(Log #32) 33- 15 - (3-1): Accept in Principle SUBMITTER: Gera ldJ . Rosicky, IFPS RECOMMENDATION: For the four th pa ragraph of Section 3-1, revise the existing sen tence "A luminum shall no t be used." to the following:

"Aluminum shall no t be used for structural suonor t members , the boo th or r oom enclosure, and its associated ventilation ductwork. A l u m i n u m may be used for interior c o m o o n e n t s of the boo th such

platforms, spray appara tus comt)onents , and o ther ancillary

S U B S T A N T I A T I O N : A l u m i n u m has long been recognized as a metal that loses its tensile s t rength u n d e r h ighe r hea t condi t ions as compared to steel, as well as having a low mel t ing poin t [1220°F (660°C)]. I have provided two figures f rom the NFPA Fire Protect ion H a n d b o o k (18th edit ion) which details the tensile differences in these two materials at elevated temperatures . These are f rom pages 4-187 a n d 4-188 concern ing metals. At 700 degrees F, a l u m i n u m has a tensile s t reng th of only about 4500 psi, whereas steel at the same t empera tu re has tensile s t rength of 50,000 psi. As a result, if a l u m i n u m is used for the suppor t ing members , the booth or room enclosure or its ductwork, the re will be structural failure at relatively low elevated tempera tures . However, the use of a l u m i n u m in the inter ior would no t affect s tructural stability.

COMMITTEE STATEMENT: This issue has been addressed by Proposal 33-14 (Log #CP15). NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 28 VOTE ON COMMITTEE ACTION:


(Log #CP15) 33- 14- (3-1): Accept SUBMITTER: Technical Committee on Finishing Processes RECOMMENDATION: Replace the fourth paragraph of Section 3- 1 with the following text:

"Aluminum shall not be used for structural support members or the walls or ceiling of a spray booth or spray room enclosure. Aluminum shall also not be used for ventilation ductwork associated with a spray booth or spray room. Aluminum shall be permitted to be used for interior components, such as platforms, spray apparatus components, and other ancillary devices." SUBSTANTIATION: The Technical Committee recognizes that aluminum loses structural strength at relatively low temperatures and has a low melting point (1220°F or 660°C). At 700°F, aluminum has a tensile strength of only 4500 psi, whereas steel has a tensile strength of 50,000 psi at the same temperature. Thus, if aluminum is used for supporting members, the walls or ceiling, or the ductwork, there will be structural failure at relatively low temperatures should a fire occur. However, use of aluminum components inside the booth would not affect structural integrity of the booth or room. COMMITTEE ACTION: Accept.

(Log #17) 33- 30 - (%1.3 Exception No. 3 (New)): Reject SUBMITTER: Peter Hohnquist, ATR Industries, Inc. RECOMMENDATION: Add the following Exception:

Exception No. 3: In a totally enclosed spray booth with a fire extinguishing system and a directly connected air make-up system. SUBSTANTIATION: While the intent of not interlocking the Air Make-up and spray area exhaust system with the fire alarm/extingmshing system is to keep the fire moving into the containment area of an open front, open top, or open side (i.e., conveyer design) spray booth or spray area, this is not, in our estimation, appropriate for a fully enclosed spray booth.

A fully enclosed spray booth can provide containment in a fire condition especially when fire dampers are utilized in both the supply and exhaust ducts and the ventilation system (make-up air fan and exhaust air fan) is cut-out through an interlock, upon a fire alarm or fire condition. Furthermore, utilizing low leak open/close dampers on both the supply and exhaust side will further enhance the fire containment and the flow of air to the fire is virtually eliminated.

In addition, the interlock/shut down system eliminates another serious condition of extreme positive or negative air pressure within the enclosed booth structure, in the event that only half of the ventilation system is rendered inoperable due to the fire condition. Many spray booth designs would not be able to sustain the extreme pressurization and would either "explode" or "implode" from the extreme pressure, thereby opening up the fire condition to the surrounding area.

It is our firm belief that the safest approach when dealing with a fully enclosed spray booth is to utilize interlocks to shut down both thesupply and exhaust air fans, close both supply and exhaust

dampers, utilize fire dampers, and through this containment, render the fire condition too "lean" to burn and allow the extinguishing system to do its job. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: Spray booth fires generate an enormous amount of smoke very rapidly and this smoke will quickly move to surrounding areas if not exhausted. This would severely impair the ability of personnel to evacuate and of fire fighters to effect rescue and fire control.

ff enclosed, the possibility of backdraft exists. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 28 VOTE ON COMMITTEE ACTION:

2. Two mil polyethylene sandwich bags are widely avail'able and inexpensive.

3. Overspray on poly bags is more obvious than on paper. 4. Proposal is cost neutral.

(Log #6) 33- 39- (9-5.2): Accept in Principle SUBMITTER: Erling L. Horn, Binks Mfg. Company RECOMMENDATION: Revise 9-5.2 to read as follows:

9-5.2 Spray equipment installed after July 2, 1999, shall be listed. SUBSTANTIATION: We request this amendment for the following reasons. The published date of July 1, 1996 is less than 10 months away. Binks Manufacturing Company and Sanles Electrostatic, Inc. have had meetings and discussions with three (3) listing firms prior to the request for a TIA. We (Binks and Sames) find there is not a protocol published to test incentive equipment covered by our standard. Factory Mutual has a draft standard; however, this test protocol will not be ready for publication and public distribution in time to allow manufacturers to submit equipment for test and approval. Factory Mutual appears to be the sole testing source for listing incentive electrostatic equipment. Factory Mutual indicated to us that all prior listed equipment will have to be re-examined under the light of the new standard when the standard is published. It is not possible for all suppliers to be listed by July 1, 1996, since Factory Mutual may be the only testing source. Binks Manufacturing Company and Sames Electrostatic, Inc. find these circumstances have resulted in an adverse impact on our ability to market our equipment to existing and future customers. We believe that other electrostatic equipment manufacturers have similar concerns with respect to the listing date requirements. We believe Factory Mutual cannot accomplish all the work required to list all of Binks and Sames equipment and other equipment suppliers by July 1, 1996. COMMITTEE ACTION: Accept in Principle.

Replace the existing Section 9-5 with the following: "9-5 Listing and Approval of Equipment. Spray equipment shall

be listed. Exception: Spray equipment that was installed prior to December

31, 1997 shall be listed or approved." COMMITTEE STATEMENT: The action on this proposal incorporates Tentative Interim Amendment 95-1 made to the 1995 edition of NFPA 33. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 28 VOTE ON COMMITTEE ACTION:


(Log #24) 33- 40 - (9-5.2 Exception No. 2 (New)): Accept SUBMITTER: J .J . Mroczka, Ford Motor Co. RECOMMENDATION: Add Exception No. 2 to 9-5.2 to read as follows:

Exception No. 2: This requirement shall not apply to automatic electrostatic spray equipment where all of the following additional fire protection is provided:

(a) The flame detection system shall use optical flame detectors. In addition to the requirements in 7-6(b), the optical flame detection system shall also activate an open head deluge system designed to discharge a minimum density of 0.6 gpm/sq ft (24.4 mm/min) over each affected automated zone.

(b) Manual deluge activation stations shall be installed at each personnel entrance to an automated electrostatic spray zone. These devices shall activate the open head deluge system for die "affected antomated zone and accomplish the requirements in 7- 6(b).

(c) A wet pipe sprinkler system shall also be provided throughout the spray booth. This system shall meet all the applicable requirements of NFPA 13, Standard for the Installation of Sprinkler Systems, for Extra Hazard (Group 2) occupancies.

(d) The automated zone open head deluge systems and spray booth wet pipe sprinkler system shall be supplied by separate or dual fed water supply piping.

(e) Automatic electrostatic equipment enclosures containing paint delivery systems shall be protected with an approved automatic fire suppression system. Activation of this system shall automatically accomplish the requirements of 7-6(b). SUBSTANTIATION: This protection scheme outlined above has been used throughout the world for over 10 years. In locations where these systems have been installed, there have been no significant fire losses attributed to electrostatic paint spray operations.

Fire loss history has proven that the highest probability for fire in an automatic (i.e., electrostatic) paint operation is during non operating periods, when the listed equipment does not provide protection. The fire systems will provide protection.

The objective for requiring and using listed automatic electrostatic paint spray equipment is to reduce the risk to life or property. The protection scheme outlined in the exception provides equivalent protection to life and greater protection to property. COMMITTEE ACTION: Accept.

Change second sentence of (a) to read: "In addition to the requirements in 7-6..." COMMITTEE STATEMENT: The minor change is made to delete a confusing and inaccurate reference to 7-1.1. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 28 VOTE ON COMMITTEE ACTION:

AFFIRMATIVE: 25 NEGATIVE: 1 NOT RETURNED: 2 Bannister, Johnson

EXPLANATION OF NEGATIVE: DOBSON: The request for Listing exemption does not provide

adequate substantiation. The statement is made that "the highest probability of fires in an automatic (i.e., electrostatic) paint operation is during non operatingperiods." The highest frequency of fires in electrostatic spray paint fires reported to Factory Mutual has been during painting operations, ff the statement was correct there would be no difference in hazard between conventional and electrostatic spray equipment.

At least one of the major protection systems may not be operating when the operators are in the booth. Flame detection systems and the water spray systems they operate may be bypassed due to concern for accidental operation. Manually operated systems are frequently not operated in the event of a rapid developing, high heat release rate fire. This is due to the concern the operator has in getting out of the fire area.

The objective of Listing is to prevent fires. The protection contained in the exemption will not prevent fires and therefore will not offer "equivalent protection to life and greater protection to property."

(Log #12) 33- 44 - (11-3.1.3 Exception (New)): Accept in Principle SUBMITTER: Larry T. Medler, General Motors - Paint Engr. RECOMMENDATION: Add exception to Paragraph 11-3.1.3 as follows:

Exception: Unlisted portable electric infrared heaters shall be permitted on swing arms and /o r rail mechanisms provided all of the following conditions have been met:

(a) All electrical controls for the infrared heater are placed outside the spray booth.

(b) All electrical receptacles and terminal boxes shall be Class 1, Group D, Division 1.

(c) During spraying operations the infrared heater head shall be placed in the designated overspray-free area. The spray booths fresh make-up air shall pass through this overspray-free area before going to the actual spray area.

(d) An interlock shall be provided to ensure that the heater head is placed in the designated area before any spraying operations may begin.

(e) The infrared heater shall not contain any structure cavities which could trap solvent vapors.

(f) The painting operation is limited by using only hand held cup (gravity feed or suction feed) spray guns and with the total volume of paint used in an eight hour period to less than one gallon. SUBSTANTIATION: Portable infrared heaters used in spray booths today require the same interlocks and operations as any permanently mounted infrared unit referred to in NFPA 33. This change will clarify the situation of using portable infrared heaters which are mounted (not fixed and unique in the booth) on rails or arms for the operator ergonomics. Currendy no portable electrical infrared heaters are listed per die NFPA 33 requirement and none of the listing agencies have any standards for listing portable electric infrared heaters.

S U B S T A N T I A T I O N : Recently, a task g roup was set up to study NFPA 33 as concerns the automot ive ref inishing industry and the use of "prep stations" for spray pa in t ing of automobiles .

The task force unfortunately, only dealt with fixed prep stations and did not consider mobile units or anyth ing involving air recirculation.

After the task force made its proposal and recommenda t ions , they passed a TIA which was then passed a long to the Standards Commit tee . The Standards Commi t t ee me t and heard a lot of evidence and facts that had no t been p resen ted to the task g roup on this issue.

It appears tha t there needs to be two sets o f definit ions such tha t one set deals with a fixed l imited f in ishing workstation and the o ther that deals with a mobile or recirculat ion workstation.

The p rob lem becomes one of applicat ion out in the "real world" that canno t be addressed by a strictly adhe red to a one d imens ional set of rules that only pertains to fixed prep stations that exhaust to the outside and intake f rom the outside. This was the same p rob lem that the task g roup faced.

There has been t r e m e n d o u s advancements m a d e in the spray pa in t ing industry in the last ten years that make it safer than ever, such as:

1. The automotive paint companies have greatly changed the mixture of the paint product and the solvent content , so that there is less " thinners" in the p roduc t to be sprayed. This m ean s that there will be less vapors f rom the solvents to mix with the air du r ing a spray opera t ion a n d less chance of ignition.

2. The deve lopmen t of HVLP guns for spraying the p roduc t which allows the user to apply more of the paint p roduc t to the surface a n d less over spray in the air. This also means less solvents are released in the air du r ing a spray operat ion, a n d if the solvent concent ra t ions in the air are less, there is less chance of ignition. Again, this means less danger of fire.

3. The automot ive indus t ry has seen a rise in small spot jobs and therefore less of a need to pu t each a n d every j o b into full size pa in t booth. This has necessi tated the industry 's n eed to look at

178

N F P A 33 - - MAY 2000 R O P

how to best do small jobs as rapidly as they can and no t tie up expensive full size pa in t booths with a small job.

4. There have been great advancements in the technology with filters mad the filter industry. They are advanc ing so rapidly that no t even all of the filter manufac tu re r s can keep up with the new types of mult i layered, chemically t reated filters which can remove jus t abou t any th ing by one pass t h rough the filter. Activated carbon filters laminated with potass ium catch things tha t 10 years ago no filter could remove.

5. The Envi ronmenta l Protection Agency has had a major impact on direct d ischarge vapors into the a tmosphere . This means that there has to be a certain a m o u n t of f i l tering and collection of particulates and vapors tha t canno t jus t be puked ou t into the a tmosphere . Therefore , even the full size pa in t booths have to collect a certain a m o u n t of con taminan t s in their filters and on their walls and in their vents that can no longer jus t be vented outside.

6. Lastly, there have appeared many uses that unfor tunate ly canno t be easily categorized and make use of full size pa in t booths no mat ter how the regulat ions are written. For them, compl iance is impossible. A few examples of these uses are as follows:

(a) Remode l ing of a shop area at a s h o p p i n g mall. This is where one t enan t at the mall moves out and the landlord wants to remodel the a rea for the nex t tenant . W h e n the landlord starts his remodel ing, they general ly pu t up plastic sheets to protect the rest of the mall f rom the dus t and fumes as the r emode l ing project proceeds. Unfor tunately , it is impossible to br ing a full size paint booth to the area or to take the area to the full size paint booth. Some of these people have taken a recirculat ion and purification system into the area and while do ing the remodel ing , let it run by collecting the con taminan t s in the air and captured the vapors so that they are no t released into the rest of the mall area.

(b) The re are some isolated job sites where small parts need to be painted or p repped and it is unfeasible to move the small parts grea t dis tances to accompl ish this. An example of this is d a m sites and o ther opera t ions where space is at a p r e m i u m and the dis tance to the surface or to adequa te locale to pa in t is unfeasible.

Obviously, regula t ions canno t conceive of every prob lem that will arise in our society where a full size~aaint booth or f ixed prepara t ion workstation will work. T he re needs to be a balance or t radeoff in the rules and regulat ions so that society can progress at a reasonable pace without jeopard iz ing safety by fire or explosion.

The task g roup tha t looked at "prepara t ions worksta t ions- unfor tuna te ly did no t see any way that recirculat ion uni ts could fit into their defini t ions or feasibilities. I th ink that if real tests were pe r fo rmed to show the l ikelihood of fire or loss of life or property in a control led recirculat lon area as we have set t h e m for th in the p roposed 12-4, the risk would be minuscule . The re is no reason to pass a regulat ion like that p roposed by the task group, that is an overkill for such a small danger . W h e n you consider the vo lume of air m o v e m e n t in a recirculat ion unit , the a m o u n t o f spray, material used in the given length of t ime, the rate of evaporation of the part icular solvent and the use of the filtration system, recirculation workstations can be safe and can help towards alleviating the p rob lem of "open area spraying".

As you can see f rom our proposal, Sections 12-1 t h r o u g h 12-5.9 are pretty m u c h the changes tha t the task g roup had proposed. We have merely added Chapte r 12-4 to cover recirculation uni ts and all those workstations tha t involve spray f in ish ing operat ions to be pe r fo rmed on small areas or spot areas. Recirculat ion uni ts do not, no r shou ld they ever, replace the use of a full size paint booth. Recirculation uni ts are the answer to some prob lems that exist in the "real world." We need recirculation units, bu t they do have to be def ined a n d some limits placed upon their use.

We hope that you will consider put t ing our suggested 12-4 into the new NFPA 33 Edition. We thank you for your t ime and cons idera t ion . COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: T h e Technica l Commi t tee has developed new Sections 12-2 and 12-3 to address these units. The Commit tee ' s p roposed language is more technically valid in l ight of testing done prior to the deve lopment o f the text.

In addit ion, the Commi t tee notes that recirculation is already addressed in Section 5-5. Also, while carbon indeed absorbs vapors, it releases those vapors slowly, so exposure can still occur. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 28 VOTE ON COMMITTEE ACTION:

12-3.10 Recirculation of exhaust air shall be permitted only if all provisions of Section 5-5 are met. SUBSTANTIATION: Recently, the automotive refinishing industry has begun using so-called "prep stations" for spray painting of automobiles. Prep stations were initially intended and designed to provide a structure in which surface preparation (sanding, grinding, body-filler work) could be done and to provide some ventilation and filtration, so that fugitive dust could be controlled and not affect other areas of the shop. As use of these units expanded, shops began using them as inexpensive alternatives to a spray booth, as defined and governed by NFPA 33, Standard for Spray Application Using Flammable or Combustible Materials. Initially, the use was limited to spot priming and minor painting. However, this has evolved to the point where some shops use them instead of paint spray booths for all refinishing work, and some

manufacturers openly advertise them as suitable for all spray finishing operations.

Use of these prep stations is not currently addressed in NFPA 33, and NFPA 33 considers them to be open spray areas, regardless of any enclosure that might be provided. Typically, confinement is provided only by a flexible curtain or in some cases by an air curtain. These units typically meet few, if any, of NFPA 3Ys requirements for spray booths in such areas as construction, electrical equipment, exhaust ventilation, and fire protection.

A Tentative Interin~ Amendment to the 1995 edition of NFPA 33 to address these units was not successful. The Technical Committee has revised its initial proposals and has established two classes of units: limited finishing workstation and preparation workstation, and has developed appropriate requirements for the former.

This proposal properly identifies a preparation workstation as being equivalent to an open spray area and having to meet the requirements in NFPA 33 for such use, while establishing appropriate fire safety requirements for the limited finishing workstation.

A-13-7.2(b) Damage limiting construction should be designed based on information contained in Chapter 4 of NFPA 68, Guide for Venting of Deflagrations. Pred will represent the pressure the pressure resistant components can withstand and Pstat will represent the pressure the pressure relieving components will relieve at.

A-13-7.2(c) Where explosion venting is used, its design should be based on information contained in NFPA 68, Guide for Venting of Deflagrations. For explosion relief venting through ducts, consideration should be given to the reduction in explosion venting efficiency caused by the ducts. The ducts should be designed with a cross-sectional area at least as large as the vent, should be structurally as strong as the dust collector and should be limited in length to 20 ft. Since any bends will cause increases in the pressure developed during venting, vent ducts should be as straight as possible. If bends are unavoidable, they should be as shallow angled (i.e., have as long a radius) as practical. SUBSTANTIATION: The majority of powders used in powder coating operations are combustible dusts and do present a dust explosion hazard where they are being used and collected. Ventilation can usually be used to control this hazard in the spray booth and connecting ductwork used in the ventilation / recovery system. However, ventilation cannot be used to adequately control this hazard in the dust collector where the powder is recovered. Therefore, explosion protection is needed on these collectors. Currently, NFPA 33 does not specifically require this. It might be inferred from paragraph 13-7.4, but this paragraph is extremely vague on what needs to be protected and then, it only allows one option on protection, deflagration venting. NFPA 69 does provide other alternatives.

This proposal addresses these problems by specifically requiring explosion protection on dust collectors and then provides various options for protection.

The current 13-7.2 tries to address the issue of spray booths with integrated powder recovery systems by stating that protection measures should be applied. The only exception Iknow to this is that there are some FM Approved booths with integrated recovery

systems that have been specifically tested to show that they do not have an explosion hazard and therefore do not need protection. I do not know if any other testing organizations have done similar work. If the committee knows of such work, the exception can be modified accordingly. COMMITTEE ACTION: Accept in Principle.

Revise Section 13-7 to read as follows: 13-7" Ventilation, Dust Collection, and Explosion Protection 13-7.1 Ductwork. Where powder overspray in conveyed by means

of ductwork to a remote recovery system, the following shall apply: (a) Nondeposited, air-suspended powders shall be removed

form the spray operation to the powder recovery system. For systems connected by ducts to enclosed collectors, sufficient airflow shall be provided to maintain the exhaust duct at a powder concentration that will not exceed one-half the "minimum explosive concentration" (MEC) of the powder in use. [See 13- 7.1 (b) for exception]. If the MEC of the powder has not been established, then the exhaust duct powder concentration shall be maintained below 0.015 oz/ft 3 (15 g/m3) . Exhaust equipment shall bear an identification plate stating the ventilation rate for which it was designed ( f t3 /m3/hr ) .

(b) Where, by design, the coating operation is conducted at an exhaust duct concentration above 50 percent of the MEC, listed explosion suppression equipment shall be provided. (See NFPA 69, Standard on Explosion Prevention Systems.)

13-7.2 Air exhausted from the recovery system of a powder operation shall not be recirculated unless the concentration of particulate matter in the exhaust air has been reduced to a level that is considered safe for personnel occupational exposure and suitable equipment continuously monitors the filtration system to signal the operator and to automatically shut down the operation in the event the filtration system fails to maintain the air in this condition.

13-7.3" Enclosures. Enclosures shall either be listed for the specific application or shall be designed to resist the destructive effects of an internal deflagration. Any enclosure that is not so listed and is effectively tight, such as a spray booth, dust collector, powder recovery device, or other enclosure, shall be provided with one of the following:

(a) Deflagration venting. (b) A deflagration suppression system that meets the

requirements of NFPA 69, Standard on Explosion Prevention Systems.

13-7.4 Ventilation for fluidized beds and electrostatic fluidized beds shall be designed to effectively prevent escape of nondeposited powder from the enclosure.

13-7.5 Ventilation for spray booths shall be adequate to confine air-suspended powder to the booth and recovery system at all times.

A-13-7.3 A "tight" enclosure is one in which a deflagration is likely to produce a sustained overpressure of 0.1 psi. See NFPA 68, Guide for Venting of Deflagrations, for information on the design of deflagration vents. COMMITTEE STATEMENT: The Technical Committee has revised the entire section to effect editorial improvement and to address the issues raised by the submitter. The substantive changes made by the Technical Committee provide additional flexibility. NUMBER OF COMMITTEE MEMBERS ELIGIBLE TO VOTE: 28 VOTE ON COMMITTEE ACTION:

13-7.4 Powder coating booths where ventilation cannot keep the interior of the booth below 50 percent of the MEC shall be provided with explosion protection by one of the following means.

(a)* Locate the spray booth inside a room constructed of damage limiting construction (interior walls pressure resistant and exterior walls pressure relieving) or design the booth of damage limiting construction provided the relieving wail(s) relieve outside.

(b)* Locate the spray booth inside the building next to an exterior wall and equip the booth with deflagration vents that are ducted to the outside through vent ducts.

(c) Install a deflagration suppression system on the spray booth in accordance with Chapter 4 of NFPA 69, Standard for Explosion Prevention Systems.

(d) Design the spray booth to contain a deflagration in accordance with Chapter 5 of NFDA 69, Standard for Explosion Prevention Systems.

A-13-7.4(a) Damage limiting construction should be designed based on information contained in Chapter 4 of NFPA 68, Guide for Venting of Detlagrations. Pred will represent the pressure the pressure resistant components can withstand and Pstat will represent the pressure the pressure relieving components will relieve at.

A-13-7.4(b) Where explosion venting is used, its design should he based on information contained in NFPA 68, Guide for Venting of Deflagrations. For explosion relief venting through ducts, consideration should be given to the reduction in explosion venting efficiency cansedby the ducts. • The ducts should be designed with a cross-sectional area at least as large as the vent, should be structurally as strong as the spray booth and should be limited in length to 20 ft. Since any bends will cause increases in the pressure developed during venting, vent ducts should be as straight as possible. • If bends are unavoidable, they should be as shallow angled (i.e. have as long a radius) as practical. SUBSTANTIATION: Often times, ventilation can be designed to keep the interior of a powder coating booth below 50 percent of theMEC of the powder, thereby reducing the need for explosion protection. However, in some instances, such aa when the spray patterns from spray guns account for a good portion of the booth volume, ventilation cannot be used effectively to reduce the powder concentration below 50 percent of the MEC~ In instances such as these, explosion protecuon should be applied to the booth.

The current 13-7.4 is vague onjust what requires protection and then only allows deflagration venting. This proposal is specific on what needs protection and it preatenm options on different types of explosion protection that can be used, COMMITTEE ACTION'Rejec t . COMMITTEE STATEMENT: NFPA 68, Guide for Venting of Deflagcations, does not apply to deflagration pressure containment; this is covered by NFPA 69, Standard on Explosion Prevention Systems.
