Sources of electrical hazard from lasers come primarily from the power supply of CW lasers and the capacitor banks of pulsed lasers. Avoid wearing metallic items. Never handle electrical equipment when hands are wet or when standing on wet ground. Personnel should be trained in CPR in case an electrical accident occurs. Chemical Hazards Sources of chemical hazards One of the major sources of chemical hazards from lasers is from the organic dyes used in dye lasers.
Most dyes used in dye lasers are fluorescent organic compounds.
Other hazards include gases from gas lasers, as well as gases that are formed by the interaction of the laser with target materials, and coolants such as liquid nitrogen. Sources of non-beam optical hazards There are hazards from light generated by lasers which do not originate from the beam itself. Control Measures Engineering Adminstrative PPE Engineering Controls Engineering controls are design features or devices that are applied to a laser or its environment for the purpose of reducing laser hazards. Engineering controls are considered to be the most effective types of control. Examples of engineering controls are beam housings, beam shutters, attenuators, and remote firing controls.
