Do not wear gloves or other clothing that contain oil, grease, or other
•
flammable substances.
Do not wear flammable hair preparations.
•
Do not weld in an area until it is checked and cleared of combustible
•
and/or flammable materials. BE AWARE that sparks and slag can fly
35 feet and can pass through small cracks and openings. If work and
combustibles cannot be separated by a minimum of 35 feet, protect
against ignition with suitable, snug-fitting, fire resistant, covers or shields.
Do not weld on walls until checking for and removing combustibles
•
touching the other side of the walls.
Do not weld, cut, or perform other such work on used barrels, drums,
•
tanks, or other containers that had contained a flammable or toxic
substance. The techniques for removing flammable substances and
vapors, to make a used container safe for welding or cutting, are quite
complex and require special education and training.
Do not strike an arc on a compressed gas or air cylinder or other
•
pressure vessel. Doing so will create a brittle area that can result in
a violent rupture immediately or at a later time as a result of rough
handling.
Do not weld or cut in an area where the air may contain flammable dust
•
(such as grain dust), gas, or liquid vapors (such as gasoline).
Do not handle hot metal, such as the workpiece or electrode stubs, with
•
bare hands.
Wear leather gloves, heavy long sleeve shirt, cuffless trousers, high-
•
topped shoes, helmet, and cap. as necessary, use additional protective
clothing such as leather jacket or sleeves, fire resistant leggings, or
apron. Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs,
or pockets. Sleeves and collars should be kept buttoned and pockets
eliminated from the shirtfront.
Have fire-extinguishing equipment handy for immediate use! A portable
•
chemical fire extinguisher, type ABC, is recommended.
Wear earplugs when welding overhead to prevent spatter or slag from
•
falling into ear.
Make sure welding area has a good, solid, safe floor, preferably concrete
•
or masonry, not tiled, carpeted, or made of any other flammable material.
Protect flammable walls, ceilings, and floors with heat resistant covers or
•
shields.
check welding area to make sure it is free of sparks, glowing metal or
•
slag, and flames before leaving the welding area.
