Safety tips

Never look into the beam of any laser.
Wearing a set of proper laser safety goggles is a good idea when working with any laser but especially for those rated Class IIIb or higher.
Be aware of the wavelength(s) and power of your laser(s).
Always terminate the laser beam with a light absorbing material or diffuse screen.
Clearly mark the path of the beam and provide barriers to prevent accidental contact with eyes (all lasers) and other body parts (high power lasers).
Follow all relevant electrical safety precautions.
Provide a 'kill' switch in an accessible location away from the laser.
Put appropriate laser safety and electrical safety warning/danger stickers near the laser emission aperture and other beam path locations, on the laser, and on power supply components.
Instruct anyone else with you as to the hazards of laser light and make sure they understand all of these guidelines. Those with you may actually be in MORE danger because they will be looking toward the direction of the action while you will know what to expect and avoid.
