hazard considerations for fire (ignition) and byproduct emissions from target or process
materials.
Overview of Laser Safety Classes*
Class Type of lasers Meaning Relationship to
MPE Hazard Area Typical AEL
for CW Lasers
Class 1 Very low
power lasers or
encapsulated
lasers
Safe MPEs are not
exceeded, even for
long exposure
duration (either
100 seconds or
30000 seconds),
even with the use
of optical
instruments No hazard area
(NOHA) 40 µW for blue
Class 1M Very low
power lasers;
either
collimated with
large beam dia-
meter or highly
divergent
Safe for the naked
eye, potentially
hazardous when
optical
instruments** are
used MPEs are not
exceeded for the
naked eye, even for
long exposure
durations, but
maybe exceeded
with the use of
optical
instruments** No hazard area for
the naked eye, but
hazard area for the
use of optical
instruments**
(extended NOHA) Same as Class 1,
distinction with
measurement
requirements
Class 2 Visible low
power lasers
Safe for
unintended
exposure,
prolonged staring
should be avoided Blink reflex limits
exposure duration
to nominally 0.25
seconds. MPE for
0.25 seconds not
exceeded, even
with the use of
optical instruments. No hazard area when
based on unintended
exposure (0.25
seconds exposure
duration) 1 mW
Class 2M Visible low
power lasers;
either
collimated with
large beam
diameter or
highly
divergent
Same as Class 2,
but potentially
hazardous when
optical
instruments** are
used MPE for 0.25
seconds not
exceeded for the
naked eye, but
maybe exceeded
with the use of
optical
instruments** No hazard area for
the naked eye when
based on accidental
exposure (0.25
seconds exposure
duration), but hazard
area for the use of
optical
instruments**
(extended NOHA) Same as Class 2,
distinction with
measurement
requirements
Class 3R Low power
lasers
Safe when handled
carefully. Only MPE with naked
eye and optical 5 times the limit of
Class 1 in UV and 5 times the limit
of Class 1 in UV
