APPENDIX F HAZARD RANKING The provisions contained in this appendix are not mandatory unless specifically referenced in the adopting ordinance or legislation of the jurisdiction. User note: About this appendix: Appendix F is intended to be a companion to the specific requirements of Chapters 51 through 67, which regulate the storage, handling and use of all hazardous materials classified as either physical or health hazards. These materials pose diverse hazards, including instability, reactivity, flammability, oxidizing potential or toxicity; therefore, identifying them by hazard ranking is essential. This appendix lists the various hazardous material categories that are defined in this code, along with the NFPA 704 hazard ranking for each.

The hazard rankings shown in Table F101.2 have been established by using guidelines found STANDARD STANDARD NAME SECTIONS within NFPA 704. As noted in Section 4.2 of NFPA 704, ACRONYM HEREIN there could be specific reasons to alter the degree of hazard assigned to a specific material; for example, ignition NFPA 70—20 National Electrical Code REFERENCED temperature, flammable range or susceptibility of a container NFPA 704—17 to rupture by an internal combustion explosion or to metal Identification of the Hazards Table F101.2 failure while under pressure or because of heat from external of Materials for Emergency fire. As a result, the degree of hazard assigned for the same F101.1, F101.2 material can vary when assessed by different people of equal Response competence. The hazard rankings assigned to each class represent reasonable minimum hazard levels for a given class based on the use of criteria established by NFPA 704. Specific cases of use or storage may dictate the use of higher degrees of hazard in certain cases. 2021 INTERNATIONAL FIRE CODE® APPENDIX F-1 EDUFIRE.IR Telegram: EDUFIRE.IR

APPENDIX G CRYOGENIC FLUIDS—WEIGHT AND VOLUME EQUIVALENTS This appendix is for information purposes and is not intended for adoption. User note: About this appendix: Appendix G gives the fire code official and registered design professional a ready reference tool for the conversion of the liquid weight and volume of cryogenic fluid to their corresponding volume of gas and vice versa and is a companion to the provisions of Chapter 55 of this code. SECTION G101 GENERAL G101.1 Scope. This appendix is used to convert from liquid to gas for cryogenic fluids. G101.2 Conversion. Table G101.2 shall be used to deter- mine the equivalent amounts of cryogenic fluids in either the liquid or gas phase. G101.2.1 Use of the table. To use Table G101.2, read horizontally across the line of interest. For example, to determine the number of cubic feet of gas contained in 1.0 gallon (3.785 L) of liquid argon, find 1.000 in the column entitled “Volume of Liquid at Normal Boiling Point.” Reading across the line under the column entitled “Volume of Gas at NTP” (70°F and 1 atmosphere/14.7 psia), the value of 112.45 cubic feet (3.184 m3) is found. G101.2.2 Other quantities. If other quantities are of interest, the numbers can be multiplied or divided to obtain the quantity of interest. For example, to determine the number of cubic feet of argon gas contained in a volume of 1,000 gallons (3785 L) of liquid argon at its normal boiling point, multiply 112.45 by 1,000 to obtain 112,450 cubic feet (3184 m3). 2021 INTERNATIONAL FIRE CODE® APPENDIX G-1 EDUFIRE.IR Telegram: EDUFIRE.IR

APPENDIX K CONSTRUCTION REQUIREMENTS FOR EXISTING AMBULATORY CARE FACILITIES The provisions contained in this appendix are not mandatory unless specifically referenced in the adopting ordinance or legislation of the jurisdiction. User note: About this appendix: Appendix K was created with the intent to provide jurisdictions with an option for assessing minimum fire and life safety requirements for buildings containing ambulatory care facilities. While this appendix is written with the intent to apply retroactive mini- mum standards, it is recognized that the ambulatory care requirements are relatively recent additions to the International Building Code®. For that reason, these requirements are presented as an appendix so that the adopting authority can exercise judgment in the adoption and application of this section. This appendix would also be useful for those local and state jurisdictions that are specifically focused on ensuring the safety of existing ambulatory care facilities by providing minimum criteria that could be used to bring older facilities into compliance with the current standards at the discretion of the adopting jurisdiction. The technical requirements are based on the current International Build- ing Code language, which is consistent with the overall concept of the current federal requirements.

APPENDIX L REQUIREMENTS FOR FIRE FIGHTER AIR REPLENISHMENT SYSTEMS The provisions contained in this appendix are not mandatory unless specifically referenced in the adopting ordinance or legislation of the jurisdiction. User note: About this appendix: Appendix L provides for the design, installation and maintenance of permanently installed fire fighter breathing air systems in buildings designated by the jurisdiction. Breathing air is critical for fire-fighting operations. Historically, fire departments have supplied air bottles by means of a “bottle brigade,” whereby fire fighters manually transport air bottles up stairways, which is an extraordi- narily fire fighter-intensive process and takes fire fighters away from their primary mission of rescue and fire fighting. Technology now exists to address the issue using in-building air supply systems. Fire fighter breathing air systems were introduced in the late 1980s and are now required in a number of communities throughout the United States. The system has been called a “standpipe for air” and consists of stain- less steel, high-pressure piping that is supplied by on-site air storage or fire department air supply units. Air-filling stations are then strategically located throughout the building, allowing fire fighters to refill breathing air cylinders inside the fire building, negating the required “bottle brigade,” and making more fire fighters available for search, rescue and fire suppression operations.

User note: About this appendix: Appendix M was created with the intent to provide an option for adoption by jurisdictions that choose to require exist- ing high-rise buildings to be retrofitted with automatic sprinklers. Modern fire and building codes require complete automatic fire sprinkler protection and a variety of other safety features in new high-rise construction. Many older high-rise buildings lack automatic sprinkler protection and other basic fire protection features necessary to protect the occupants, emergency responders and the structure itself. With- out complete automatic sprinkler protection, fire departments cannot provide the level of protection that high-rise buildings demand. Existing high-rise buildings that are not protected with automatic sprinklers represent a significant hazard to occupants and fire fighters, and can significantly impact a community’s infrastructure and economic viability in the event of a fire loss. SECTION M101 SCOPE M101.1 Scope. An automatic sprinkler system shall be installed in all existing high-rise buildings in accordance with the requirements and compliance schedule of this appendix. SECTION M102 WHERE REQUIRED M102.1 High-rise buildings. An automatic sprinkler system installed in accordance with Section 903.3.1.1 shall be provided throughout existing high-rise buildings. Exceptions: 1. Airport traffic control towers. 2. Open parking structures. 3. Group U occupancies. 4. Occupancies in Group F-2. SECTION M103 COMPLIANCE M103.1 Compliance schedule. Building owners shall file a compliance schedule with the fire code official not later than 365 days after receipt of a written notice of violation. The compliance schedule shall not exceed 12 years for an auto- matic sprinkler system retrofit. 2021 INTERNATIONAL FIRE CODE® APPENDIX M-1 EDUFIRE.IR Telegram: EDUFIRE.IR

APPENDIX N INDOOR TRADE SHOWS AND EXHIBITIONS The provisions contained in this appendix are not mandatory unless specifically referenced in the adopting ordinance or legislation of the jurisdiction. User note: About this appendix: Appendix N was created to address the hazards that are associated with larger, more complex trade shows and exhibitions. Although many of these requirements are already included in various locations in this code, some of the more important items, such as requirements for covered booths and multiple-level booths, are not. The intent is to have the requirements covering these events in a single location with pointers to other locations within this code, which makes it easier for those organizing exhibitions and individual exhib- itors who are unfamiliar with the fire code to locate the requirements that are applicable to them.
