There are two criteria necessary for each first revision to pa ss ballot: (1) simple majority and (2) affirmative 2 /3 vote. The mock examples below show how the calculations are determined. (1) Example for Simple Majority: Assuming there are 20 vote eligible committee members, 11 affirmative votes are required to pass ballot. (Sample calculation: 20 members eligible to vote 2 = = 11) (2) Example for Affirmative 2 /3: Assuming there are 20 vote eligible committee members and 1 member did not return their ballot and 2 members abstained, the number of affirmative votes required would be 12. (Sample calculation: 20 members eligible to vote 1 not returned 2 abstentions = 17 x 0.66 = = 12 ) As always please feel free to contact me if you have any questions.

25 4 of 181 2/24/ :27 PM First Revision No. 7-NFPA [ Section No ] * Fire Heat Release Rate for Ventilation Calculations. Rate of energy release for a given fire scenario or fire test, expressed as a function of time[w (Btu/s)]. Submitter Information Verification Submitter Full Name: Chad Duffy Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Mon Nov 17 10:57:08 EST 2014 Committee Statement Committee Statement: The concept of heat release rate is the same whether it is used for a fire test or a fire modeling project. Typically small scale fire tests, such as ASTM E1354, cone calorimeter, require measurements of heat release rate per unit area and large scale fire tests or fire modeling require absolute measurements, in W or BTU/s. The term is being renamed "fire heat release rate" to make it unique to NFPA 130, since no other NFPA document has that term. The add-on "for ventilation calculations" is unnecessary as it limits the concept. Watts was changed to kilowatts for consistancy.

Sandu, Julian Thomas, Michael J. Till, Robert C. White, Steven C. Wilchek, Stephen B. Zicherman, Joseph B. Affirmative with Comment Locke, Harold A. This change in terminology should be reconciled with the use of 'heat release rate' elsewhere in the text (e.g., Chapter 5). Also, the sub-definitions are not used in the text and should therefore be deleted or moved to an Annex if they are used there.

52 9 of 181 2/24/ :27 PM Zip: Submittal Date: Tue Nov 18 07:42:16 EST 2014 Committee Statement Committee Statement: This is simply clarification because the section somehow became garbled. The logic is the following. 1. The first possible classification is the use of noncombustible materials as interior wall and ceiling finish materials. 2. The other options are, first testing to NFPA 286 (room-corner fire test) and any material is allowed to be tested to this test. 3. The requirements for being acceptable when testing to NFPA 286 are those indicated next. 4. Most materials (except for the list of 4 in the next section) are allowed to be fire tested to ASTM E84 instead of testing to NFPA 286 (Steiner tunnel test). 5. Four materials are not safe when simply tested to ASTM E84 and they need to be tested to NFPA 286 always. 6. In the exclusive case of foam plastic insulation, it is important to make it clear that placing a textile or vinyl facing is not a way to "allow" it to be used without testing to NFPA 286. The other materials are never covered by facings because they have an attractive finish. 7. The new section is being added so there is no longer any need to describe materials individually.

Locke, Harold A. Per comments received during the first ballot that indicated potential misinterpretation and in keeping with the move towards performance or objective based criteria, revise the proposed first revision to Section and Annex A to read as follows: For stations where the concourse is protected from exposure to the effects of a train fire at the platform, that concourse shall be permitted to be defined as a point of safety. A The determination of whether the concourse is protected from exposure to a train fire will be dependent on station configuration. For aboveground stations, factors to be considered may include distance, geometry or fire separation. For enclosed stations equipped with emergency ventilation in accordance with Chapter 7, engineering analysis will be necessary to confirm adequate protection. The use of point of safety in this context is intended to imply that the design of the station egress routes permits continued egress from the concourse to the exterior of the station. Negative with Comment Laurin, Pierre The proposed change is interpreted to mean that distance, geometry, fire separation or a fire ventilation system, with no confirmation by engineering analysis, are sufficient to define a concourse as a point of safety. Unless a station meets the definition of an Open Station, an engineering analysis shall be required, particularly if the concourse is not below platform level. For enclosed stations, the engineering analysis needs to confirm that the ventilation system provides protection. 2 of 181 2/24/ :27 PM

Currently the Standard provides no guidance for such an arrangement and leaves the AHJ with little code backing to require research or substantiation for such a project. This proposal is simply a place to start the committee s input on green track installations. This section does not seek to specifically allow or prohibit such installation, however it will give the AHJ the authority to make informed, educated decisions on its use based upon a reasonable risk assessment.

In fact it is common to see preservativetreated wood used for rail ties everywhere. Therefore the NFPA 130 standard should be clear that there are three levels of fire performance required: (a) enclosed locations, (b) switch and crossover locations and (c) all other locations. In switch and crossover locations there is a need for added fire test requirements because of the potential for ignition via sparks at these locations. It has been shown that wood (or plastic lumber) materials with added fire performance can be developed and such materials will help address the added fire safety problem. Rail ties outdoors do not have a fire safety issue and can be made of wood or of plastic lumber materials provided the plastic lumber materials meet the recent specification that requires the added 7 of 181 2/24/ :27 PM

74 8 of 181 2/24/ :27 PM structural properties, that was developed by ASTM for that purpose (ASTM D7568). The fire performance of the plastic lumber materials that meet ASTM D7568 is required to be the same as that of wood materials: 200 flame spread index in ASTM E84. It has also been shown that plastic lumber materials that comply with ASTM D7568 have structural performance that is at least as good as that of wood materials. They are widely used by the US army for rail ties in areas (such as bridges) where tanks cross, as is the case in Fort Bragg, for example. Some web sites showing the plastic materials in use follow: railroad-crossties The proposed language would require that both the wood and plastic lumber materials used at switch and crossover locations have to exhibit a better than normal flame spread index (75 or Class B) instead of 200 or Class C as is normally required. It was also clarified that wood should be pressure treated wood.

The dictionary's definition, "Door, Entrance or the approach or entrance to a bridge or tunnel" does not convey the intent of the paragraph which is to prevent the passage of smoke and heat to an adjacent tunnel segment and to provide a point of safety for evacuating passengers. Tunnel segments 200 feet and under could be separated by a few feet thus not requiring an engineering analysis or mechanical ventilation system. Smoke could travel throughout the tunnel segments and create an untenable environment throughout the egress route and still be in compliance with the current NFPA 130. Requiring a 15m(50ft) opening between tunnel and station segments will insure that smoke will not create an untenable environment in a segment adjacent to the segment where the fire occurred. This is especially important where open cut trackways have been covered to create tunnel and station segments, and the openings or portals between segments do not contain an egress to the surface.

Roman, Steven W. Sandu, Julian Thomas, Michael J. Till, Robert C. White, Steven C. Wilchek, Stephen B. Zicherman, Joseph B. Negative with Comment Alston, Jarrod The practice of assuming one fan out of service or unavailable speaks to system reliability and availability. Alternative means exist for addressing risks and hazards associated with equipment availability including redundancy, maintenance and testing to reduce MTBF, or increased system-wide capacity as would be called for by assuming fans out of service. Design criteria should instead simply call for consideration of system availability. Devlin, John F. This standard requires many features be incorporated into the mechanical emergency ventilation system's design for the purpose of ensuring operational availability and reliability. If the committee believes that the current edition of the standard does not provide reasonable guidance and safeguards for "the loss of a fan" then I believe a special task group should be formed to analyze this matter and return to the committee a detailed analysis assessment, findings, and recommendations for improvement.

Negative with Comment Zicherman, Joseph B. I appreciate the addition of the corresponding appendix section, the proposed text for the standard does not address the nuanced differences between potential ignition sources that have been treated by installation with a barrier separating them from passenger spaces (battery boxes, power conditioning equipment, distribution equipment) and the separate class of equipment which - if there were a fire occurring - would indeed by intimate with passengers and crew. This class includes items such as ovens, information displays, coffee makers, point off sale equipment and other items. These need to be addressed specifically for the reasons stated in the original proposal. 3 of 181 2/24/ :27 PM

103 A On-board energized electrical equipment not subject to regulation in other sections of this standard should be subject to a fire safety analysis.

The performance criteria should be included in the Table in to make it consistent with the location of all the materials performance criteria. Therefore "batter case material" was added to the "Other Vehicle Components" category. The performance criteria will be deleted from Chapter (7) in a subsequent proposal. In the 2014 draft copy of NFPA 130 Chapter 8 (ref. ROP ) the smoke emission requirements for the adhesives and sealants was correct. However in the final printing of the 2014 version, the change was executed incorrectly, eliminating the performance criteria for Optical Density at 1.5 minutes. This proposed change corrects that error. NFPA 251 was withdrawn and therefore the reference needs to be removed.

Historically the roofs have been tested inverted on the traditional furnace. When tested inverted their is no room in the furnace to add suspended equipment loads as they would interfere with the location of the thermocouples which are essential in regulating the time/temperature curve dictated by ASTM E119. Recent roof tests that have been tested in the upright position do include the equipment load on the roof as the burners are located between the equipment boxes and the roof skin. Unfortunately not all the traditional test laboratories are set up to conduct the roof test in the upright position.

122 08 of 181 2/24/ :27 PM First Revision No. 22-NFPA [ Section No ] The minimum fire exposure duration shall be the greater greatest of the following: (1) (2) * Twice the maximum expected time period under normal circumstances for a vehicle to stop completely and safely from its maximum operating speed, plus the time necessary to evacuate a full load of passengers from the vehicle under approved conditions * 15 minutes for automated guideway transit (AGT) vehicles and low floor vehicles, 30 minutes for all other passenger-carrying vehicles (3) 15 minutes for roof assemblies Submitter Information Verification Submitter Full Name: Chad Duffy Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Mon Nov 17 17:39:51 EST 2014 Committee Statement Committee A recent popular class of rail vehicles are streetcars which operate solely on the streets in mixed Statement: traffic. They do not operate in tunnels or on overhead guideways. The typical streetcar is a low floor design which forces all equipment to the roof of the vehicle. Therfore there is very little combustible material beneath the floor. The typical streecar also has three doorways per side (some longer vehicles may have more) which provide many avenues of escape in case of an emergency evacuation, requiring only one step down to the street level. Currently there is a large emphasis placed on weight reduction in modern rail vehicles due to the sensitivity in this industry to reduced energy consuption. Requiring a 30 minute floor design does increase the weight of the vehicle. With three doors per side evacuation times will be very low considering that passengers will not have to use a ladder to evacuate to the road bed as they would on a rapid transit, commuter, intercity and some light rail lines. In order to facilitate a light weight design reducing the floor fire test time to 15 minutes for streetcars is appropriate. Without a specified exposure time for testing roof assemblies, the current intepretation of NFPA 130 leads the exposure time for roof assemblies to be 30 minutes. The traditional method of testing the roof assemblies is inverted on the ASTM E119 furnace. This type of exposure (directly down the roof) with the heat of the E119 furnace will not be seen in a roof fire. If equipment on a roof is burning, the flames travel way from the roof of a railcar not directly on the roof sheet. Testing of a roof assembly inverted is extremely severe and the carbuilder must include non-traditional insulation materials (rock wool, ceramic fiber insulation) and possibly added insulation on the ceiling panels in order to meet the temperature rise requirements of this Standard. This causes not only an increase in weight of the vehicle but also an increase in cost. Testing on an ASTM E119 furnace for a time of 15 minutes is more than adequate for a roof assembly.

Supplemental Information File Name New_Chapter_10.docx Description Submitter Information Verification Submitter Full Name: Chad Duffy Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Mon Nov 24 15:04:50 EST 2014 Committee Statement Committee See attached "Word Document" for "New Chapter 10". Statement: To the credit of the Technical Committee, NFPA 130 has for many years contained requirements for a variety of communication system types, long before the inclusion of specific and prescriptive design, installation, commissioning, inspection, testing and maintenance requirements found their way into NFPA 72 National Fire Alarm and Signaling Code. That said, NFPA 72 now contains such requirements, making most if not all of the current text of Chapter 10 of NFPA 130 and portions of Chapter 5 obsolete, or at the very least in conflict with NFPA 72. In some cases, NFPA 130 is either silent or provides little design guidance with respect to some of the types of communications that are required or are regularly found in use in fixed guideway transit and passenger rail system, such as: textual and graphical visible appliances; intelligibility parameters for emergency voice/alarm communications, mass notification, and use of public address systems for emergency communications and/or fire alarm notification; and public safety radio enhancement systems, where again NFPA 72 has an entire chapter dedicated to all of the various communication technologies. In the case of the radio systems, not only does NFPA 72 contain very prescriptive requirements but so does the 2012 International Fire Code (IFC). Chapter 5 of the 2012 IFC would require a radio enhancement system for most enclosed stations despite the requirements in NFPA 130 and would require those systems to comply with the requirements of the IFC, which essentially mirror those of NFPA 72. Most of the proposed changes to Chapter 10 above are offered in an attempt to reconcile the terminology between NFPA 130 and NFPA 72, to eliminate conflicts and to acknowledge that in the area of emergency communication, NFPA 72 is the prevailing code in the same manner in which NFPA 101, NFPA 14, NFPA 13, NFPA 241 and others are recognized as source documents for egress, standpipes, sprinkler systems and construction safety respectively. The elements of Operations Control Center (OCC) and Command Post Relationship that are deleted from Chapter 10 are related to communications procedures and have therefore been relocated to Chapter 9. Chapter 9 requirements related to design of the OCC have been relocated to Chapter 10. Response Message:

White, Steven C. Wilchek, Stephen B. Zicherman, Joseph B. Affirmative with Comment Casselman, David M. I support the overall revision, however in proposed Section , it is important to retain the prior wording from Section , "Alternative location(s) shall be provided in the event the OCC is out of service for any reason and shall be equipped or have equipment readily available to function as required by the authority." When originally developed, the wording of that section was carefully chosen to avoid prescribing an alternative OCC if not required by the authority. In smaller systems, solutions other than an alternative OCC are often used. The preferred alternative may be to shut down the system and operate buses until the OCC is restored, or some fully automated systems can be operated from several regional locations or zones. The additional wording, "OCC" and "primary", in the first line prescribe an alternative OCC as the only solution, which may not be appropriate for the system. Negative with Comment

137 23 of 181 2/24/ :27 PM Devlin, John F. I believe the current requirements in of Chapter 10 provide a reasonable degree of guidance on the scope and installation requirements for emergency communications systems. The proposed change is too prescriptive and does not provide appropriate guidance on the minimum intended performance requirements of the communications systems specified.

151 34 of 181 2/24/ :27 PM First Revision No. 11-NFPA [ Section No. A.4.6 ] A The location and size of a fire can greatly affect the degree of hazard to system occupants. Therefore, the system design must consider specific fire scenarios that could occur. Fire location and size are examples of factors that fire scenarios must consider: (1) Interior locations. This scenario occurs from a fire that originates within a station or trainway or the interior passenger compartment of the vehicle. Examples of interior fire scenarios include the following: (a) (b) (c) (d) (e) (f) (g) Fire that begins from an incendiary ignition involving the use of accelerants Trash fire Electrical fire Fire that occurs in a location used for food preparation Luggage storage area fire Fire that occurs from ignition by small open flame onto bedding in an unoccupied compartment in a vehicle that provides compartments for overnight sleeping Fire that occurs where the vehicle rolls over onto its side and ignition occurs (2) Exterior locations. This scenario occurs as a result of a fire originating outside the passenger compartment of the vehicle and penetrating the exterior of the vehicle. Examples of exterior fire scenarios include the following: (a) (b) (c) Electrical fire in the station, in the trainway, under the vehicle floor, or on the roof that burns through into the passenger compartment or that causes the vehicle to stop between stations Trash fire or other type of station, trainway, or under-vehicle equipment or floor fire Fire that occurs from ignition of a fuel spill adjacent to the station, a trainway, or a vehicle involved in a collision (3) Operating environment. Consequences can increase if a fire occurs when occupants are in the following locations: (a) (b) In a station, trainway, or passenger-carrying vehicle that is in a stationary location and unable to move and where egress or rescue access could be hazardous (e.g., underground trainway or station) In a passenger-carrying vehicle in motion between stations and at the maximum distance from any station, safe refuge, or point of safety Fire scenarios that are appropriate for a particular system vehicle and operating environment could not be applicable to another system vehicle and operating environment.

155 38 of 181 2/24/ :27 PM First Revision No. 17-NFPA [ Section No. A ] A For escalators, contribution to the means of egress capacity can be calculated based on one of the following: (1) The width used to calculate the capacity of stopped escalators should be based on the tread width plus the width permitted for intrusion of handrails per NFPA 101 for a 1000 mm (40 in.) tread width, the width used to determine egress capacity will be 1228 mm (48 in.). (2) Where escalators having a nominal width of 1000 mm (40 in.) will be dedicated for operation in the direction of exit travel at speeds of at least 30 m/min (98 ft/min), such escalators can be permitted to be counted as having a capacity of 75 p/min. This should be considered appropriate only in conjunction with other provisions of this standard, such as the requirement to discount one escalator at each station level. Such escalators should also be connected to emergency power. This suggested speed is consistent with the maximum speed permitted in ASME A17.1/CSA B44, a bi-national standard. The suggested capacity is consistent with research reported in the Elevator World article Escalator Handling Capacity and in Pedestrian Planning and Design, by Fruin. Other codes regulating transit station design permit escalator capacity to be based on operating capacity (e.g., Ontario Building Code, Section 3.13, Rapid Transit Stations, and London Underground Ltd., LUL Station Planning Guidelines, which both permit a capacity of 100 p/min.). Designers are encouraged to research the latest available data. Unpublished research suggests that where the vertical rise exceeds 15 m (50 ft), the capacity and travel speed for stairs should be adjusted downward by approximately 30 percent to account for fatigue. Additionally, the design should provide enlarged landings to allow pedestrians to rest without impeding egress flow.

161 44 of 181 2/24/ :27 PM First Revision No. 32-NFPA [ Section No. A ] A Transition from fixed-block to moving-block (cab-based or communication-based) signaling is being made by many properties to increase train throughputs during rush hour operation. Ventilation zones are fixed elements, and the number of trains allowed in a single zone affects both ventilation plant requirements and the effectiveness of the ventilation response. Traction power blocks are fixed elements and affect the ability to extract non-incident trains from the incident ventilation zone. Signal system track circuits are fixed elements and affect the ability to determine the location of incident and non-incident trains in the incident ventilation zone. Signal system reversing capability and rapidness of executing a reversal in an emergency are key to the effective extraction of non-incident trains. Due to the potential for a valid incident ventilation response to move smoke past (and engulf) a non-incident train, the best protection to passengers is to allow no more than one train in a ventilation zone. Failing that, there should be a viable extraction capability to remove non-incident trains in the same time frame as the activation of the ventilation response. This extraction requires coordination of the three system elements in terms of design and with the train operation plans and emergency response plans with respect to how the trains will be operated and how the designed systems will be used during emergency operation. Non-incident trains should be capable of being located and removed from the incident area before the de-energization of the traction power prevents train movement for an extended period or the operation of the ventilation system in response to the fire incident involves the trains in the incident. Examples of the provisions necessary to accomplish this capability are the inclusion of traction power segmentation zones within ventilation zones and the inclusion of sufficiently short track signal circuit lengths to ensure all trains are accurately located.

The viability of the intended operation plan and emergency response are critical when more than one train is designed to be in a ventilation zone. Such viability can only be achieved when the design and operations planning are integral in the determination of project criteria.

168 51 of 181 2/24/ :27 PM B Heat Effects.

169 52 of 181 2/24/ :27 PM (See also I ) Exposure to heat can lead to life threat in three basic ways: (1) Hyperthermia (2) Body surface burns (3) Respiratory tract burns For use in the modeling of life threat due to heat exposure in fires, it is necessary to consider only two criteria: the threshold of burning of the skin and the exposure at which hyperthermia is sufficient to cause mental deterioration and thereby threaten survival. Note that thermal burns to the respiratory tract from inhalation of air containing less than 10 percent by volume of water vapor do not occur in the absence of burns to the skin or the face; thus, tenability limits with regard to skin burns normally are lower than for burns to the respiratory tract. However, thermal burns to the respiratory tract can occur upon inhalation of air above 60 C (140 F) that is saturated with water vapor. The tenability limit for exposure of skin to radiant heat is approximately kw m -2. Below this incident heat flux level, exposure can be tolerated for 30 minutes or longer without almost indefinitely without significantly affecting the time available for escape. Above this threshold value, the time to burning of skin due to radiant heat decreases rapidly according to Equation B.2.1.1a. where: t = time in minutes q = radiant heat flux (kw/m 2 ) ( [ B.2.1.1a) ] As with toxic gases, an exposed occupant can be considered to accumulate a dose of radiant heat over a period of time. The fraction equivalent dose (FED) of radiant heat accumulated per minute is the reciprocal of tirad. Radiant heat tends to be directional, producing localized heating of particular areas of skin even though the air temperature in contact with other parts of the body might be relatively low. Skin temperature depends on the balance between the rate of heat applied to the skin surface and the removal of heat subcutaneously by the blood. Thus, there is a threshold radiant flux below which significant heating of the skin is prevented but above which rapid heating occurs. Based on the preceding information, it is estimated that the uncertainty associated with the use of Equation B.2.1.1a is ±25 percent. Moreover, an irradiance of 2.5 kw m -2 would correspond to a source surface temperature of approximately 200 C, which is most likely to be exceeded near the fire, where conditions are changing rapidly. Calculation of the time to incapacitation under conditions of exposure to convected heat from air containing less than 10 percent by volume of water vapor can be made using either Equation B.2.1.1b or Equation B.2.1.1c. As with toxic gases, an exposed occupant can be considered to accumulate a dose of convected heat over a period of time. The fraction equivalent dose (FED) of convected heat accumulated per minute is the reciprocal of ticonv. Convected heat accumulated per minute depends on the extent to which an exposed occupant is clothed and the nature of the clothing. For fully clothed subjects, Equation B.2.1.1b is suggested: where: ticonv = time in minutes T = temperature ( C) For unclothed or lightly clothed subjects, it might be more appropriate to use Equation B.2.1.1c: where: ( [ B.2.1.1b) ] ( [ B.2.1.1c) ]

170 ticonv = time in minutes T = temperature ( C) Equations B.2.1.1b and B.2.1.1c are empirical fits to human data. It is estimated that the uncertainty is ±25 percent. Thermal tolerance data for unprotected human skin suggest a limit of about 120 C (248 F) for convected heat, above which there is, within minutes, onset of considerable pain along with the production of burns. Depending on the length of exposure, convective heat below this temperature can also cause hyperthermia. The body of an exposed occupant can be regarded as acquiring a dose of heat over a period of time. A short exposure to a high radiant heat flux or temperature generally is less tolerable than a longer exposure to a lower temperature or heat flux. A methodology based on additive FEDs similar to that used with toxic gases can be applied. Provided that the temperature in the fire is stable or increasing, the total fractional effective dose of heat acquired during an exposure can be calculated using Equation B.2.1.1d: ( [ B.2.1.1d) ] Note 1: In areas within an occupancy where the radiant flux to the skin is under 2.5 kw m -2, the first term in Equation B.2.1.1d is to be set at zero. Note 2: The uncertainty associated with the use of this last equation would be dependent on the uncertainties with the use of the three earlier equations. The time at which the FED accumulated sum exceeds an incapacitating threshold value of 0.3 represents the time available for escape for the chosen radiant and convective heat exposures. As an example, consider the following: (1) Evacuees lightly clothed (2) Zero radiant heat flux (3) Time to FED reduced by 25 percent to allow for uncertainty in Equations B.2.1.1b and B.2.1.1c. (4) Exposure temperature constant (5) FED not to exceed 0.3 Equations B.2.1.1c and B.2.1.1d can be manipulated to provide the following : where: texp = time of exposure (min.) to reach a FED of 0.3 This gives the values in Table B Table B Maximum Exposure Time Exposure Temperature C F Without Incapacitation (min.) of 181 2/24/ :27 PM

Pursur says: the tenability limit for exposure of skin to radiant heat is approximately 2.5 kw/m2, below which exposure can be tolerated for at least several minutes. Note that Purser says several minutes not 30 minutes as is presently in NFPA 130. The revised value 1.7 kw/m2 is published in the SFPE Engineering Guide to Predicting First and Second Degree Skin Burns. To benchmark, the thermal radiation on a hot sunny day is about 1.4 kw/m2. The reference to uncertainty is removed because it is factually not correct. Response Message: Revise Equation B.2.1.1a as shown on attached word document.

176 58 of 181 2/24/ :27 PM Noise levels should be a maximum of 115 dba for a few seconds and a maximum of 92 dba for the remainder of the exposure. Criteria for noise levels should be established for the various situations and potential exposures particular to the environments addressed by this standard. The intent of the recommended criteria is to maintain at least a minimal level of speech intelligibility along emergency evacuation routes. This might require additional noise control measures and acoustical treatment to achieve. Exceptions taken to the recommended noise levels for reasons of cost and feasibility should be as few and as slight as reasonably possible. For example, local area exceptions to the recommended acoustic criteria could be required to be applied for defined limited distances along the evacuation path that are near active noise sources. Other means of providing emergency evacuation guidance using acoustic, nonacoustic or combined methods might be considered. Recommendations for noise criteria for various design scenarios are as follows: (1) In general, noise levels should not exceed the following: (a) (b) During emergency response, the sound pressure level from all active systems measured inside a tunnel along the path of evacuation at any point 5 ft (1.52 m) above the walking surface should not exceed 94 dba L eq low for a period of 1 hour and should at no time exceed 140 dbz peak [ISO 1999, EU Directive 2003/10/EC, and Canada Occupational Safety and Health Regulations, SOR/86-304, Part VII )]. The sound pressure level from all active systems measured where staff would be present for maintenance and testing and where hearing protection is not available should not exceed 85 dba TWA slow for a period of 8 hours and should at no time exceed 140 dbz peak [29 CFR (OSHA)]. (2) Where reliance on unamplified speech is used as part of the emergency response, during emergency response, the sound interference level (SIL) from all active systems measured inside a tunnel along the path of evacuation at any point 5 ft (1.52 m) above the walking surface should not exceed 78 dbz L eq slow over any period of 1 minute, using the arithmetic average of un-weighted sound pressure level in the 500, 1000, 2000 and 4000 Hz octave bands. (3) For intelligible communication between emergency evacuation responders and the public where reliance upon amplified speech is used as part of the emergency response within a station the following applies: (a) (b) (c) During emergency response, the sound pressure level from all active systems measured inside a station along the path of evacuation at any point 5 ft (1.52 m) above the walking surface where a voice communication system is intended to be used should not exceed the higher of 70 dba L eq slow measured over any 1 minute period or 10 db below the measured voice communication system sound pressure level in the octave bands greater than 63 Hz with a steady-state red noise input signal set to the maximum A-weighted setting of the voice communication system (if the voice communication system has an ambient sensing microphone). The speech intelligibility of voice communication systems under the same conditions and for the same spaces should achieve a measured STI of not less than 0.45 (0.65 CIS) and an average STI of not less than 0.5 (0.7 CIS) as per D of NFPA 72. Refer to Annex D of NFPA 72 for further information on speech intelligibility for voice communication systems. The STI criterion is more stringent than the noise level limit and might require additional noise control measures and acoustical treatment to achieve. (4) Where reliance upon amplified speech is used as part of the emergency response within a tunnel, the following applies: (a) (b) (c) Where a voice communication system is intended to be used within a tunnel, during emergency response, the sound pressure level from all active systems measured inside a tunnel along the path of evacuation at any point 5 ft (1.52 m) above the walking surface should not exceed 75 dba L eq slow measured over any period of 1 minute. The speech intelligibility of fixed voice communication systems under the same conditions and for the same spaces should achieve a measured STI of not less than 0.45 (0.65 CIS) and an average STI of not less than 0.5 (0.7 CIS) as per D of NFPA 72. Refer to Annex D of NFPA 72 for further information on speech intelligibility for voice communication systems.

Negative with Comment Alston, Jarrod Although only proposed as Annex language, the implications of the proposed annex material has not been fully vetted in terms of what the design requirements and cost implications are for achieving the proposed sound levels. Further, the intent is for alarm signals to be audible, intelligible, or otherwise comprehended. Alternative means for achieving those ends are likely possible rather than placing limitations on sound generation. The NFPA 72 technical committee ought to be conferred with regarding alarm and notification options in noisy environments. Laurin, Pierre Noise levels currently outlined in B are below the general noise level limits stipulated by ISO 1999, EU directive 2003/10/EC, and Canada Occupational Safety and Health Regulations SOR/ Part VII. Sound levels generated and present in trains, tunnels and stations during normal operation exceed these proposed sound level limits for emergency response conditions. The proposed sound level criteria may not be practically achievable nor necessary during emergency in subway ventilation system emergency mode. 60 of 181 2/24/ :27 PM

179 61 of 181 2/24/ :27 PM First Revision No. 49-NFPA [ Section No. B.2.2 ] B.2.2 Geometric Considerations. Some factors that should be considered in establishing a tenable environment in stations are as follows: (1) The evacuation path requires a height clear of smoke of at least 2 m (6.6 ft). For low-ceiling areas, selection of the modeling method and the criteria to be achieved should address the limitations imposed by ceiling heights below 3 m (9.84 ft). At low-ceiling areas in an evacuation path, beyond the immediate vicinity of a fire, smoke should be excluded to the greatest extent practicable. (2) The application of tenability criteria at the perimeter of a fire is impractical. The zone of tenability should be defined to apply outside a boundary away from the perimeter of the fire. This distance will be dependent on the fire heat release rate, the fire smoke release rate, local geometry, and ventilation and could be as much as 30 m (100 ft). A critical consideration in determining this distance will be how the resultant radiation exposures and smoke layer temperatures affect egress. This consideration should include the specific geometries of each application, such as vehicle length, number of vehicles open to each other, fire location, platform width and configuration, and ventilation system effectiveness, among others, and how those factors interact to support or interfere with access to the means of egress. (3) The beneficial effects of an emergency ventilation system during a fire incident will not become completely available until the system is operated and reaches full capacity. During the time between initiation of a fire incident and the desired ventilation response achieving its full capacity, the smoke can spread into the intended zone of tenability. The ventilation system should have sufficient capacity to counter this pre-ventilation smoke spread. Whenever possible, the design of the space geometry should consider arrangements to minimize the pre-ventilation smoke spread. The overall extent of pre-ventilation smoke spread should also be considered with respect to its potential effect on egress. (4) During the emergency ventilation response, short-term transient events due to step-like changes in geometry can momentarily provide a significant boost to the fire heat and smoke release rates. Examples include vehicle doors opening or the failure of vehicle windows. The ventilation system should have sufficient capacity to counter such short-term transients affecting smoke spread.

I appreciate the intent of the proposed language and the fact that this information would be Annex material however a majority of information provide is based upon the premise of voice intelligibility. Communications with passengers in the tunnel trainway during emergency evacuation can be accomplished by many means beyond voice communication. Many transit systems are in cities where many different languages are spoke (There are more than 50 different languages spoken in New York City). The intent of this standard is to provide guidance on providing minimum requirements for effective communications; this code change proposal places too much emphasis on voice communications when there are many other effective means that could be used in a tunnel environment.

182 64 of 181 2/24/ :27 PM C.1.4 Side-Platform Station Sample Calculation.

183 65 of 181 2/24/ :27 PM The sample side-platform station is an enclosed station with a concourse above the platform level but below grade. (See Figure C.1.4.) The platform is 183 m (600 ft) long to accommodate the train length. The vertical distance from grade to concourse is 8 m (26 ft). The concourse is 5.5 m (18 ft) above the platform. Figure C.1.4 Side-Platform Station. The sample station has two entrances normally used by patrons, each containing one escalator and one stair. The entrances are covered at grade level to a point 3.05 m (10 ft) beyond the top of the stairs. The concourse is divided into two free areas and one paid area separated by fare arrays. Each fare array contains 12 fare gates of the turnstile type and one swinging service gate, 1220 mm (48 in.) wide, equipped with panic hardware for use by handicapped persons and service personnel. Three open wells, containing two stairs and one escalator, communicate between each platform and the concourse. Elevators are provided from grade level to concourse and from the concourse to each platform for use by handicapped persons and service personnel. Station ancillary spaces are located at concourse level. Enclosed emergency stairs that discharge directly to grade are provided at both ends of each platform. Escalators are nominal 1220 mm (48 in.) wide. Stairs regularly used by patrons are 1830 mm (72 in.) wide. Emergency stairs are 1220 mm (48 in.) wide. Doors to emergency stairs are 1220 mm (48 in.) wide. The station occupant load is 1600 persons, 228 on the outbound platform and 1372 on the inbound platform. Table C.1.4 lists the data for the exiting analysis of the sample side-platform station.
