National Fire Protection Association Report

Public Input No. 62-NFPA 76-2013 [ Section No. 1.1 [Excluding any Sub-Sections] ]

This standard provides requirements for fire protection of existing, new and altered telecommunicationsfacilities where telecommunications services such as telephone (landline, wireless) transmission, datatransmission, internet transmission, voice-over internet protocol (VoIP) transmission, and video transmissionare rendered to the public.

Statement of Problem and Substantiation for Public Input

Introductory remarks:

The 2012 edition of NFPA 1 Fire Code includes a new Chapter 36 entitled Telecommunication Facilities and Information Technology Equipment. This chapter consists solely of references to NFPA 75 (for IT equipment) and NFPA 76. This inclusion by reference of NFPA 76 was not done with consultation from members of the Technical Committee on Telecommunications. NFPA 76 was originally developed as a Recommended Practice and only in 2005 was changed into a Standard. It retains much material that is suitable for a recommended practice, but if enforced, does not apply equally to all telecommunications carriers because their own policies and practices are at variance with some of the recommendations. By including NFPA 76 in NFPA 1, it will greatly increase the level of enforcement brought to bear on telecommunications facilities. The changes proposed here are to achieve several aims. First, to limit the chances that AHJs will apply this standard retroactively; second, to remove some material that is either covered adequately in other standards and thus not necessary or is covered differently elsewhere, such as in the International Fire Code and; third, to make minor grammatical changes.

Substantiation for this change:

This change will emphasize to AHJs that the code is intended to be applied differently to existing facilities than to new ones. It is primarily a standard for new facilities, but has some material that can be applied to existing facilities as well.

Public Input No. 63-NFPA 76-2013 [ Section No. 1.3 ]

1.3 * Application

The provisions of this standard shall provide a reasonable level of protection from loss of life, property, andservice continuity from fire.

1.3.1 (new)

Existing facilities or spaces therein constructed and modified prior to February 7, 2005 shall be requiredto maintain the requirements enforced at the time of occupancy. Basic fire protection and life safetyrequirements required by NFPA 1 shall be used as the minimum code requirements for general fireprevention on all existing, new and altered facilities or the identified portions at the time of originaloccupancy approvals. The requirements of existing facilities are provided in Chapters 9 and 10.

1.3.1

The requirements of Chapter 4 shall determine the fire protection program for each facility.

1.3.2 *

For purposes of application of NFPA 101 and NFPA 5000, telecommunications facilities shall be classifiedas special purpose or as industrial low occupancy, respectively.

1.3.3

The provisions of this standard shall not be applied retroactively to facilities, equipment, structures, orinstallations that were existing or approved for construction or installation prior to the effective date of thestandard.

1.3.4 *

Building alterations or new equipment installations in existing facilities shall provide a reasonable level offire protection for the changed purposes of the facility.


This new section provides further guidance for AHJs in applying the standard. The date given is the effective date of the 2005 edition of NFPA 76, when it first was changed from a Recommended Practice into a Standard. The new text indicates two specific chapters that contain material that applies to existing facilities (and new ones), further emphasizing that the balance of the document is for new facilities only.

1.3.2 *

For purposes of application of NFPA 101 and NFPA 5000, all telecommunications facilities shall beclassified as special purpose or as industrial low occupancy, respectively.


Inclusion of the word “all” will mean that facilities under 500 square feet will now be classified as indicated. At present, these small facilities are ignored in NFPA 76, leading to some confusion as to how they should be classified. This will help remove this confusion.

The provisions of this standard shall not be applied retroactively to facilities, equipment, structures, orinstallations that were existing or approved for construction or installation prior to the effective date of the2005 edition of this standard. The basic fire prevention and life safety requirements of all facilities arefound in Chapters 9 and 10.


This new language will strengthen the proscription against retroactive application by AHJs of this standard. The 2005 edition was the first to be published as a Standard and not a Recommended Practice.

8.2.3.3

Elements of aisle containment and hot air collars shall be constructed of noncombustible materials, limitedcombustible materials, or materials that have a maximum flame spread index of 50 of 25 and a maximumsmoke development of 450 of 50 in accordance with one or more of the following:

(1) ASTM E 84, Standard Test Method for Surface Burning Characteristics of Building Materials

(2) UL 723, Standard for Test for Surface Burning Characteristics of Building Materials.


The installation of hot aisle/cold aisle barriers creates spaces that are very similar to room plenums. Section 4.3.11.4.5 of NFPA 90A has requirements for the materials used in the construction of air-handling unit room plenums.

4.3.11.4.5 Materials used in the construction of an air-handling unit room plenum shall be noncombustible or shall be limited combustible having a maximum smoke developed index of 50 and shall be suitable for continuous exposure to the temperature and humidity conditions of the environmental air in the plenum.

NFPA 90A defines Limited-Combustible:

3.3.21* Limited-Combustible (Material). Refers to a building construction material not complying with the definition of noncombustible material that, in the form in which it is used, has a potential heat value not exceeding 8141 kJ/kg (3500 Btu/lb), where tested in accordance with NFPA 259, Standard Test Method for Potential Heat of Building Materials and that includes either of the following: (1) materials having a structural base of noncombustible material, with a surfacing not exceeding a thickness of 3.2mm(1⁄8 in.) that has a flame spread index not greater than 50; or (2) materials, in the form and thickness used, having neither a flame spread index greater than 25 nor evidence of continued progressive combustion, and of such composition that surfaces that would be exposed by cutting through the material on any plane would have neither a flame spread index greater than 25 nor evidence of continued progressive combustion when tested in accordance with ASTM E 84, Standard Test Method for Surface Burning Characteristics of Building Materials, or ANSI/UL 723, Standard for Test for Surface Burning Characteristics of Building Materials.

Considering the definition of limited-combustible material, the requirements for materials used in the construction of a room plenum are a maximum flame spread index of 25, a maximum smoke developed index of 50 and a maximum potential heat value of 8141 kJ/kg (3500 Btu/lb).

The PI recommends a maximum flame spread index of 25 and a maximum smoke developed index of 50 without a potential heat requirement in order to correlate with the NFPA 90A general rule for materials in plenums; see 4.3.11.2.6 and 4.3.11.5.5 in the Second Draft Report for NFPA 90A-2015.

Public Input No. 72-NFPA 76-2013 [ New Section after 8.5.3.3 ]

Proposed New Section 8.5.3.4 & Annex for NFPA 76 Based on the 2012 Edition

New Definition with New Annex Text Adjacent to the Definition

3.8.6* Ventilation Air Envelope. The volume of ventilation air confined by aisle containment or hot aircollars the purpose of which is to cool specific equipment.

A.3.8.6 The volume of confined cooling air flowing toward equipment intended to cool the equipment is thesupply ventilation air envelope. The volume of confined heated air flowing away from equipment havingbeen used to cool the equipment is the exhaust ventilation air envelope.

New Requirements with New Annex Text Adjacent to Each Requirement

8.5.3.4* Automatic Detection Equipment for Aisle Containment. Where aisle containment and hot aircollar systems are installed, the requirements of 8.5.3.4.1 through 8.5.3.4.5 shall apply to fulfill theapplicable detection requirements contained in a fire risk analysis in accordance with Chapters 1 and 4.

A.8.5.3.4 Fires that may harm signal-processing equipment may originate in the building that houses thesignal-processing equipment area, in the IT equipment area, in equipment that supports the signal-processing equipment such as HVAC and power systems, or (rarely) within the signal-processingequipment.

In signal-processing facilities that do not include HVAC containment, it has been common practice to designand install fire detection systems that are intended to provide adequate warning for both the signal-processing equipment and the signal-processing equipment area. Where high air changes in the signal-processing equipment area are present to cool signal-processing equipment, and a common fire detectionsystem is used to warn of fire for both the signal-processing equipment and the signal-processingequipment area, it has been necessary to design and install the detection system for the high air changespresent. This technique relies upon dispersion of products of combustion into the volume of the signal-processing equipment area where it can be detected.

Where HVAC containment is installed to increase the effectiveness of equipment cooling, by channeling theventilation air, the practice of detecting products of combustion dispersed in the signal-processingequipment area may not be an effective method to detect small fires that may originate in the cooledequipment. Products of combustion in the exhaust ventilation air envelope that do not disperse into thesignal-processing equipment area cannot be detected by detection equipment in the signal-processingequipment area.

Therefore, to detect products of combustion that originate in signal-processing equipment provided withHVAC containment, the detection equipment must be located in the exhaust ventilation air envelopes.

Where fire detection equipment is installed to provide adequate detection of fires or overload in the signal-processing equipment, detection systems installed to meet building code requirements or to provideadequate fire detection for the building or signal-processing equipment area need not be designed toprotect the signal-processing equipment.

Where HVAC systems are dedicated to cooling signal-processing equipment, those systems are associatedwith the signal-processing equipment contents of the building. The dedicated HVAC systems would not bepresent if the signal-processing equipment were not present. Therefore, it is not necessary to provide theclosely spaced detectors/ports (required for high air change) for the building or signal-processingequipment area detection system (since the building or signal-processing equipment area detection systemneed only be adequate for the building or signal-processing equipment area without its contents) providedthat the signal-processing equipment (contents) is provided with an adequate detection system(s).

8.5.3.4.1 Automatic Detection Equipment for Signal-Processing Equipment. The installation ofautomatic detection equipment that is designed to provide adequate warning of a fire in the signal-processing equipment shall be permitted.

8.5.3.4.1.1* The installation of automatic detection equipment within the ventilation air envelopes to providewarning of a fire within the signal-processing equipment cooled by the ventilation air shall be permitted.

A.8.5.3.4.1.1 Products of combustion follow forced air streams early in the development of a fire, oroverheat condition, when the influence of mechanical systems is greater than the buoyant forces of the fireor overheat condition. Detection system sensors or ports installed in the paths of cooling air exhaust from


20 of 87 6/11/2014 8:15 AM

the cooled equipment can be expected to respond to a small fire in the equipment sooner than sensors orports located outside of the ventilation air envelope. To be effective, the detection equipment installedwithin the ventilation air envelope should be suitable for the temperatures, air velocities and otherconditions 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 issufficient to overcome the mechanical forces of the HVAC containment system.

8.5.3.4.1.2 Where all signal-processing equipment in a signal-processing equipment area is provided withautomatic detection equipment permitted in 8.5.3.4.1 or 8.5.3.4.1.1, the requirement of 8.5.3.4.2 shall applyto the entire signal-processing equipment area.

8.5.3.4.1.3* Where only a portion of the signal-processing equipment is provided with automatic detectionequipment permitted in 8.5.3.4.1 or 8.5.3.4.1.1, the requirement of 8.5.3.4.2 shall be applied within eacharea separated by fire rated construction.

A.8.5.3.4.1.3 Sections 6.2 and 7.2 require the signal-processing equipment area to be separated from otheroccupancies by fire-rated construction. In addition, large signal-processing equipment installations may beseparated into more than one signal-processing equipment area.

8.5.3.4.2* Automatic Detection Equipment for the Signal-Processing Equipment Area and Signal-Processing Equipment Support Spaces. Where automatic detection equipment is installed to providesignal-processing equipment fire detection in accordance with 8.5.3.4.1 or 8.5.3.4.1.1, the installation of anautomatic detection system that is designed to provide adequate warning of a fire based on the buildingoccupancy classification or this standard shall be permitted without regard to the signal-processingequipment contents and the HVAC containment systems dedicated to the direct support of the signal-processing equipment.

A.8.5.3.4.2 Where fire detection equipment is installed to detect fire in the signal-processing equipmentwithin a signal-processing equipment area, and the design of the automatic detection equipment includeselements to address the effects of the environment necessary to support equipment operations, such ashigh air movement, a detection system installed as required for the building or signal-processing equipmentarea is not required to include elements to protect the signal-processing equipment in its environment. Forinstance, if an office building is constructed with a fire detection system suitable for the office environment,it is adequate for the building. When signal-processing equipment is added to the office building and adetection system(s) is added to the signal-processing equipment in accordance with 8.5.3.4.1 or8.5.3.4.1.1, the building detection system need not be changed, as permitted by 8.5.3.4.2, except as maybe necessary to comply with 8.5.3.4.3.

8.5.3.4.3* Automatic Detection Equipment for Exposure to Signal-Processing Equipment. Whereautomatic detection equipment is installed to fulfill the function described in 8.5.3.4.1 and 8.5.3.4.1.1 is notcapable of providing adequate warning of fire exposure to the signal-processing equipment from othernearby equipment or hazard condition, automatic detection equipment shall be installed to provideadequate warning of fire in the exposing equipment or hazard condition.

A.8.5.3.4.3 Examples of potentially exposing hazards may include large power systems, rectifiers, enginegenerators, staging areas or storage spaces containing combustible material.

8.5.3.4.4 Combined System. The installation of a system that combines the warning functions of8.5.3.4.1, 8.5.3.4.2 and 8.5.3.4.3 in a single fire detection system shall be permitted.

8.5.3.4.5* Consolidated Alarms and Alerts. Where separate automatic detection equipment or systemsare installed to perform the functions described in 8.5.3.4.1, 8.5.3.4.2 and 8.5.3.4.3, fire alarm, supervisoryand trouble signals shall be consolidated in a listed fire warning system to provide unified fire warninginformation to persons responsible for response to fire alarm, pre-alarm, supervisory and trouble signals.

A.8.5.3.4.5 Refer to NFPA 72, National Fire Alarm and Signaling Code, for definitions and functions of firealarm, supervisory and trouble signals. Some automatic detection systems are capable of providingpre-alarm signals that warn of a lower level of products of combustion than the level necessary to initiate analarm signal. If the listed system in which the signals are consolidate is capable of receiving pre-alarmsignals, those pre-alarm signals should be displayed in that system as well as alarm, supervisory andtrouble signals.

Similar public inputs for a new section and definition have been submitted to NFPA 75 and 76 in response to the joint task group formed by the two technical committees to propose requirements for fire detection and protection in the presence of cooling air containment systems. FPRF has organized a project to support this effort which may permit the addition of quantifiable requirements. This proposed new section and annex material provide qualitative requirements and explanations of the physical principles involved. These qualitative requirements are appropriate whether or not the FPRF project enables the addition of quantitative guidance. It is important that NFPA 75 and 76 harmonize requirements for fire detection in the presence of cooling air containment. The parallel input for new sections in both documents will provide harmonized requirements when adopted.

This public input replaces the text of NFPA 76 related to materials in ceiling cavity plenums and raised floor plenums by the corresponding text extracted from NFPA 90A. This avoids problems of contradictory requirements. The text typed in is the text from NFPA 90A 2012 but the extract should be from the most recent edition and the 90A committee is preparing the next edition.

The use of the Flame and Smoke Test in the Appendix to CSA C22.2 No. 0.3-M-1996 (FT6 Rating) isconsidered equivalent to the use of the NFPA 262 test.


This is an alternate approach to extracting material from NFPA 90A to avoid contradicting requirements. As opposed to the other public input on this section, this public input addresses exclusively wiring and the associated raceways. NFPA 90A does not allow cable routing assemblies into plenums unless they were tested as the default materials (i.e. to ASTM E84 with 25/50 flame spread index and smoke developed index). The extracted text proposed is from the 2012 edition of NFPA 90A but the committee is working on the next edition and the recommendation is that the next edition be used for extract.

9.1.1 * Removal or Storage of Combustibles.

Combustibles shall be removed daily or from telecommunications equipment areas at regular intervals orshall be stored appropriately in protected storage rooms, noncombustible enclosed storage cabinets orbins, noncombustible covered refuse containers, or listed self-extinguishing-type trash receptacles.


Combustible removal required in NFPA 76 should apply only to telecommunications equipment areas and not to the facility generally. Combustible removal in general is adequately covered in NFPA 1, 10.19 and in the IFC, 315.3.3. In addition, combustibles are not commonly removed daily, but certainly should be removed regularly. The language was changed to reflect that.

70 of 87 6/11/2014 8:15 AM

Smoke management for telecommunications facilities is different from smoke management applications forhigh-rise buildings or tall atria as prescribed in NFPA 92 and NFPA 204. This annex is intended to providedesign guidance on the application of smoke management systems for telecommunications facilities giventhe unique applications. Note in this application, smoke management systems are not intended for lifesafety and emergency egress of building occupants as they are in other industry applications. Given that,the requirements of those other standards intended to support life safety functions are not intended to applyto the application to telecommunications facilities. The reasons for smoke management systems in thisapplication are as follows:

(1) To allow fire department personnel or operating personnel sufficient visibility to approach, locate,depower equipment, and extinguish a fire without depowering the entire network facility

(2) To prevent damage to equipment and loss of emergency communication systems

(3) To provide means for rapid removal of smoke to permit continued cooling operations and preventindirect damage to equipment from thermal effects and eventual loss of emergency communicationsystems

The smoke management system is intended to provide emergency removal of smoke containments fromnetwork equipment and power spaces in telecommunications buildings. Smoke removal is considered animportant priority after a fire has been detected. Given the construction of the materials typically present intelecommunications spaces, damaging smoke and its subsequent removal require a higher priority thancontinued progression of a Class C fire, assuming the fire suppression (if present) is unable to extinguishthe source. The fires associated with telecommunications switching equipment rooms are typically Class C,slow-burn fires (e.g., electrical fires or energy-augmented fires), involving little to no flame but with largeamounts of smoke generation. It is desirable that the network equipment remain in operation throughout theduration of a fire. Because these facilities often provide emergency communications, in only the mostextreme cases should the facility be completely depowered as result of a fire or disaster. Smokemanagement systems installed in signal-processing areas are intended to protect the electronic equipmentfrom being exposed to the caustic and damaging contents of the smoke, thereby preventing circuit bridging,circuit pack failures, and large loss of equipment within these spaces. In addition, the smoke managementsystem is intended to maintain the smoke layer above a minimum height necessary to allow depoweringoperations by operating personnel and local fire-fighting authorities. The smoke management system alsoshould serve as a smoke purge system to remove smoke after a fire by means of dilution ventilation.

Typical design objectives of the smoke management system are as follows:

(1) To remove smoke from the signal-processing areas

(2) To remove smoke from design fires associated with cabling, trays, equipment, and associatedpackaging materials that may be in the space being protected

(3) To provide the necessary makeup air

(4) To remove smoke quickly enough to maintain the smoke above equipment racks during theworst-case design fire scenario to protect the equipment from smoke damage and allow fordepowering efforts

Three distinct design approaches are commonly used for the smoke management systems used intelecommunications facilities, as follows:

(1) Smoke management — removal of smoke products during a fire event (during depowering efforts)

(2) Smoke removal — rapid removal of the smoke products after a fire event via dilution ventilation

(3) Smoke control — control of the spread of smoke to rooms that are not involved in the fire event; takesplace from initial fire alarm through completion of the smoke removal of the affected zone until normaloperations resume

The design approach for smoke management should be based upon NFPA 92 using the following criteria:

(1) t 2 design fire

(2) Very slow growth fire, >600 sec

(3) Makeup air quantities should be permitted equivalent to the exhaust air quantities for a given space

The design approach for smoke removal should be based on dilution ventilation sufficient to remove smokewithin a time frame acceptable to the owner and within sufficient time to prevent thermal failure of signal-


71 of 87 6/11/2014 8:15 AM

processing equipment after fire has been extinguished. Dilution ventilation can be calculated using thelogarithmic calculation found in Principles of Smoke Management. To take a fire alarm system out of alarm,the smoke concentration needs to be diluted below the sensitivity level of the smoke detectors. The designshould be permitted to be based on the worst-case calculation from a smoke management or smoke purgedesign approach.

Calculations for design fire cases should be permitted to be derived from generally accepted engineeringpractice.

It is important for the system designer to be aware of the limitations for any equations used in the design.Some of them may be applicable only under a limited range of conditions that may or may not be present inthe job being designed.

Typical assumptions used in a performance-based design can include the following:

(1) Good housekeeping practices are strictly followed, in which no amounts of combustible or flammablematerials are stored in the critical equipment rooms.

(2) No combustible materials are located under raised floors.

(3) Telecommunications equipment or cabling involved in a fire will be depowered within 1 hour of EWFDalarm.

(4) The smoke management system will operate after the fire suppression system (if present).

(5) Airflow is designed for smoke management during a fire event to maintain the smoke layer aboveequipment racks; airflow is also designed to be of sufficient rate to completely remove smoke withinsufficient time to prevent thermal failure of the network equipment involved.

Smoke management systems should be provided in signal-processing equipment areas.

Refer to NFPA 92 and NFPA 101 for requirements of pressure control to ensure proper operation ofdoorways during system operation.

Smoke management systems should be permitted to be designed using applicable design calculationsfound in NFPA 92, NFPA 204, or Principles of Smoke Management using design fires in all spaces servedby the smoke management system.

Equipment suitable for its intended use and the probable temperatures to which it is likely to be exposedshould be permitted. Exhaust fans UL-listed for smoke management/control systems and carrying theUL-705 label or certified by the manufacturer to meet the minimum temperature and time requirementsshould be permitted. Smoke exhaust fans should be tested following ASHRAE 149-200 .

Smoke dampers should be listed in accordance with UL 555S. Combination fire and smoke dampersshould be listed in accordance with UL 555 and UL 555S. Dampers should be suitable for their intendeduse and the probable temperatures to which they are likely to be exposed. When present, dampers shouldhave override capability for smoke management system operations. Damper override should not bepermitted to close until temperatures exceed 177°C (350°F) in the duct. Dampers should be provided withlimit switches used for verification of damper position in the control system and to ensure safe HVACequipment operation.

Duct materials should be selected and designed to convey smoke, withstand additional pressure (bothpositive and negative) by the supply and exhaust fans when operating in a smoke-control mode, andmaintain their structural integrity during the period for which the system is designed to operate. Ductssuitable for their intended use and the probable temperatures to which they are likely to be exposed shouldbe permitted.

Control systems listed in accordance with UL 864, Standard for Control Units and Accessories for FireAlarm Systems, category UUKL for their intended purpose should be permitted.

A fire fighters' smoke-control station (FSCS) per NFPA 92, Annex H should be permitted. On/off/autoselectable switches (one per zone) should be permitted. An FSCS located behind locked cover forprotection in public areas should be permitted. An FSCS located adjacent to a fire alarm panel or asdirected by AHJ should be permitted.

A single control system or fire alarm system coordinating the smoke-control functions, FSCS, and any otherrelated systems with the operation of the building HVAC systems and smoke-control equipment should bepermitted.

A strobe light mounted at every entry point and labeled “EMERGENCY SMOKE MANAGEMENT SYSTEM

There is a reference to ASHRAE Standard 149in A8.7.2, but the year is not complete (200), so it’s not clear what version is referenced, though based on the extra 2000 in G1.2.2, it’s likely the 2000 version of the standard. This proposal cleans up the text, and proposes a reference to the most recent published version of the standard.In 1992, ASHRAE and SFPE jointly published Design of Smoke Management Systems. The term smoke management was used in the title of this publication to indicate that the physical mechanisms were expanded from pressurization and airflow to include compartmentation, dilution, and buoyancy. Based on heightened concerns about supplying combustion air to the fire, a caution was added about the use of airflow for smoke management.In 2002, ASHRAE and SFPE jointly published Principles of Smoke Management. This publication included the material of the two earlier books plus people movement in fire, hazard analysis, scale modeling, and computational fluid dynamics.This new publication is in handbook form that is intended to make the book more useful to practicing engineers. The earlier books were aimed at both practicing engineers and students, and derivations of equations were included in many of the chapters. To make the handbook easier to use for engineers who want information on a specific topic quickly, the derivations are not included in the chapters. However, to make the book useful to students and teachers, the derivations are in an appendix.

B.2.1

This test uses an electrically overloaded PVC-coated wire to simulate the early stages of a fire. Although aPVC wire is used, hydrogen chloride vapor is unlikely to be produced in quantities significant enough to beof concern, if the test procedures herein are followed, due to the relatively low temperatures reached. If thecurrent is applied for a longer time, or if the wire sample is shorter than stated, small quantities of hydrogenchloride can be generated. In either event, a clearly perceptible odor that should dissipate in short time isproduced by the test.

The tests are based on the test specified in Section A.3 of BS 6266. The principal differences for sometests include the use of a regulated dc power supply and different wire, electrical load, and wire length.

Users are directed to Table B.2.1 to select the parameters to be used during the testing.

There is a reference to ASHRAE Standard 149in A8.7.2, but the year is not complete (200), so it’s not clear what version is referenced, though based on the extra 2000 in G1.2.2, it’s likely the 2000 version of the standard. This proposal cleans up the text, and proposes a reference to the most recent published version of the standard.In 1992, ASHRAE and SFPE jointly published Design of Smoke Management Systems. The term smoke management was used in the title of this publication to indicate that the physical mechanisms were expanded from pressurization and airflow to include compartmentation, dilution, and buoyancy. Based on heightened concerns about supplying combustion air to the fire, a caution was added about the use of airflow for smoke management.In 2002, ASHRAE and SFPE jointly published Principles of Smoke Management. This publication included the material of the two earlier books plus people movement in fire, hazard analysis, scale modeling, and computational fluid dynamics.This new publication is in handbook form that is intended to make the book more useful to practicing engineers. The earlier books were aimed at both practicing engineers and students, and derivations of equations were included in many of the chapters. To make the handbook easier to use for engineers who want information on a specific topic quickly, the derivations are not included in the chapters. However, to make the book useful to students and teachers, the derivations are in an appendix.
