel. The present code would allow four I0,000 gallon tanks or three 12,000 gallon tanks and a 4,000 gallon tank to meet the 40,000 gallon aggregate capacity presendy specified. For these applications it would not appear that there would be any additional significant hazard posed by allowing the calPacity of die 4 tanks to be increased to the 12,000 maximum indiwdual capacity allowed if die aggregate capacity is increased to 48,000 gallons. COMMITTEE ACTION: Accept.

COMMITTEE STATEMENT: While the Technical Committee agrees with this proposal, it wishes to point out that it does so not for die reasons given by the submitter. The Technical Committee feels that the additional tank capacity will ensure that there is always adequate ullage to accommodate thermal expansion of the fuel and to prevent overfills when a full fuel delivery is added to a not-quite-empty tank.

(Log #7) 30A- 16- (2-4.2.1): Reject SUBMITTER: Rick Thornberry, ConVault RECOMMENDATION: Reject file proposal and delete the proposed new second sentence as revised by tile Committee which reads as follows:

"Tanks storing Class II and Class IIIA liquids at a fleet vehicle service station shall be limited to a maximum individual fueling capacity of 20,000 gallons (76,000 L) and an aggregate capacity of 80,000 gallons (304,000 L)." SUBSTANTIATION: Inadequate technical justification was provided to allow the capacities of individual tanks to be increased from 12,000 gallons to 20,000 gallons and the aggregate capacity of all tanks to be increased from 40,000 gallons to 80,000 gallons at fleet vehicle service stations. The definition for "fleet vehicle service station" as proposed in Proposal 30A-9 (Log #CP1) applies to virtually every fueling application which is done without servicing the public and would include such fleet operations as city and county governmental agencies, repair service fleets, and public utility fleets, as well as freight transport fleets which this proposal was originally intencled to address. This definition is much too broad in scope and would virtually allow these larger capacities at a vast number of installations at which unprotected steel tanks could be installed, provided the separation distances specified in Section 2-4.2.2 are met, which was certainly not envisioned when this section was originally incorporated into NFPA 30-1993.

The reference to the increased setbacks required by NFPA 30 for tanks based on tank capacity is not very relevant since the only increase in separation distances that would be required by Table 2- 6 of NFPA 30 is a 5 foot increase from 15 feet to 20 feet for the minimum separation distance from property lines and the opposite side of a public way. The separation distance of 5 feet from the nearest side of any public way or from the nearest important building on the same property would not change even though the tank capacity would increase from a maximum 12,000 gallons to 20,000 gallons. These separation distances are irrelevant when considering the separation distances specified in Section 2-4.2.2 which have not been proposed for increase due to the increased capacities proposed in Proposal 30A-20. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: This proposal was held over from the Report on Comments for the 1996 edition of NFPA 30A with the understanding fllat additional information would be provided by the submitter. The additional information has not been received.

As for technical justification for rejecting the proposal; the fuel storage systems that are allowed by subsection 2-4.2.1 are very unlikely to be situated at a small user's facility. In addition, the action on Proposal 30A-13 (Log #4) ensures that the authority having jurisdiction has the final say in whether such a system can be installed.

Balance of text to remain unchanged. SUBSTANTIATION: The quantity limit for tanks in vaults has been proposed for revision from 12,000 gallons to 15,000 gallons. Tank vaults are currently manufactured to accommodate tanks with up to a 15,000-gallon capacity, and many of these size vaults have been installed successfully. The existing 12,000-gallon limit was based on the philosophy that each tank should be allowed to be large enough to off-load an over-the-road tanker, i.e. 12,000 gallons. More recent practices involve blending of high-octane and low-octane products at the dispenser to generate a mid-grade product, as opposed to stocking mid-grade product in a separate tank. This process slightly increases the demand on the low-octane product, and it is considered preferable to have a slightly larger tank to accommodate this demand as opposed to having to install an additional tank.

(Log #CP15) 30A- 20 - (2-4.2.2 Exception No. 3 (New)): Accept SUBM1TTER: Technical Committee on Automotive and Marine Service Stations RECOMMENDATION: Add a new Exception No. ~ to Subsection 2-4.2.2 (4-3.2.3 of editorial rewrite of NFPA 30A) to read as follows:

Exception No. 3: At commerdal, industrial, government, and manufacturing establishments, where the tanks are intended for fueling vehicles used in connection with their business or operation, no minimum distance shall be required by 2-4.2.2(b) if the tank meets the requirements of Subsection 2-4.1 and also meets one of the following:

(a) The capacity of the tank does not exceed 1,100 rials; or (b) The tank is located at least 250 ft from any property line that

is or can be built upon, the nearest important building on the same property, and the nearest side of a public way."

(c) Delete 9-3.5 of 1996 edition. SUBSTANTIATION: Currently, Subsection 9-3.5 allows "private" fueling operations with up to a 6,000-gal tank and with no restriction on dispenser placement. However, as of the 1996 edition of NFPA 30A, this has been limited to pre-existing installations, with new installations having to meet the requirements of Chapter 2. There has been much debate on whether a dispenser can be mounted directly to the top of or immediately adjacent to a UL 142 tank and still result in a safe installation. This amendment essentially draws an equivalency between the installation covered by this exception and Exceptaon No. 2 for fire resistant and protected tanks. The Technical Committee feels that the two situations are equivalent. COMMITTEE ACTION: Accept. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 27 VOTE ON COMMITTEE ACTION:

"2-4.4 Vaults. Vaults shall be listed in accordance with UL 9245. Vaults shall be permitted... ' .

Balance of text to remain unchanged. SUBSTANTIATION: Underwriter s Laboratories has developed criteria for evaluating and listing tank vaults. The new criteria, set forth in UL 2245, require a high level of quality, and it is appropriate to require vaults that can pass this level of scrutiny. Because vaults provide crifcal protection for the tanks that they enclose, it is essential that they be designed and constructed in a manner that ensures reliable long-term performance.

Note that UL's required structural evaluation includes consideration of soil conditions; hydrostatic loading inside and outside and resulting buoyancy effects; vehicle loading on top of a vault; and seismic forces. In addition, UL 2245 requires that strength tests be conducted at the factory for each vault pour to verify the quality of concrete used. COMMITTEE ACTION: Accept in Principle.

I Revise 2-4.4 of NFPA 30A (4-3.3 of the editorial rewrite of NFPA 30A) by adding the following sentence:

In addition, adequate space must be available to perform maintenance on the tank, such as repair o f coatings, supports, etc., if the visual inspection de termines that such maintenance is needed. Tbe proposed revision clarifies these points.

In addition, the proposal clarifies that dispensing devices are allowed to be installed on tops of vaults, recognizing that the level of protect ion provided by a vault is equivalent to daat provided by a fire-resistant tank.

(d) Clarifies that only aboveground tanks can be used in vaults due to the lack of backfill. It would be inappropriate to install any o ther type of tank in a vanl~

(f)-(g) The first p roposed revision to (f) will allow vaults containing Class I liquids to be ventilated using either a continuous ventilation system or a ventilation system activated by a detect ion system capable of detect ing both liquid and vapor in the vault. The proposed requirements are consistent with provisions currently included in the UFC.

The second proposed revision to (f) deletes provisions now accommodated in a combined item dealing with vapor- and liquid- detect ion systems, (g). The dele ted text in the old (g) has also been accommodated by the newly proposed text. The proposed provisions for (g) are preferred because they more clearly detail needed requirements .

(n) The proposed revision to (n) will ensure that tanks in vaults are provided with a means to prevent an overfill condition. This adds an additional measure of safety to prevent the most likely source of spillage in a vault. COMMITTEE ACTION: Accept in Principle in Part.

(Log #9) 30A- 24- (2-4.5(a)): Reject SUBMITTER: Rick Thornberry, ConVault RECOMMENDATION: Revise Section 2-4.5(a) as follows:

2-4.5(a) The construction that provides the required fire resistive protection shall prevent ignition of the liquid iBslde the tank. release of liquid, failure of the primary tank, failure of the support ing structure, and impzarment of venting for a period of not less than 2 hours when tested using the fire exposure environment described in UL 2085, Oud~.c ~.f I~.vcz~ga:5~.~ S m n d ~ d for Insulated Aboveground Tanks for Flammable and Combustible Liquids, or an aonroved equivalent test procedure. SUBSTANTIA'I:I()N: Tiffs public comment to fur ther revise Section 2-4.5(a) is in response to the Commit tee Statement for rejecting the original proposal. The in tent of the revision is to indicate that ignition of the liquid that is stored inside the tank shall be prevented and not the ignition of any vapors that may be vented through the emergency vent which may occur after a significant fire duration. In the Analysis of Revisions to the 1994 Uniform Codes published by the International Conference of Building Officials, the following s ta tement is made regarding the primary tank temperature pass/fail criteria for the Uniform Fire Code Appendix Standard A-II-F-I:

"Pass/fail temperatures are based on the product most commonly stored, gasoline. As the primary const i tuent of gasoline, heptane is the reference material. The ignition temperature of heptane is listed in NFPA 325M as 399°F (204°C); thus, the maximum tempera ture of any single thermocouple is established at 400°F

54

N F P A 30A - - MAY 2000 R O P

(204~C). The average limit is established as 20 percent under the maximum temperature with a typical starting temperature of 60°F (16°C). Thus, 20 percent of 400°F is 320°F (240°C is 160°C), and 320°F (160°C) minus 60°F (16°C) the average starting temperature) equals 260°F (127°C)." I t is clear that the performance intended is to prevent the ignition

of the liquid that would be typically stored inside such tanks. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The intent of the requirements for fire resistant tanks is not directed at the subject of file submitter's proposal and substantiation. In view of the action on Proposals $0A-28 (Log #8) and 30A-13 (Log #4), the Technical Committee intends to retain the criteria for a fire resistant tank, as it allows more flexibility.

(Log #10) 30A- 25 - (2-4.5(a)): Reject SUBMITTER: Rick Thornberry, ConVault RECOMMENDATION: Revise as follows:

(a) The construction that provides the required fire resistive protection shall prevent release of liquid, failure of the primary tank, failure of the supporting structure, and impairment of venting for a period of not less than 2hours when t e s t e d u f n g a fire

in accordance with UL 2085, Standard for Insulated Aboveground Tanks for Flammable and Combustible Liquids, or equivalent testprocedure. SUBSTANTIATION: Since UL 2085 is now a full UL standard and many tank manufacturers have tested and labeled their fire resistant tanks in accordance with that standard, it would appear reasonable to direcdy reference UL 2085, rather than only referring to the fire exposure in UL 2085. Presently, as proposed by the Committee, Section 2-4.5(a) is, in effect, an ad hoc fire test method for fire resistant tanks to show compliance with this section of NFPA 30A. The UL 2085 standard contains the necessary high intensity pool fire exposure as well as performance and acceptance criteria for such tanks to assure that they comply with NFPA $0A. In fact, UL 2085 was developed for that purpose and was subsequently expanded to include performance evaluation of protected aboveground tanks to show compliance with the Uniform Fire Code Appendix II-F as well.

In NFPA codes and standards it is always preferable to reference available standards that provide the performance desired rather than to write ad hoc test methods and standards into the NFPA code or standard. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The language being proposed here would actually require all of dxe criteria of UL 2085 to be met by a fire resistant tank, including those for what UL 2085 calls a protected tank. This would prevent the user or installer from using other equally suitable methods for providing protection.

24.5* Fire-Resistant Tanks. Fire-resistant tanks shall be listed for the use intended and shall comply with all of the following:

(a) The construction that provides the required fire-resistive protection shall prevent release of liquid, failure of the primary

tank, failure of the supporting structure, and impairment of venting for a period of not less than 2 hr when tested using a fire exposure that s~mulates a high-intensity pool fire, such as that described in UL -20g~ 1709.

SUBSTANTIATION: Reference to UL 2085 has cause confusion in file industry due to UL changing this criteria several times. The fire exposure described in UL 2085 is taken from UL 1709 which has remained constant and is used and understood by all testing laboratories and fire engineers. This criteria does not require internal temperature readings. Existing industry temperature limits are not based on scientific tesdng or explosion resistance. Adequate venting is file most practical way of preventing internal combustion.

The UL 2085 Protected Tank Test Procedure does not require testing an actual tank. As can be noted from the UL 2085, 1997 edition test, the test sample is not representative of an actual tank or its performance in a fire.

In reality, heat is conducted into a tank through the tank penetrations, Locating thermocouples 12 in. from any penetration ~s designed to pass test criteria but not measure the hottest point in a tank.

Explosions (Autoignition), occur at the hottest point in a tank which is at the penetration unless there is an alternative source of heat as in a malfunctioning submergible pump or a tank heater.

Allowing maximum temperature rise of 400°F twelve inches from any penetration exceeds the autoignition temperature of Jet Fuel, especially within a low density atmosphere. (If the ambient temperature at the start of the test is 70°F, and the temperature rise is 400°F, you have surpassed the autoignition temperature of Jet Fuel - see ASME D1655-89.)

To my knowledge, UL has done no testing to verify that 400+°F is a temperature at which autoignition will not occur.

Use of an arbitrary temperature without linking it to a specific chemical is unscientific.

Note: Supporting material is available for review at NFPA Headquarters. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The text as currently written does not require compliance with UL 2085, only use of the fire test, which accurately reflects file intent of the Technical Committee.

2-4.5* Fire Resistant Tanks. Fire resistant tanks shall be for the use in tended and shall comply with all o f the

following: (rest of 2-4.5 to remain the same) Add an Appendix to 2-4.5 to read: A-2-4.5 NFPA 30A requires a "fire resistant tank" to survive a two-

hour fire test using file fire exposure envi ronment described in UL 2085, Standard for Insulated Aboveground Tanks for Flammable and Combustible Liquids, or an equivalent fire test protocol. It should be no ted that o ther similar fire test procedures are used, such as the Uniform Fire Code's Appendix Standard A-II-F-1, Testing Requirements for Protected Motor Vehicle Fuel Storage Tanks, and Southwest Research Instimte's 93-01, Testing Requirements for Protected Aboveground Flammable Liquid/Fuel Storage Tanks, both of which use the same fire exposure. It should also be noted that UL 2085 contains criteria for both " f r e resistant tanks" and "nrotected tanks." The Uniform Fire Code uses the term "protected tank" to describe tanks that mee t Appendix I I - F , ~ SWRI 93-01.or the nrotected tank" criteria in UL 2085.

Because of these differences, tanks will commonly be listed to both sets of criteria. Where this is no t the case, a tank labeled as "protected", in accordance with Uniform Fire Code Appendix Standard A-II-F-1. oF SWRI 93-01, or UL 2085 can be considered to meet the requirements of 2-4.5(a) for "fire resistant tanks". However, tile opposite might no t be file case.

(Log #11) ?,0A- 31 - (2-4.5(g) (New)): Accept in Principle SUBMITTER: Rick Thornberry, ConVault RECOMMENDATION: Add a new Section 2-4.5(g) to read as follows:

2-4.5(g) Tanks having a top tip with with a liquid-tight connect ion for a fuel-delivery hose or nozzle shall be provided with a noncombust ib le spill container at file fill connection, fixed to file tank, and equipped with a manual drain valve that drains into the primary tank. Tile spill container shall have a min imum capacity of 5 gallons (18.9 L). SUBSTANTIATION: This public comment slightly revises the original proposal by referring to a liquid-tight connect ion for the fuel-delivery hose or nozzle to fur ther clarify tile intent of tile

" proposal. The Commit tee Statement for rejecting file original proposal was based on an er roneous assumption that the fuel- delivery hose would be drained into file spill container in the open. Presently, Section 2-4.9.4 requires all tanks to be filled through a liquld-tight connection. That connect ion is required to have a check valve and shut off valve with a quick-connect coupling or a check valve with a dry-break coupling. This will generally prevent the fuel-delivery hose from causing an incidental spill when it is d isconnected from tile tank connect ion. However, a minor spill could occur, which dais spill container would be designed to collect and prevent from reaching file environment. For those filling operations where the large diameter hose is used and there is no nozzle connected to tile end of the hose, tile hose could be emptied into the tank directly through the liquid-tight connect ion and tile spill container would be des igned to collect any incidental liquid that may be released when that hose is disconnected from

56

N F P A 30A - - MAY 2000 R O P

that connection. There would be no need to drain the hose into the spill container.

As stated in the original proposal, the purpose of the spill container is to capture any incidental spills that may occur during the connection and disconnection of the fuel delivery hose or nozzle or any leaks that may occur during the fuel delivery process. This will prevent an accidental release of fuel onto the ground and provide additional fire safety at a very minimal cost. This requirement is almost identical to the provisions of Section 5.7 of Appendix II-F of the 1994 Uniform Fire Code. COMMITTEE ACTION: Accept in Principle.

I dd a new subsection 2-4.3.1 to read: "Tank fill connections shall be provided with a noncombustible

spill containment device." [Add as new second sentence to 4-3.2.4 of editorial rewrite of

2-4.7.1 Tanks that are not enclosed in vaults shall be enclosed with a chain link fence at least 6 ft (2 m) high. The fence shall be separated from the tanks hyat least 10 ft (3 m) and shall have a gate that is properly secured against unauthorized entry. Aboveground tanks shall be protected against vehicular collision by suitable barriers.

Exception N o . l : Tanks are not required to be enclosed within a fence if the prol~erty on which the tanks are located tdx-e~b]- has a perimeter security fence.

~cept io t l No. 2: When approved by the authority havin~ jurisdiction, fire resistant tanks located at commercial, industrial.

~overnmental. or manufacturin~ establishments where the tanks are intended for fuelin~ vehicles used in connection with their business shall not be reouired to be enclosed with a fence if the tanks are nrovided with Iockable fill onenin~s and the vents are secured to orevent tamoerin~ without imoairi-n~ their intended fimcfion. SUBSTANTIATI(3N: Presen(ly tanl~ in vaults are not required to be enclosed within a fence. This proposal allows fire resistant tanks to also be exempt from the fence enclosure under certain conditions but only if approved by the authority having jurisdiction. Fire resistant tanks are similar to tanks in vaults. The proposed new exception allows those tanks located at facilities generally not accessible to the public which are provided for fueling operatiom used in connection with their business to be located without a fence enclosure when the openings into the tank includinl{ the vents are secured against tampering without impairing their function. The purpose of the fence is to prevent unauthorized tampering with the tanks and their appurtenances. Fire resistant tanks are designed to be of substantial construction in order to provide the required fire resistive protection for the primary tank. ff the openings into the tank are properly secured to prevent tampering, then it appears reasonable to allow an exception for such tanks at locations that are generally not accessible to the public. COMMITTEE ACTION: Accept in Part.

I Delete the word "already" in the current Exception to current subsection 2-4.7.1 (4-~,.7 of editorial rewrite of NFPA $0.4,). Reject the proposed new Exception.

(Log #43) 30A- 36- (2-5.1): Reject SUBM!TTER: James H. StannardJr . , Stannard & Co. RECOMMENDATION: Add the following new requirement:

2-5.1 Propane cylinder exchange cabinets shall not be located upon, or immediately adjacent to, automotive fuel dispenser islands. SUBSTANTIATION: The Standards Council, in response to floor comments and ballot, revised the language of Paragraph 5-4.1 of the 1998 edition of NFPA 58 to increase the min imum distance between propane cylinder exchange cabinets and the doors or o ther entrances to buildings. As a part of that same decision, the Standards Council added a new requ i rement that requires those same cabinets to be located at least 20 feet f rom an automotive fuel dispenser.

As directed by the Standards Council, a meet ing of representatives of the 58 Technical Committee, the 101 Technical Committee, and a fire marshal was held to review the Council 's decision. A compromise was agreed to regarding the spacing of the cabinets and doorways and a Tentative Interim A m e n d m e n t was presen ted to the 58 Technical Committee. That T1A was approved by the Technical Commit tee and accepted by the Standards Council.

At the same time, a second TIA was proposed that would have eliminated the 20 foot requi rement between the exchange cabinets and automotive fuel dispensers. That TIA failed, by a very slim margin, to achieve the required plurality by the 58 Technical Committee. The Standards Council subsequently rejected the second TIA. However, the Council clearly indicated in its decision that NFPA 30A is the more appropriate documen t for this requirement .

The submit ter is o f the opinion that proposed language better addresses the concerns that have been expressed by the fire services than does an arbitrary distance requ i rement that might actually denigrate safety if precisely followed. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: If the issue of concern is exposure of a p ropane cylinder to a liquid fuel spill, then the distance to a dispensing device is no t relevant, but the distance to a point of transfer is significant.

58

N F P A 3 0 A - - M A Y 2 0 0 0 R O P

SUBSTANTIATION: Water tight conta inment manholes and sumps are. being installed as. p a art of an unde rg round p ip g . i n system m order to collect spills and leaks as a means o f c o m p h a n c e to EPA unde rg round storage tank system technical requirements . These devices are being used with fill pipe connections, piping systems manifold connect ions as well as submerged pumps and leak detect ion equ ipmen t with electrical requirements .

Many remote pumping systems have been installed because the distance f rom the storage tank to the dispensers exceeded the laws of physics. These remote components o f the system were often required to be buried below grade in a fabricated pit box with a loose fitted cover and al though this type of cover provided some means of ventilation, most pit boxes provided a fitting to accommodate a venting system to relieve the vapors. Note repor t f rom Nolan of Conta inment Technologies, "A sump riser is basically a tank itself that sits on top of the UST." This type of container should be vented.

Note: Support ing material is available for review at NFPA Headquar ters . COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The Technical Commit tee is not sure of the nature of the problem being addressed by this proposal. First, gasoline is not a Class IA liquid, it is Class IB. Second, gasoline vapors are denser than air and will no t move any appreciable distance up through the vent.

(Log #46) 30A- 41 - (3-8.2 (New)): Accept in Principle SUBMITTER: Sullivan D. Curran, Fiberglass Tank & Pipe Inst. RECOMMENDATION: Add Section 3-8.2 to read as follows:

"Below-grade U n d e r g r o u n d Dispenser Sumps. Piping componen t s constructed of low melt ing point materials shall be permi t ted to be used without backfill in below-grade, underg round dispenser sumps when third party tested using a fire exposure that simulates a high-intensity pool fire, such as that described in API Standard 607, Fire Test for Soft-Seated Quarter-turn Valves, or equivalent p r o c e d u re." SUBSTANTIATION: The widespread installation of secondary con ta inment sumps under motor fuel dispensers and self- conta ined pumps is no t compatible with the traditional me t hod of controll ing a sump fire, should it occur. Sump fires are rare, and when they occur, are self-contained and not a threat to proper ty and personnel . Safeguards such as pump shutdown, readily accessible fire extinguishers, and a t tendant training requirements are in place. Further, pump pressures seldom exceed 27 psi, and in the shutdown mode are less than 10 psi. An appropriate fire

exposure test protocol is embod ied in API Standard 607 and may be used as the benchmark for o ther testing organizations. COMMITTEE ACTION: Accept in Principle.

In the editorial rewrite of NFPA 30A, as modif ied by Proposal [ 30A-56 (Log #CP41), add a new i tem (d) to read: ] (d) in conta inment sumps, provided the piping components can

successfully pass the test p rocedures descr ibed in API Standard [ 607, Fire Test for Soft-Seated Quarter-Turn Valves.

COMMITTEE STATEMENT: T h e Technical Committees version integrates the proposal into o ther p roposed amendments . NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 27 VOTE ON COMMITTEE ACTION:

AFFIRMATIVE: 24 ABSTENTION: 2 NOT RETURNED: 1 Kohut

EXPLANATION OF ABSTENTION: MAGERA: The primary purpose of this proposal was to establish

a fire exposure test that would be weaker than the UL842 Test, but one that is still credible to third party certifiers and AJH's. The parameters of the test fire in API 607 are more than adequate, however, o ther test condit ions could p r e sen t potential safety and liability hazards when piping so tes ted is installed in dispenser sumps.

The test pressure of 30 psi is far below the pressures seen in typical installations and would represent a dangerously weak link in a pressure system where all o ther componen t s are rated no less than 50 psi and are subject to surge pressures well in excess of 200 psi. Note that third party certifiers establish a 50 psi rating based on over-pressure tests of 150 to 500 percent to establish reasonable safety factors. Based on these accepted safety factors, a test conducted at a maximum pressure of 30 psi results in an effective pressure r a t i n g o f only 6 to 20 psi.

In API 607, the primary basis for acceptance is Leakage Through The Valve (Which in Non-Existent in Piping) Not in Excess of 100 or 1000 ml Per Minute. The o ther basis for acceptance is External Leakage Not In Excess of 25 or 250 ml Per Minute At The Valve Stem And Joints (Which Don ' t Exist in Piping) And No Limits For End Connections. Submitters and Certifiers could have a p rob lem establishing clear criteria for passing or falling a product .

Past history indicates that once a partial test criteria is published there will always be at least one certifier who will consider that to be the only criteria and publish a listing documen t a round just the fire exposure test. This makes it difficult for more conscientious certifiers to publish safety standards that address the o ther hazards associated with low mel t point materials.

It is unfortunate that the API 607 documen t was nei ther proved prior to nor even at the meet ing during which these significant topics might have been discussed and resolved.

Exception: An existing fuel dispensing island (2) not meet ing the requirements above and having no physical protection shall be required to: (1) Rebuild the island(s) for compliance, or (2) Add physical protect ion to pro tec t fuel dispensing units from collision damage f rom all directions. SUBSTANTIATION: Current NFPA 30A does not provide a definition or required dimensions for a concrete island in reference to dispensing f lammable or combustible liquids. The absence of requi rements for island(s) creates problem(s) for enforcement of the Code. Islands have always existed for purposes of protect ing the pumps. However, no dimensions or design criteria has been provided by the Code.

As a result of the absence of criteria for fuel dispensing island(s) at service stations (public or private), a survey was conducted th roughout the State of West Virginia to de termine the current criteria for fuel dispensing islands. The criteria submit ted to the Commit tee is the result of Fire Marshals conduct ing on-site inspections of existing fuel dispensing islands. This criteria is what is most commonly identified. COMMITTEE ACTION: Reject. COMbffTTEE STATEMENT: Historically, NFPA 30A has not been

~bP lied retroactively, as is true of most NFPA codes and standards. e Technical Committee feels that the authority having

jurisdiction already has the option of retroactively enforcing the provisions of this code on a ease-by-case basis.

COMMITTEE STATEMENT: These issues are addressed by national weights and measures rules that govern marking and labeling of dispensing devices. So, additional markings would duplicate these, possibly resulting in confusion. The Technical Committee notes that the dispensing nozzles for gaseous fuels are unique to each fuel and cannot be physically mated to the "wrong" receptacle on the vehicle. Likewise, a diesel nozzle is too large (in diameter) to be inserted in the fuel fill tube of a gasoline-powered vehicle.

SUBSTANTIATION: On mixed occupancy sites, such as used for "big box" marketing areas and strip malls, the general public will invariably choose the most direct route of travel between the property's access point and the occupancy they seek. If a service station is a secondary occupancy on such a property and unrelated vehicle traffic is allowed to pass unhindered through the service station's dispensing area, there is a serious potential for collision with vehicles being fueled and with dispensing, devices, with subsequent ignition of spilled fuel. This reqmrement attempts to provide some control over the situation. COMMITTEE ACTION: Accept. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 27 VOTE ON COMMITTEE ACTION:

"Pumps shall be listed and the system shall be designed or equipped so that no part of the system will be subjected to pressures above the maximum rated working pressure of any component in its system." SUBSTANTIATION: Currently, these systems are custom designed with the major components supplied from various sources, without overall supervision, control or regulation. Originally these systems were supplied as a standard package, all major components included, by the dispenser manufacturer.

In order to design the most efficient size remote pump for a multi-remote dispensing system, control the systems pressure from each remote dispenser, this would be more compatible with the

(Log #23) 30A- 58 - (Table 7): Accept in Principle SUBMITrER: Mark R. Hilbert, State of New Hampshire RECOMMENDATION: To add an asterisk Note to Table 7. To

lace an asterisk symbol after the words "Underground Tank" in able 7. Note to read "For Tanks Aboveground" see Table 5-3.5.3

in NFPA 30. SUBSTANTIATION: With the ever growing popularity of aboveground tanks at municipal, state, and commercial fuel dispensing sites we find the need to define the classified areas in the vicinity of aboveground tanks. There is no language included in Table 7 covering this type of installation.

NFPA 70 Table 514-2 is extracted material from Table 7 in NFPA 30A. Table 514-2 classifies areas for fuel dispensing sites and includes language relative to underground tanks, but none for aboveground tanks. NFPA 70 Table 515-2 is extracted material from Table 5-3.5.3 in NFPA 30. Table 515-2 classifies areas of bulk storage plants and includes language relative to aboveground tanks. The problem is that Table 515-2 is for bulk storage plants, where the flammable liquids are received by tank vessel, pipelines, tank car or tank vehicle and are stored or blended in bulk for the purpose of distributing such liquids by tank vessel, pipeline, tank car, tank vehicle, portable tank or container, and cannot be applied to fuel dispensing sites.

I submitted a proposal to NFPA 70 to add an asterisk note to Table 514-2 to reference Table 515-2 for aboveground tanks. Code Making Panel 14 agreed the proposal had merit but rejected it because the material in the table is extracted material and cannot be changed. Code Making Panel 14 recommended this proposal be submitted to NFPA $0A.

Acceptance of this proposal would add the language for aboveground tanks to Table 7 in NFPA 30A and allow the language for aboveground tanks to be added to Table 514-2 in NFPA 70. COMMITrEE ACTION: Accept in Principle.

Incorporate into Table 7 (Table 8-3 of editorial rewrite of NFPA 30A) the electrical area classification information for aboveground tanks, as shown in Table 5-9.5.3 of NFPA 30, Flammable and Combustible Liquids Code.

• Listed components are tested to five times the normal operating pressure.

* A slow shut-off would increase the probability of a spill and its resultant volume.

• New Onboard Refueling Vapor Recovery (ORVR) systems require a liquid seal to ensure vapor capture in the vehicle's system and to prevent spitback. A slow shut-off would interfere with this system and lead to excessive vapor release to the environment.

(Log #22) 30A-83 - (9-4.8 (New) a n d A-9-4.8 (New)): Reject SUBMITTER: Matt Gnstafson, Severna Park, MD RECOMMENDATION: Add a new Section 9-4.8 and A-9-4.8 as follows:

9-4.8* Stations shall have available for immedia te use m e a n s for prevent ing vehicles f rom en te r ing the area o f a liquid fuel spill. Each station shall have a spill response kit. T he spill response kit shall contain ins t ruct ions for stat ion pe rsonne l a n d shall include a roll o f yellow barrier tape, m i n i m u m 2 inches wide. Station a t t endants shall be i n fo rmed of safe and effective m e t h o d s for prevent ing the public f rom en te r ing the area of a fuel spill.

A-9-4.8 This provision is i n t ended for spills having a hazard equal to or greater t han a one gallon spill o f gasoline. Means for prevent ing vehicles and the public f rom en te r ing a fuel spill a rea may include gates, chains, barricades, traffic cones, or plastic barrier tape. Plastic barrier tape may be the sole m e a n s for prevent ing vehicle ingress where suitable p e r m a n e n t s t ructures or fixtures exist to attach the barrier tape outside the likely areas of spill occurrence. Vehicles, such as au tomobi le s and tow trucks, pose a source of ignit ion and are no t suitable for use as barriers. A l though merchand i se , t rash cans and advert is ing material may be used as supp lemen ta ry devices to block vehicle traffic, they shou ld no t be coun ted towards m e e d n ~ the r equ i r emen t s of 9-4.8. Station a t t endan t s shou ld be familiar with the need to protec t the public f rom the fire hazards associated with spilled gasoline. At tendants shou ld have immedia te access to p rocedures and suppl ies for co rdon ing off a spill a rea and any sloped area where the spill is likely to run. Station a t t endan t s shou ld be familiar with personal safety measu res such as no t walking in or nea r the liquid spill a n d vapor area- At tendan t s shou ld also be familiar with p rocedures to prevent ignit ion sources f rom being in t roduced in the spill or vapor area. S U B S T A N T I A T I O N : A fuel spill can occur f rom a variety o f sources, including: malicious spill, overfill, d a m a g e d fuel dispenser , b roken hose , over tu rned portable tank, or delivery vehicle spill. It is impor tan t tha t vehicles a n d people be prevented f rom en te r ing the spill area. I witnessed a spill at an a t t ended self service station where the vehicle tha t c a u s e d t h e spill drove away. The a t t endan t shu t off the power to the p u m p but called his supervisor before calling the local fire depar tmen t . T h e spill occurred on a Saturday a f t e rnoon at a stat ion on a busy road. Dur ing the t ime between the occur rence of die spill and the arrival of the fire depa r tmen t , n u m e r o u s vehicles pul led up to the pump. In each case tile driver got out of the vehicle, walked througl l the middle of the spill to the pump , found the p u m p deenerg ized and subsequent ly left. As soon as one vehicle would drive off, a n o t h e r would see die island empty o f traffic and pull in. O n e elderly driver threw a cigarette on the g r o u n d as he got ou t o f his vehicle. The station a t tendant , who was abou t 16 years old, eventually moved some heavy trash cans to block off die area. If he had a roll of yellow barrier tape available and had been ins t ructed on its use, he could have quickly s topped die public f rom en te r ing the spill area. It is equally impor tan t for stat ion a t t endants to know no t to en te r die spill a rea and to stay out of vapors genera ted by die spill. This informat ion could easily be provided to the a t t endants in written form such as par t of an existing p rocedures manual .

Fur thermore , NFPA 10 provides a specific def ini t ion o f die te rm "travel distance," whereas no such defini t ion is provided in NFPA 303- C O M M I T r E E ACTION: Reject.

NFPA 1O prescribes m i n i m u m dis tances so tha t ex t inguishers are readily accessible to those who need them. NFPA 10 also assumes tha t these persons are t ra ined in the use of ext inguishers .

NFPA 30A's ph i losophy is n o t to have such ready access because the Technical Commi t t ee does no t want to pu t the service station pa t ron in the posit ion of having to f ight a gasol ine fire. In addit ion, NFPA 30A assumes tha t the pa t ron will n o t be t ra ined in us ing an ext inguisher .

68

N T P A 3 0 A ~ MAY 2000 R O P

Committee Sta tement for rejection. Fire extinguishers are provided near hazards for the purpose of extinguishing fires in their incipient stages - ei ther patrons or a t tendants can use them. NFPA 10 does not assume persons using fire extinguishers are trained. The travel distances required by NFPA 10 insure that an extinguisher can be deployed before a small fire becomes a large fire.

The Commit tee Sta tement that 3OA is an occupancy-specific code is incorrect. There is nothing in NFPA 3OA that addresses fire extinguishers for the occupancy hazards of automotive or marine service stations. These occupancy hazards are Class A in nature and are not ment ioned. Also, there is no definition for travel distance to the extinguishers for the occupancy hazards, and the one given for the Class B hazard is grossly deficient.

The requirements of NFPA I0 are ~ , and even those are not being met by NFPA 30A. Fire extinguishers are a first line of defense in a balanced fire protect ion plan and must be included per the recommendat ions of the NFPA 10 Committee, who has the expertise in the area of fire extinguishers.

HAUSZ: I disagree with the Committee 's alleged responsibility for the placement of extinguishers and it's decision to accept a s tandard below a min imum set by NFPA 10.

I believe the committee wrongfully assumes gas station at tendants have undergone Fire Extinguishment training. I fur ther believe the extinguisher should be readily available for use by anyone. EXPLANATION OF ABSTENTION:

"Piers that are required to have a Class HI standpipe installed in accordance with NFPA 14 shall be provided with one (1) portable (wheeled) foam fire fighting and vapor suppression apparatus of 30 gallon or greater capacity." SUBSTANTIATION: Because of the high risk of fire during the vessel fueling process it is essential to have fire and vapor suppression capability. By having a portable foam fire fighting apparatus which can be attached to the required standpipe system, fuel personnel will have a high volume, major knockdown fire figlmng capability while awaiting fire department response.

Under the current standard, only water and portable hand held extinguishers are required. As shown in numerous fire histories documented by NFPA and others, fire hoses and hand held extinguishers have been grossly ineffective when fighting fuel-based fires or suppressing fuel leak vapors.

Therefore, to provide a greater level of additional protection at marine service stations, it is recommended that NFPA 30A be changed to include the placement of portable 30 gallon or greater foam fire fighting and vapor suppression apparatus wherever Class III standpipe is required. Also, it could be recommended that such apparatus should be available at all types of marine service stations. Such equipment would utilize water pressure to proportion the foam concentrate in producing foam solution and would not require a foam concentrate pump.

Having a high volume, powerful foam fire fighting and vapor suppression first response capability is even more critical when local fire departments are outside of a five minute response time. Also, in many instances, the responding fire truck may not have any or very little foam aboard. As a fire lieutenant of a metropolitan fire department stated, "We usually have just enough 5 gallon cans of foam onboard to get ourselves into trouble." These circumstances dictate that marine service stations take greater steps to protect lives and assets through a higher level of first response, such as provided by portable 30 gallon or greater foam fire fighting and vapor suppression systems. COMMITTEE ACTION: Reject.

not allow any travel distance greater than 50 feet for any type of Class B fire extinguisher placement.

Furthermore, NFPA 10 provides a specific definition of the term "travel distance," whereas no such definition is provided in NFPA 30A. In the case of a marine service station the current NFPA 30A standard could be interpreted to allow travel distances over water.

This section of NPFA 30A also conflicts with Sections 4-3.1 and 4- 3.3 of NFPA 303, Fire Protection Standard for Marinas and Boatyards. NFPA 303 Section 4-3.1 requires NFPA 10 to be followed for the placement of fire portable fire extinguishers and Section 4-3.3 goes beyond the minimum requirements of NFPA 10 and requires a fire extinguisher be installed on two sides of any fuel-dispensing area.

SUBSTANTIATION: Underwriter's Laboratories has developed criteria for evaluating and listing tank vaults. The new criteria, set forth in UL 2245, require a high level o f quality, and it is appropriate to require vaults that can pass this level of scrutiny. Because vaults provide critical protection for the tanks that they enclose, it is essential that they be designed and constructed in a manner that ensures reliable long-term performance.

Note that UL's rec)uired structural evaluation includes consideration of sod conditions; hydrostatic loading inside and outside and resulting buoyancy effects; vehicle loading on top of a vault; and seismic forces. In addition, UL 2245 requires that strength tests be conducted at d~e factory for each vault pour to verify the quality of concrete used. COMMITTEE ACTION: Accept.

This is based on an orifice coefficient of 0.8 and an environmental factor o f 0.5. The 0.5 environmental factor recognizes the limited t ime that a small tank will be exposed to fire, loss of fuel by absorption into the soil, and drainage of liquid away f rom the tank.

EXPLANATION OF NEGATIVE: SHAPIRO: The proposed Chapter 13 is in tended to serve as

rep lacement for NFPA 395, which deals with dispensing of motor fuels at remote locations and provides a vadety of unique exceptions to NFPA 30A's requirements . However, the provisions of NFPA 395 have generally existed in obscurity, with the document

iCally going unnot iced until recently. Now, with incorporat ion A 395's provisions into NFPA 30A, these provisions will take

on high visibility, having been given a renewed sanction by the NFPA 30A Committee.

The technical basis for many of the NFPA 395 provisions appears questionable, and the need to maintain the provisions in the new

72

N F P A 30A - - MAY 2000 R O P

NFPA 30A is far f rom evident. When NFPA 395 was developed, NFPA 30A had no allowance for dispensing of motor fuel f rom bare steel tanks, and in that circumstance, there was some justification for having a separate d o c u m e n t to provide such an allowance. However, NFPA 30A as proposed permits a bare steel tank to be used for motor fuel dispensing on less than an acre of land. In addit ion, the d o c u m e n t proposes to allow no separation distance between fuel dispensers and tanks when adequate separation from exposures is provided.

Given these allowances in NFPA $0A without the addit ion of the new Chapter 13, there is no apparent need to provide the new chapter for farms and other remote locations, particularly considering that de te rmin ing sites that would qualify for application of Chapter 1S would be entirely subjective, without any significant guidance in the document . NFPA 30A's current approach of specifying special provisions based on specified distances is preferable, a n d leads to more uniform code enforcement .

ff there are specific provisions in NFPA 395 that are deemed necessary for remote areas, these provisions should be directly incorporated into relevant sections of NFPA 30A rather than having a separate chapter. EXPLANATION OF ABSTENTION:
