Use and Handling of Compressed and Liquefied Gases in Portable Cylinders; Tentative Interim Amendment - 1995
|Publication Date:||1 January 1993|
This standard applies to the storage, use, and handling of compressed and liquefied gases in portable cylinders in all occupancies.
This standard shall not apply to:
(a) The off-site transportation of compressed gases.
NOTE: For regulations on the transportation of gases see the Code of Fderal Regulations, 49 CFR parts 100 to 179 (Transportation) and Transportation of Dangerous Goods Regulations of Transport Canada.
(b) Storage, use, and handling of cylinders at gas manufacturer and distributor facilities.
(c) The storage, use, and handling of radioactive gases.
(d) The storage, use, and handling of medical gases at health care facilities.
NOTE: For information on storage of medical gases at health care facilities see NFPA 99, Standard for Health Care Facilites.
(e) Cryogenic liquids in bulk and portable containers.
(f) Systems for gases, each containing more than 20,000 SCF (566 Sm3) of oxygen, 3,000 SCF (85 Sm3) of hydrogen, 5,000 SCF (142 Sm3) of acetylene.
NOTE: For information on systems of more than 20,000 SCF (DG6 Sm3) of oxygen see NFPA 50, Standard for Bulk Oxygen Systems at Consumer Sites. For information on systems of more than 3,000 SCF (85 Sm3) of hydrogen see NFPA 50A, Standard for Gaseous Hydrogen System at Consumer Site. For information on storage of more than 5,000 SCF (142 Sm3) of acetylene see NFPA 51, Standard for the Design and Installation of Oxygen-Fuel Gas Systems for Welding, Cutting, and Allied Processes.
(g) Storage and use of more than a total of 735 lb (333 kg) water capacity [nominal 300 Ib (136 kg) propane] of liquefied flammable gases.
NOTE: For information on storage and use of more than 735 lb (333 kg) water capacity [nominal 300 Ib (136 kg) propane] of liquefied flammable gas see NFPA 58, Standard for the Storage and Handling of Liquefied Petroleum Gases
(h) Systems consisting of a single cylinder of oxygen and a single cylinder of fuel gas used for welding and cutting.
(i) Compressed and liquefied gases in separate storage areas in quantities less than those specified in Tables 1-1.2(a) and 1-1.2(b), except as specified elsewhere in this standard.
(i) Flammable gases used as a vehicle fuel when stored on the vehicle.
NOTE: For information see NFPA 52, Standard for Compressed Natural Gas (CNG) Vehicular Fuel Systems or NFPA 58, Standard for the Storage and Handling of Liquefied Petroleum Gases.
(k) The handling and use of compressed or liquefied gases in laboratory work areas covered by NFPA 45, Standard on Fire Protection for Laboratories Usiizg Chemicals.
NOTE: The storage of gases outside of laboratory work areas are covered by this standard.
