Toxic Substances
Spray Area
Certain material may be harmful
if inhaled, or if there is contact
with the skin.
Explosion Hazard –
Incompatible Materials
Halogenated hydrocarbon sol-
vents for example: methylene
chloride and 1,1,1,-Trichloroethane are not chemically compatible with the aluminum that
might be used in many system
components. The chemical
reaction caused by these solvents reacting with aluminum
can become violent and lead to
an equipment explosion.
Follow the requirements of the Material Safety
Data Sheet supplied by coating material manufacturer.
Adequate exhaust must be provided to keep the
air free of accumulations of toxic materials.
Use a mask or respirator whenever there is a
chance of inhaling sprayed materials. The mask
must be compatible with the material being
sprayed and its concentration. Equipment must
be as prescribed by an industrial hygienist or
safety expert, and be NIOSH approved.
Aluminum is widely used in other spray application equipment - such as material pumps,
regulators, triggering valves, etc. Halogenated
hydrocarbon solvents must never be used with
aluminum equipment during spraying, ushing,
or cleaning. Read the label or data sheet for the
material you intend to spray. If in doubt as to
whether or not a coating or cleaning material is
compatible, contact your coating supplier. Any
other type of solvent may be used with aluminum
equipment.
