Consideration should be given to approaching NFPA 1 on this topic. Section currently addresses temporary and mobile cooking operations.

8 of 123 7/30/2015 1:48 PM Public Input No. 22-NFPA [ New Section after ] Commercial Cooking Operations. Cooking operations that are concerned with or engaged in commerce. Application of this Standard is difficult when the core term of the document is not defined. It is understood that the Standard can be applied to commercial and residential cooking equipment, but the cooking equipment has nothing to do with the question of whether or not the cooking operations are considered commercial. How can section for residential cooking equipment be enforced if the enforcer does not know what commercial cooking is? If the committee does not agree with the proposed definition, we would ask the committee to provide one. Submitter Full Name: Doug Hohbein Organization: Northcentral Fire Code Develop Submittal Date: Tue Apr 22 16:35:23 EDT 2014 Resolution: Section and and identifies the scope of this document.

13 3 of 123 7/30/2015 1:48 PM Public Input No. 124-NFPA [ Section No ] The responsibility for inspection, testing, maintenance, and cleanliness of the ventilation control and fire protection of the commercial cooking operations shall, including cooking appliances, shall ultimately be that of the owner of the system, provided that this responsibility has not been transferred in written form to a management company, tenant, or other party. Numerous fires in commercial cooking operations are caused by ignition of grease in and around appliances, particularly in places that are not within the zone of protection of the extinguishing system. Section 11.7 specifies requirements for cleaning appliances of accumulated grease. Adding the proposed text emphasizes that the responsibility for assuring that this cleaning gets done, is that of the owner.

The current wording of implies only UL 2221 tested and listed systems are acceptable to be factory-fabricated. Submitter Full Name: Gerry Saieva Organization: DuraSystems Barriers Inc Submittal Date: Thu Jul 10 14:25:39 EDT 2014 Resolution: UL 2221 is the minimum standard for factory-built grease duct protection systems. Factory built assemblies can be also classified for compliance with ASTM E 2336, in addition to listing in accordance with UL2221.

19 9 of 123 7/30/2015 1:48 PM Public Input No. 121-NFPA [ Section No ] Listed grease filters and grease removal devices that are removable but not an integral component of a specific listed exhaust hood shall be listed in accordance with ANSI/UL 1046, and shall be clearly so designated on the face of the filter as to be visible as to be visible with the filter installed.. NFPA 96 requires all grease removal devices to be listed to ANSI/UL 1046 however non-listed filters are readily available in the marketplace, and are commonly found employed in the field. These filters are inexpensive, and are being sold to unsuspecting end users in lieu of the 1046 listed filters that are required. Having the grease removal devices clearly marked on the front will allow inspecting authorities and end users to easily identify that the employed grease removal devices align with the requirements of the standard. Submitter Full Name: Bernard Besal Organization: Besal Services, Inc. Affilliation: International Kitchen Exhaust Cleaning Association (IKECA) Submittal Date: Fri Jan 02 15:59:21 EST 2015 Resolution: FR-9-NFPA Statement: NFPA 96 requires all grease removal devices to be listed to ANSI/UL 1046 however non-listed filters are readily available in the marketplace, and are commonly found employed in the field.

Grease filters that require a specific orientation to drain grease shall be clearly so designated on the face of the filter as to be visible with the filter installed, or the hood shall be constructed so that filters cannot be installed in the wrong orientation. Authorities having jurisdiction, inspection entities, and end users will have clear indication on the required orientation of the grease removal devices without having to remove the grease removal devices from the exhaust hood. Submitter Full Name: Bernard Besal Organization: Besal Services, Inc. Affilliation: International Kitchen Exhaust Cleaning Association (IKECA) Submittal Date: Fri Jan 02 15:42:55 EST 2015 Resolution: FR-11-NFPA Statement: UL 1046 requires a visible mark on the face of the filter to show the filter orientation. As an option, users will have clear indication on the required orientation of the grease removal devices without having to remove the grease removal devices from the exhaust hood.

22 2 of 123 7/30/2015 1:48 PM Public Input No. 71-NFPA [ New Section after ] TITLE OF NEW CONTENT Exception: Factory-built listed grease ducts shall be permitted to be installed at a slope lower than that specified in 7.1.4, in accordance with the lower slope specified in the manufacturer's installation instructions. This exception would permit installation of factory-built listed grease duct at a slope lower than that specified in this standard. Recently revised UL 1978 (the standard used for listing grease duct) allows for duct installation at lesser slope than that specified in section 7.1.4, when the lesser slopes have been shown through analysis, tests, or both to provide equivalent or better flow characteristics, as compared to field-installed (which are rectangular) grease ducts with code prescribed minimum slopes (as specified in 7.1.4), and the manufacturer's installation instructions include a statement regarding the installation at not less than the lesser duct slope which is approved by the listing agency. The installation instructions, which are a required part of a factory-built grease duct listing, of manufacturers of such grease ducts include a statement regarding installation of their grease ducts at not less than the lesser duct slope that the listing agency has approved. Submitter Full Name: Jayendra Parikh Organization: Compliance Solutions International Inc Affilliation: Self Submittal Date: Tue Dec 02 19:12:51 EST 2014 Resolution: FR-14-NFPA Statement: The previous edition did not refer to a lesser slope.

The proposed change will clarify this requirement. The phrase that is proposed to be deleted does not make sense, as it is written/included in this section. Also, grease duct drains are not listed. If the drains are provided with listed grease duct, they are components of that grease duct. Submitter Full Name: Jayendra Parikh Organization: Compliance Solutions International Inc Affilliation: Self Submittal Date: Mon Dec 15 19:02:31 EST 2014 Resolution: FR-15-NFPA Statement: The proposed change will clarify this requirement.

25 5 of 123 7/30/2015 1:48 PM Public Input No. 123-NFPA [ New Section after ] TITLE OF NEW CONTENT Type your content here Factory-built grease duct systems shall conform to the accessibility requirements specified in section 7.4. Factory-built grease duct systems consist of components and fittings and access to the interior of the exhaust duct is provided by installation of wyes and tees. Adding access to factory-built duct systems after assembly of the sections is impossible due to impact on the listings of the assembly. Factory-built ductwork is often installed with less frequency of access, and many installations are found where the tees and wyes intended for use as access points have interferences. On smaller diameter factory-built ducts, the frequency and placement of the access is critical to facilitate long term fire-protective cleaning. The proposed change aligns access requirements for fabricated and factory-built ducts. Submitter Full Name: Bernard Besal Organization: Besal Services, Inc. Affilliation: International Kitchen Exhaust Cleaning Association (IKECA) Submittal Date: Fri Jan 02 18:44:10 EST 2015 Resolution: Language for accessibility is currently adequate.

26 Public Input No. 23-NFPA [ Sections , ] Sections , Buildings less Enclosures less than four stories levels in height shall have an enclosure with a fire resistance rating of not less than 1 hour Buildings Enclosures four stories levels or more in height shall have an enclosure with a fire resistance rating of not less than 2 hours. It is unclear if the intent is to provide a fire rated enclosure based on the height of the building or the number of stories penetrated by the exhaust duct. If a duct penetrates only one floor of a six-story building, is the enclosure required to be two-hour fire rated? If the intent is number of levels in the building, should basements or lower levels that are not considered stories be counted? Submitter Full Name: Doug Hohbein Organization: Northcentral Fire Code Develop Submittal Date: Tue Apr 22 16:36:55 EDT 2014 Resolution: The current language is consistent with other industry standard terms. 6 of 123 7/30/2015 1:48 PM

Passing this test gives the fire system an "unlimited protection" Listing. We are involved in projects where the duct work is several hundred feet long, sometimes going straight up and others with horizontal ducts and making many turns before reaching the exhaust fan. There is no data, that I am aware of, that ensures a fire beyond 75 feet will be extinguished. Requiring an independent system, with its own detection system, will the system to discharge when needed and extinguish the system Hoods that share a common exhaust duct but are separated by walls should have their own independent fire extinguishing systems. We recently had a project where there were 43 hoods, most separated by walls or located in different rooms and all on one common exhaust duct. Because of current it was required that all 43 hoods had to simultaneously discharge. Even if it was just 2 hoods, installed in different rooms, there is still a problem. The following is rational for our proposal: For an example, assume there are 3 hoods separated by walls and there is a fire in Hood # 1, the fire is detected and all three fire systems simultaneously discharge; 1. If the fire spreads to Hood #2, will the chemical that has already sprayed all over the cooking appliances, hood plenum, and up the duct, extinguish the fire or prevent grease or other material from igniting. We are not aware of any tests or data proves this. 2. The personnel around Hood #1, will certainly be aware of the fire and will deal with it, even anticipating the fire extinguishing system discharging. The personnel around Hoods #2 and #3 may have no idea that Hood #1 is involved in a fire, and so when their Hoods fire extinguishing system discharges it's a complete surprise. If anyone is cooking under the hood, will the chemical harm their skin, or worse yet what if they happen to be looking up when the system discharges. What if maintenance, such as removing filters, replacing light bulbs etc. were being conducted when the system discharged. We believe simultaneous discharge is actually a hazard. Why not just allow the fire extinguishing system to react when there is a fire under the hood it serves (New) The rational for this proposal is the same as our proposal for and (New) and is as 9 of 123 7/30/2015 1:48 PM

Given the design of any particular cooking area, meeting this spacing requirement is often difficult and impractical. By requiring the manual activator to be between 10 ft. and 20 ft. from the protected hood often requires building a structure for the sole purpose of mounting the manual activator. In some instances the kitchen door is right next to the cooking area and the manual activator should be located at that point of egress. Although the current wording does allow for flexibility by the AHJ, often times this is viewed as an absolute requirement. Removing this requirement will give the AHJ more discretion to assure the manual activator is located in a practical location in the path of egress. The location recommendation will be moved to the Annex, A , a separate proposal has been submitted to cover this new annex material.

Renumber existing to and remaining sections of 10.7.) Fixed automatic fire-extinguishing systems shall have a visual means to indicate that the propellant vessel is pressurized to its required pressure. Many chemical fire extinguishing systems use a pressurized gas cartridge, that when mechanically punctured, propels the chemical through the piping and then discharging through the nozzles. The problem is that this cartridge is not monitored. The fire extinguishing system may be cocked and ready, but the cartridge may not be pressurized or not in place. Without monitoring, the kitchen staff has no idea that the system in not ready to discharge if there is a fire. We have many service agencies that are also fire extinguishing systems contractors, and we have heard many instances of cartridges laying in the bottom of the system cabinet, or in place but previously punctured.

70 0 of 123 7/30/2015 1:48 PM Public Input No. 155-NFPA [ New Section after ] TITLE OF NEW CONTENT Class "B" gas-type clean agent extinguishers shall not be permitted in kitchen cooking areas. The technical committee needs to again address this specific fire extinguisher reference within commercial kitchens. The prohibited placement of clean agent types of portable fire extinguishers within commercial kitchens has been a long standing requirement, that was inadvertently removed from the 2011 edition of NFPA-96. Clean agent fire extinguishers have a history of attempted use on cooking appliance fires, prior to activating fire suppression systems. Activation of the fire supression system prior to the utilization of any extinguisher, is essential to address hidden fire typically present within the hood and exhaust duct, as well as shut down of all heat sources under the hood. The premature removal of heat generated from cooking applance fires with an extinguisher, can essentially disable the automatic detection and activation of such systems until the building structure is severely involved. Existing extinguisher requirements within NFPA-10 and NFPA-96 specifically restrict the use of installed class K extinguishers till after the suppression system has been activated. Reference the existing equipment labeling and placard requirements within commercial kitchen applications. The suggested "clean agent" term was added for additional clarification of the specific type of extinguishers being addressed. Submitter Full Name: J.

Any H2O measured in the sample is antagonistic to fire, and cannot logically be used as an risk measurement additive or contributing factor to a fire hazard. The use of the word "vapors" is misapplied in this standard. condensible particulates are instantly condensed when they come in contact with room air. The mean temperature of exhaust air even over high temperature cooking operations rarely exceeds 200F. Combustible particulate matter at these temperatures are not in a gas phase. Accordingly, cooking operations are outside of the scope of EPA test method 202. EPA 202 is the appropriate test for power plants smoke stacks and other industrial processes where gasses from various industrial processes are captured and exhausted from stacks.

86 5 of 123 7/30/2015 1:48 PM Public Input No. 134-NFPA [ Section No ] * Gas-operated equipment utilizing solid fuel for flavoring that meets all the following conditions shall not be required to have a separate exhaust system: (1) * The solid fuel holder (smoker box) shall be listed with the gas-operated equipment. (2) The solid fuel holder shall be located underneath the gas burners. (3) Spark arresters conforming with shall be provided. (4) * The maximum quantity of solid fuel consumed shall not exceed 2.45 kg ( lb) per hour per kw 3kW (100,000 Btu/hr) of gas burner capacity. (5) The gas-operated equipment shall be protected by a fire suppression system listed for the equipment, including the solid fuel holder. (6) Gas-operated equipment with integral solid fuel holder(s) intended for flavoring, such as radiant charbroiler(s), shall comply simultaneously with the requirements of ANSI/UL 300 that address that gas radiant charbroiler(s) and mesquite wood wood charbroiler(s). (7) A fire suppression system nozzle(s) shall be installed to protect the solid fuel holder. (8) The fire suppression system shall be designed and installed to protect the entire cooking operation. (9) Each solid fuel holder shall be limited to a size of L ( in. 3 ), with no dimension to exceed 51 cm (20 in.). (10) A maximum of one solid fuel holder for each 29.3 kw (100,000 Btu/hr), or portion thereof, of burner capacity shall be permitted. (11) Solid fuel shall be immersed in water for a continuous period of at least 24 hours immediately prior to being placed in the cooking equipment. (1 1 2) The inspection frequency shall be the same as for solid fuel cooking operations in Table Gas-operated equipment utilizing solid fuel for flavoring that meets shall be inspected, cleaned, and maintained in accordance with Section During the last cycle of this standard, a proposal was made to allow solid fuel (wood) to be utilized in char broilers for flavoring, and to treat that operation differently than cooking with solid fuel, specifically to delete the requirement for a separate hood system for these operations. The original proposal was to limit the amount of wood to an amount that would contribute less than five percent of the total amount of heat used for cooking. The proposal was based upon a study conducted by the proponent and the policies and procedures of a major restaurant chain. The committee accepted the proposal in principle, but invoked a series of requirements to address concerns expressed by the committee and others. The results of the committee s revisions of the original proposal are that the amount of fuel allowed is far more than what was used in the study, and more than is used by the major restaurant chain. This comment addresses that issue by revising the maximum amount of fuel permitted to the same amount used in the study. To allow greater amounts of fuel is to increase the hazard without justification; this change simply adheres to the parameters of the study.

87 6 of 123 7/30/2015 1:48 PM The other change is to require that the wood be soaked in water prior to being placed in the broiler. This is consistent with the study used to justify the original change, and is consistent with the procedures used by the major restaurant change. This proposal should not be controversial; it is simply bringing the language that was inserted into the standard in line with the justification provided for the proposed change.

88 7 of 123 7/30/2015 1:48 PM Public Input No. 68-NFPA [ Section No [Excluding any Sub-Sections] ] For fire-extinguishing equipment on downdraft appliance ventilation systems, the following shall apply: (1) Cooking surface, duct, and plenum protection shall be provided. (2) At least one fusible link or heat detector shall be installed within each exhaust duct opening in accordance with the manufacturer's listing. (3) A fusible link or heat detector shall be provided above for each protected cooking appliance and in located in the plenum area of that appliance or in accordance with the extinguishing system manufacturer s listing. (4) A manual activation device shall be provided as part of each appliance at a height acceptable to the authority having jurisdiction. (5) Portable fire extinguishers shall be provided in accordance with Section Downdraft appliances do not have an overhead hood where detectors can be placed. The exhaust from these appliances does not go up into an overhead hood but rather down into the downdraft plenum. Placing a detector above a downdraft appliance is impractical and would not provide timely system activation because the heat generated by a fire on the cooking surface is drawn into the downdraft plenum. This is where the detector should be placed. Additionally, NFPA requires that an interlock be provided on downdraft cooking appliances so the appliance cannot operate unless the ventilation system is activated.

102 Public Input No. 72-NFPA [ Chapter A ] Annex A Explanatory Material Annex A is not a part of the requirements of this NFPA document but is included for informational purposes only. This annex contains explanatory material, numbered to correspond with the applicable text paragraphs. 9 of 123 7/30/2015 1:48 PM

103 0 of 123 7/30/2015 1:48 PM A These requirements include, but are not limited to, all manner of cooking equipment, exhaust hoods, grease removal devices, exhaust ductwork, exhaust fans, dampers, fire-extinguishing equipment, and all other auxiliary or ancillary components or systems that are involved in the capture, containment, and control of grease-laden cooking effluent. A This judgment should take into account the type of cooking being performed, the items being cooked, and the frequency of cooking operations. Examples of operations that might not require compliance with this standard include the following: (1) Day care centers warming bottles and lunches (2) Therapy cooking facilities in health care occupancies (3) Churches and meeting operations that are not cooking meals that produce grease-laden vapors (4) Employee break rooms where food is warmed A This standard cannot provide safe design and operation if parts of it are not enforced or are arbitrarily deleted in any application.

104 A 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, procedures, equipment, or materials, the authority having jurisdiction 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 that is concerned with product evaluations and is thus in a position to determine compliance with appropriate standards for the current production of listed items. A Authority Having Jurisdiction (AHJ). The phrase authority having jurisdiction, or its acronym AHJ, 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 having jurisdiction. A Listed. The means for identifying listed equipment may vary for each organization concerned with product evaluation; some organizations do not recognize equipment as listed unless it is also labeled. The authority having jurisdiction should utilize the system employed by the listing organization to identify a listed product. A Appliance Flue Outlet. There might or might not be ductwork attached to the opening(s). A Certified. Certification can be provided by the manufacturer of the listed equipment being serviced or an independent third party. A Construction. See Figure A Figure A Examples of Open and Closed Combustible Construction. A Continuous Weld. Welding is a fabrication technique for joining metals by heating the materials to the point that they melt and flow together to form an uninterrupted surface of no less strength than the original materials. For the purpose of the definition, it specifically includes the exhaust compartment of hoods and welded joints of exhaust ducts yet specifically does not include filter support frames or appendages inside hoods. 1 of 123 7/30/2015 1:48 PM

105 A Solid Fuel Cooking Equipment. This equipment includes ovens, tandoori charcoal pots, grills, broilers, rotisseries, barbecue pits, and any other type of cooking equipment that derives all or part of its heat source from the burning of solid cooking fuel. A Grease Filter. Filters should limit the projection of flames after grease loading, in accordance with ANSI/UL 1046, Standard for Grease Filters for Exhaust Ducts, to a maximum of 457 mm (18 in.) downstream when attacked by flame on the upstream side. They are expected to maintain their strength, shape, and integrity when exposed to the anticipated rough handling, cleaning, and service found in the field. A Grease. Grease might be liberated and entrained with exhaust air or might be visible as a liquid or solid. A Hood. The term hoods as used in this document often refers to Type I hoods, meaning those applied to grease exhaust applications. They are built in various styles, for example, single- or double-island canopy, wall-mounted canopy, noncanopy, backshelf, high sidewall, eyebrow, and pass-over style. All such type and style hoods are applicable to this document, provided they meet all the material and performance requirements of this document. (See Figure A ) Figure A Styles of Hoods. The following are types of hoods: (1) Type I. Hoods designed for grease exhaust applications. (2) Type II. Hoods designed for heat and steam removal and other nongrease applications. These hoods are not applicable to the standard. 2 of 123 7/30/2015 1:48 PM

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

107 4 of 123 7/30/2015 1:48 PM A See ANSI/UL 710B, Standard for Recirculating Systems. A When solid fuel is burned in cooking operations, increased quantities of carbon, creosote, and grease-laden vapors are produced that rapidly contaminate surfaces, produce airborne sparks and embers, and are subject to significant flare-ups. Also, solid fuel cooking requires fuel storage and handling and produces ash that requires disposal. For these reasons, solid fuel cooking operations are required to comply with Chapter 14. A The authority having jurisdiction can exempt temporary facilities, such as a tent, upon evaluation for compliance to the applicable portions of this standard. Although it might not be practical to enforce all requirements of this standard in temporary facilities, the authority having jurisdiction should determine that all necessary provisions that affect the personal safety of the occupants are considered.
