S
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.
S
Clean, maintain, test, and repair equipment according to the instructions
in your equipment documentation.
S
Use only replacement parts that are designed for use with original
equipment. Contact your Nordson representative for parts information
and advice.
Grounding
WARNING:
Operating faulty electrostatic equipment is hazardous and can
cause electrocution, fire, or explosion. Make resistance checks part of your
periodic maintenance program. If you receive even a slight electrical shock
or notice static sparking or arcing, shut down all electrical or electrostatic
equipment immediately. Do not restart the equipment until the problem has
Grounding inside and around the booth openings must comply with
European Union harmonized norm requirements for Zone 20, Zone
21, or Zone 22, which ever Zone is applicable.
Refer to EN12981 and EN50177.
S
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.
S
Equipment to be grounded includes, but is not limited to, the floor of the
spray area, operator platforms, hoppers, photoeye supports, and
blow-off nozzles. Personnel working in the spray area must be
grounded.
S
There is a possible ignition potential from the charged human body.
Personnel standing on a painted surface, such as an 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.
S
Operators must maintain skin-to-handle 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.
S
Shut off electrostatic power supplies and ground gun electrodes before
making adjustments or cleaning powder spray guns.
S
Connect all disconnected equipment, ground cables, and wires after
servicing equipment.
