ELECTRIC SHOCK
Electric Shock can injure or kill. The plasma arc process uses and produces high voltage electrical
energy. This electric energy can cause severe or fatal shock to the operator or others in the workplace.
Never touch any parts that are electrically “live” or “hot.”
Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the cutting
circuit.
Repair or replace all worn or damaged parts.
Extra care must be taken when the workplace is moist or damp.
Disconnect power source before performing any service or repairs.
Read and follow all the instructions in the Operating Manual.
FIRE AND EXPLOSION
Fire and explosion can be caused by hot slag, sparks, or the plasma arc.
Be sure there is no combustible or flammable material in the workplace. Any material that cannot be
removed must be protected.
Ventilate all flammable or explosive vapors from the workplace.
Do not cut or weld on containers that may have held combustibles.
Provide a fire watch when working in an area where fire hazards may exist.
Hydrogen gas may be formed and trapped under aluminum work pieces when they are cut
underwater or while using a water table. DO NOT cut aluminum alloys underwater or on a water
table unless the hydrogen gas can be eliminated or dissipated. Trapped hydrogen gas that is ignited
will cause an explosion.
NOISE
Noise can cause permanent hearing loss. Plasma arc processes can cause noise levels to exceed safe
limits. You must protect your ears from loud noise to prevent permanent loss of hearing.
To protect your hearing from loud noise, wear protective ear plugs and/or ear muffs. Protect others
in the workplace.
Noise levels should be measured to be sure the decibels (sound) do not exceed safe levels.
