The following are design requirements for carbon dioxide and nitrogen gas lasers:
- (1) A sufficient thickness of firebrick, asbestos, or other fire retardant material shall be provided as a backstop for the beam to provide fire protection.
- (2) The use of this type of laser shall be such as to preclude the exposure of individuals to hazardous levels of ionizing and/or ultra-violet radiation.
- (3) Reflections of the infrared laser beam shall be attenuated by enclosure of the beam and target area or by the use of eyewear constructed of a material opaque to the carbon dioxide wavelength, such as plexiglass.
