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. This public comment does not incorporate any material or products that are not already referenced in NFPA 76.

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.

8.8.2.8.3 Cable routing assemblies shall be listed to the requirements of UL 2024.
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.

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. We believe the Technical Committee intends that combustibles not be stored in these areas. This revision clarifies the provision and gets to the heart of the matter.

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 1-11.5.3, which provides general fire protection requirements. There are unintended restrictions in 9.1.4 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.

9.6 * Physical Security.9.6.1
A key box(es), where required by the authority having jurisdiction, shall be listed and installed in an accessible location.9.6.2
The operator of the premises shall immediately notify the authority having jurisdiction and provide the new key(s) when a lock shall be changedor 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.

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 9.11. 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.

A.8.2.3.6 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 insufficient 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 mechanicalsystems is greater than the buoyant forces of the fire or overheat condition. Detection system sensors or ports installed in the paths of coolingair exhaust from the cooled equipment can be expected to respond to a small fire in the equipment sooner than sensors or ports located outsideof the ventilation air envelope. To be effective, the detection equipment installed within the ventilation air envelope should be suitable for thetemperatures, air velocities and other conditions present. If suitable detection equipment cannot be installed within the exhaust ventilation airenvelope, a fire in the cooled equipment should be expected to grow to a size at which its energy is sufficient to overcome the mechanicalforces of the HVAC containment system.
In the presence of aisle containment systems used to enhance the effectiveness of cooling signal processing equipment, sensors or portslocated 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 effectivedetection 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 tosmoldering events that produce smoke but tend to remain small due to the very low electrical voltages present at the board level in the signalprocessing equipment. Exceptions may occur when a source of energy external to the signal processing equipment drives increasinginvolvement 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 aremore effective in detecting flaming fires than smoldering events due to the respective release rates of combustion products and the effects offorced air flow on the products of combustion. The greater the air flow, which dilutes and channels detectable products of combustion, the lesseffective will be the performance of the detection system. Damage or losses that may result from smoldering events or flaming fires in signalprocessing equipment prior to detection are likely to be greater in the presence of greater forced air flow due to the likely decrease in detectionsystem 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 signalprocessing equipment fire, or electrical event that produces smoke, the system should be arranged with high sensitivity and close spacing toachieve 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 closuresin the event of a fire in an SIGNAL PROCESSING EQUIPMENT area, the system should be arranged with medium sensitivity and spacing lessthan 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 SIGNALPROCESSING EQUIPMENT Area, the system should be arranged with low sensitivity, spacing less than listed spacing, and should include aform of logical confirmation of the presence of products of combustion to assure that a single indication does not release the agent. .
Sensitivity and Spacing Ranges

25 of 35 1/12/2015 3:00 PM
(1) Smoke sensor and port spacing on ceilings in the presence of high air movement should follow the requirements of NFPA 72 section17.7.6.3.
(2) Where air changes per hour (ACH) in the room served by the ventilation system exceeds 60, and where the supply air is delivered to theroom through a raised floor, smoke sensors or ports under the floor may not be effective in detecting a fire originating under the floor. Theymay, however, be effective in detecting a fire originating in an air handling unit supplying air to the underfloor space.
(3) For sensors and ports installed in the exhaust/return air stream in hot aisles or above ceiling plenums, the spacing and sensitivities listed inTable A.8.2.3.6 should be used. The guidance in Table A.8.2.3.6 comes partly from a study sponsored by the Fire Protection ResearchFoundation. That guidance is conservative since it is based on testing using airflow without recirculation into the volume being studied.
(4) In applying the sensor or port spacing, it is recommended that sensors and ports be located at strategic points where smoke is likely topass; for example, in hot air return streams and at return air registers.

Public Comment No. 22-NFPA 76-2014 [ Section No. A.8.8.3 ]
A.8.8.3 UL 60950-1 specifies the fire resistance performance of the materials used in making the equipment and therefore provides a level ofprotection. However, UL 60950 does not require fire safety performance testing of the final equipment configuration as Telcordia-GR-63-COREdoes, and does not provide assurances that the fire will not continue to propagate past a single piece of equipment as required by GR-63.
Statement of Problem and Substantiation for Public Comment
Fire resistance is defined as a property assessing the ability of a material, product, or assembly to withstand fire or give protection from it for a period of time. Thissection addresses fire performance requirements.

Annex G Fire Detection for IT Area Risks and Special Conditions G.1 Introduction
For fire detection systems to be effective in signal processing areas, the design and installation must respond to the special conditions and unusual risks present. The requirements in NFPA 72 for fire detection systems might not provide effective early detection of fires in IT areas. This standard permits equivalent solutions (see Section 1.5) to achieve its purpose (see Section 1.2). The standard recognizes the performance-based approach to determine equivalent solutions (see
Chapter 5). The standard permits design of fire detection systems based on a fire risk assessment (see
Chapter 4). These fire risk assessments consider the risk of specified losses and need to consider the likelihood of fires (ignition source and fuel ignited by location in the protected space) and the likely response of the selected detector(s) in the proposed location(s). A 2013 paper by Bukowski discusses the most likely fires that might occur in data centers based on limited fire experience reported by a major, global operator as part of committee task group activities. G.2 Risk Assessment Objective(s)
The objective of a fire risk assessment is to minimize risk by mitigating the consequences of a fire or reducing its likelihood. Life safety (preventing fatalities and reducing or eliminating injuries) is generally the prime objective of a fire risk assessment, but modern data centers operate with relatively few staff located mostly in the ancillary areas. Technicians venture into the signal processing) areas only when necessary to install and service equipment. Life safety risk in the ancillary areas is similar to office occupancies, and the life safety risk in the equipment areas is very low; there are few occupants, and fires are rare and grow very slowly. The widespread practice of data mirroring greatly reduces the risk of data loss. Thus the primary objective of data center fire protection is to mitigate the likelihood of loss of capacity to process, store and retrieve data. G.3 Design Fire Scenarios
Fire experience in data centers shows that by far, the most common fires involve ancillary fuels in adjacent spaces such as meeting rooms, offices, and break rooms. The inclusion of fire and smoke barriers between these spaces and the signal processing spaces, along with sprinklers and detectors as usually provided in office occupancies, will prevent fires in these spaces from affecting signal processing. Additionally, strict enforcement of housekeeping rules for signal processing areas so that there are no (even temporary) accumulations of combustibles (e.g., packaging materials, construction materials, or papers/manuals) limits the risk of fires in ancillary areas affecting signal processing. The most common fire sources within the signal processing areas most frequently involve power supplies, including UPSs, because these contain some combustible materials, which can produce significant fault energies, and involve components that run hot since they are operated near rated capacity for maximum electrical efficiency. Physical separation of power supply equipment and associated power cables from digital equipment and data cables and the inclusion of overheat sensors to shut down power supplies exceeding normal operating conditions can minimize fire risk to the facility
from such equipment. The next most common fire scenarios involve HVAC or other support equipment located within signal processing areas. The most likely fires originating in cooling equipment involve (combustible) filters and overheating fan motors. Wire and cable fires are limited to power cables; these are the only cables that contain significant fault energy and can run warm enough to permit combustion of the insulation or jacket materials. Most wire and cable insulation and jacketing will not support combustion unless heated internally or externally. Physical separation or specific protection such as enclosed cable trays and linear overheat detection can result in adequate mitigation. The least common fires are in the signal processing itself, particularly where that equipment is listed to UL 60950, Safety of Information Technology Equipment, or Telcordia GR-63-CORE, Network Equipment Building System (NEBS)™ Requirements: Physical Protection, standards.
