Remove all mirror-like surfaces from within the vicinity of the laser beam path to avoid inadvertent reflections. For 3b lasers, eye exams are mandatory. Call Employee Health at 752-2330. Strictly control access to laser area or localized enclosure to necessary personnel. Indoor laser operations should be in a light-tight room with interlocked entrances to ensure that the laser cannot operate while the door is open.
Eye protection is needed for all individuals working in the controlled area.
If laser beam irradiance is sufficient to be a serious skin or fire hazard, suitable shielding or protective clothing must be present between the laser beam and any personnel or combustible material. Beam shutters, beam polarizers, and beam filters should always be used to limit exposure. The flashlamps in optical pump systems should be shielded to eliminate any direct viewing. Backstops should be diffusely reflecting and fire-resistant target materials. Safety enclosures should be used around microwelding and microdrilling work pieces to contain hazardous reflections from the work area.
