Weld in a well-ventilated area. Welding fumes should be ventilated away from the person welding, not across the welder's face. Remember that shielding gases are asphyxiants, and welding fumes are harmful. Work in well-ventilated areas to prevent suffocation or fume sickness. Never wear synthetic fiber clothing or weld with flammables in your pocket.
Synthetic fibers are highly flammable.
Do not allow bystanders to smoke in the welding area. Avoid electrical shock. Make certain that the electrode holder and all electrical connections and cables are properly insulated. Check to see that the welder is properly grounded. Do not dip the electrode holder in water to cool it because this practice may result in electrical shock.
