Equipment Safety Information
This equipment safety information is applicable to the following types of
Nordson equipment:
Shot melt and cold adhesive application equipment and all related
accessories
Spattern controllers, timers, detection and verification systems, and all
other optional process control devices
Equipment Shutdown
To safely complete many of the procedures described in this document, the
equipment must first be shut down. The level of shut down required varies
by the type of equipment in use and the procedure being completed. If
required, shut down instructions are specified at the start of the procedure.
The levels of shut down are:
Relieving System Hydraulic Pressure
Completely relieve system hydraulic pressure before breaking any hydraulic
connection or seal. Refer to the melter-specific product manual for
instructions on relieving system hydraulic pressure.
De-energizing the System
Isolate the system (melter, hoses, guns, and optional devices) from all
power sources before accessing any unprotected high-voltage wiring or
connection point.
1. Turn off the equipment and all auxiliary devices connected to the
equipment (system).
2. To prevent the equipment from being accidentally energized, lock and
tag the disconnect switch(es) or circuit breaker(s) that provide input
electrical power to the equipment and optional devices.
NOTE: Government regulations and industry standards dictate specific
requirements for the isolation of hazardous energy sources. Refer to
the appropriate regulation or standard.

Disabling the Guns
All electrical or mechanical devices that provide an activation signal to the
guns, gun solenoid valve(s), or the melter pump must be disabled before
work can be performed on or around a gun that is connected to a
pressurized system.
1. Turn off or disconnect the gun triggering device (pattern controller, timer,
PLC, etc.).
2. Disconnect the input signal wiring to the gun solenoid valve(s).
3. Reduce the air pressure to the gun solenoid valve(s) to zero; then
relieve the residual air pressure between the regulator and the gun.

General Safety Warnings and Cautions
Table 1-1 contains the general safety warnings and cautions that apply to
Nordson hot melt and cold adhesive equipment. Review the table and
carefully read all of the warnings or cautions that apply to the type of
equipment described in this manual.
Equipment types are designated in Table 1-1 as follows:
HM = Hot melt (melters, hoses, guns, etc.)
PC = Process control
CA = Cold adhesive (dispensing pumps, pressurized container, and
guns)
Table 1-1 General Safety Warnings and Cautions
Equipment
Type Warning or Caution
HM
WARNING: Hazardous vapors! Before processing any polyurethane
reactive (PUR) hot melt or solvent-based material through a
compatible Nordson melter, read and comply with the material’s
MSDS. Ensure that the material’s processing temperature and
flashpoints will not be exceeded and that all requirements for safe
handling, ventilation, first aid, and personal protective equipment are
met. Failure to comply with MSDS requirements can cause personal
injury, including death.
HM
WARNING: Reactive material! Never clean any aluminum component
or flush Nordson equipment with halogenated hydrocarbon fluids.
Nordson melters and guns contain aluminum components that may
react violently with halogenated hydrocarbons. The use of
halogenated hydrocarbon compounds in Nordson equipment can
cause personal injury, including death.
HM, CA
WARNING: System pressurized! Relieve system hydraulic pressure
before breaking any hydraulic connection or seal. Failure to relieve
the system hydraulic pressure can result in the uncontrolled release of
hot melt or cold adhesive, causing personal injury.
HM
WARNING: Molten material! Wear eye or face protection, clothing
that protects exposed skin, and heat-protective gloves when servicing
equipment that contains molten hot melt. Even when solidified, hot
melt can still cause burns. Failure to wear appropriate personal
protective equipment can result in personal injury.

General Safety Warnings and Cautions (contd)
Table 1-1 General Safety Warnings and Cautions (contd)
Equipment
Type Warning or Caution
HM, PC
WARNING: Equipment starts automatically! Remote triggering
devices are used to control automatic hot melt guns. Before working
on or near an operating gun, disable the gun’s triggering device and
remove the air supply to the gun’s solenoid valve(s). Failure to
disable the gun’s triggering device and remove the supply of air to the
solenoid valve(s) can result in personal injury.
HM, CA, PC
WARNING: Risk of electrocution! Even when switched off and
electrically isolated at the disconnect switch or circuit breaker, the
equipment may still be connected to energized auxiliary devices.
De-energize and electrically isolate all auxiliary devices before
servicing the equipment. Failure to properly isolate electrical power to
auxiliary equipment before servicing the equipment can result in
personal injury, including death.
HM, CA, PC
WARNING: Risk of fire or explosion! Nordson adhesive equipment is
not rated for use in explosive environments and should not be used
with solvent-based adhesives that can create an explosive
atmosphere when processed. Refer to the MSDS for the adhesive to
determine its processing characteristics and limitations. The use of
incompatible solvent-based adhesives or the improper processing of
solvent-based adhesives can result in personal injury, including death.
HM, CA, PC
WARNING: Allow only personnel with appropriate training and
experience to operate or service the equipment. The use of untrained
or inexperienced personnel to operate or service the equipment can
result in injury, including death, to themselves and others and can
damage the equipment.
