Lasers electrical hazard potential

The two main areas of potential health effects from laser radiation are the eye and the skin. Associated electrical, chemical, and explosive hazards are ako possible. Knowledge of and continued interest in laser safety are necessary in developing applications of lasers. 

Class 4 lasers produce high-power output, above 500 mW. Exposure to the direct beam, specular reflections, or diffuse reflections presents a hazard to both the eyes and skin. A Class 4 laser poses a Are hazard risk (radiant power >2 W/cm is an ignition hazard). These lasers can create hazardous airborne contaminants. They also pose a high-voltage electrical risk. Always enclose the entire laser beam path, if possible, or enclose most of the beam path to reduce the potential hazards.
