With respect to the requirements of remote interlock connector, key control,
beam attenuator, and emission indicator, Class 3B laser products not exceeding
five times the AEL of Class 2 in the wavelength range of 400 to 700 nm are to be
treated as Class 3A laser products.

Remote
interlock
Not required
Connect the remote interlock
of the laser beam to the
emergency main interlock,
the interlock of the room, or
the interlock of the door.
Key control
Not required
Do not keep the key in the
lock when the laser beam is
not used.
Beam breaker
or attenuator Not required
Used to protect people from
accidental radiation by the
laser beam.
Warning sign
Not required
Post a proper warning sign on the door to the
room where laser beam equipment is installed.
Beam path
Not required
The laser beam must be terminated and, as a rule, must be enclosed. If the
laser beam is exposed, the vertical height of the beam must not be the
same as that of the eyes.
Mirror
reflection Not required
Appropriate optical elements must be securely
attached and you must be able to control the opti-
cal elements during laser radiation.
Eye protec-
tion
Not required
Use eye protectors except in
special, specified locations.
Protection
clothes
Not required
Wear protection clothes if exposure of the skin to the laser
beam may exceed the MPE of the skin.
Training
Not required
The laser system must be operated by only properly trained
people.
