• Provide bystanders with shields or helmets
fi tted with a #10 shade fi lter lens.
• Wear protective clothing. The intense light
of the cutting arc can burn the skin in much
the same way as the sun, even through
light-weight clothing. Wear dark clothing
of heavy material. The shirt worn should be
long sleeved and the collar kept buttoned to
protect chest and neck.
• Protect against REFLECTED ARC RAYS. Arc
rays can be refl ected off shiny surfaces such
as a glossy painted surface, aluminum,
stainless steel, and glass. It is possible for your
eyes to be injured by refl ected arc rays even
when wearing a protective helmet or shield.
If working with a refl ective surface behind
you, arc rays can bounce off the surface, then
off the fi lter lens on the inside of your helmet
or shield, then into your eyes. If a refl ective
background exists in your working area,
either remove it or cover it with something
non-fl ammable and non-refl ective. Refl ective
arc rays can also cause skin burn in addition
to eye injury.
FIRE HAZARDS
WARNING
FIRE OR EXPLOSION CAN CAUSE
DEATH, INJURY, AND PROPERTY
DAMAGE!
To reduce the risk of death, injury, or
property damage from fi re or explosion, read,
understand, and follow the following safety
instructions. In addition, make certain that
anyone else that uses this equipment, or is a
bystander in the working area, understands
and follows these safety instructions as well.
REMEMBER! Plasma Arc cutting by nature
produces sparks, hot spatter, molten metal
drops, hot slag, and hot metal parts that can
start fi res, burn skin, and damage eyes.
• Do not wear gloves or other clothing that
contains oil, grease, or other fl ammable
substances.
• Do not wear fl ammable hair preparations.
• Do not work in an area until it is checked and
cleared of combustible and/or fl ammable
materials. BE AWARE that sparks and slag can
fl y 35 feet and can pass through small cracks
and openings. If work and combustibles
cannot be separated by a minimum of 35
feet, protect against ignition with suitable,
snug-fi tting, fi re resistant, covers or shields.
• Do not cut on walls until checking for and
removing combustibles touching the other
side of the walls.
• Do not weld, cut, or perform other such
work on used barrels, drums, tanks, or other
containers that had contained a fl ammable or
toxic substance. The techniques for removing
fl ammable substance and vapors, to make a
used container safe for welding or cutting,
are quite complex and require special
education and training.
• Do not strike an arc on a compressed gas or
air cylinder or other pressure vessel. Doing
so will create a brittle area that can result in a
violent rupture immediately or at a later time
as a result of rough handling.
• Do not weld or cut in an area where the air
may contain fl ammable dust (such as grain
dust), gas, or liquid vapors (such as gasoline).
• Do not handle hot metal, such as the work
piece or electrode stubs, with bare hands.
• Wear leather gloves, heavy long sleeve
shirt, cuffl ess trousers, high-topped shoes,
helmet, and cap. As necessary, use additional
protective clothing such as leather jacket
or sleeves, fi re resistant leggings, or apron.
Hot sparks or metal can lodge in rolled up
sleeves, trouser cuff s, or pockets. Sleeves and
collars should be kept buttoned and pockets
eliminated from the shirt front.
• Have fi re extinguisher equipment handy
for immediate use! A portable chemical fi re
extinguisher, type ABC, is recommended.
• Wear ear plugs when workng overhead to
prevent spatter or slag from falling into ear.
• Make sure working area has a good, solid,
safe fl oor, preferably concrete or masonry,
not tiled, carpeted, or made of any other
fl ammable material.
• Protect fl ammable walls, ceilings, and fl oors
with heat resistant covers or shields.
• Check working area to make sure it is free
of sparks, glowing metal or slag, and fl ames
before leaving the working area.
