Special metals require the use of respirators to protect the welders from harmful fumes.
Helmets and welding goggles must be free of cracks or holes that would permit the penetration of intense light. Avoid looking at the arc or flash unless equipped with appropriate dark glasses. Keep your sleeves and pant cuffs down, and your collar buttoned up. Wear protective clothing to help protect the skin from intense rays. Where necessary, wear leather aprons, arm coverings, or other protection to protect from molten metal of hot sparks.
