7.When welding or cutting in small areas, the operator should be externally accompanied by another person (standing near the enclosed work area) to observe accident prevention procedures.
8.When welding or cutting, be aware that high frequency radiation may be produced which can interfere with radio navigation, safety devices, computers, and communications equipment. Before operating, have a qualified technician check out that possibility.
9.Keep high frequency source doors and panels tightly shut. Keep spark gaps at the correct settings. Use proper grounding and shielding to minimize the possibility of interference. Keep all cables close together and close to the ground. Locate the welding or cutting operation as far as possible from sensitive electronic equipment, or have the electronic equipment shut down temporarily.
10.Prevent accidental fires. Remove any combustible material from the work area. When possible, move the work to a location well away from combustible materials. If relocation is not possible, protect the combustibles with a cover made of fire resistant material. Remove or make safe all combustible materials for a radius of 35 feet (10 meters) around the work area. Use a fire resistant material to cover or block all open doorways, windows, cracks, and other openings. Enclose the work area with portable fire resistant screens. Protect combustible walls, ceilings, floors, etc., from sparks and heat with fire resistant covers. If working on a metal wall, floor, ceiling, etc., prevent ignition of combustibles on the other side by moving the combustibles to a safe location. If relocation of the combustibles is not possible, designate someone to serve as a fire watch, equipped with a fire extinguisher, during the welding process and at least one half hour after the welding is completed. Do not place the torch on any material other than bare concrete until the torch is completely cooled. Do not weld on materials having a combustible coating or combustible internal structure such as walls or ceilings, without an approved method for eliminating the hazard. Do not dispose of hot slag in containers holding combustible materials. Keep a fire extinguisher nearby, and know how to use it. After welding, make a thorough examination for evidence of fire. Be aware that easily visible smoke or flame may not be present for some time after the fire has started. Do not weld in atmospheres containing dangerously reactive or flammable gasses, vapors, liquids, and dust. Provide adequate ventilation in work areas to prevent accumulation of flammable gases, vapors, or dust. Do not apply heat to a container that has held an unknown substance or a combustible material whose contents, when heated, can produce flammable or explosive vapors. Clean and purge containers before applying heat. Vent closed containers, including castings, before preheating or welding. Note: Use caution when welding galvanized metal; toxic gases are formed and must be ventilated properly.
11.Read and understand all instructions and safety precautions as outlined in the manufacturer’s manual for the material you will weld.
