IV. POTENTIAL IGINITION SOURCES <br />• Ensure that utility lights always have some type of wire guard over them. <br />• Don't misuse fuses. Never install a fuse rated higherthan specified for the circuit. <br />• Investigate any appliance or equipment that smells strange. Space heaters, microwave ovens, <br />hot plates, coffee makers and other small appliances shall be rigidly regulated and closely <br />monitored. <br />• The use of extension cords to connect heating devices to electric outlets shall be prohibited. <br />• If a hot or under inflated tire is discovered, it should be moved well away from the vehicle. As an <br />alternative, the driver should remain with the vehicle until the tire is cool to the touch, and then <br />make repairs. If a vehicle is left with a hot tire, the tire might burst into flames and destroy the <br />vehicle and load. <br />WELDING AND CUTTING <br />Welding and cutting will not be permitted in areas not authorized by management. <br />If practical, welding and cutting operations shall be conducted in well -ventilated rooms with a fire- <br />resistant floor. If this practice is not feasible, shall ensure that the work areas have been surveyed for <br />fire hazards; the necessary precautions taken to prevent fires; and issue a hot permit. This hot permit <br />shall only encompass the area, item and time which is specified on it. <br />If welding is to be performed over wooden or other combustibles type floors, the floors will be swept <br />clean, wetted down, and covered with either fire -retardant blankets, metal or other noncombustible <br />coverings. <br />Welding will not be permitted in or near areas containing flammable or combustible materials (liquids, <br />vapors, or dusts). Welding will not be permitted in or near closed tanks that contain or have contained <br />flammable liquids unless they have been thoroughly drained, purged and tested free from flammable <br />gases or vapors. Welding shall not begin until all combustible materials have been removed at least 35 <br />feet from the affected areas, or if unable to relocate, covered with a fire retardant covering. Openings in <br />walls, floors, or ducts shall be covered if located within 35 feet of the intended work area. Welding will <br />not be permitted on any closed containers. <br />Fire extinguishers will be provided at each welding or cutting operation. A trained watcher will be <br />stationed at all times during the operation and for at least 30 minutes following the completion of the <br />operation. This person will assure that no stray sparks cause a fire and will immediately extinguish fires <br />that do start. <br />OPEN FLAMES <br />No open flames will be permitted in or near spray booths or spray rooms. If indoor spray -painting work <br />needsto be performed outside of standard spray -painting booths, adequate ventilation will be <br />provided. All potential ignition sources will also be eliminated. <br />Cabarrus County has a specific policy regarding cigarette/cigar/pipe smoking in the workplace.
