Important Safety Precautions
OPERATION AND MAINTENANCE OF PLASMA ARC EQUIPMENT CAN BE DANGEROUS TO YOUR HEALTH.
Plasma arc cutting produces intense electric and magnetic emissions that may interfere with the
proper function of cardiac pacemakers, hearing aids, or other electronic health equipment.
Persons who work near plasma arc cutting applications should consult their medical health
qualied technician and the manufacturer of the health equipment to deter- mine whether a
hazard exists.
To prevent possible injury, read, understand and follow all warnings, safety precautions and
instructions before using the equipment.
GASES AND FUMES
Gases and fumes produced during the plasma cutting process can be dangerous and hazardous to
your health.
Keep all fumes and gases from the breathing area. Keep your head out of the cutting fume plume.
Use an air-supplied respirator if ventilation is not adequate to remove all fumes and gases.
The kinds of fumes and gases from the plasma arc depend on the kind of metal being used,
coatings on the metal, and the different processes.
Use special equipment, such as water or down draft cutting tables, to capture fumes and gases.
Do not use the plasma torch in an area where combustible or explosive gases or materials are
located.
Phosgene, a toxic gas, is generated from the vapors of chlorinated solvents and cleansers.
Remove all sources of these vapors.
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 ammable material in the workplace. Any material that cannot
be removed must be protected.
Ventilate all ammable or explosive vapors from the workplace.
Do not cut or weld on containers that may have held combustibles.
Provide a re watch when working in an area where re hazards may exist.
Hydrogen gas may be formed and trapped under aluminum workpieces 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.
PLASMA ARC RAYS
Plasma Arc Rays can injure your eyes and burn your skin. The plasma arc process produces very bright
ultra violet and infrared light. These arc rays will damage your eyes and burn your skin if you are not
properly protected.
To protect your eyes, always wear a cutting helmet or shield. Also always wear safety glasses with
side shields, goggles or other protective eye wear.
Wear cutting gloves and suitable clothing to protect your skin from the arc rays and sparks.
Keep helmet and safety glasses in good condition. Replace lenses when cracked, chipped or
dirty.
.
Protect others in the work area from the arc rays. Use protective booths, screens or shields.
