FIRE OR EXPLOSION
Welding can cause fires and explosions. Precautions should be taken to
prevent these hazards.
• Before starting work ensure the area is clear of flammable materials.
• Move any combustible materials to a safe distance, especially substances
likely to generate a dangerous vapour.
• The welding arc can cause serious burns. Avoid contact with the skin.
• Sparks and molten metal are ejected during welding. Take precautions to
prevent fire.
• Sparks and molten metal can pass through gaps. Be aware that fire can
start out of sight.
• Do not weld pressurised containers. or containers containing flammable
vapours e.g. fuel tanks.
• Always have appropriate fire fighting equipment to hand suitable for use in
electrical environments.
• Avoid carrying any fuels with you e.g. cigarette lighters or matches.
PERSONAL PROTECTION
• The body should be protected by suitable clothing.
• The use of neck protection may be necessary against reflected radiation.
• Arc welding machines generate a magnetic field which is detrimental to
pacemakers. Consult your doctor before going near active welding
equipment/operations.
• The UV and IR radiation generated by welding is highly damaging to the
eyes, causing burns. This can also affect the skin.
• Always use a suitable welding shield equipped with appropriate protective
filters.
• Where there are pedestrians and traffic, ensure a protective screen is used
to avoid accidental arc glare.
• Do not weld in the vicinity of children or animals and ensure no one is looking
before striking an arc.
• Wear hearing protection if required.
• Allow the weld time to cool. Hot metal should never be handled without
gloves.
• Take care when adjusting or maintaining the torch. Make sure it has had
time to cool sufficiently and the welder is disconnected from the mains
supply.
• First aid facilities and a qualified first aid person should be available unless
medical facilities are close by, for immediate treatment of flash burns of the
eyes and for skin burns.
• A hard hat should be worn when others are working overhead.
