Tempest Nd:YAG Laser Operator’s Manual
4
At all times during installation, operation, maintenance or service of
your laser, avoid exposure to laser or collateral radiation exceeding
the accessible emission limits listed in “Performance Standards for
Laser Products,” 21 CFR 1040 10(d).
Laser light poses safety hazards that are not associated with conventional
light sources. Special precautions must be observed when working with
the Tempest pulsed Nd:YAG laser. The safe use of lasers requires that
all laser users, and people working in the same area as the laser, are
aware of the dangers involved.
Laser beams are intense enough to burn skin, clothing or paint. They can
ignite volatile substances such as alcohol, or other solvents. The beam
may also cause damage if reflected from some other surface. For this
reason it is important that the following precautions are observed.
• Keep the protective cover on the laser head at all times.
• Avoid looking at the output beam, even diffuse reflections are
hazardous.
• Treat back reflections from any optic surface as you would the main
laser beam. Even though the energy of such reflections is only a
fraction of that contained in the main beam, it is sufficient to cause
serious bodily harm, especially to the eye.
• Use protective eyewear at all times. Selection depends on the
wavelength and the intensity of the radiation, the conditions of use,
and the visual function required.
• Operate the laser at the lowest beam intensity possible, given the
requirements of the application.
• Expand the beam wherever possible to reduce beam intensity.
• Avoid blocking the output beam or its reflection with any part of the
body.
• Use an IR detector or energy detector to verify that the laser beam is
off before working in front of the laser.
• Establish a controlled access area for laser operation. Limit access to
those trained in the principles of laser safety.
