d guidance. Smoking and working with open flame should not be permitted in any plant area, including areas used for the storage of flammable and combustible liquids or compressed gases. 3.5 Control of Ignition Sources 3.5.1 Control of Hot Work Cutting, welding, grinding, and work involving open flame should be controlled so that it does not present an undue risk of fire. NFPA 1, NFPA 51B, and NFPA 241 provide information and guidance for minimizing the risk of fires from hot work. A qualified fire watch should be provided during the hot-work activity and for at least one-half hour after completion of the hot work. 3.5.2 Control of Temporary or Portable Heat-Producing Equipment The fire protection program should identify the measures necessary to prevent portable heat-producing equipment from causing a fire. Underwriter Laboratories listed heat-producing equipment should be used. Temporary heating devices should be secured to prevent tip-over and be separated from combustible materials, equipment, and construction in accordance with their listing. For fuel-fired heating, the fuel storage, transfer and refueling systems, and operations should be in accordance with applicable NFPA codes and standards. The use of portable heat-producing equipment should be controlled in areas with radiological hazards or significant quantities of combustible material that present an exposure hazard to radioactive materials or systems important to safety. Chapter 41 of NFPA 1 and Chapter 5 of NFPA 241 present additional guidance and information. 3.5.3 Control of Smoking Smoking should be permitted only in designated areas. Where smoking is permitted, safe receptacles for smoking materials should be provided. Smoking should be prohibited in other areas of the plant, specifically in the vicinity of hazardous operations or combustible or flammable materials. “No Smoking” signs should be posted in these areas.
