Class 4 Laser
Safety Instructions
DANGER CLASS 4 LASER
: All visible lasers with beams over 500 milliwatts (1/2 watt) are classified as Class 4.
EXTREME DANGER, MUST BE USED CAREFULLY
DO NOT USE AS A LASER POINTER.
DO NOT USE AS A TOY.
ONLY FOR USE BY PERSONS UNDERSTANDING THE HAZARDS OF THIS LASER.
READ ALL WARNINGS ON THIS PAGE.
DO NOT SHINE DIRECT
BEAM IN EYE-BLINDNESS
HAZARD!
The direct beam at close dis-
tance can cause instant blind-
ness. The direct beam up to
250m/750ft can cause eye
damage. Never aim any laser
towards a person’s head, or
where a person may suddenly
appear. Never aim towards a
pet or other animal.
DO NOT GET REFLECTED
BEAM IN EYE
The beam reflection can cause
instant eye damage, especially
at close range. There are MANY
shiny or smooth objects that can
reflect a laser beam. ALWAYS
be aware of both the main
beam AND its reflection(s). Be
especially careful when aiming
out of windows due to danger
from the “back reflection”.

AVOID EXPOSURE TO BLUE LIGHT
Blue laser light can cause photochemical eye damage. Avoid
prolonged exposure to blue light (light from 530nm green to 380
ultraviolet can be hazardous, with the peak danger at 440nm blue).
There is a hazard even from prolonged exposure to diffused “room
glow” from the beam reflecting off walls or other surfaces. Use safety
glasses that block blue light.
WEAR SAFETY GLASSES
If available, wear laser safety glasses or goggles. They MUST be
appropriate for your laser’s power and wavelength, so the laser
beam’s power is safely reduced. However, DO NOT RELY ON THE
SAFETY GLASSES ALONE. Continue to avoid direct and reflected
exposure to the beam.
