• To prevent an arc flash from being creat-
ed on contact do not allow the uninsulat-
ed portion of the cutting torch to touch
the ground clamp or grounded work.
• Provide bystanders with shields or
helmets fitted with a #8 shade filter 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 reflected off shiny surfaces
such as a glossy painted surface,
aluminum, stainless steel, and glass. It is
possible for your eyes to be injured by
reflected arc rays even when wearing a
protective helmet or shield. If working with
a reflective surface behind you, arc rays
can bounce off the surface, then off the fil-
ter lens on the inside of your helmet or
shield, then into your eyes. If a reflective
background exists in your work area, either
remove it or cover it with something non-
flammable and non-reflective. Reflective
arc rays can also cause skin burn in addi-
tion to eye injury.
FIRE HAZARDS
WARNING
FIRE OR EXPLOSION CAN CAUSE
DEATH, INJURY, AND PROPERTY DAM-
AGE! To reduce the risk of death, injury, or
property damage from fire 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 work 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 fires, burn skin, and damage eyes.
• Do not wear gloves or other clothing that
contains oil, grease, or other
flammable substances.
• Do not wear flammable hair
preparations.
• Do not work in an area until it is checked
and cleared of combustible and/or
flammable materials. BE AWARE that
sparks and slag can fly 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-fitting, fire resistant, covers or
shields.
• Do not plasma 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
flammable or toxic substance. The
techniques for removing flammable sub-
stance 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 flammable 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, cuffless trousers, high-topped
shoes, helmet, and cap. As necessary,
use additional protective clothing such as
leather jacket or sleeves, fire resistant
leggings, or apron. Hot sparks or metal
can lodge in rolled up sleeves, trouser
cuffs, or pockets. Sleeves and collars
should be kept buttoned and pockets
eliminated from the shirt front.
• Have fire extinguisher equipment handy
for immediate use! A portable chemical
fire extinguisher, type ABC, is
recommended.
• Wear ear plugs when working overhead
to prevent spatter or slag from falling
into ear.
• Make sure work area has a good, solid,
