no objects are within the sparking distance.
Explosion Hazard –
Incompatible Materials
Halogenated hydrocarbon
solvents 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.
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.
