Pressure Relief Procedure
Pails
• Solvent and oil/based fluids:
follow local code. Use only
conductive metal pails, placed on
a grounded surface such as
concrete.
• Do not place pail on a
nonconductive surface such as
paper or cardboard which
interrupts grounding continuity.
• Grounding a metal pail: connect a
ground wire to the pail by clamping
one end to pail and other end to a
true earth ground such as a water
pipe.
• To maintain grounding
continuity when flushing or
relieving pressure: hold metal
part of spray gun firmly to side
of a grounded metal pail. Then
trigger gun.
