Laser Classes
Class 2M laser components
Class 2M laser components should not cause
permanent damage to the eye under
reasonably foreseeable conditions of operation,
provided that:
l
No optical aids are used (these could focus
the beam).
l
The user’s blink reflex can terminate
exposure (in under 0.25 seconds).
l
Users do not need to look repeatedly at the
beam or reflected light.
l
Exposure is only accidental.
Class 3R laser components
Class 3R laser products emit radiation where
direct intrabeam viewing is potentially
hazardous, but the risk is lower with 3R lasers
than for 3B lasers. Fewer manufacturing
requirements and control measures for 3R laser
users apply than for 3B lasers. Eye protection
and protective clothing are not required. The
laser beam must be terminated at the end of an
appropriate path. Avoid unintentional
reflections. Personnel must be trained in
working with laser equipment.
Class 3B laser components
Class 3B components are unsafe for eye
exposure. Usually only eye protection is
required. Protective gloves may also be used.
Diffuse reflections are safe if viewed for less
than 10 seconds at a minimum distance of 13
cm. There is a risk of fire if the beam encounters
flammable materials. The laser area must be
clearly identified. Use a key switch or other
mechanism to prevent unauthorized use. Use a
clearly visible indicator to show that a laser is in
use, such as “Laser in operation.” Restrict the
laser beam to the working area. Ensure that
there are no reflective surfaces in this area.
