4) Always wear laser goggles appropriate for the wavelength
generated and the beam intensity.
5) The laser equipment area must be brightly lit so the pupils of the
operator’s eyes are normally constricted.
6) A fire-resistant background should be placed behind target
areas.
7) Surrounding work areas should be coated with a material that
absorbs scattered radiation.
8) Operators should not wear or use any object that may reflect
laser light such as a watch, ring, pen, etc.
9) Tracking individuals, vehicular traffic, aircraft, or any airborne
object using laser radiation is prohibited.
Optical safety
1) Be sure that the light from the flashlamps is obscured from the
eye as it is damaging if viewed directly.
2) Eye safety is the greatest concern. Be aware at all times that this
is a Class IV laser, the highest and most dangerous classification.
Specular reflections from the main beam off a polished surface
can cause severe eye damage.
3) Be sure that there are no volatile substances in the lab which the
laser could ignite.
4) Mark the lab well with warning signs when the laser is operat-
ing and provide interlocks for all doors.
Electrical safety
1) To prevent accidents due to electrical shock, care should be
taken to be sure the capacitors are completely discharged and
the power turned off before any maintenance or repairs are
made to the system. Electric shock and burns resulting from
input power or capacitor discharge can cause serious injury or
death.
2) Be aware that high voltages are present in the laser heads once
ac power is toggled on.
3) This laser equipment must be turned off when not in use.
