2 GENERAL SAFETY INFORMATION
2.5
Required training and instruction of operating personnel
The deflection unit is designed exclusively for use in an industrial environment.
Start-up, operation, installation, maintenance and repairs may only be carried out by trained personnel
who have been instructed by the laser protection officer and are sufficiently qualified to perform the
relevant work.
2.6
Required protection measures
If present in the laser area, protective equipment such as laser protection goggles or special protective
clothing is required. The required protective equipment is stipulated by the laser protection officer
based on the individual hazards caused by the laser equipment. The laser area must be marked so that
the required protective equipment is clearly indicated to all personnel who intend to enter the laser
area.
2.7
Behaviour in case of destroyed zinc selenide (ZnSe) lenses
Only for deflection
units with
ZnSe F-Theta lens
Zinc selenide properties hazardous to health
Destruction of zinc selenide lenses can result in dust containing hydrogen selenide and selenium
dioxide. This dust can be carcinogenic and is very toxic when inhaled.
To improve the optical properties of the material, zinc selenide is frequently given an anti-reflective
coating that may contain thorium fluoride. Thorium is a radioactive element. The quantity of thorium
contained in the coating and the relative size of the decomposed area of the lens surface mean that,
even in the worst cases, the resulting radioactive exposure levels are normally well below the limits set
out in the Radiological Protection Ordinance.
If lenses are damaged:
1. Switch off the laser system immediately.
2. Leave the room for at least 30 minutes.
3. Never remove the lens or the protective window from the deflection unit. Toxic dust or fragments
may have been produced in the deflection unit.
4. If the deflection unit should be opened and fragments fall out, the fragments must only be
collected up using appropriate protective clothing and breathing apparatus and disposed of as
hazardous material in line with the applicable conditions, regulations and legislation.
5. Label the defective deflection unit with a clear warning notice and send the deflection unit to
RAYLASE in air-tight protective packaging.
6. The personnel charged with uninstalling the deflection unit must wear appropriate protective
clothing and breathing apparatus.
7. The room in which the zinc selenide lens was destroyed must be adequately cleaned,
decontaminated and ventilated.
8. Wear gloves and mouth protection when carrying out the subsequent tasks.
9. Carefully collect all fragments and pack them in an air-tight sealable container.
10. Clean all contaminated system components and surfaces with a damp cloth and pack the cleaning
cloths in an air-tight sealable container.
11. Send the containers to the supplier of the optics. They are responsible for proper disposal of the
material.
