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, applicators, 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 Applicators
NOTE: Adhesive dispensing applicators are referred to as “guns” in some
previous publications.
All electrical or mechanical devices that provide an activation signal to the
applicators, applicator solenoid valve(s), or the melter pump must be
disabled before work can be performed on or around an applicator that is
connected to a pressurized system.
1. Turn off or disconnect the applicator triggering device (pattern controller,
timer, PLC, etc.).
2. Disconnect the input signal wiring to the applicator solenoid valve(s).
3. Reduce the air pressure to the applicator solenoid valve(s) to zero; then
relieve the residual air pressure between the regulator and the applicator.

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, applicators, etc.)
PC = Process control
CA = Cold adhesive (dispensing pumps, pressurized container, and
applicators)
Table 1‐1General 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 SDS. 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
SDS 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 applicators 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.

Table 1‐1General Safety Warnings and Cautions (contd)
Equipment
Type Warning or Caution
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.
HM, PC
WARNING! Equipment starts automatically! Remote triggering devices
are used to control automatic hot melt applicators. Before working on
or near an operating applicator, disable the applicator's triggering
device and remove the air supply to the applicator's solenoid valve(s).
Failure to disable the applicator'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 has not been certified
for the ATEX directive or as nonincendive. In addition, this equipment
should not be used with solvent‐based adhesives that can create an
explosive atmosphere when processed. Refer to the SDS 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 to the equipment.
Safety 1-9
2018 Nordson Corporation Issued 4-15
Warning or Caution
Equipment
Type
HM
CAUTION! Hot surfaces! Avoid contact with the hot metal surfaces of
applicators, hoses, and certain components of the melter. If contact
can not be avoided, wear heat‐protective gloves and clothing when
working around heated equipment. Failure to avoid contact with hot
metal surfaces can result in personal injury.
HM
CAUTION! Some Nordson melters are specifically designed to
process polyurethane reactive (PUR) hot melt. Attempting to process
PUR in equipment not specifically designed for this purpose can
damage the equipment and cause premature reaction of the hot melt. If
you are unsure of the equipment's ability to process PUR, contact your
Nordson representative for assistance.
HM, CA
CAUTION! Before using any cleaning or flushing compound on or in
the equipment, read and comply with the manufacturer's instructions
and the SDS supplied with the compound. Some cleaning compounds
can react unpredictably with hot melt or cold adhesive, resulting in
damage to the equipment.
HM
CAUTION! Nordson hot melt equipment is factory tested with Nordson
Type R fluid that contains polyester adipate plasticizer. Certain hot melt
materials can react with Type R fluid and form a solid gum that can
clog the equipment. Before using the equipment, confirm that the hot
melt is compatible with Type R fluid.

Other Safety Precautions
Do not use an open flame to heat hot melt system components.
Check high pressure hoses daily for signs of excessive wear, damage, or
leaks.
Never point a dispensing handgun at yourself or others.
Suspend dispensing handguns by their proper suspension point.
First Aid
If molten hot melt comes in contact with your skin:
1. Do NOT attempt to remove the molten hot melt from your skin.
2. Immediately soak the affected area in clean, cold water until the hot melt
has cooled.
3. Do NOT attempt to remove the solidified hot melt from your skin.
4. In case of severe burns, treat for shock.
5. Seek expert medical attention immediately. Give the SDS for the hot melt
to the medical personnel providing treatment.
