Applications for laser equipment
The CO2 laser equipment described in this document is designed for marking material by
infrared radiation in an industrial environment. The equipment is a Class IV laser product and
it is therefore recommended that a laser safety officer is appointed and that the operator is
advised accordingly.
NOTE:
Use of laser equipment for applications other than those for which it was designed
constitutes misuse of the equipment. MARKEM-IMAJE will therefore accept no
liability in connection with any damage or injury whatsoever.
MARKEM-IMAJE will also accept no liability for any damage or injury occurring after
modifications have been made to the system without MARKEM-IMAJE's written
approval.
Do not use the laser beam to heat foodstuffs, as this could cause injury or produce
toxic vapours, fumes or substances.
It may also be hazardous to use the equipment on organic materials, such as wood or
plastic. Ensure that all peoplenel are fully aware of applicable safety instructions
before working on any material using a laser beam.
Recommended management procedures
Ensure that operators receive regular safety instructions at least once a year and make sure
that they read and understand the contents of this manual.
Ensure that operators have a copy of this safety information document readily available for
consultation.
Observe all current regulations regarding the prevention of accidents at the workplace.
Affix the correct warning labels and notices on the laser equipment
Ensure that access to the laser equipment is restricted to trained and authorized peoplenel.
Ensure that the area set aside for the laser equipment is clearly defined and marked.
Flammable gases, liquids or solids can ignite when irradiated by the leaser beam. Remove
this type of material from the area allocated for the laser equipment.
Some materials such as metal or plastic can give off toxic decomposition products when
subjected to the laser beam. Review hazards associated with material which is being
processed. Information can be obtained from professional organisations.
Arrange to have any object which could reflect the laser beam removed from the laser safety
area.
Ensure that the laser system is in a safe condition before starting work, paying particular
attention to the safety shields, beam generation devices and tip systems.

Installation
The printer must be installed in a well-ventilated place away from any source of heat, flame or
sparks.
The printer and print head must be secured with the attachment devices provided.
The printer installation on the production line must not generate any risks for people.
The operator's workstation must face the printer.
The equipment must be connected to an earthed single phase mains electricity supply, using
the lead supplied with the printer. The lead has a standard mains plug which must be easily
accessible at all times.
The electrical and pneumatic systems upstream from the printer must comply with applicable
standards.
In cases where the printer or a part of the printer is fitted to a support device, the device
concerned must be grounded.
Ground all conducting parts on or close to the printer which are not used as a voltage
reference (metal framework, protective covers, etc.)
Radiation hazards
The wavelength of the beam emitted from a CO2 laser is between 9.3 µm and 11.5 µm.
The light of the laser beam within the infrared part of the electromagnetic spectrum is not
visible to the naked eye.
MARKEM-IMAJE CO2 lasers emit powerful infrared radiation which, despite being invisible to
the eye, in many ways acts like sunlight.
Concentrated beams are sufficiently powerful to cut through certain materials, and the beam
is potentially hazardous even when it is not concentrated.
CO2 laser radiation can be absorbed by most dielectric substances, like water, biological
tissue, glass and plastic and is instantly absorbed by the first absorbent material with which it
enters into contact.
CO2 laser radiation can be reflected by smooth metal surfaces, even if they have been
darkened.
CO2 laser radiation can be concentrated using lenses to make it more effective for cutting or
marking applications. The laser beam disperses rapidly beyond the focal point causing the
energy density or beam intensity to become dissipated.
The laser opening is clearly marked with a label. Never expose the eye or the skin to direct or
indirect laser radiation.

Safety
A70622-D1
14/192
■ Eye protection
Since the CO2 laser beam is very strongly absorbed by water, the cornea and the
sclerotic coat are the main parts of the eye which are at risk from damage. They can
suffer irreversible defects and permanent scarring following direct or indirect exposure
to a CO2 laser beam. The severity of the damage to these parts of the eye depends on
the level of concentration or diffusion in the beam and on exposure time.
IMPORTANT:
Permanent eye damage can be caused if the laser radiation enters the eyeballs
directly or by reflection from a metal surface during procedures requiring access
to the laser emitter.
People must wear protective goggles suitable for use with carbon dioxide lasers
when using Class IV lasers.
Anyone not wearing appropriate eye protection must be kept out of the area or
room where the laser equipment is located.
The following precautions only apply to protection against CO2 laser radiation, with
wavelengths between 9.3 and 11.5 µm (microns):
All people working in the area where the laser equipment is operated must wear
protective goggles with side shields for use with CO2 laser radiation.
Plastic prescription glasses may only be used instead of goggles at the user's risk,
as they do not have protective side shields. N.B.: Glass can be shattered by a high-
power laser beam.
Contact lenses and half-moon reading glasses never provide sufficient protection.
Glazing providing protection against CO2 radiation generally protects people
passing behind the glass.
Never look directly at the carbon dioxide laser light source or at a laser light which
has been diffused on reflective surfaces.
The working area must be isolated by means of metal, acrylic or polycarbonate
panelling and have a lockable safety door.
The laser system must be de-activated automatically by an interlock system when
the safety door is opened. The door interlock circuit must be designed or
configured so that the operator is forced to take action before the circuit is re-
activated after the operator has opened and then closed the door.

■ Skin protection
Skin exposed to laser radiation may be subject to burns or cuts which can sometimes
cause permanent injury.
The following precautions only apply to protection against CO2 laser radiation, with
wavelengths between 9.3 and 11.5 µm (microns):
Do not place the hands or objects of any kind in the path of the CO2 laser beam.
The laser beam must never be operated without a target to absorb energy.
Metal objects reflect the CO2 laser beam. Darkened metal objects can also reflect
the laser beam. Matt or embossed objects diffuse the laser beam. Items which
absorb the laser beam heat up.
The laser must be halted immediately if an emergency occurs (laser-related or
otherwise). Situations requiring an emergency shut-down include:
- Shutter malfunction,
- Water leak in laser unit base,
- Fire,
- Incorrect use of laser,
- Use of laser without authorization
■ Protection against fire risks
Flammable objects can ignite when they come into contact with the laser beam.
A CO2laser can ignite most non-metallic materials.
Never operate the laser in the presence of flammable gases or liquids.
Never operate the laser in the presence of explosive materials.
Ensure that the laser installation includes an adequate safety interlock system.

Fume and vapour hazards
■ Fume hazards
The reactions produced by the laser system can lead to the emission of hazardous
particulates or gases. These by-products can be toxic. Ensure that all safety
instructions are observed before working on material with a laser beam. Also verify
compliance with health, safety and environmental requirements.
The laser system provides the user with a "hot" beam similar to a very fine blowtorch
flame. This beam can be used to heat or burn the surface of certain materials in a
controlled manner.
Some materials decompose chemically when they are heated and can emit dangerous
fumes in the form of gas or solid particles - examples include polyvinylchloride (PVC)
and polycarbonate.
Refer to documentation on the properties of these materials before working on them, or
ask for advice from manufacturer of the material concerned.
■ Extraction system
The use of an extraction system is recommended for removing fume emissions. Special
filters can be used to filter fumes which are present at the workplace. These filters must
be cleaned and/or replaced as indicated in the safety instructions. These operations
must be performed in accordance with local and national regulations for the protection
of the environment. Consult a company which specialises in these activities for advice
on the removal of fumes to eliminate the risk of contamination and to prevent hazards
for health and the environment.
The settings of the extractor installation are linked to each customer application.
Remember that the extractor is designed to be used to remove fume emissions, not to
be a dust cleaner. In any case, keep sure that no incandescent particle can be sucked,
and do not cut the hose (keep all the original length).
Do not attempt to use the laser beam to work on a material until you have
investigated and fully understood how it reacts to heat.
Employ a method which provides sufficient protection and allows safe removal of
the fumes produced by working with the laser.
If you want to mark plastic material, filter the vapours caused by the marking
operation downwards
If you want to mark PVC (polyvinylchloride) with a laser beam, a number of
precautions should be applied when removing fumes. The chemical reaction
generated by heating and the humidity in the air produces hydrochloric acid.
Hydrochloric acid is dangerous for both the operator and the laser system. Contact
a firm specializing in fume extraction to avoid any risk.

Safety
A70622-D1
17/192
Electrical hazards
Installation, servicing and repair work should be entrusted to Markem-Imaje-qualified people
or to electrical technicians following consultation with the Markem-Imaje after-sales dept. or
an authorized dealer.
Disconnect the equipment from the mains power supply before carrying out
any work which requires the removal or replacement of a part.
Never take off the laser covers. Removal of these covers exposes high voltage. Removal
of inner covers from the laser unit or from the optical assembly could allow the laser beam
to escape.
The area around the laser system must be kept dry.
The area around the laser system must remain well lit to allow people to work on the laser
equipment safely.
Never operate the laser if there is any indication that water is leaking from the system. Call
the nearest service centre.
Do not use the laser if the mains power supply cable is damaged or frayed.
The laser must be serviced and inspected at regular intervals in accordance with
MARKEM-IMAJE's recommendations.
Safety instructions
Markem-Imaje laser units incorporate various safety functions. It is necessary for the end
user to have access to these functions within a complete system installation to meet safety
standards. These functions are listed below:
■ Safety interlocks
Special tools must be used to open the internal parts of the laser's protective casing easily.
There are no parts inside the protective casing of the CO2 laser which can be operated by
the user, and there is no access panel with safety interlocks.
■ Remote interlocks
The system has two remote interlock systems. These systems consist of two separate
circuits which are used for locking and switching actions for a remote emergency shut-
down.
■ Warning light to indicate emission of laser radiation
This indicator light can be used to indicate possible emission of laser radiation for safety
purposes. The laser emission light is red and is located on the control panel at the bottom
of the laser.
A message is displayed on the control panel LCD screen if the indicator light fails when the
system is in use.

Safety
A70622-D1
18/192
■ Safety shutter
All MARKEM-IMAJE systems are fitted with a safety shutter operated by an
electromagnet. This allows the user to block or deflect the laser beam with a reflective
mechanical plate. There are two position sensors for the shutter open and closed position
which are used to monitor safety.
■ Emergency stop switch
The MARKEM-IMAJE system includes an emergency stop switch on the control panel.
This red push-button has spring-operated contacts and complies with electrical standards.
■ ON/OFF (0/I) switch
This switch is located at the back of the system. When the switch is in the OFF position,
power is shut off from the main parts of the system. Always switch the equipment off when
it is not in use.
■ Key-operated start/stop switches
The MARKEM-IMAJE system is fitted with two key-operated start/stop switches. The first
is used to supply power to the laser source and the second is for opening or closing the
laser beam shutter.
■ Manual restart
It must not be possible for the user to reset the system to restart the laser beam
automatically if the mains power supply fails or if an interlock device is activated. This
requirement means that there has to be a safety interlock on the cover of a protective
enclosure. The installed laser belongs to Class IV when the covers are opened.
■ Warning label
Warning labels must be affixed to certain parts of the system. These labels indicate the
conditions which could expose the user to laser radiation.
Apart from the laser symbol itself which does not include any wording, all labels are to be
written in the language indicated by the user.
