Regulations and Guiding Documents All committee members are expected to behave in accordance with the Guide for the Conduct of Participants in the NFPA Codes and Standards Development Process. All actions during and following the committee meetings will be governed in accordance with the NFPA Regulations Governing Committee Projects. Failure to comply with these regulations could result in challenges to the standards-making process. A successful challenge on procedural grounds could prevent or delay publication of the document. The style of the document must comply with the Manual of Style for NFPA Technical Committee Documents.




General Procedures for Meetings • Use of tape recorders or other means capable of producing verbatim transcriptions of any

NFPA Committee Meeting is not permitted.

• Attendance at all NFPA Committee Meetings is open. All guests must sign in and identify their affiliation.

• Participation in NFPA Committee Meetings is generally limited to committee members and NFPA staff. Participation by guests is limited to individuals, who have received prior approval from the chair to address the committee on a particular item, or who wish to speak regarding public proposals or comments that they submitted.

• The chairman reserves the right to limit the amount of time available for any presentation.

• No interviews will be allowed in the meeting room at any time, including breaks.

• All attendees are reminded that formal votes of committee members will be secured by letter ballot. Voting at this meeting is used to establish a sense of agreement, but only the results of the formal letter ballot will determine the official action of the committee.

• Note to Special Experts: Particular attention is called to Section 3.3(e) of the NFPA Guide for the Conduct of Participants in the NFPA Codes and Standards Development Process in the NFPA Directory. This section requires committee members to declare any interest they may represent, other than their official designation as shown on the committee roster. This typically occurs when a special expert is retained by and represents another interest category on a particular subject. If such a situation exists on a specific issue or issues, the committee member shall declare those interests to the committee and refrain from voting on any action relating to those issues.

• Smoking is not permitted at NFPA Committee Meetings.

Committee Actions All public proposals and comments must be acted upon by the committee. The following actions are permitted by the Regulations Governing Committee Projects for disposition of comments.

Accept - The committee accepts the proposal or comment. Only editorial changes such as paragraph and section numbering, and corrections to spelling, capitalization, and hyphenation may be made.




Reject - The committee rejects the proposal or comment entirely. The committee may reject any comment that is incomplete, per the NFPA Regulations Governing Committee Projects. Accept in Principle - The committee accepts the proposal or comment with revision. The committee action must indicate the specific revisions to the proposed content, and the locations of each revision within the proposed wording or the document. Accept in Part - The committee accepts part of the proposal or comment and rejects the remainder. Only editorial changes such as paragraph and section numbering, and corrections to spelling, capitalization, and hyphenation may be made to the accepted portion. The committee action must indicate the specific parts that were accepted and rejected. Accept in Principle in Part - The committee accepts part of the proposal or comment with revision and rejects the remainder. The committee action must indicate the specific parts that were accepted and rejected, as well as the nature and location of each revision. Hold (Comment Stage Only) – The committee holds the comment to be considered as a proposal during the next revision cycle. One of the following conditions must be met:

(a) The comment introduces a concept that has not had public review by being included in a related proposal as published in the Report on Proposals.

(b) The comment would change the text proposed by the TC to the point that the TC would have to restudy the text of the Report on Proposals or other affected parts of the Document.

(c) The comment would propose something that could not be properly handled within the time frame for processing the report.




Committee Statements Any proposal or comment that is "Rejected", "Accepted in Principle", "Accepted in Part", "Accepted in Principle in Part", or “Held” must

include a committee statement, preferably of a technical nature, that provides the reasons for the action.

A committee statement is not required for any proposal or comment that is “Accepted”, but should

be included when the committee’s reasoning differs from the substantiation provided by the submitter.

New text to read as follows:Manufacturers of Fire Hood and Ventilation Equipment Shall make available to State Fire Marshal Offices Product

Installation and Service Manuals and provide timely Product Safety Bulletins for Dissemination to all Authorized andLicensed Fire Equipment Service Companies for all Fire Equipment Products Manufactured, Listed and Sold for Profit inthose States. Also, a label shall be visibly affixed to each hood stating its UL Listing and whether or not Duct andPlenum areas require protection by A listed fire suppression system. If the hood is of the water wash down type,installation manuals shall require the installation of stainless steel pipe.

This would greatly improve the level of professionalism, Training and Quality of Service Inspectionsconducted by Authorized, Licensed and Permitted Fire Equipment Service Personnel. Currently, there are manyoversights or mistakes routinely being made and identification of Service Companies or their Employees performing atSubstandard levels is difficult to distinguish. By adding this requirement to all Standards would ensure the availability ofproper training and flow of information. Non-Compliant issues could be readily identified and corrected. Fire EquipmentService Companies and/or their Service Employees which perform at substandard levels could be readily identified. Thepurpose for these Standards is to ensure Minimum Requirements. This amendment would accomplish the best of whatis achievable when it comes to protecting overall Public Safety and Property. It is time to reduce the politics and truly putPublic Safety where it belongs – First.Note: Supporting material is available for review at NFPA Headquarters.

Move 3.3.18 to the annex to read as follows:Depression A.7.1.4 Dips are depressions or cuplike places in horizontal duct runs in which liquids could

accumulate.

The term “dips” appears only once in the standard (paragraph 7.1.4). Most people would not think tolook in the definitions section for an explanation of this term. Moving the explanation to the annex with an asterisk in thebody (paragraph 7.1.4) makes sense for most users of the standard.

_______________________________________________________________________________________________Jayendra S. Parikh, Compliance Solutions International Inc.

Include a definition for Primary Filter to read:Primary Filter. A filter that provides a flame barrier, is listed in accordance with UL 1046, and is installed in the aperture

of an exhaust hood.Primary filter is mentioned in paragraph 6.1.3, however, it is not defined in this document. Various

types of grease filters and grease removal devices are used in the exhaust hoods and in the devices, equipment, andsystems used in commercial cooking operations. Some of these filters are referred to as the primary filter and thesecondary filter. These filters/terms need to be defined in this document. This proposal and another proposal for a newparagraph 3.3.25.4 for the secondary filter address this need.

_______________________________________________________________________________________________96- Log #32


Include a definition for Secondary Filter to read:Secondary Filter. A filter that is not a primary filter, is used in conjunction with or in addition to a primary filter either on

the upstream or downstream of the primary filter, in an exhaust hood or in the devices, equipment, and systems used inthe commercial cooking operations.

Grease filters that are not primary filters (as defined in the proposal for a new paragraph 3.3.25.3),such as mesh and other filters, are used in the exhaust hoods, air pollution control devices, and recirculating systems,and are referred to as the secondary filters. The primary purpose of using such grease filters is to remove additionalgrease particulates that are not removed by the conventional baffle grease filters typically used in the hoods and otherdevices, equipment, and systems used in the commercial cooking operations. This definition is needed to differentiatebetween the secondary and primary filter, which is referred to in paragraph 6.1.3.




Revise definition to read as follows:The time, in minutes or hours, that materials or assemblies have withstood a fire

exposure as determined by the tests, or methods based on tests, prescribed by this standard. established in accordancewith the test procedures of NFPA 251. [ 2009]

NFPA 251 has been withdrawn. NFPA 150 took the definition from NFPA 220, who took an olddefinition from NFPA 5000. The present definition in NFPA 500 reads as follows, and the proposal is consistent withthat (simply changing code to standard):

The time, in minutes or hours, that materials or assemblies have withstood a fire exposure asdetermined by the tests, or methods based on tests, prescribed by this code.




Revise text to read as follows:

Any material that will burn regardless of its autoignition temperature.(See 4.8.2) Refers to a building construction material not complying with the

definition of noncombustible material that, in the form in which it is used, has a potential heat value not exceeding 3500Btu/lb (8141 kJ/kg), where tested in accordance with NFPA 259,

, and includes either of the following: (1) materials having a structural base of noncombustible material, with asurfacing not exceeding a thickness of 1/8 in. (3.2 mm) that has a flame spread index not greater than 50; and (2)materials, in the form and thickness used, having neither a flame spread index greater than 25 nor evidence ofcontinued progressive combustion, and of such composition that surfaces that would be exposed by cutting through thematerial on any plane would have neither a flame spread index greater than 25 nor evidence of continued progressivecombustion, when tested in accordance with ASTM E 84,

; or UL 723, . [ 2009](See 4.8.1) A substance that will not ignite and burn when subjected to a fire.

Materials subject to increase in combustibility or flame spread index beyond the limits hereinestablished through the effects of age, moisture, or other atmospheric condition should be considered combustible. SeeTable A.3.3.38.

For further information, see NFPA 259,.

Materials that are reported as passing ASTM E 136 should be considerednoncombustible materials.

A material that complies with any of the following shall be considered a noncombustible material:(1)* A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn, supportcombustion, or release flammable vapors, when subjected to fire or heat(2) A material that is reported as passing ASTM E 136,

(3) A material that is reported as complying with the pass/ fail criteria of ASTM E 136 when tested in accordance withthe test method and procedure in ASTM E 2652,

. [ 7.1.4.1.1]Where the term limited-combustible is used in this Code, it shall also include the term noncombustible.

[ 7.1.4.1.2]The provisions of 4.8.1.1 do not require inherently noncombustible materials to be tested in order to be

classified as noncombustible materials. [ A.7.1.4.1]Examples of such materials include steel, concrete, masonry and glass. [ A.7.1.4.1.1(1)]

A material shall be considered a limited combustible material where all theconditions of 4.8.2.1 and 4.8.2.2, and the conditions of either 4.8.2.3 or 4.8.2.4 are met. [ 7.1.4.2]

The material does not comply with the requirements for a noncombustible material, in accordance with 4.8.1.1.[ 7.1.4.2.1]

The material, in the form in which it is used, exhibits a potential heat value not exceeding 3500 Btu/lb (8141kJ/kg), when tested in accordance with NFPA 259, .[ 7.1.4.2.2]

The material has a structural base of a noncombustible material with a surfacing not exceeding a thickness of1/8 in. (3.2 mm) where the surfacing exhibits a flame spread index not greater than 50 when tested in accordance withASTM E 84, or ANSI/UL 723,

. [ 7.1.4.2.3]The material is composed of materials which, in the form and thickness used, neither exhibit a flame spread

index greater than 25 nor evidence of continued progressive combustion when tested in accordance with ASTM E 84 orANSI/UL 723, and are of such composition that all surfaces that would be exposed by cutting through the material onany plane would neither exhibit a flame spread index greater than 25 nor exhibit evidence of continued progressive


Report on Proposals – June 2013 NFPA 96combustion when tested in accordance with ASTM E 84 or ANSI/UL 723. [ 7.1.4.2.4]

Where the term limited-combustible is used in this Code, it shall also include the term noncombustible.[ 7.1.4.2.5]

NFPA 101 and 5000 have been revised so that the definitions of noncombustible material and oflimited combustible material have been eliminated and replaced by sections in the code or standard that will now be theplace that contains requirements for the use of the concepts. Definitions are not enforceable in NFPA documents andshould not contain requirements.The choice of the sections in chapter 4 where references to limited combustible material and noncombustible material

are placed was based on where these terms are used.

: The generic language describing clearance reduction systems incorporating mineral wool orceramic fiber insulation are outdated. The purpose of the proposed code is to improve the Standard by adding analternate tested exception to the grease duct clearance requirements in 4.2.3.2.

There continues to be confusion in the application of NFPA 96 requirements by manufacturers, designersand code users regarding the requirements relating to clearances versus the requirements regarding grease ductenclosure materials. Part of this confusion has been the fact that the grease duct clearance requirements are located in4.2, whereas the grease duct enclosure provisions, which also talk about clearances from the duct to the interiorsurfaces of enclosures of combustible or non-combustible construction, are located in 4.3 and 7.7. This proposal seeksto clarify that Listed and Labeled systems (permitted by 4.3), which are also tested and approved for their clearance tocombustibles, can be installed in accordance with their Listings.All manufacturers of field-applied grease duct enclosure systems have as part of their listings for each systems, an

allowable for clearance from the outside of the enclosure system to adjacent combustibles. They achieve this based onthe type, quantity, and method of installation of the protective enclosure materials, and test them in accordance with theASTM E2336 Standard recognized in 4.3.1.2. In fact, ASTM E2336 is designed to evaluate for zero clearance. Mostfield-applied grease duct enclosure system manufacturers have listings for Zero Clearance.The materials are routinely used as an option for reducing clearances, particularly in cases where there is a limited

amount of space available for other means of protection. Another typical use is in a 1 story restaurant where no ratedwall/ceiling is being penetrated, but field-applied protection is installed because of the proximity of the grease duct toadjacent combustible construction.

Add a new text to read as follows:Mesh Filters shall not be used as the primary grease removal device whether listed or not.

When used as primary grease removal devices, mesh filters add system resistance with face loading.In retrofit applications, the added resistance negatively affects fan performance, resulting in loss of ability to providecapture and containment of effluent, and upsetting the original (engineered) kitchen air balance. Mesh filters operate onthe impaction principle of operation, and as such, the primary grease removal devices cannot drain; this increases thefire hazard and can contribute to flame spread into the plenum and duct in an appliance fire condition.

I have been in the grease exhaust system cleaning business in Massachusetts for 22 years. Thisyear the MA Dept of fire Services mandated that hood cleaners be licensed by the state. This licensing brought on moreopen lines of communication between hood cleaners and the Fire Marshals than ever before. We came upon an issuewhich it was recommended by the Fire Marshals, that it be brought to the NFPA's attention.Regarding filters. It seems that most hood cleaners on various forums are in agreement that aluminum baffle filters do

not meet the codes. They only meet one, they are UL listed. UL standards require that the filter by able to condenseairborne grease and run it off. No testing for strength or resistance to a fire! As for being made of an equivalent materialto steel, no. As to holding up to the rough treatment common in the industry. No.Additionally each time we clean the filter they degrade, actually very quickly. If the restaurant runs them thru the

dishwasher where the chemical strength is very high they fall apart even quicker. With the combination of being a weakmetal at the start and constant degradation from cleaning they become much too thin to offer much resistance to a fire.In conjunction the filter is usually held together with aluminum rivets which are weakened even more quickly than thefilter itself.After doing some research I found that filter companies will offer the fact that galvanized filters can stand up to 450

degrees and stainless steel 900. Aluminum...not a word. The temperature at which aluminum breaks down inconspicuously omitted. Everywhere, not a word. Could it be the temperature is lower than the average fire? Imaginethe reduction in effectiveness after several cleanings. Baffles much thinner than when they were initially purchased.Another concern I thought you might consider is, say a fire breaks out in a hood. All the personnel evacuate and the

firemen come in. The aluminum filters, when they break down and burn emit toxic fumes that can kill. The only peopleexposed to these fumes will be the firefighters. Not a good thing. Their job is dangerous enough without this oversight.

Hopefully you will take this into consideration during the next NFPA 96 codes meeting.

Revise 11.1.6.1 to read as follows:Where the fire-extinguishing system or exhaust system is nonoperational or impaired, the systems shall be

tagged as noncompliant, and the system owner or owner’s representative shall be notified in writing of the impairmentand where required, the authority having jurisdiction shall be notified.

Correlation with NFPA 17A, proposal 17A-81 (paragraph 7.3.3.4.1), which reads as follows:“Until such repairs are accomplished, the systems shall be tagged as non-compliant, and the owner or owner’s

representative responsible for the system shall be notified and where required, the authority having jurisdiction shall benotified of the impairment.”

Revise text to read as follows:The fusible links shall be destroyed when removed. Destroyed fusible links from the most recent inspection shall

remain on site for inspection by the authority having jurisdiction.Destroyed fusible links should be kept on site so they can be viewed by the authority having jurisdiction.

There is no way to know if the links have been removed or “recycled” between systems unless they are available forviewing.




Change text as shown below: Fusible links on fire damper assemblies shall be replaced at least semiannually

. or more frequently as necessary.This proposal is intended to revisit a discussion about risk rationalization begun by the US General

Services Administration during the last cycle. (Refer to Proposal 96-110 (Log #76) authored by Joshua Elvove.)In general, fixed interval inspection, testing, maintenance and replacement of any safety element -- including fusible

links -- is not always effective use of the grim O&M funding.. In the education facilities industry, there is a broad rangeof cooking operations that span in scale from the local elementary school to large university-affiliated health caresystems with several commercial cooking facilities in hospitals.Some of the statements in the negative ballots are worth revisiting; two of them reproduced here for the convenience of

the committee:…"To ensure requirements for fire damper fusible links are in concert with similar requirements for fusible metal alloy

sensing elements serving kitchen fire extinguishing systems. Fire damper fusible links should not have to be replacedevery 6 months if located where not subject to contaminant loading such as low-volume cooking operations, such aschurches, day camps, seasonal businesses, or senior centers (permitted to be inspected for grease building up annuallyper Table 11.4). If grease build-up inspections can be conducted annually, there’s no need to replace fusible links moreoften."……"The date of manufacture marked on fusible links does not limit when they can be used. These devices have

unlimited shelf life. The intent of 11.3.2 is to require semiannual replacement of fusible links that have been installed inenvironments that subject them to containment loading, such as grease in restaurant hoods and ducts, that couldadversely affect their proper operation. Without technical substantiation, the persistence of this requirement looks likewriting a revenue stream. The greater risk lies in adopting jurisdictions simply ignoring the requirement."What each of the foregoing statements have in common is a recognition that generic, one-size fits all approaches are

not as effective in increasing fire safety as more risk-informed approaches that are scaled to the risks inherent in theprotected premises and the scale of the cooking operation.…

Revise text to read as follows:Except as permitted in 14.3.4, eExhaust systems serving solid fuel cooking equipment, including gas or

electrically operated equipment, shall be separate from all other exhaust systems.* Gas or electrically operated equipment that utilize solid fuel for flavoring, where the solid fuel provides less

than 5% of the heat contribution for cooking shall comply with 14.8, but shall not be required to have a separate exhaustsystem. Cooking processes, including, but not limited to, those that use any solid fuel for cooking enhancement orsmoke flavoring, shall comply with 14.3.3 and Section 14.8.A.14.3.4 * Using small quantities of wood chips or wood strips for flavoring, provides little or no heat contribution for

cooking, and does not add significantly to the class A products of combustion exhausted during the cooking process.Verification of the heat contribution can be made by 1) Making theoretical calculations of the potential heat contributionfrom the wood and comparing that to the heat contribution from the gas or electric power, or, 2) measuring cookingsurface temperatures with and without wood chips or strips, or 3) other means acceptable to the authority havejurisdiction.

The requirement for separate exhaust systems causes an onerous unjustified cost when addingsmoke flavoring to existing gas or electric cooking equipment. The attached documentation shows that the impact onthe surface temperature of the cooking equipment using wood strips for flavoring was negligible . UL uses the sameprotocol for testing duct extinguishing systems serving gas fired, electric fired, and solid fuel cooking equipment. Theincreased cleaning requirements in 14.8 will offset the minor changes that a small amount of wood smoke could causeon the surface coating inside the hood and exhaust system. While a 5% limit is somewhat arbitrary, it does provide ameasurable guideline that can be imposed if the quantity of wood used in the process appears to be excessive to theauthority having jurisdiction.Note: Supporting material is available for review at NFPA Headquarters.

Add new text to read as follows:(1) Cooking surface, duct, and plenum protection shall be provided. Additional duct nozzle(s) shall be provided at the

bottom of the downward duct section directing the discharge up. Additional nozzle(s) shall be provided facing across thehorizontal bottom duct section and additional nozzle(s) shall be provided to protect any duct section that subsequentlyrises vertically with the discharge directed upward.

The UL 300 protocol requires fire suppression system to function with the exhaust fan either on or off.The protocol does test downdraft duct constructions. If the exhaust fan is off at the time of a system discharge there isuncertainty about the extinguishing agent’s ability to reach all duct sections. Adding additional nozzles at these criticalchanges in elevation/direction could provide the needed protection.

Revise this information to read:Filters are expected required to minimize limit the projection of flames to a maximum of 18 inches

downstream when attacked by flame on the upstream side, and are expected to maintain their strength, shape, andintegrity when exposed to the anticipated rough handling, cleaning or replacement, and service found in the field.

Grease filters that are removable as defined in paragraph 3.3.25.1 for which this information has beenprovided, are required to be listed in accordance with UL 1046, as specified in paragraph 6.1.2. UL 1046 requires thatduring the flame exposure test, no flame extension greater than 18 inches occurs beyond the downstream face of thefilter. The proposed changes reflect this requirement. Also, some grease filters available today are not to be cleaned, butare to be disposed of when loaded with grease, and replaced with new filters. The proposed change addresses suchfilters.

Revise the sentence in this paragraph beginning with “When to clean:” by deleting the latter part ofthat sentence, to read as follows:

A measurement system of deposition should be established to trigger a need to clean, in addition to atime reference based on equipment emissions.

This information should be revised as proposed above, because: (1) “time reference” such as monthly,quarterly, and semiannually and “equipment emissions” such as from char-broilers, fryers, and ovens should relate &apply to frequency of inspection as specified in Table 11.4 in this document, and not to the frequency of cleaning, (2)use of high efficiency grease filters and other new technologies used in the hoods which reduce grease accumulation inthe kitchen exhaust system (KES) extends frequency of cleaning the KES, (3) hence the “time reference” for cleaningthe KES based on “equipment emissions” without taking into account the volume of cooking as mentioned in Table 11.4in this document and amount of grease accumulation in the KES, is subjective, and not appropriate, and (4)measurement of grease deposition, mentioned in the first part of this sentence, to trigger a need for cleaning should bethe only criteria for when to clean, and not also the time reference.
