All lasers and laser light show systems have intrinsic dangers - even laser pointers! Observation of basic laser safety rules and the specific safety regulations of the jurisdiction in which you operate are essential.

A laser can be considered as a highly collimated source of extremely intense electromagnetic radiation that is defined by three characteristics: monochromatic, directional and coherent. Due to the temporal and spatial coherence of the laser beam it can be considered as a point source of phenomenal brightness than can easily exceed the brightness of the sun. Lasers are a more directional light source than any other common fixture such as stage lights or a follow-spot. The higher the optical output power of the laser, the greater the potential hazard.

Audience Scanning
In enlightened jurisdictions where audience scanning is permitted, as the laser operator you must take all precautions to make sure the audience scanning effects are intrinsically safe. The power of the effects used must meet the exposure levels permitted in your area. Audience scanning is a big responsibility as you could ruin hundreds of people's vision.
