Spray Area

Explosion

Improper or inadequate operation and

maintenance procedures may cause an

explosion.
Protection against inadvertent arcing that is

capable of causing fire or explosion is lost if

any safety interlocks are disabled during op-

eration. Frequent power supply shutdown

indicates a problem in the system requiring

correction.

Follow These Guidelines

Electrostatic arcing MUST be prevented.

All electrical equipment must be located outside Class

I or II, Division 1 or 2 hazardous areas, in accordance

with NFPA 33, 2009 Edition.

Test only in areas free of flammable or combustible

materials.

The current overload sensitivity (if equipped) MUST

be set as described in corresponding section of the

equipment manual. Protection against inadvertent

arcing that is capable of causing fire or explosion is lost

if the current overload sensitivity is not properly set.

Frequent power shutdown indicates a problem with the

system which requires correction.

Always turn the control panel off prior to flushing, clean-

ing, or working on spray system equipment.

Ensure that the control panel is interlocked with the

ventilation system and conveyor in accordance with

NFPA 33, 2009 Edition.

Have fire extinguishing equipment readily available and

tested periodically.

Explosion - Incompatible Materials

Halogenated hydrocarbon solvents for

example: methylene chloride and 1,1,1,-Tri-

chloroethane 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.

Spray Area

Follow These Guidelines

Aluminum is widely used in other spray application

equipment - such as material pumps, regulators, trig-

gering valves, etc. Halogenated hydrocarbon solvents

must never be used with aluminum equipment during

spraying, flushing, 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 com-

patible, contact your coating supplier. Any other type of

solvent may be used with aluminum equipment.
