SAFETY
2-3
• Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves
and collars should be kept buttoned (closed) and open pockets should be
eliminated from the front of the clothing.
• Protect other personnel from arc rays and hot sparks with a suitable non-flammable
partition or curtains. Post warning signs advising others not to watch the welding
arc or be in direct exposure to the active arc without proper protection.
• Use goggles or face shields over safety glasses when chipping slag or grinding.
Chipped slag may be hot and can fly for long distances. Bystanders should also wear
goggles over safety glasses.
2.1.3 FIRES AND EXPLOSIONS
Therefore:
1. Protect yourself and others from flying sparks and hot metal.
2. Remove all combustible materials well away from the work area or cover the
materials with an approved protective non-flammable covering. Combustible
materials include wood, cloth, sawdust, liquid and gas fuels, solvents, paints, and
coating paper, etc.
3. Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings
and cause a hidden smoldering fire or fires on the floor below. Make certain that
such openings are protected from hot sparks and metal.
4. Follow the "hot work" procedures for the location. This can include a fire watch
person who monitors the sparks during the work, the requirement for a formal work
permit and the surveillance of the scene for an extended period of time to ensure no
smoldering fires are developing.
5. Do not weld, cut, or perform other hot work until the work piece has been
completely cleaned so that there are no substances on or in the work piece which
might produce flammable or toxic vapors. Do not perform hot work on closed
containers, they may explode.
6. Have fire extinguishing equipment handy for instant use, such as a garden hose,
water pail, sand bucket, or portable fire extinguisher. Be sure you are trained in its
use.
7. Do not use equipment beyond its ratings. For example, an overloaded welding cable
can overheat and create a fire hazard.
FIRE HAZARD: Sparks (spatter) can cause fire.
