Ignition Source Control 6. Prohibit smoking in areas where combustibles are stored, where flammable liquids are stored or dispensed, near piles of debris, and on the roof. Post no smoking signs. Permit smoking only in designated areas equipped with proper receptacles. 7. The FM Global Hot Work Permit System should be used to monitor all applicable hot work operations. Temporary Storage 8. Keep temporary combustible storage in the yard or on the roof (such as combustible roof insulation) to a minimum and limit to 6 ft in height and one or two pallets in width. Where space permits, the separation distance between adjacent storage piles and structures should be at least 20 ft, 25 ft, or 30 ft, for exposing storage widths of 4 ft, 6 ft, and 8 ft, respectively. Equipment and High Value Storage 9. Arrange temporary storage of valuable and important equipment during construction in the following order of preference: (1) under sprinkler protection; (2) if no sprinklers, subdivided in moderate amounts in noncombustible buildings; and (3) if in combustible, unsprinklered buildings, provided with watch service, fire hose and extinguishers, heated by safe methods, and separated from other ignition sources. Subdivision in (2) above can be by walls with noncombustible surfaces or by clear spaces of 50 ft (15 m). When space and storage is limited, closer separation can be tolerated as outlined above (temporary storage).
