These can causeburns if precautionary measures are not used.Workers should wear protective clothing madeof fire-resistant material. Pant cuffs, open

7、 pock-ets, or other places on clothing that can catchand retain molten metal or sparks should not beworn. High-top shoes or leather leggings andfire-resistant gloves should be worn. Pant legsshould be worn over the outside of high-topshoes. Helmets or hand shields that provide pro-tection for the fa

8、ce, neck, and ears, and a headcovering to protect the head should be used. Inaddition, appropriate eye protection should beused.Electrical Hazards. Electric shock can kill.However, it can be avoided. Live electricalparts should not be touched. The manufacturersinstructions and recommended safe pract

9、icesshould be read and understood. Faulty installa-tion, improper grounding, and incorrect opera-tion and maintenance of electrical equipmentare all sources of danger.All electrical equipment and the workpieceshould be grounded. The workpiece lead isnot a ground lead. It is used only to completethe

10、welding circuit. A separate connection isrequired to ground the workpiece. The work-piece should not be mistaken for a groundconnection.Basic Safety Precautions5Fumes and Gases. Many welding, cutting,and allied processes produce fumes and gaseswhich may be harmful to health. Avoid breath-ing the air

11、 in the fume plume directly above thearc. Do not weld in a confined area without aventilation system. Use point-of-welding fumeremoval when welding galvanized steel, zinc,lead, cadmium, chromium, manganese, brass, orbronze. Do not weld on piping or containersthat have held hazardous materials unless

12、 thecontainers have been inerted properly.Compressed Gas Cylinders. Keep caps oncylinders when not in use. Make sure that gascylinders are chained to a wall or other structuralsupport.Radiation. Arc welding may produce ultra-violet, infrared, or light radiation. Always wearprotective clothing and ey

13、e protection to pro-tect the skin and eyes from radiation. Shieldothers from light radiation from your weldingoperation.AWS also recommends a personal copy of “Arc Welding Safely,” “Fire Safety in Welding andCutting,” “Safety in Welding, Cutting, and Allied Processes,” and “The Independent Shops Gui
