Statement of Problem and Substantiation for Public Comment This public comment does not extract language from NFPA 90A but simply makes the requirements identical. Note that CSA FT6 is not referenced in NFPA 90A because it has not kept up with the advances incorporated into NFPA 90A. Standards Council has stated that NFPA 90A has jurisdiction over the requirements for materials in plenums.

Statement of Problem and Substantiation for Public Comment This public comment simply slightly revises the requirements by incorporating language that corresponds to the language from NFPA 90A, which has jurisdiction over materials in plenums, in accordance with Standards Council. The reference to the CSA standard is being removed because it has not kept up to date with the changes in NFPA standards.

26 Public Comment No. 16-NFPA [ Section No ] Cable routing assemblies shall be listed to the requirements of UL Statement of Problem and Substantiation for Public Comment Both the NEC and NFPA 90A (which has jurisdiction over materials in plenums) do not allow cable routing assemblies to be used in plenums unless tested by the default criteria. Cable routing assemblies can be used in trays and risers but not in plenums unless tested as any other material in a plenum. UL 2024 uses a less severe fire test that ASTM E84 (25/50), the default test, and NFPA 90A has rejected its use for cable routing assemblies. I am a committee member of NFPA 90A. This public comment introduces the requirements from NFPA 90A for materials in plenums. The requirements for noncombustible or low flame spread and smoke based on testing to ASTM E84 are those that apply to all materials and products not otherwise mentioned with specific requirements. An alternate public comment adds the specific requirements for all default materials (including cable routing assemblies) in plenums, per NFPA 90A.

30 12 of 35 1/12/2015 3:00 PM Public Comment No. 5-NFPA [ Section No ] * Removal or Storage of Combustibles. Combustibles shall not be removed from stored in telecommunications equipment areas or shall be stored appropriately areas except in protected storage rooms, noncombustible enclosed storage cabinets or bins, noncombustible covered refuse containers, or listed self-extinguishing-type trash receptacles. Statement of Problem and Substantiation for Public Comment The Technical Committee clarified that the removal of combustibles was addressing telecommunications equipment areas, but they deleted the frequency of removal, which was confusing.

31 13 of 35 1/12/2015 3:00 PM Public Comment No. 7-NFPA [ Section No ] 9.1.4* Heat-Producing Appliances. The use of portable heat-producing appliances shall not be located permitted in any telecommunications equipment area, computer room, individual office areas, individual office cubicles, storage areas, or shipping areas. Statement of Problem and Substantiation for Public Comment Computer rooms, individual office areas, individual office cubicles, storage areas, or shipping areas are not unique to telecommunications facilities. This Standard should only address fire hazards unique to the telecommunications equipment occupancy. More general hazards are already addressed in other NFPA standards. Requirements regarding heat producing appliances in other areas belong in NFPA , which provides general fire protection requirements. There are unintended restrictions in which exceed the requirements of NFPA 1 for no discernible reason in telecommunications equipment areas. An example of an unintended restriction is a heat-producing tool such as a soldering iron or heat shrink device.

34 Public Comment No. 9-NFPA [ Section No. 9.6 ] 9.6 * Physical Security A key box(es), where required by the authority having jurisdiction, shall be listed and installed in an accessible location The operator of the premises shall immediately notify the authority having jurisdiction and provide the new key(s) when a lock shall be changed or re-keyed, and a key(s) to that lock shall be contained in the key box. Statement of Problem and Substantiation for Public Comment Key boxes are not unique to telecommunications facilities. The requirements in NFPA 1 specifically address the use of key boxes in more detail than do those in Section 9.6. NFPA 76 should only address fire hazards unique to the telecommunications equipment occupancy. More general hazards are already addressed in other NFPA standards. NFPA 1 is the fundamental document that provides general fire protection requirements. It is the definitive standard and should be the only one that contains general requirements. Repeating requirements already in NFPA 1 leads to confusion and conflicting enforcement when requirements of one document diverge from the other, which occurs because they are not on the same revision cycle. NFPA 76 was a stand-alone document that is now a Standard referenced in NFPA 1, the primary governing document for general fire prevention.

39 Public Comment No. 13-NFPA [ Section No ] 9.11 * Vacant Areas. Vacant areas or spaces in a building shall be reviewed annually for the fire risk. Statement of Problem and Substantiation for Public Comment The term vacant areas or spaces is ambiguous. Is a space vacant when it is no longer being used, but contains retired-in-place equipment? Vacant spaces are not unique to telecommunications facilities. All facilities are vulnerable to the hazards of combustible material stored in vacant spaces. However if those spaces contain stored material, they are not vacant and therefore not covered by Section If the space is truly vacant (i.e., clean and empty floor to ceiling and wall to wall) then there are no additional fire protection measures necessary. The risk is already minimized. In addition, the requirement is vague. It gives no guidance as to what an annual review for the fire risk consists of and what should be done with any findings.

42 A The temperatures in hot aisles can exceed 37.8 C (100 F), which is often the listing limit on many types of detectors. 24 of 35 1/12/2015 3:00 PM

43 25 of 35 1/12/2015 3:00 PM A Smoke Detector Sensitivity and Spacing Guidance for Protection of Signal Processing Equipment in High Airflow Areas General For smoke detections systems to detect products of combustion, the products must travel from the source to a sensor or port and arrive there in sufficient density to be detectable. Products of combustion follow forced air streams early in the development of a fire, or overheat condition, when the influence of mechanical systems is greater than the buoyant forces of the fire or overheat condition. Detection system sensors or ports installed in the paths of cooling air exhaust from the cooled equipment can be expected to respond to a small fire in the equipment sooner than sensors or ports located outside of the ventilation air envelope. To be effective, the detection equipment installed within the ventilation air envelope should be suitable for the temperatures, air velocities and other conditions present. If suitable detection equipment cannot be installed within the exhaust ventilation air envelope, a fire in the cooled equipment should be expected to grow to a size at which its energy is sufficient to overcome the mechanical forces of the HVAC containment system. In the presence of aisle containment systems used to enhance the effectiveness of cooling signal processing equipment, sensors or ports located in hot aisles or in the above ceiling plenum may be effective. Regardless, sensors or ports located on the ceiling in signal processing equipment areas are a basic requirement and contribute to effective detection over a broad range of signal processing equipment area configurations. Listed signal processing equipment has inherent fire resistant characteristics. Failing or overheated components or connections may lead to smoldering events that produce smoke but tend to remain small due to the very low electrical voltages present at the board level in the signal processing equipment. Exceptions may occur when a source of energy external to the signal processing equipment drives increasing involvement of the materials present. In such exceptional cases, flaming fires may result. Automatic fire and smoke detection systems installed to detect smoldering events and/or flaming fires in signal processing equipment areas are more effective in detecting flaming fires than smoldering events due to the respective release rates of combustion products and the effects of forced air flow on the products of combustion. The greater the air flow, which dilutes and channels detectable products of combustion, the less effective will be the performance of the detection system. Damage or losses that may result from smoldering events or flaming fires in signal processing equipment prior to detection are likely to be greater in the presence of greater forced air flow due to the likely decrease in detection system performance. Smoke Detection Systems for Very Early Warning Where a smoke detection system is installed for the primary purpose of summoning responsible people to the presence of a small signal processing equipment fire, or electrical event that produces smoke, the system should be arranged with high sensitivity and close spacing to achieve response to low density products of combustion suspended in air with reasonable stability and tolerance of the environment. Smoke Detection Systems to Initiate Operation of HVAC Dampers or to Close Openings in Fire Rated Walls Where smoke a smoke detection system is installed for the primary purpose of initiating operation of dampers, shutters, doors or other closures in the event of a fire in an SIGNAL PROCESSING EQUIPMENT area, the system should be arranged with medium sensitivity and spacing less than listed spacing to assure the integrity of fire resistive barriers. Smoke Detection Systems to Initiate Release of a Fire Suppression Agent Where smoke a smoke detection system is installed for the primary purpose of initiating the release of a fire suppression agent into an SIGNAL PROCESSING EQUIPMENT Area, the system should be arranged with low sensitivity, spacing less than listed spacing, and should include a form of logical confirmation of the presence of products of combustion to assure that a single indication does not release the agent..
