Know where emergency stop buttons, shutoff valves, and fire
extinguishers are located. If a fire starts in a spray booth,
immediately shut off the spray system and exhaust fans.
Clean, maintain, test, and repair equipment according to the
instructions in your equipment documentation.
Use only replacement parts that are designed for use with original
equipment. Contact your Nordson representative for parts
information and advice.
All work conducted inside the spray booth or within 1 m (3 ft) of booth
openings is considered within a Class 2, Division 1 or 2 Hazardous
location and must comply with NFPA 33, NFPA 70 (NEC articles 500,
502, and 516), and NFPA 77, latest conditions.
All electrically conductive objects in the spray areas shall be
electrically connected to ground with a resistance of not more than 1
megohm as measured with an instrument that applies at least 500
volts to the circuit being evaluated.
Equipment to be grounded includes, but is not limited to, the floor of
the spray area, operator’s platform, hoppers, photoeye supports, and
metal blow-off nozzles. Personnel working in the spray area must be
grounded.
There is a possible ignition potential from the charged human body.
Personnel standing on a painted surface, such as the operator
platform, or wearing non-conductive shoes, are not grounded.
Personnel must wear shoes with conductive soles or use a ground
strap to maintain a connection to ground when working with or around
electrostatic equipment.
Operators must maintain skin-to-metal contact between their hand
and the gun handle to prevent shocks while operating manual
electrostatic spray guns. If gloves must be worn, cut away the palm
or fingers, wear electrically conductive gloves, or wear a grounding
strap connected to the gun handle or other true earth ground.
