General Safety Warnings and Cautions

Table 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 as follows:

HM = Hot melt (melters, hoses, applicators, etc.)

PC = Process control

CA = Cold adhesive (dispensing pumps, pressurized container, and

applicators)

Table 1 General Safety Warnings and Cautions

Equipment

Type

Warning or Caution

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.

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.

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.

Equipment

Type

Warning or Caution

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.

WARNING: Risk of fire or explosion! Nordson cold 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 to the equipment.

General Safety Warnings and Cautions (contd)

Table 1 General Safety Warnings and Cautions (contd)

Warning or Caution

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.

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 MSDS supplied with the compound. Some cleaning

compounds can react unpredictably with hot melt or cold adhesive,

resulting in damage to the equipment.

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 handapplicator at yourself or others.

 Suspend dispensing handapplicators by their proper suspension point.
