AREA HAZARD SAFEGUARDS

Use of unsuitable solvents

Toxic Vapors

Compressed Air

The solvents 1,1,1-Trichlorethane
and Methylene Chloride can
chemically react with aluminum

used in paint spray guns, paint
pumps, etc. and cause an explo-

sion. These solvents can also
react with galvanized compo-

nents and cause corrosion and
weakening of parts.

Compressed air from this unit
may contain poisonous carbon

monoxide.
Certain sprayed materials such

as paints, weed killer, sand,
insecticides, etc., may be harmful

if used in a closed area or if
inhaled.

Compressed air may propel dirt,
metal shavings, etc. and result in

possible injury.

This hazard does not affect your compressor
outfit - but it may affect the equipment used
with the outfit. Read the label or data sheet

for the material you intend to spray. Equip-

ment containing aluminum or galvanized
parts that will come in contact with these sol-

vents, and that can contain pressure, must
not be used with these solvents. You must

either change the material, or use only
stainless steel spray equipment.

Never directly inhale the compressed air pro-
duced by this unit.

Be certain to read labels when spraying
paints or poisons.

Use a mask or respirator whenever there is a

chance that you might inhale anything that
you are spraying. Read all instructions so

that you know that your mask will protect you
from what you are spraying.

Never point any nozzle or sprayer toward a

person or any part of the body.
Always wear safety goggles orglasses when

spraying.
