NFPA 484
Standard for Combustible Metals - Effective Date: 08/31/2011
Organization:
NFPA - (NFPA) - National Fluid Power Association
Year: 2012
Abstract: This standard shall apply to the production, processing, finishing, handling, recycling, storage, and use of all metals and alloys that are in a form that is capable of combustion or explosion.
The procedures in Chapter 4 shall be used to determine whether a metal is in a noncombustible form.
Combustible Metal Powder or Dust.
This standard also shall apply to operations where metal or metal alloys are subjected to processing or finishing operations that produce combustible powder or dust.
Operations where metal or metal alloys are subjected to processing or finishing operations that produce combustible powder or dust shall include, but shall not be limited to, machining, sawing, grinding, buffing, and polishing.
Metals, metal alloy parts, and those materials, including scrap, that exhibit combustion characteristics of alkali metals, aluminum, magnesium, tantalum, titanium, or zirconium shall be subject to the requirements of the metal whose combustion characteristics they most closely match.
Metals, metal alloy parts, and those materials, including scrap, that do not exhibit combustion characteristics of alkali metals, aluminum, magnesium, niobium, tantalum, titanium, or zirconium are subject to the requirements of Chapter 14.
This standard shall not apply to the transportation of metals in any form on public highways and waterways or by air or rail.
This standard shall not apply to the primary production of aluminum, magnesium, and lithium.
This standard shall apply to laboratories that handle, use, or store more than 0.23 kg (1⁄2 lb) of alkali metals or 0.907 kg (2 lb) aggregate of other combustible metals, excluding alkali metals.
All alkali metals and metals that are in a form that is water reactive shall be subject to this standard.
If the quantity of a combustible metal listed in Table 1.1.9 is exceeded in an occupancy, the requirements of this document shall apply
Purpose. The objective of this standard shall be to minimize the occurrence of, and resulting damage from, fire or explosion in areas where combustible metals or metal dusts are produced, processed, finished, handled, stored, and used.
The procedures in Chapter 4 shall be used to determine whether a metal is in a noncombustible form.
Combustible Metal Powder or Dust.
This standard also shall apply to operations where metal or metal alloys are subjected to processing or finishing operations that produce combustible powder or dust.
