1.
Clear the floor and walls of an area of all combustible and/or flammable
materials up to 39 ft (12 metres) away from the welding unit. Hot debris
ejected during welding can land at a considerable distance away. Solid
floors of concrete or masonry is the preferred working surface.
a.
Cover any combustible material with fire resistant covers or shields, if
it cannot be removed. The covering must be tight and should not
leave openings for sparks or ejected slag to enter.
b.
Check both sides of a panel or wall for combustible material. Remove
the combustible material before welding.
2.
A combustible floor should be protected with a fire resistant covering.
Alternatives are to spray the floor with water to keep it wet for the duration
of the welding or cover with damp sand. Care must also be taken to avoid
an electric shock when this is done. A combustible floor directly laid onto
concrete does not need to be sprayed with water.
3.
Seal cracks and openings to adjacent areas that a spark or slag can enter.
Seal any openings found with a fire-resistant cover. Shut doors and windows
that do not provide ventilation or erect protective screens in front of them
when possible.
4.
Avoid welding near hydraulic lines or containers containing flammable
contents.
5.
Do not perform any welding work on containers that held flammable or
toxic substance, until they are cleaned by a person trained in removing
toxic and flammable substances and vapours per the American Welding
Standard AWS F4.1.
6.
Open a container before performing any welding work on it. The heat
generated by the welding process will cause the air and gases to expand.
The internal pressure may cause a sealed or closed container to rupture,
possibly causing an injury or death.
7.
Do not weld pipes or metal that are covered in combustible material or in
contact with combustible structure such as a wall. Only weld if the
covering can be safely removed.
a.
Follow all safety precautions and legal requirements before welding a
workpiece that contains Asbestos or attempting to remove the
Asbestos covering. This requires expert knowledge and equipment.
