Under no circumstances should the housing of the plasma cutter be opened.
Always protect your eyes and face with a welding mask or safety visor.
Wear appropriate protective clothing such as a welding leather apron and sleeved gloves etc.
Avoid exposing skin as UV rays are produced by the arc.
Screen off the work place to protect others working nearby from UV rays, sparks or debris.
Metal materials with contaminated surfaces may generate toxic fumes. Ensure the surface is
clean before cutting. Avoid operating on materials cleaned with chlorinated solvents or near
such solvents.
Do not cut metal equipment that holds/contains flammable materials, gases or
liquid combustibles.
Zinc-plated or galvanized material should not be cut as the fumes created are highly toxic.
Do not use the plasma cutter in damp or wet conditions.
Do not use cables with worn insulation or loose connections.
Disconnect from the power supply before replacing electrodes.
Avoid direct contact with the cutting arc.
Do not use the plasma cutter to defrost piping.
Ensure the plasma cutter is placed on a level surface to prevent overturning.
Provide adequate ventilation or a means for removal of the cutting fumes produced (forced
circulation using a blower or fan).
Fumes
Toxic gases are given off during the arc / plasma cutting process, which may collect in the work
place or area if the ventilation is poor. Be alert at all times to the possibility of fume build-up.
In small or confined areas use a fume extractor.
Glare
The electric arc generated by the cutting torch process gives direct heat and ultraviolet
radiation. It is essential that the eyes of the operator and bystanders are protected from the
glare during welding.
ALWAYS USE A FACESHIELD OR WELDING HELMET FITTED WITH THE CORRECT GLASS
FILTER.
Heat
It is desiderable that welding gloves are worn whilst cutting. They will protect the hands from
ultra-violet radiation and direct heat of the arc.
OVERALLS should also be worn. They should be of type designed to be buttoned at the wrists
and the neck.
Dress
In addition to face shield, welding gloves and overalls, other types of protective clothing
should be worn when cutting. Additional protective clothing such as a leather apron, sock
protectors and a hat will all assist in reducing any injuries due to heat, sparks and slag
produced during cutting.
