wearing of personal protective equipment. Direct exposure of theeye to the invisible laser beam must be avoided. At all times, proper
eye-wear must be worn and maintained according to PersonalProtection Equipment at Work regulations.

https://www.nktphotonics.com/lasers-fibers/support/certificatesand-approvals• Compulsory regulations also require the issuing and/or wearing of
personal protective equipment. The necessity of reading the laser’s
documentation applies especially to persons working only
occasionally with the laser.

Safety Instructions Governing SpecificOperational Phases• Use protective equipment, wherever required by the circumstancesor by law.

Precautions

Take the necessary precautions to ensure that the laser is used only
when in a safe and reliable state. In the event of malfunctions, disable
the laser device immediately and unplug its electrical power. Have any
defects rectified immediately.

Caution: Servicing the Laser:• There are no user serviceable components inside the laser. In caseof malfunction, NKT Photonics should be consulted.

Before starting the laser, prepare a site specific Risk Assessment toensure no persons are at risk. Inform operating personnel before
beginning special operations, and appoint a person to supervise theactivities. Ensure that the user operation area is adequately secured.

• The unit is sealed with a “WARRANTY VOID IF REMOVED” label andit is thus strictly prohibited to remove the chassis cover.
Caution: Storage:• If required, the laser should be stored in a dry and cool place (1520°C).

Specific Safety Aspects• The optical output should be protected using the mechanicalshutter on the front panel of the chassis.

•Physical hazards related to the system. See the following
section: Physical Hazards.

•Protection of the system users against physical hazards. SeeSection Personnel Safety.

•Proactive measures against these hazards. See the followingsection: Constructive Safety Features.

Specific safety aspects are:

• Avoid exposing the unit to vibrations or mechanical shock.
Caution: Chassis Cleaning• To clean the chassis, disconnect the power source and use a softand damp cloth. Do not use solvents or similar cleaning agents on
the chassis or any other parts of the laser.

Within this classification, the laser is a class 4 laser, and is a potential
hazard to the human operator. The class 4 laser beam is also classified
as a potential fire hazard. Direct radiation from Class 4 products are ahazard to eyes and skin. Precautions include eye and skin protection,

Caution: Emergency Response:• In the event of an emergency or accident, make sure to have a2

remote interlocks and warning labels.

Never look directly into any laser beam.

Physical Hazards

Avoid indirect viewing of direct or reflected laser radiation. Specularand diffuse reflections (from reflective surfaces) can be as dangerous
as the direct laser beam. Never view the beam directly through optical
instruments.

Warning: The laser beam is dangerous to the eyes and skin. The
dangers include:•Direct radiation as it leaves the laser.

•Radiation reflected from a surface.

•

Diffused radiation originated from a scattered reflection.

Take precautions to ensure that there are no reflecting objects in thepath of the laser beam.
Do not deviate from standard operating procedures when working
with class 4 and class 4 laser equipment.
Use lasers only in approved applications and locations. Take
adequate precautions to prevent unauthorized personnel fromentering the area where a class 4 laser is operating. Do not use lasers
around untrained personnel. Ensure that all personnel in the area
observe proper safety precautions.

LightIn case of exposure, the laser may provide laser radiation with power
levels up to 10 watts.. The laser’s emissions consists of a wide band of
wavelengths from 300 to 2700 nm. The output is a collimated beamfrom the output aperture on the collimator. Despite the non-ionizing
nature of the operating wavelengths, damage can still occur to living
tissue as a result of heat produced during radiation absorption or via
multi-photon absorption. Suitable beam dumps must be used at all
times when the laser is operating.

Report all incidents of exposure to your supervisor.
Clearly display warning signs indicating the laser enclosed area withan additional warning light outside the door.

In general, the maximum permissible radiation exposure for the skin isseveral times greater than for the eye. Safety measures with regard tothe radiation hazard are therefore mainly focused on dangers for theeye. Not only is the direct laser beam hazardous, but uncheckedreflections of laser light also constitutes a potential hazard.

Adhere to local and national regulations governing the safe use oflasers.
Be aware that maintenance of eyewear includes, but not limited to:inspection, cleaning, testing and training in use. Maintenance should
only be performed by competent personnel.

Personnel Safety

Skin Protection

Personnel Protection

Warning:

Warning:

Potential skin burns: if the laser beam is kept motionless for a long
period it can burn exposed skin. Only use the laser in accordance withits designated use. Safety interlocks are only to be overruled byauthorized personnel.

Risk of serious injury: Always wear wavelength specific laser safety
glasses when there is a chance of exposure to radiation from the laser.
The filter in protective eyewear provides protection for only a narrow
band of wavelengths. Ensure you are wearing the appropriate
protective eyewear for the laser device in question. Check with yourLaser Safety Officer or other safety personnel for guidance in selecting
the appropriate eyewear.

Although the skin can withstand considerably higher radiation
intensity than the eyes, tissue may be burned to a greater or lesser
degree, depending on the radiation time and the irradiation intensity.

For protective eyewear, the American National Standards Institute(ANSI) standard for the safe use of lasers requires that a set ofprotective eyewear blocking the appropriate laser wavelength should
be worn while operating or servicing class 4 lasers.

Avoid contact between the skin and the beam. Reflections of thebeam may be as dangerous as the beam itself. Wear appropriate
protective clothing to protect the skin whenever necessary.
Fire Protection

Clearly label safety eyewear with their optical density and their
specified wavelength protection. To avoid confusion, laser safety
eyewear should be kept separate from any other safety eyewear andpersonal protective equipment.

Warning:Fire hazards: Class 4 lasers are potential fire hazards. The laser beam
can cause flammable materials to ignite or explode. Always keep a fire
extinguisher in the laser area in case a fire occurs.

Using the wrong type of safety eyewear is dangerous. It can be moredangerous to have improper eyewear and a false sense of security
than to have no eyewear and take precautions based on the absenceof protection. Even if you are wearing protective eyewear, never lookdirectly into the beam; intense laser radiation is capable of destroying
the protective filter.

Because of the high output power from the class 4 laser, a wide rangeof materials can be set on fire. Therefore, take appropriate fire
prevention measures when the beam path is open:
Combustible materials may be ignited by the laser beam or byelectrical components inside the laser system. Flammable items mustbe isolated from the laser beam and from the laser system.

Eye Protection
Warning: Warning:
Potential eye burns: Only use the laser in accordance with its
designated use.

Paper (circuit diagrams, leaflets, or even posters on the wall), curtains
that are not coated with fire retardant, wooden panels or similarmaterials can be easily set on fire by direct or reflected laser radiation.

The following guidelines describe some of the actions necessary to
avoid injury caused by the laser beam. Always follow these guidelines
and take additional precautions if necessary.

Use only beam stops made of non-flammable materials (notasbestos!).

When eyewear is necessary, make sure it has the proper opticaldensity for the laser wavelength.

Many fluids and solvents (e.g. cleaning agents used for maintenance)
are combustible. The intense beam of the laser can ignite vapors fromthese materials. Prevent the laser beam from contacting flammablematerials used in the laser area.

All other personnel in the vicinity of the laser must wear protective
eyewear.

Move containers of flammable materials as far from the laser system
as possible and shield them from the beam with opaque materials.
Never place these solutions and vapors in the beam path or near thesystem.

Permit only qualified personnel to operate the laser.
