2-2 Laser Safety and Compliance
Safety Precautions for Class IV High Power Lasers
Use an infrared detector or energy detector (IR viewer) to verify that the laser beam
is off before working in front of the laser.
Operate the laser at the lowest beam intensity possible, given the requirements of
the application.
Expand the beam whenever possible to reduce beam power density.
Avoid blocking the output beam or its reflection with any part of your body.
Establish a controlled access area for laser operation. Limit access to those trained
in the principles of laser safety.
Post prominent warning signs near the laser operating area (Figure 2-1).
Set up the laser so that the beam is either above or below eye level.
Provide enclosures for beam paths whenever possible.
Set up shields to prevent specular reflections.
Set up an energy absorbing target to capture the laser beam, preventing unnecessary
reflections or scattering (
Figure 2-2).

Follow the instructions contained in this manual for safe operation of your laser. At all
times during operation, maintenance, or service of your laser, avoid unnecessary
exposure to laser or collateral radiation

that exceeds the accessible emission limits
listed in “Performance Standards for Laser Products,” United States Code of Federal
Regulations, 21CFR1040 10(d).
The use of controls or adjustments, or the performance
of procedures other than those specified herein, may
result in hazardous radiation exposure.
1. Any electronic product radiation, except laser radiation, emitted by a laser product as a result of, or
necessary for, the operation of a laser incorporated into that product.
