Laser Safety Manual

30 Laser Safety Manual • Be very cautious around lasers that operate at wavelengths not visible to the human eye. • Do not wear bright, reflective jewelry, or other reflective objects. Outdoor Laser Use Safety Practices • Terminate the beam at the end of its useful path whenever possible. • Locate the beam path at a point other than eye level. • Prohibit beam propagation across pedestrian or vehicular thoroughfares. • Select a height that avoids the eyes of area workers. • Minimize specular reflections and use non-reflective tools. • Enclose beams as much as possible. • Locate lasers so that no beam hazard exists at locations where personnel are normally present. • Post CAUTION signs in operational areas. • Avoid direct beam viewing to align lasers. • Design outdoor laser areas so that personnel can enter and leave the controlled area under emergency conditions. • Design doors, gates, or other access control devices to laser areas so that they do not impede emergency egress. • Post a laser classification label at each entrance to a controlled outdoor laser area. • Install visual or audible beam-warnings for invisible lasers. • Activate all warning devices whenever the beam is on. • Check the requirements for flight zones contained in FAA Order 7400.2E, Procedures for handling Airspace Matters, reference ANSI Z136.6, Appendix A.
