Underwriters Laboratories Inc., 333 Pfingsten Road, Northbrook, IL 60062. UL 300, Fire Testing of Fire Extinguishing Systems for Protection of Restaurant Commercial Cooking Areas Equipment, 1996 edition 2005. Substantiation: Update title and edition of referenced standard. Add ANSI/ to the reference Committee Statement: Editorial. 17A-2 Log #8 Final Action: Accept in Principle (Chapter 3) Submitter: J. R. Nerat, Badger Fire Protection Recommendation: Add new and modify definitions as follows: INSPECTION is the periodic monthly visual quick check of a system intended to determine that the protected hazard has not changed and that there are no equipment conditions present that would dictate the need for an immediate maintenance examination by a properly trained person. MAINTENANCE is the thorough periodic semi-annual examination of a system to ensure the hazard is properly protected and that all system equipment and components will operate effectively and safely in accordance with the recommendations contained within the systems listed maintenance manual. SERVICE includes the installation, maintenance, recharge and hydrostatic testing of system hardware and related equipment. TRAINED PERSON is one who has undergone the instruction necessary to safely design, install, service, maintain, recharge and hydrostatically test system equipment in accordance with the equipments, listed installation and maintenance manual. Substantiation: The proposed definitions more clearly identify and address the existing system equipment requirements associated with these standards. Do not accept the revisions to Inspection or Maintenance or Trained Person Revise the definition of Service using the definition from NFPA 10 as follows: Servicing - Performing maintenance, recharging, or hydrostatic testing. Committee Statement: Service and Maintenance are sometimes used interchangeably. This definition connects the two. See also Committee Proposal 17A-3 (Log #CP2) for work on other definitions. 17A-3 Log #CP2 Final Action: Accept (Chapter 3) Submitter: Technical Committee on Dry and Wet Chemical Extinguishing Systems, Recommendation: Add a definition for Certified Person and revise the definition for Trained as follows: Certified Person One who is trained, and holds a current certificate from the equipment manufacturer or a recognized organization, verifying that the holder has completed a formal certification program and has demonstrated a satisfactory level of competency that is acceptable to the AHJ. Trained One who has undergone the instruction necessary to safely design, install and reliably perform the maintenance and recharge service in accordance with the manufacturer s listed manual. Substantiation: Clarification of these terms for the purpose of processing requirements within the standard. This revision addresses certification of the individual and brings this standard into line with the proposals to NFPA 96. 17A-4 Log #CP1 Final Action: Accept (Chapter 3 Definitions (GOT)) Submitter: Technical Committee on Dry and Wet Chemical Extinguishing Systems, Recommendation: Adopt the following definitions from the NFPA Glossary of Terms for the following terms: Maintenance. (preferred) Boilerplate: NFPA 10, 2002 ed. Work performed to ensure that equipment operates as directed by the manufacturer Modify the definition of pipe as follows: Pipe. (secondary) NFPA 17-2002 ed. Circular conduit for conveying the dry chemical extinguishing agent to the discharge nozzle(s). Wherever pipe is used in this standard, it shall be understood also to mean tube. Substantiation: Adoption of preferred definitions will assist the user by providing consistent meaning of defined terms throughout the National Fire Codes. 17A-5 Log #9 Final Action: Accept in Principle (3.3.x Certified Person (New) ) Recommendation: Add a new definition to read: Certified Person. A person that has been certified by a recognized organization through a formal certification program or by an equipment manufacturer that has a certification program, that is acceptable to the authority having jurisdiction. Substantiation: Fire extinguishing system manufacturers certify the company not the individual. This revision addresses certification of the individual and brings NFPA 17 in line with the current ROP of NFPA 96. See Committee Action on Proposal 17A-3 (Log #CP2). Committee Statement: Committee Proposal 17A -3 (Log #CP2) addresses this definition. 17A-6 Log #39 Final Action: Reject (3.3.21 Electronic Pressure Monitoring (New) ) Submitter: John J. McSheffrey, Jr., MIJA, Inc. Recommendation: Add a new definition to read: 3.3.21 Electronic Pressure Monitoring. A method of electronic communication (data transmission) between an in-place fire extinguishing system and an electronic monitoring device/system. Substantiation: Electronic pressure monitoring technology for fixed systems provides continual monitoring of a system s operating pressure ensuring that a system is fully pressurized if needed. With many systems installed in hard to reach locations, monthly inspections to ensure that the pressure gauge is in the operable range can be laborious and as a result many times ignored. By electronically monitoring the pressure gauge, systems owners can ensure that their systems are working by simply checking the monitoring device/system. The technology is UL listed and is similar to the technology currently recognized in NFPA-10 and NFPA-72. Please refer to the datasheet for additional information. Note: Supporting material is available for review at NFPA Headquarters. Committee Statement: These devices along with other indicators, are addressed in the definitions of auxiliary equipment and indicators, and therefore no additional text is necessary. 17A-2
17A-7 Log #23 Final Action: Reject (4.4.3.6 (New) ) Recommendation: Add new text to read: 4.4.3.6 On activation of any cooking equipment fire-extinguishing system, the makeup air supplied internally to a hood shall be shut-off. Renumber the existing 4.4.3.6 to 4.4.3.7 and renumber 4.4.3.7 to 4.4.3.8. Substantiation: This added language is consistent with NFPA 96, 8.3.2. Committee Statement: Not in the scope of. NFPA 96 addresses this. 17A-8 Log #3 Final Action: Reject (4.4.3.8 (New) ) Submitter: James Everitt, Western Regional Fire Code Development Committee Recommendation: Add a new section to read: 4.4.3.8 All shutoff valves or switches shall be plainly visible. Substantiation: Inspectors need to be able to see these devices when performing inspection. Users need to be able to easily find them so that they can reset these systems. Far too often, these devices are hidden above ceilings and behind equipment. This change would make it clear that they need to be visible and accessible. Committee Statement: Users should not be resetting shut-off devices. End users should not be resetting these devices. This should be done by a qualified individual. 17A-9 Log #7 Final Action: Accept in Principle (5.1) Submitter: Bob Eugene, Underwriters Laboratories Inc. 5.1 General. 5.1.1 Wet chemical fire-extinguishing systems shall comply with standard UL 300, Fire Testing of Fire Extinguishing Systems for Protection of Restaurant Commercial Cooking Areas Equipment. Substantiation: Update title of referenced standard. Add ANSI/ to UL reference. Committee Statement: Editorial. 17A-10 Log #24 Final Action: Accept (5.3.1 (New) ) Recommendation: Add new text to read: 5.3.1 Where electrical power is required to operate the fixed automatic fireextinguishing system, it shall be monitored by a supervisory alarm with a reserve power supply provided. Substantiation: The existing 5.3.1 will remain, but renumbered. This requirement comes from NFPA 17, 9.6.1. If electrical activation means are utilized, the system must have some form of system supervision or redundant mechanical detection. The current 5.3.1 addresses supervision. But only when provided. If electrical, it must be provided. 17A-11 Log #25 Final Action: Accept (5.3.1.1) Recommendation: 5.3.1.1 (Same as existing 5.3.1 except renumbered). Substantiation: The language in existing 5.3.1 will remain but renumbered as 5.3.1.1. 17A-12 Log #26 Final Action: Accept (5.3.1.2) Recommendation: 5.3.1.2 (Same as existing 5.3.2 except renumbered). Substantiation: The language in existing 5.3.2 will remain but renumbered as 5.3.1.2. 17A-13 Log #27 Final Action: Accept (5.3.2 (New) ) Recommendation: Add new text to read: 5.3.2 Where fixed automatic fire-extinguishing systems include automatic mechanical detection and actuation as a backup detection system, electrical power monitoring and a reserve power supply is not required. Substantiation: The existing 5.3.2 will remain, but renumbered. This requirement comes from current NFPA 17, 9.6.2, with the addition of a reserve power supply. If electrical activation means are utilized, and the system can also be activated by mechanical detection and actuation, electrical supervision of the detection circuit, and a reserve power supply is not required. This addition is consistent with NFPA 96, 10.7.2. 17A-14 Log #28 Final Action: Accept (5.3.3 (New) ) Recommendation: Add new text to read: 5.3.3 Where fixed automatic fire-extinguishing systems are interconnected or interlocked with the cooking equipment power sources so that if the fire-extinguishing system becomes inoperable due to power failure, all sources of fuel and heat to all cooking appliances serviced by that hood shall automatically shutoff, electrical power monitoring is not required. Substantiation: This added language is consistent with NFPA 17, 9.6.3. 17A-15 Log #10 Final Action: Accept (5.4.6) Recommendation: Wet chemical containers and expellant gas assemblies shall be located near the hazard or hazards protected per manufacturer s limitations but not where they will be exposed to the fire. Substantiation: Near the hazard is too vague and can be subject to various interpretations. The important limitation is that the containers be located within the guidelines specified by the manufacturer s listing. 17A-16 Log #11 Final Action: Accept in Principle (5.5.1 & 5.5.2) Recommendation: Revise text as follows: 5.5.1 All discharge nozzles shall be designed and subsequently located, installed, or protected so that they are not subject to mechanical, environmental, or other conditions that could render them inoperative. 5.5.2 Discharge nozzles shall be connected and supported. 5.5.1 All discharge nozzles shall be located so as to minimize the likelihood of damage or misalignment and be within the limitations and constraints of the manufacturer s listed installation and maintenance manual. Substantiation: Adds the requirement that the nozzle placement be in accordance with the guidelines specified by the manufacturer s listing. 17A-3
Revise proposed language as follows: 5.5.1 All discharge nozzles shall be located to minimize damage or misalignment and be within the limitations and constraints of the manufacturer s listed installation and maintenance manual. Committee Statement: Clarification of the requirement. 17A-17 Log #29 Final Action: Accept (5.6.2.1.1) 5.6.2.1.1 A fusible link or other mechanically operated heat detection device, from the common duct fire extinguishing system, heat detector shall be located at each branch duct-to-common duct connection, when electrical operation of the common duct fire extinguishing system does not meet the requirements of 5.3.1. Substantiation: Unless there is a pollution control unit or other similar device installed within the common ductwork, a fire in the common duct will have resulted from a fire originating in an appliance under a protected ventilator that the common duct is servicing. Fires resulting from pollution control units and the like, will have additional detection. The intent of the detector at the connection from the branch duct to the common duct is intended as a safety backup for a system that may be actuated electrically without circuit monitoring capabilities and/or secondary power. When the common duct fire extinguishing system includes a control panel in accordance with NFPA 72, National Fire Alarm Code (e.g., circuit monitoring and reserve power supply), redundant mechanical detection is not needed. In addition, the redundant detection device must operate without electrical power. 17A-18 Log #30 Final Action: Accept (5.6.2.1.2) Recommendation: Delete the following text: 5.6.2.1.2 Actuation of any branch duct to common exhaust duct fusible link or heat detector shall actuate the common duct system only, or when all independent systems are detonated to a control panel in accordance with NFPA 72, National Fire Alarm Code. Substantiation: With revision to 5.6.2.1.1. This requirement is not needed. In addition, the current language is somewhat confusing. 17A-19 Log #31 Final Action: Accept (5.6.2.1.2) 5.6.2.1.2 Actuation of any branch duct to common exhaust duct fusible link or heat detector shall actuate the common duct system only, or when all independent systems are connected to a control panel in accordance NFPA 72, National Fire Alarm Code. Where a fusible link or mechanically operated heat detector is located at a branch duct-to-common duct connection, an access panel shall be installed, in accordance with NFPA 96, Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, to enable servicing of the detector, when the detector is not accessible from the branch duct connection to the exhaust hood. Substantiation: Fusible link detectors must be replaced semiannually and need to be accessible. Unless the detector can be accessed through the branch duct connection to the exhaust hood, an access panel will need to be installed in accordance with NFPA 96. 17A-20 Log #12 Final Action: Reject (5.6.4) Recommendation: Delete the following text: 5.6.4 Movable cooking equipment shall be provided with a means to ensure that it is correctly positioned in relation to the appliance discharge nozzle during cooking operations. Substantiation: This is the responsibility of NFPA 96. Committee Statement: Redundancy in the two standards is important and it is in the scope of operation of the extinguishing system. 17A-21 Log #4 Final Action: Accept (6.2) Submitter: Jon Nisja, Northcentral Regional Fire Code Development Committee Recommendation: Revise to read: 6.2* Review and Certification. Design and installation of systems shall be performed only by persons properly trained and qualified to design and/or install the specific system being provided. The installer shall provide certification to the authority having jurisdiction that the installation complies is in complete agreement with the terms of the listing and the manufacturer s instructions and/or approved design. Substantiation: Complies is better wording than the existing text. 17A-22 Log #13 Final Action: Accept (6.4.2) Recommendation: Delete the following text: 6.4.2 The installer shall certify that the system has been installed in accordance with the approved plans and the manufacturer s listed installation and maintenance manual. Substantiation: This requirement is already addressed in Section 6.2. 17A-23 Log #5 Final Action: Reject (6.4.3) Submitter: Jon Nisja, Northcentral Regional Fire Code Development Committee Recommendation: Revise to read: 6.4.3 Where required by the authority having jurisdiction, the approval tests shall include a discharge of wet chemical to verify that the system is properly installed and functional. 6.4.3.1* As an alternative to discharging of wet chemical, the piping shall be pneumatically tested in a closed circuit for a period of 10 minutes at 40 psig (276 kpa). At the end of 10 minutes, the pressure drop shall not exceed 20 percent of the test pressure. 6.4.4* A flow test using nitrogen or an inert gas shall be performed on the piping network to verify that flow is continuous and that the piping and nozzles are unobstructed. 6.4.5 The owner shall be provided with a copy of the manufacturer s listed installation and maintenance manual or listed owner s manual. Substantiation: The language was taken from NFPA 2001 Standard on Clean Agent Fire Extinguishing Systems. We have some systems during the puff test or other testing that has leaks. The hydro provision is used in other systems to ensure system integrity. Committee Statement: This proposal is based on a gaseous versus a liquid medium and is not appropriate for this extinguishing system. Ballot Results: Affirmative: 11 Negative: 1 Explanation of Negative: KASISKI, R.: The substantiation provided for rejection is not technically correct. Clean agents such as NOVEC 1230 are in liquid state during discharge where the technique in this proposal may be used. Also, the Committee has Accepted 17A-24 (Log #14). If the manufacturer s listed manual identifies this technique, it would not preclude its usage. 17A-4
17A-24 Log #14 Final Action: Accept (6.4.3) Recommendation: Revise text to read as follows: 6.4.3* Where required by the authority having jurisdiction, the approval tests shall include a discharge of wet chemical test, in accordance with the manufacturer s listed installation manual, to verify that the system is properly installed and functional. Substantiation: The current annex sections states that the discharge test should be in accordance with the system manufacturer s manual and the test agents used should be as recommended by the system manufacturer. This change eliminates the mandatory use of wet chemical for system discharge testing if the system manufacturer allows the use other test agents. 17A-25 Log #15 Final Action: Accept in Principle (7.2.3) Recommendation: Revise text to read as follows: 7.2.3 If any deficiencies are found When an inspection reveals a deficiency in any of the conditions listed in 7.2.2, appropriate corrective action shall be taken immediately. Any required maintenance shall be performed by a trained and certified individual. Substantiation: This revision adds specific reference to the inspection verification list and enforces the requirement that individuals performing system maintenance should be certified and trained. This change is similar to a requirement in the current NFPA 96 ROP. Change certified individual to certified person Committee Statement: Proposal 17A-3 (Log #CP2) changed this term. 17A-26 Log #2 Final Action: Accept in Principle (7.3.1) Submitter: Robert Bourke, Northeastern Regional Fire Code Dev. Recommendation: Revise to read: 7.3.1 A trained person who has a valid manufacturer s training certificate shall service the wet chemical fire-extinguishing system at intervals not more than 6 months apart as outlined in Section 7.3.2. Substantiation: The proposed wording better clarifies what training is required for the individual to perform service on systems. See Committee Action on Proposal 17A-27 (Log #16). Committee Statement: Proposal 17A-27 (Log #16) addresses this requirement. 17A-27 Log #16 Final Action: Accept (7.3.1) Recommendation: Add text to read as follows: 7.3.1* A trained and certified person who has undergone the instructions necessary to perform the maintenance and recharge service reliably and has the applicable manufacturer s listed installation and maintenance manual and service bulletins shall service the wet chemical fire-extinguishing system at intervals no more than 6 months apart as outlined in 7.3.2. Substantiation: Individuals performing system maintenance should be certified and trained. This revision also makes the six months a maximum period and allows maintenance at intervals less than six months apart. This requirement is similar to the current NFPA 96 ROP. 17A-28 Log #17 Final Action: Accept in Principle (7.3.2.4.1 and 7.3.2.4.2) Recommendation: Add text to read as follows: 7.3.2.4.1 Until such repairs are accomplished, the systems shall be tagged non-compliant and the owner, designated party responsible for the system, and the authority having jurisdiction shall be notified of the impairment. 7.3.2.4.2 When all repairs have been accomplished and the system has been restored to the full and operating conditions all previously notified parties shall be informed that the system is in the full and operating condition. Substantiation: The current edition of the standard does not address notification of system impairment. This is standard industry practice and the addition of these new sections will make such notification mandatory. Revise proposal as follows: 7.3.2.4.1 Until such repairs are accomplished, the systems shall be tagged noncompliant and the owner or owner s representative responsible for the system, and the authority having jurisdiction shall be notified of the impairment. 7.3.2.4.2 When all repairs have been accomplished and the system has been restored to the full and operating conditions all previously notified parties shall be informed that the system is in the full and operating condition. Committee Statement: Correlates with new language in NFPA 17. 17A-29 Log #18 Final Action: Accept in Principle (7.3.2.5) Recommendation: Add text to read as follows: 7.3.2.5 The maintenance report, with recommendations, if any, shall be filed with the owner or with the designated party responsible for the system and shall be retained for a period of three years. Substantiation: This revision adds a limitation on how long maintenance records need to be maintained by the owner. Revise as follows: 7.3.2.5 The maintenance report, including any recommendations, shall be filed with the owner or with the owner s representative. 7.3.2.5.1 The owner or owner s representative shall retain all maintenance reports for a period of one year after the next maintenance of that type required by the standard. Committee Statement: Clarifies that the owner or representative is to obtain and retain the maintenance records, and provides a more realistic time for retaining the records. Correlates with requirements in NFPA 17. 17A-30 Log #19 Final Action: Reject (7.3.2.5.1) Recommendation: Add text to read as follows: 7.3.2.5.1 Where required, certificates of inspection and maintenance shall be forwarded to the authority having jurisdiction. Substantiation: Many jurisdictions require copies of inspection and maintenance reports. When required, this revision allows for these reports to be filed with the AHJ. Committee Statement: The AHJ will determine if all reports are required to be submitted. 17A-31 Log #20 Final Action: Accept in Principle (7.3.3) Recommendation: Revise text to read as follows: 7.3.3* Fixed temperature-sensing elements of the fusible metal alloy type shall be replaced at least semi-annually from the date of installation. They shall be destroyed when removed. Substantiation: This revision coordinates the requirements of, NFPA 96, and manufacturer s requirements. 17A-5
See Committee Action on Proposal 17A-32 (Log #32). Committee Statement: Committee Action on Proposal 17A-32 (Log #32) addresses this issue. Ballot Results: Affirmative: 11 Negative: 1 Explanation of Negative: KASISKI, R.: No data was submitted to substantiate the benefit of mandating the replacement interval for fixed temperature-sensing elements of the fusible metal alloy type from the current maximum one year interval to a maximum semi-annual interval. Also, the current requirement does not inhibit more frequent intervals if necessary. 17A-32 Log #32 Final Action: Accept (7.3.3) 7.3.3 Fixed temperature-sensing elements of the fusible metal alloy type shall be replaced at least semiannually from the date of installation, or more frequently, if necessary. annually from the date of installation. They shall be destroyed when removed. Substantiation: Fusible link detectors must be replaced semiannually as a minimum, per the link manufacturer. NFPA 96 also requires a semiannual replacement (NFPA 96, 11.2.4). Ballot Results: Affirmative: 11 Negative: 1 Explanation of Negative: KASISKI, R.: No data from the manufacturer of fixed temperature-sensing elements of the fusible metal alloy type was submitted to substantiate the benefit of mandating the replacement interval for fixed temperature-sensing elements of the fusible metal alloy type from the current maximum one year interval to a maximum semi-annual interval. Also, the current requirement does not inhibit more frequent intervals if necessary. 17A-33 Log #33 Final Action: Accept (7.3.4) 7.3.4 Fixed temperature sensing elements Heat detectors, other than the fusible metal alloy type fusible links, shall be permitted to remain continuously in service, provided they are inspected and, cleaned and tested, or replaced if necessary, in accordance with NFPA 72 and the manufacturer s instructions every 12 months or more frequently to ensure proper operation of the system at least semi-annually or sooner depending on operating conditions. Substantiation: The current 7.3.4. requirement does not include testing the detectors. NFPA 72 should be referred to for the service of the various types of thermal detection, and should be followed, along with the requirement to service the detectors semi-annually, as opposed to the current, 7.3.4 annual requirement. In addition, the current language in 7.3.4 somewhat conflicts with 7.3.2 and 7.3.2.1(2). 7.3.2 states that At least semiannually, maintenance shall be conducted... Then in 7.3.2.1 it states that, Maintenance shall include the following: (2) An examination of all detectors,.... Ballot Results: Affirmative: 11 Negative: 1 Explanation of Negative: KASISKI, R.: No data was submitted to substantiate the benefit of mandating the inspection, testing and cleaning interval of detectors from the current maximum one year interval to a maximum semi-annual interval. Also, the current requirement does not inhibit more frequent intervals if necessary. 17A-34 Log #34 Final Action: Accept (7.3.4.1 (New) ) Recommendation: Add a new section to read: 7.3.4.1 As a minimum, inspection and testing for restorable type heat detectors shall include the following: (1) A visual inspection to determine that there is no damage to the detector or buildup of foreign debris. (2) An operational/functional test in accordance with the detector manufacturer s testing instructions. (3) A calibration verification test if applicable, in accordance with the detector manufacturer s instructions. Substantiation: The requirements above are taken from NFPA 72, and need to be included here as guidelines for servicing restorable heat detectors. 17A-35 Log #35 Final Action: Accept in Principle (7.3.4.2 (New) ) Recommendation: Add a new section to read: 7.3.4.2 Non-restorable heat detectors shall be functionally tested mechanically and electrically, if applicable, without heat applied. Substantiation: Non-restorable heat detection cannot be tested with heat, due to the one shot operational characteristics of the detection device. However, mechanical testing of the fire suppression system, with detection system simulation, must be performed to ensure mechanical automatic operation. In addition, there may be electrical tests that can be performed on certain electrically operated non-restorable models. Revise proposed language as follows: 7.3.4.2 Non-restorable heat detectors shall be functionally tested in accordance with the manufacturer s recommendations. Committee Statement: Clarification of the testing procedures. Correlates with requirements in NFPA 17. 17A-36 Log #36 Final Action: Accept in Principle (7.3.4.3 (New) ) Recommendation: Add a new section to read: 7.3.4.3 Heat detectors and all associated wiring, that have been subjected to direct flame impingement, exhibit scorch marks, or show signs of damage due to excessive temperatures or other means, shall be replaced. Substantiation: A heat detection device is the first line alarm initiating device, warning personnel and activating the fire-extinguishing system. For personnel safety, it is of utmost importance that they be warned of such a condition and the fire be suppressed, as quickly as possible. Detectors that may be damaged, either due to a high heat condition, or by other means, must be replaced. If a potential condition exists that cannot be determined by testing methods, it is only prudent to replace the detector(s), as opposed to allowing a false sense of security. Revise the proposal as follows: 7.3.4.3 Heat detectors and all associated wiring that show signs of fire damage shall be tested in accordance with the manufacturer s recommendations and replaced if necessary. Committee Statement: Clarifies the requirements and establishes the manufacturer s recommendations as the primary source of test criteria. Correlates with requirements in NFPA 17. 17A-6
17A-37 Log #21 Final Action: Accept (7.4.3) Recommendation: Add text to read as follows: 7.4.3 After any discharge the system piping shall be flushed in accordance with the procedures detailed in the manufacturer s listed installation and maintenance manual. Substantiation: Restates the requirement of section 7.1.4(3) in the section pertaining to Recharging. 7.4. 17A-38 Log #1 Final Action: Reject (10.6.1.1.2) Submitter: Marion Long, National Fire Information Council Recommendation: Add:, Standard for Wet Chemical ExtinAguishing Systems to the list of standards in 10.6.1.1.2. Revise code 6 to read: Clean agent systems including Halogen type system. Revise code 8 in 10.6.1.1.3 to read: Wet Chemical Extinguishing Systems. Revise code 0 in 10.6.1.1.3 to read: O. Type of automatic extinguishing system not able to classify further. Included are water spray systems, explosion suppression systems, steam smothering systems, chemical foam systems, and systems dispensing dry powder for metal fires. Substantiation: Wet chemical systems are increasingly being used to provide fire suppression for cooking equipment in restaurants and commercial kitchens. The data element Type of Automatic Extinguishing System does not currently address these systems. The NFIC Systems Committee feels it is more important to have a code number for wet chemical systems than water spray systems. NFIRS has included water spray systems in the not able to be classified further together with the other suppression systems that the fire service seldom encounters. Committee Statement: Not in. 17A-39 Log #38 Final Action: Accept in Principle (11.2.1.1(6)) Submitter: John J. McSheffrey, Jr., MIJA, Inc. 11.2 Owner s Inspection. 11.2.1 On a monthly basis, inspection shall be conducted in accordance with the manufacturer s listed installation and maintenance manual or owner s manual. 11.2.1.1 As a minimum, this quick check or inspection shall include verification of the following: (1) The extinguishing system is in its proper location. (2) The manual actuators are unobstructed. (3) The tamper indicators and seals are intact. (4) The maintenance tag or certificate is in place. (5) The system shows no physical damage or condition that might prevent operation. (6) The pressure gauge(s), if provided, may be inspected physically or electronically to ensure it is in the operable range. (7) The nozzle blowoff caps, where provided, are intact and undamaged. (8) Neither the protected equipment nor the hazard has been replaced, modified, or relocated. Substantiation: Electronic pressure monitoring technology for fixed systems provides continual monitoring of a system s operating pressure ensuring that a system is fully pressurized if needed. With many systems installed in hard to reach locations, monthly inspections to ensure that the pressure gauge is in the operable range can be laborious and as a result many times ignored. By electronically monitoring the pressure gauge, systems owners can ensure that their systems are working by simply checking the monitoring device/system. The technology is UL listed and is similar to the technology currently recognized in NFPA 10 and NFPA 72. Please refer to the datasheet for additional information. Note: Supporting material is available for review at NFPA Headquarters. Change may to shall. Change numbering to 7.2.2 Committee Statement: Editorial. Correlates with requirements in NFPA 17. 17A-40 Log #37 Final Action: Reject (A.3.3.21) Submitter: John J. McSheffrey, Jr., MIJA, Inc. Recommendation: Add new annex material to read: A.3.3.21 Electronic Pressure Monitoring. Electronic monitoring can be accomplished utilizing low-voltage wiring or a wireless communication method, and can convey information about an in-place fire extinguishing system that includes status, pressure level and early indication of a system discharge. Electronic monitoring can satisfy the monthly inspection requirements for pressure currently within the standard and can create an electronically maintained record of the fire extinguishing system.

Sequence of Events Leading to Issuance of an NFPA Committee Document Step 1 Call for Proposals Proposed new Document or new edition of an existing Document is entered into one of two yearly revision cycles, and a Call for Proposals is published. Step 2 Report on Proposals (ROP) Committee meets to act on Proposals, to develop its own Proposals, and to prepare its Report. Committee votes by written ballot on Proposals. If two-thirds approve, Report goes forward. Lacking two-thirds approval, Report returns to Committee. Step 3 Report on Proposals (ROP) is published for public review and comment. Report on Comments (ROC) Committee meets to act on Public Comments to develop its own Comments, and to prepare its report. Committee votes by written ballot on Comments. If two-thirds approve, Reports goes forward. Lacking two-thirds approval, Report returns to Committee. Step 4 Report on Comments (ROC) is published for public review. Technical Committee Report Session Notices of intent to make a motion are filed, are reviewed, and valid motions are certified for presentation at the Technical Committee Report Session. ( Consent Documents that have no certified motions bypass the Technical Committee Report Session and proceed to the Standards Council for issuance.) NFPA membership meets each June at the Annual Meeting Technical Committee Report Session and acts on Technical Committee Reports (ROP and ROC) for Documents with certified amending motions. Step 5 Committee(s) vote on any amendments to Report approved at NFPA Annual Membership Meeting. Standards Council Issuance Notification of intent to file an appeal to the Standards Council on Association action must be filed within 20 days of the NFPA Annual Membership Meeting. Standards Council decides, based on all evidence, whether or not to issue Document or to take other action, including hearing any appeals. viii
The Technical Committee Report Session of the NFPA Annual Meeting The process of public input and review does not end with the publication of the ROP and ROC. Following the completion of the Proposal and Comment periods, there is yet a further opportunity for debate and discussion through the Technical Committee Report Sessions that take place at the NFPA Annual Meeting. The Technical Committee Report Session provides an opportunity for the final Technical Committee Report (i.e., the ROP and ROC) on each proposed new or revised code or standard to be presented to the NFPA membership for the debate and consideration of motions to amend the Report. The specific rules for the types of motions that can be made and who can make them are set forth in NFPA s rules, which should always be consulted by those wishing to bring an issue before the membership at a Technical Committee Report Session. The following presents some of the main features of how a Report is handled. What Amending Motions Are Allowed. The Technical Committee Reports contain many Proposals and Comments that the Technical Committee has rejected or revised in whole or in part. Actions of the Technical Committee published in the ROP may also eventually be rejected or revised by the Technical Committee during the development of its ROC. The motions allowed by NFPA rules provide the opportunity to propose amendments to the text of a proposed code or standard based on these published Proposals, Comments, and Committee actions. Thus, the list of allowable motions include motions to accept Proposals and Comments in whole or in part as submitted or as modified by a Technical Committee action. Motions are also available to reject an accepted Comment in whole or part. In addition, motions can be made to return an entire Technical Committee Report or a portion of the Report to the Technical Committee for further study. The NFPA Annual Meeting, also known as the World Safety Conference and Exposition, takes place in June of each year. A second Fall membership meeting was discontinued in 2004, so the NFPA Technical Committee Report Session now runs once each year at the Annual Meeting in June. Who Can Make Amending Motions. Those authorized to make these motions are also regulated by NFPA rules. In many cases, the maker of the motion is limited by NFPA rules to the original submitter of the Proposal or Comment or his or her duly authorized representative. In other cases, such as a Motion to Reject an accepted Comment, or to Return a Technical Committee Report or a portion of a Technical Committee Report for Further Study, anyone can make these motions. For a complete explanation, NFPA rules should be consulted. The Filing of a Notice of Intent to Make a Motion. Before making an allowable motion at a Technical Committee Report Session, the intended maker of the motion must file, in advance of the session, and within the published deadline, a Notice of Intent to Make a Motion. A Motions Committee appointed by the Standards Council then reviews all notices and certifies all amending motions that are proper. The Motions Committee can also, in consultation with the makers of the motions, clarify the intent of the motions and, in certain circumstances, combine motions that are dependent on each other together so that they can be made in one single motion. A Motions Committee report is then made available in advance of the meeting listing all certified motions. Only these Certified Amending Motions, together with certain allowable Follow-Up Motions (that is, motions that have become necessary as a result of previous successful amending motions) will be allowed at the Technical Committee Report Session. Consent Documents. Often there are codes and standards up for consideration by the membership that will be noncontroversial, and no proper Notices of Intent to Make a Motion will be filed. These Consent Documents will bypass the Technical Committee Report Session and head straight to the Standards Council for issuance. The remaining Documents are then forwarded to the Technical Committee Report Session for consideration of the NFPA membership. ix
Action on Motions at the Technical Committee Report Session. In order to actually make a Certified Amending Motion at the Technical Committee Report Session, the maker of the motion must sign in at least an hour before the session begins. In this way, a final list of motions can be set in advance of the session. At the session, each proposed Document up for consideration is presented by a motion to adopt the Technical Committee Report on the Document. Following each such motion, the presiding officer in charge of the session opens the floor to motions on the Document from the final list of Certified Amending Motions followed by any permissible Follow-Up Motions. Debate and voting on each motion proceeds in accordance with NFPA rules. NFPA membership is not required in order to make or speak to a motion, but voting is limited to NFPA members who have joined at least 180 days prior to the session and have registered for the meeting. At the close of debate on each motion, voting takes place, and the motion requires a majority vote to carry. In order to amend a Technical Committee Report, successful amending motions must be confirmed by the responsible Technical Committee, which conducts a written ballot on all successful amending motions following the meeting and prior to the Document being forwarded to the Standards Council for issuance. Standards Council Issuance One of the primary responsibilities of the NFPA Standards Council, as the overseer of the NFPA codes and standards development process, is to act as the official issuer of all NFPA codes and standards. When it convenes to issue NFPA documents it also hears any appeals related to the Document. Appeals are an important part of assuring that all NFPA rules have been followed and that due process and fairness have been upheld throughout the codes and standards development process. The Council considers appeals both in writing and through the conduct of hearings at which all interested parties can participate. It decides appeals based on the entire record of the process as well as all submissions on the appeal. After deciding all appeals related to a Document before it, the Council, if appropriate, proceeds to issue the Document as an official NFPA code or standard, recommended practice or guide. Subject only to limited review by the NFPA Board of Directors, the decision of the Standards Council is final, and the new NFPA document becomes effective twenty days after Standards Council issuance. The illustration on page 9 provides an overview of the entire process, which takes approximately two full years to complete. x
