FIRE OR EXPLOSION HAZARD
Static
is created by the high velocity flow of fluid
through the pump and hose. If every part of the
sprayldispensing equipment is not properly grounded, spark-
ing
may occur, and the system may become hazardous.
Sparking may also occur when plugging in or unplugging a
power supply cord. Sparks can ignite fumes from solvents and
the fluid being sprayedldispensed, dust particles and other
flammable substances, whether you are sprayingldispensing
indoors or outdoors, and can cause
a
fire or explosion and
serious bodily injury and property damage.
Do
not plug in or
unplug any power supply cords in the sprayldispensing area
when there is any chance of igniting fumes still in the air.
