Fire Safety
1602369-05
To avoid a fire or explosion, follow these instructions.
• Ground all conductive equipment. Use only grounded air and fluid hoses. Check
equipment and workpiece grounding devices regularly. Resistance to ground must not
exceed one megohm.
• Shut down all equipment immediately if you notice static sparking or arcing. Do not
restart the equipment until the cause has been identified and corrected.
• Do not smoke, weld, grind, or use open flames where flammable materials are being
used or stored. Do not heat materials to temperatures above those recommended
by the manufacturer. Make sure heat monitoring and limiting devices are working
properly.
• Provide adequate ventilation to prevent dangerous concentrations of volatile particles
or vapors. Refer to local codes or your material SDS for guidance.
• Do not disconnect live electrical circuits when working with flammable materials. Shut
off power at a disconnect switch first to prevent sparking.
• 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.
• Shut off electrostatic power and ground the charging system before adjusting,
cleaning, or repairing electrostatic equipment.
• 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.
Halogenated Hydrocarbon Solvent Hazards
Do not use halogenated hydrocarbon solvents in a pressurized system that contains
aluminum components. Under pressure, these solvents can react with aluminum and
explode, causing injury, death, or property damage. Halogenated hydrocarbon solvents
contain one or more of the following elements:
Element
Symbol
Fluorine
F
Chlorine
Cl
Bromine
Br
Iodine
I
Check your material SDS or contact your material supplier for more information. If you
must use halogenated hydrocarbon solvents, contact your Nordson representative for
information about compatible Nordson components.
