Qualified Personnel
Equipment owners are responsible for making sure
that Nordson equipment is installed, operated, and
serviced by qualified personnel. Qualified
personnel are those employees or contractors who
are trained to safely perform their assigned tasks.
They are familiar with all relevant safety rules and
regulations and are physically capable of
performing their assigned tasks.
Intended Use
Nordson ultraviolet (UV) equipment is intended
specifically for integration into other machines and
should NOT be operated as a standalone system
or without appropriate safety guarding, shielding,
and interlocks. It is the responsibility of the
integrator and end user to ensure that the final
assembly fulfills all necessary legislation and is
completely safe before operation.
This equipment is designed for the accelerated
curing of UV inks, adhesives, and coatings. Do not
use this equipment to cure alternative materials
unless approved by the material supplier.
The equipment is not flame or explosion proof and
is not designed for use in hazardous areas.
Use of Nordson equipment in ways other than
those described in the documentation supplied with
the equipment may result in injury to persons or
damage to property.
Some examples of unintended use of equipment
include:
Susing incompatible materials
Smaking unauthorized modifications
Sremoving or bypassing safety guards, shielding,
or interlocks
Susing incompatible or damaged parts
Susing unapproved auxiliary equipment
Soperating equipment in excess of maximum
ratings
Susing equipment in hazardous areas
Regulations and
Approvals
Make sure all equipment is rated and approved for
the environment in which it is used. Any approvals
obtained for Nordson equipment will be voided if
instructions for installation, operation, and service
are not followed.
Currently there are two organizations that set
recommended guidelines for exposure to
occupational microwave radiation exposure, OSHA
(U.S. Department of labor, Occupational Safety and
Health Administration −Directive 29cfr 1910.97)
and ANSI (American National Standards Institute −
Directive C95.1−1982). The ANSI directive, which
is more stringent and most commonly referred to,
states that individuals should not be exposed to
microwave radiation levels above 5 mW/cm2at
2.45 GHz on a continuous basis.

Personal Safety
To prevent injury follow these instructions.
SDo not operate or service equipment unless you
are qualified.
SDo not operate equipment unless safety
guards, light shields, doors, and/or covers are
intact and automatic interlocks are operating
properly. Do not bypass or disarm any safety
devices.
SKeep clear of moving equipment. Before
adjusting or servicing any moving equipment,
shut off the power supply and wait until the
equipment comes to a complete stop. Lock out
power and secure the equipment to prevent
unexpected movement.
SObtain and read Material Safety Data Sheets
(MSDS) for all materials used. Follow the
manufacturer’s instructions for safe handling
and use of materials. Always use
recommended personal protection devices.
SMake sure the UV area is adequately
ventilated.
SThe UV equipment runs at extremely high
temperatures. Do not touch the UV lamphead
face during operation or immediately after
shutting off the equipment.
STo prevent injury, be aware of less-obvious
dangers in the workplace that often cannot be
completely eliminated, such as hot surfaces,
sharp edges, energized electrical circuits, and
moving parts that cannot be enclosed or
otherwise guarded for practical reasons.
SAlways wear safety glasses that offer UV
protection.
SNever expose any part of the body to direct or
indirect UV light.
Ultraviolet Radiation
WARNING: Ultraviolet light is a form of
electromagnetic radiation and can be
harmful if exposure exceeds recommended
levels. Protect eyes and skin from direct
exposure to UV light. All equipment or
areas where UV light is used must be
adequately guarded, shielded, and
interlocked to prevent accidental exposure.
Ultraviolet light is not capable of penetrating into
the body and interacting with internal tissues and
organs.
The National Institute for Occupational Safety and
Health (NIOSH) document Criteria for
Recommended Standard... Occupational Exposure
to Ultraviolet Radiation (PB214 268) establishes
guidelines for safe use.
See Figure 1-2. Ultraviolet light is divided into
wavelength bands A, B, C, and V along with
vacuum UV. Although values for wavelength bands
will vary depending on the source, the following
ranges may be used as a guide.
SVacuum UV (100−200 nanometers) −absorbed
by air and poses no danger to humans.
SUV-A (315−400 nanometers) −represents the
largest portion of UV energy and is most
responsible for human skin aging and increased
pigmentation. UV−A is at the lower limit of
sensitivity to the human eye. Referred to as far
UV.
SUV-B (280−315 nanometers) −most
responsible for reddening and burning of the
skin and damage to the eyes.
SUV-C (200−280 nanometers) −filtered by
ozone. Referred to as near UV.
SUV-V (400−450 nanometers) – visible UV

It is very important that all precautions are taken to
prevent all UV light, whether direct or indirect, from
escaping the curing area. Exposure to UV light can
be harmful to both eyes and skin. Use the
following table to determine the permissible
exposure time to UV light on unprotected eyes or
skin.

First Aid
Store-bought creams, lotions, or aloe can be
applied to affected areas of the skin. Seek
immediate medical attention for skin burns and
direct UV exposure to the eyes.
Microwave Radiation
The lamp system utilizes high powered RF
microwave energy generated by a
magnetron to provide power to the UV
lamp. This technology is identical to that of
residential microwave ovens and like these
ovens can be dangerous if misused. The
lamp system is safe provided that the RF
screen and gasketing are intact. Any
damage such as rips or holes in the screen
may cause leakage of dangerous amounts
of microwave radiation. The power to the
lamp is interlocked to the RF detector and
will shut down if microwave leakage in
excess of 2 mW/cm2is detected. Any
excessive leakage will cause the system to
shutdown and the RF Detector fault will
illuminate on the front of the power supply.

Safety 1-5
Part 1074166-02
E2018 Nordson Corporation
Ozone Gas
Ozone (O3) is a colorless gas that is generated by
the reaction of short-wave UV light (around
200−220 nanometers) with air, and it occurs
whenever high-energy electrical discharge is
present.
Ozone readily reverts to breathable oxygen when
mixed with atmospheric air. Ozone should be
removed from the UV source via a sealed duct and
discharged to atmosphere according to local
regulations. The discharge location should be
away from pedestrian walkways and window
openings and should be well above the average
human breathing height for the area.
Regular ozone checks should be carried out every
three months using an ozone meter.
Recommended levels of ozone in the atmosphere
of a factory should not exceed 0.1 parts per
million (PPM). This level is easily obtainable if
factory recommended exhaust rates are followed.
Ozone has a very distinct, strong odor even at low
levels. Immediate ozone checks should be made if
an operator can smell ozone. Most people can
smell ozone at about one third the maximum
allowable 0.1 PPM level.
Ozone exposure will cause headaches and fatigue.
It will also irritate the mouth and throat.
Overexposure can lead to respiratory infections.
If ozone is detected,
1. Shut down the UV system.
2. Check exhaust ducting for leaks.
3. Check the operator working area with an ozone
meter.
If a person is overcome by ozone,
SMove the individual to a warm uncontaminated
atmosphere and loosen tight clothing at the
neck and waist.
SKeep the individual at rest.
SIf the person has difficulty breathing, oxygen
may be administered provided that suitable
apparatus and a trained operator are available.
SIf breathing is weak or has ceased, artificial
respiration should be started.
SSeek medical assistance.
High Temperature
UV curing systems generally run at
extremely high temperatures. A sudden
shock from touching a high temperature
surface might cause an operator to jump or
take his attention away from other potential
hazards.
When shutting down UV equipment for
maintenance, allow the equipment to cool before
beginning work, or wear protective gloves and
clothing to prevent burns.
High Voltage
The UV curing equipment operates at high voltages
up to 5000 Vdc. The system uses high-voltage,
self-discharging capacitors. Once power to the
power supply is shut off, the capacitors need
120 to 130 seconds to discharge.
If any electrical faults develop, the operator should:
1. Switch the equipment off immediately.
2. Make no attempt to service the equipment.
3. Call a qualified electrician, trained to service
this type of equipment.

Mercury Bulbs (Lamps)
The bulbs used in UV lamp systems contain
mercury under medium pressure. Mercury is a
toxic substance and must not be ingested or come
into direct contact with the skin. Under normal UV
operating conditions, mercury presents no hazard
as it is completely contained in the sealed quartz
tube of the bulb; however, it is strongly
recommended that protective gloves and eye
protection be worn when handling UV bulbs.
These precautions should be followed when
disposing of UV bulbs:
SPlace the bulb in a rigid protective carton.
SDispose of used bulbs through a local mercury
recycling center.
SWash your hands if a bulb breaks: mercury
could come into contact with your skin.
SDo not store or handle bulbs near food or
beverages.
SNordson Corporation will dispose of UV bulbs
free of charge provided the customer covers all
shipping costs associated with returning the
bulbs. For bulb disposal, please clearly mark
on the all bulb containers AND shipping
packages BULBS FOR DISPOSAL ONLY
Bulbs should be shipped to:
Primarc
Bulb Disposal Department

Easton, Pennsylvania 18045
UV Curable Inks and
Products
Some materials used in UV curable inks,
adhesives, and varnishes are toxic. Before
handling them, read the Material Safety Data
Sheets provided by the manufacturer, use the
recommended personal safety equipment, and
follow the recommended procedures for safe use
and disposal.
Fire Safety
Under proper operating conditions, the surface
temperature of the bulb is anywhere between
700−900 _C (1300−1700 _F), and the vapor gas
inside the bulb is several thousand degrees
Fahrenheit.
Any form of flammable material (such as paper, lint,
powder, or dirt) trapped under the lamp, within the
lamp housing or in the lamp’s vicinity, will result in
an increased risk of fire.
To avoid a fire or explosion, follow these
instructions.
SKnow where emergency stop buttons, shut-off
valves, and fire extinguishers are located.
SClean, maintain, test, and repair equipment
according to the instructions in this manual.
SAlways keep a fire extinguisher approved for
electrical equipment near the unit.
Should a fire occur, the operator must:
1. Switch the equipment off immediately.
2. If possible, put out the fire with a fire
extinguisher.
Action in the Event of a
Malfunction
If a system or any equipment in a system
malfunctions, shut off the system immediately and
perform the following steps:
1. Disconnect and lock out system electrical
power.
2. Identify the reason for the malfunction and
correct it before restarting the system.
