These were as follows: Mobile/Self propelled/portable Equipment Sprinklers NFPA 120 Sections and Task Force MCC Room Detection/Protection 7.0 The committee acted on the work of the mobile/self propelled task group and the 122 task group. This work was input as second revisions for both 120 and 122. Susan will create a draft of the work of the sprinkler task group as a word file with changes tracked. This will be distributed to the committee for review and also be distributed to a task group from the NFPA 13 Technical Committee for comment. Depending on the results of the NFPA 13 review, the committee may need to have a conference call to finalize the second revisions. Susan and Matt will schedule this meeting, if needed, once comments are received. This will be a continuation of the second draft meeting. 8.0 Tom Delorie discussed the need for the development of fire protection requirements for spirals. The possibility of handling this by a TIA was discussed by the committee. Matt will send out an e mail to the technical committee in an effort to explore this option 9.0 The next meeting of the technical committee will be held for the first draft of the next revision cycle, in the spring of Page 2 of 2

9 1 of 50 2/21/2018, 1:28 PM Public Input No. 34-NFPA [ Global Input ] Add a chapter 12 to the document to cover wet chemical suppression. The chapter will contain chapters 4, 5, 6, and 7 of NFPA 17A as edited in the attached document titled DBrohmer_ All definitions of NFPA 17A used in chapters 4, 5, 6, and 7 will be added to chapter 3 of NFPA 120. All annexes to the sections in chapters 4, 5, 6, and 7 of NFPA 17A will be added to Annex A of NFPA 120. Additionally, Annex B of NFPA 17A will be added to NFPA 120. Additional Proposed Changes File Name DBrohmer_ docx LVS_Brochure_F pdf LVS_Data_Sheet_F pdf Description Approved Statement of Problem and Substantiation for Public Input Wet Chemical Fire Suppressions are now the {(State of The Art) for Vehicle Fire Suppression Systems}. This is not only for Ansul LVS Liquid Vehicle Systems which is what we use for vehicle fire suppression who we are a large manufacture of vehicle fire suppression systems for vehicle protection but competitive manufactures such as Amerex as well have gone to Wet Chemical Vehicle Fire Suppressions and Amerex is also present as a Committee Members on NFPA Standard 120 & 122. I am confident they will look forward to the change proposed. I am not saying to eliminate Dry Chemical Fire Suppression Systems. All hazard analysis conducted on every vehicle requiring protection now are wet chemical only. We no longer suggest, recommend or quote dry chemical fire suppression systems for vehicle fire protection. The only exception is with the Twin Agent Requirement for Large Hydraulic Excavators which is already called out in our 120 & 122 Standards and that will remain. Attached is a Data/Specification Sheet as well as a Wet Chemical Brochure for additional support in understanding the features & benefits of wet chemical systems in preventing re-flash & re-ignition of a vehicle involved in a fire. The usage of wet agent within vehicle suppression technology is quite significant. Through countless hours of testing and various outside 3rd party approvals, we have determined that the most reliable and most beneficial way to put out, and keep out fires, is to use a wet agent. This type of agent will not only effectively suppress fire, but in the vehicle world, will cool any superheated surfaces such as turbochargers and manifolds; typically the main ignition source for vehicle fires. We found that by cooling these components under auto-ignition temperatures of hydraulic and diesel fuels, the ability to re-flash after the end of a chemical discharge becomes minimal.

Annex A Explanatory Material Annex 1l is not a part of the requirements of this NFPA document bul is included for informational purposes only. This annex contains explanation, numbered to correspond with the applicable text paragraphs. A.1.1 The wet chemical systems described in this standard are designed to discharge wet chemical from fixed nozzles and Hose by means of expellant gas. The intent of the standard is to present the design considerations applicable to these systems. The wet chemicals produced by va1ious manufacturers usually are not identical in all characteristics, and each manufacturer designs equipment for use with a specific wet chemical. Therefore, system design principles applicable to the products of one manufacturer are not applicable to the products of another manufacture1: As a result, it is not practical to include system design details as part of this standard. However, such system design details are an integral part of the listing of the systems and are included in the manufacturers' design, installation, and maintenance manuals. A.1.3 See Annex B for recommendations for installation of vehicle fire suppression system applications. 201f Edition A See IEEE/ASTM SI 10, American National Standard for Metric Practice. A.1.7 Although training and qualification might be available elsewhere, it is recommended that such training and qualification be performed by the manufacturer of the equipment being installed or serviced or by the manufacturer's agent. It might be necessary for many of those charged with the purchasing, inspecting, testing, approving, operating, and maintaining of this equipment to consult an experienced fire protection engineer competent in this field, in order to discharge their duties effectively. 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 Lo 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 indi-vidual such as a fire chief; fire marshal; chief of a fire prevention bureau, labor department, or health department; building official; electrical inspector; or ot11ers 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 prope1 ty owner or his or her designated agent assumes the role of the authority having jurisdiction; at government installations, the commanding officer or depart- mental 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 Inspection. This is done by verifying that the system is in place, that it has not been activated or tampered with, and that there is no obvious physical damage or condition to prevent operation. A Manufacturer's Design, Installation, and Maintenance Manual. It contains a description of the hazards that can be protected as well as the limitations of the wet chemical extinguishing system. This manual also requires that the wet chemical extinguishing system be designed, installed, inspected, maintained, and serviced in accordance with NFPA l7a. A Operating Devices. Operating devices include "actuating devices," which initiate operation (automatic detection devices or systems), and manual pulls or strike buttons

20 ANNEX A That respond to the actuation (release mechanisms, shutoff devices, alarms, and auxiliary equipment). A Pre-Engineered Systems. Pre-Engineered systems should be listed by a testing laboratory. The maximum and minimum pipe lengths and the number of fittings should be permitted to be expressed in equivalent feet (meters) of pipe. The hazards protected by these systems should be limited as to type and size based on actual fire tests. Limitations on hazards that are permitted to be protected by these systems are contained in the manufacturer's design, installation, and maintenance manual, which is part of the listing of the system. A Wet Chemical. The terms liquid agent and wet agent are used interchangeably with wet chemical, A.4.2 Fixed temperature-sensing element brackets should be installed so that the brackets do not shield the detector from the heat of the cooking appliances. A Stamping part numbers into the body of the nozzle is an acceptable method of meeting the identification requirement. A Pre-engineered systems do not need calculations for flow rate, pressure drop, and nozzle pressure, since they have been tested for fire extinguishment with minimum and maximum piping limitations and minimum and maximum temperature limitations. These limitations have been verified by testing laboratories and are published in the manufacturer's design, installation, and maintenance manual. Therefore, it is not necessary for a professional engineer or architect to seal the design of 1ese systems. or A Pipe and fittings should be installed in accordance with good commercial practices. Care should be taken to avoid possible restrictions due to foreign matter, faulty fabrication, or improper installation. The following is considered a good practice: The solution's effect on fires in form a vapor suppression foam that floats on a liquid surface, effectively preventing re-ignition of the fire. Extinguishing Mechanisms. Wet chemical solution applied to flammable liquid surfaces results in the rapid spreading of a vaporsuppressing foam on the fuel surface. The foam extinguishes and secures the flame by forming a barrier between the liquid fuel and oxygen. This barrier excludes oxygen from the fuel source and eliminates the release of flammable vapors from the fuel surface. The cooling effect of this solution also lowers the temperature of the flammable fuel, further decreasing fuel vapor release. CAUTION: Wet chemical, when discharged, is in the form of a fine spray. Some of the agent can settle on surrounding surfaces and can have a corrosive effect on electrical components and cooking equipment. Prompt cleanup will minimize staining or corrosion. A.4.9.l Contaminants and foreign materials can affect the extinguishing agent distribution due to a reduction in the effective nozzle orifice area. t,>e. /l)..s / ( q - rf l'f t )rr/(j rc-.jj t o. 1 /j_o'(-/.u-.

(2) Once hose is assembled and prior to nozzle installation, the entire hose system should be blown out with nitrogen or dry air. (3) The hose is should be securely supported and should not be subject to mechanical, chemical, or other damage. (4) All piping should be installed in pipe hanger or brackets and fastened to rigid surfaces. (5) All hose mounting brackets, hangers, and support fixtures should be installed in a manner that ensures nozzles are properly aligned and that prevents nozzles from being (6) moved out of alignment. A union should be installed between the extinguishing agent storage container and the supply line. A A wet chemical solution generally includes, but is not limited to, a potassium carbonate-based, potassium acetatebased, potassium citrate-based solution or a combination thereof and is mixed with water to form an alkaline solution capable of being discharged through piping or tubing when under expellant gas pressure. 201 Edition

21 11Wz --- WET CHEMICAL EXTINGUISHING SYSTEMS A.6.1 One of the first steps in the design and installation of a Fire extinguishing system should be to maintain complete and accurate records. Establishment of a job file will provide a means of documentation. A job file should contain all drawings, sketches, checklists, notes, maintenance agreements and 2019 Edition correspondence related to the installation om start to finish. Photographs are encouraged and should include a wide shot that shows the location of all in the protected area at the time of installation. The photographs, as well as any checklists, drawings, or sketches, should be signed and dated. A.6.2 Manufacturers of fire suppression system equipment should make available the manufach1re1 's design, installation, and maintenance manual and product safety bulletins to the authority having jurisdiction upon request. A The test is intended to verify that flow is continuous and that the piping and nozzles are reasonably unobstructed. The nitrogen or dry air should be introduced into the piping network at the extinguishing agent container connection using a test cylinder or other suitable source. The quantity of nitrogen or dry air used for this test should be sufficient to verify that each nozzle is unobstructed. Nozzle flow should be verified at each discharge nozzle. A Figure A is an example of an acceptance test report. A A reasonable program for qualification of service technicians is for an individual to pass a written or online examination. The Lest should contain a reasonable number of questions Lo challenge the individual's knowledge of the subject matter. A It is recommended that system maintenance personnel be certified as outlined in It is standard industry practice to provide expiration dates on certificates. A Regular service contracts are recommended.

23 ' Vl'ET CHEMICAL EXTINGUISHING SYSTEMS A (3) The following methods can be used la verify that piping is not obstructed: (1) Disassembly of all-hose & pipe (2) Conducting a full or partial discharge test (3) Utilizing other methods recommended by the manufacturer A The hydrostatic testing of wet chemical containers should follow the applicable procedures outlined in Section 7.5. A A discharge of the wet chemical normally is not part of this test. A Under special circumstances or when local requirements are in effect, additional infom1ation can be desirable or required. A Fixed temperature-sensing element are manufactured to operate at predetermined temperatures, causing the system to discharge. Fixed temperature sensing elements are typically listed with the temperature ratings shown in Table A It is important to select fixed temperature-sensing elements that respond in a timely manner during a fire but that do not result in an unwanted discharge. It is also important to periodically take a temperature reading at each installation location Lo ensure the replacement devices arc appropriate for each location. Improper selection of replacement devices could result in an unwanted discharge or a delayed response. A.7.4.l Wet chemical solutions normally have no lasting significant effects on the skin, respiratory system, or clothing. They can produce mild temporary skin irritation after prolonged skin exposure, but symptoms usually disappear when contact is eliminated. Irritation of the eyes should be treated by flushing with tap water for 15 minutes or longer. Any condition of prolonged irritation should be referred to a physician for treatment. Table A Typical Temperature Ratings of Fixed Temperature-Sensing Elements Temperature Maximum Ambient Temperature Temperature Rating Class F c F c Low Ordinary Intermediate High Extra high Very extra high Ultra high Treatment of skin irritation due to exposure to wet chemical is best handled by flushing with water. These systems investigated to determine that they do not splash burning when installed in accordance with the manufacturer's design, installation, and maintenance manual. It is known that e is moderately irritating to the skin and eyes and t at repeated skin contact can lead to dermatitis, but t11is is based on concentrations higher than those used in wet chemical extinguishing system units. A The characteristics of the system are dependent on the composition of the wet chemical solution and the type of expellant gas, as well as other factors; therefore, i t is imperative to use the wet chemical provided by the manufacturer of the system and the type of expellant gas specified by the manufacturer of the system. Systems are designed on the basis of the flow and extinguishing characteristics of a specific formulation of wet chemical. Storage of wet chemical solution in containers other than those supplied by the manufacturer can result in agent contamination 01 deterioration and confusion regarding its identity. A.7.5 DOT- or TC-marked cylinders can be required to be subjected to more frequent testing. A DOT- or TC-marked containers installed in a system not under the jurisdiction of DOT or TC arc not required to follow DOT or TC requirements as long as they remain in operation. Annex B Vehicle Fire Suppression Systems This annex is not a part of the requirements of this NF PA document but is ij1clttded for informational purposes only. B.1 Only pre-engineered wet chemical systems, including detection systems that have been listed for such use, should be used for vehicle fire suppression systems and should not include cooking appliances inside the vehicle. B.2 Compartments or areas that could be subject to fire should be protected in accordance with the manufacturer's design, installation, and maintenance manual. B.3 Each protected compartment or area should be provided with a listed fire detection device specified in the manufacturer's design, installation, and maintenance manual to automatically actuate the extinguishing system. B.4 Manna! Actuation should be permitted to be provided only if acceptable Lo the authority having jurisdiction. B.5 Only the flexible hose and hose fittings specified in the manufacturer's design, installation, and maintenance manual should be used. B.6 All discharge nozzles should be located to minimize the likelihood of damage or mis-alignment and within the limita-tions and constraints of the manufacturer's design, installation, and maintenance manual. B.7 Location of agent containers, expellant gas cartridges or cylinders, and a manual actuator station(s) should be appropriate to each application, protected against physical damage, and accessible Editlon
