Laser Shows in Raves and Discos - Safety With Lasers

Audience scanning is when a laser beam is projected at the audience instead of over their heads. The laser beams actually attain out and touch the audience, covering them in rippling sheets, waves and tunnels of emerald and colored laser light. Audience scanning is the most crowd pleasing laser impact for any type of laser show and one that completely immerses the audience in the laser experience.

Audience scanning although is not with out its dangers and strict controls are required to ensure the security of the audience. Audience scanning is regarded as to be too risky in the US and topic to constantly changing regulations, is banned in most if not all states. Unlike the US, Audience scanning is allowed in Europe subject to controls outlined by the International Laser Display Association (ILDA) after 1998.

The main control for audience scanning is Maximum Permissible Exposure (MPE). MPE is the maximum exposure a member of an audience been scanned can have to a laser light that is regarded as safe. If a venue does not exceed the MPE, audience scanning is safe and permissible. MPE is standard in all countries but the techniques used to calculate the amount of light an eye is subject to varies and is calculated more conservatively in some nations than others.

Regardless of the issues some people have, audience scanning in a venue that uses MPE to control the laser show is very safe. MPE's have been calculated to include a safety aspect and are set ten times below the level of exposure that would cause an injury in 50% of people's eyes. This means that individuals would require 10 occasions more exposure to laser beams before they had a 50% injury to their eyes.

Following the recent debacle in Russia where a number of individuals at a rave where blinded by audience scanning, many clubbers are afraid of audience scanning. The Russian rave tragedy occurred because the organizers and people operating the lasers had no concept what they had been performing, had been not educated and were not professional. One of the golden rules for audience scanning outlined by ILDA is pulsed lasers that provide short high energy pulses of light are Never allowed. These cretins at the Russian rave used pulsed lasers.
