For materials that are detonable, the distance to other buildings or lot lines shall be as specified in the Building Code. For materials classified as explosives, the required separation distances shall be as specified in FC Chapter 56. Unclassified detonable organic peroxides (see FC Chapter 62), detonable pyrophoric materials (see FC Chapter 64), detonable unstable (reactive) materials (see FC Chapter 66) and detonable water-reactive materials (see FC Chapter 67) shall be treated as explosives for purposes of storage, handling and use (see FC Chapter 56). b. "Maximum Allowable Quantity" means the maximum allowable quantity per control area set forth in FC Table 5003.1.1(1). c. Limited to Division 1.4 materials and articles, including articles packaged for shipment, that are not regulated as an explosive under Bureau of Alcohol, Tobacco, Firearms and Explosives regulations, or unpackaged articles used in process operations that do not propagate a detonation or deflagration between articles, providing the net explosive weight of individual articles does not exceed 1 pound.
