Safety

2.2 Laser safety

2.2.1 Laser classification

The laser safety class indicates the risk potential from accessible laser radiation.

The laser system is a Class 2 (US: Class II) laser marking system as per IEC 60825-1 "Safety of Laser
Products".

Warning Laser

Laser radiation of Class 2 (US: class II)

For Class 2 (US: class II) laser is short term exposure (up to 0.25 seconds) harmless to
the eyes and can therefore be operated without additional protective measures. However it
can cause irritation of the eyes if the natural avoidance reaction (staring into the laser beam
deliberately) or eyelid closure reflex is suppressed.

– Do not suppress the eyelid closure reflex.
– Do not stare directly into the laser beam.
– Close eyes, turn away.
– Never look at the laser beam directly with an optical instrument, e.g. a lens.

Class 2 (US: class II)

The accessible laser radiation of Class 2 (US: Class II) laser systems does not pose any hazard for the skin.
Diffuse reflections as well as any short-term irradiation of the eyes (exposure time max. 0.25 seconds) also
pose no risk due to the low output power.

However, it is possible to suppress the natural eyelid closure reflex and stare into the class-2 laser beam for
a time long enough for the eyes to get injured.

Furthermore, gases formed beneath the material being processed may ignite, especially if the extraction
requirements are not met.

The risk of flaming is increased in case of insufficient care and cleaning as well.

Additionally, regularly control the air cooling system on your laser. In particular, the filters and ventilators
should be checked regularly for proper function to avoid defects caused by overheating.

Safety

2.8.2 Gases, fumes and dust

Depending on the materials being processed and the parameters selected, laser processing may generate
gases, fumes, aerosols or dust. Depending on the material, such by-products may be toxic. In individual
cases, the reaction products may be electrically conductive dusts. If these enter electric systems, short­circuiting with personal injury and property damage may occur.

The operator is responsible for ensuring presence of a suitable extraction system and compliance with the
relevant guidelines in order to protect persons and the environment. The guideline VDI 2262 1-3 "Workplace
air" provides, among other things, additional remarks.

The operator must also ensure that gases, fumes or dust do not settle on the processing lens. Any dirt
accumulating on the processing lens can lead to loss of performance, poor processing results and damage
to the device.

2.8.3 Reflection through materials

Warning

Danger from laser beam.

Invisible laser radiation of reflecting materials can cause serious injury or material damage.

– Only material according to the intended use of the machine may be used.
– Do not use material with high reflecting surfaces such as aluminum, chromium, precious

metals, metal foils, stainless steel, brass, copper and titanium.
– Take special care with surfaces formed convex and concave.
– Do not leave or put objects on the work surface/working area.

Laser beam reflection

The reflecting law is valid for the reflection of the laser radiation: Angle of incidence = failure corner

No. Description

1 Directed reflection: Reflected ray on smooth surface.

2 Directed reflection: Reflected ray on sloping surface.

3 Diffuse reflection: Reflected ray on rough surface.

4 Directed reflection: Horizontally reflected ray on smooth surface.

2.8.4 Information about damaged optics

Warning

Damage to optics.

Soiled optics absorb laser radiation and can thus be destroyed. Broken or damaged lenses as
well as thermal decomposition of lenses release particles which cause serious damage to the
health.

– The passive reflectors and optics in the area of the laser beam guidance should be cleaned

regularly.
– Special care is required when handling, attaching and cleaning these elements.
– Do not exert non-uniform pressure.
– Do not use tools or hard objects to clean the surface.
– Never touch the optics with your bare fingers.
– Never use cleaning tissues twice.
– When lenses get broken, damaged or thermal decomposed follow the protective measures.
– Disposal according to regulations and laws valid in the user's country.
– Lenses with scratches or lenses with penetrations must not be used anymore!

Scratched or destroyed lens surface

Be aware that scratches in the coating may release small quantities of thorium, which may be harmful upon
inhalation or swallowing.

Thermal decomposition

Upon thermal decompositions, vapors of selenium oxide and zinc oxide are formed. Upon inhalation or
swallowing there is danger of poisoning. Indicators for thermal decomposition of ZnSe include deposits in the
form of red or white powder and an unpleasant odor.

Broken lenses

When optical components of zinc selenide (ZnSe) are destroyed, toxic dusts and vapors are formed which
must not be inhaled. The dust can additionally cause irritations of the eyes, skin and respiratory tract. If a
lens has been destroyed during operations, care is to be taken during removal and cleaning.

2.8.5 Protective measures for damaged optics

Protective measures in case of thermal decomposition and scratched or broken lenses

•

For disposal use a protective mask or respiratory filter to prevent inhalation or ingestion of thorium.

•

Wash hands thoroughly after contact with a scratched coating.

Protective measures in case of a broken lens

•

Upon perception of an unpleasant odor, switch off the machine.

•

Hold your breath.

•

Leave the area of the machine.

•

Before approaching the system again, wait for at least 30 min until the reaction has abated.

•

Wear proper protective clothing (respiratory protection, protective goggles, protective suit, rubber or
plastic gloves).

•

Provide ventilation.

•

When approaching the system again, pay attention to odors.

•

Remove all lens fragments.

•

Avoid raising or dispersing dust.

Safety

Disposal

The ZnSe dust and the lens are to be collected drily and disposed of with fragments, broom,
shovel and protective clothing into hermetically sealable containers or plastics bags as
hazardous waste.

Do not dispose of optical components as domestic waste, and do not let them enter the
sewer or water bodies.

Dispose of according to regulations and laws valid in the users' country.

Safety

2.9 In case of emergency

In case of malfunction

•

In case of unusual operating states, open the acrylic top lid to stop working process or respectively press
the Emergency stop button, if available and switch off the laser device.

•

When appropriate disconnect the machine from the mains.

•

Inform laser safety officer and supervisor.

•

Follow the Operating manual.

•

Have repair work performed by Trotec Laser GmbH service technicians only.

•

In case of fire: Use only CO2 fire extinguisher to quench the fire, insofar as this is possible without
endangering yourself.

Notice

After a deletion, Trotec Technical Support must be involved before the system is put back into
operation.

In case of accident, First Aid

•

If due to laser irradiation eye injury has occurred (upon exceedance of the maximum allowable irradiation
rate), the accident victim must immediately be presented to an ophthalmologist.

•

Assumption of eye injury is justified whenever laser irradiation has occurred and the maximum allowable
irradiation rate may have been exceeded.

•

First aider must pay attention to self-protection.

•

Power off the device.

•

Remove injured person from the danger zone and provide First Aid.

•

Call emergency doctor!
