17. Maintain good ventilation of the louvers on this equipment. Good
ventilation is of critical importance for the normal performance and
service life of this equipment.
FIRE AND EXPLOSION PRECAUTIONS
Arc welding can produce sparks, hot slag or spatter, molten metal
drops and hot metal parts that can start fires.
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 plasma
cutting machine. Hot debris ejected during welding can land at a
considerable distance away. Solid floors of concrete or masonry is the
preferred working surface.
1.1 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.
1.2 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.
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.
