2.3 SAFETY ENCLOSURE (AT YOUR WORK STATION)
1) Potential hazards
CO
2
beam is delivery from oscillator. Direct or scattered beam is
exposed.
2) Safety recommendations
Mount the safety enclosure made of acrylic resin which can
absorb the laser beam around the working environment.
Mount the interlock switch on the safety enclosure door which
extinguishes the laser beam output when the door is open. Never
perform operation without safety cover of laser machine.
2.4 FIRE
1) Potential hazards
When you work with the laser oscillator or machine, hot
fragments or slag can scatter from your workpiece. The CO
2
beam or a reflection of it could ignite flammable material.
2) Safety recommendations
The direct or scattered laser beam can ignite flammable materials
such as paper, cloth, and wood. Provide a beam absorber behind
the workpiece and around it during maintenance. The absorber
can be anodized aluminum, graphite or brick.Put a shield
between yourself and the workpiece when the CO
2
beam is on.
Even diffuse reflections can harm eyes and skin and may ignite
flammable material.
2.5 TOXIC FUME
1) Potential hazards
Some materials such as certain plastics can emit toxic fume when
they burn under the laser beam.
2) Safety recommendations
Install the exhaust system to remove toxic fume from the work
environment.
Consult the manufacturer of the material you are processing to
learn if it creates any fumes when heated or burned.
