Lasers are categorized into classes based on their potential hazards. Dangerous laser classes are 3B and 4, which require additional safety measures depending on local laser safety regulations. The manufacturer is responsible for ensuring the correct classification of laser lights, and this classification applies specifically to the laser system, not the potential hazardousness of audience scanning. In audience areas, the Maximum Permissible Exposure (MPE) must not be exceeded, even with high-powered laser beam lights such as Class 4 lasers in the visible spectrum. All laser lights offered by Laserworld emit in the visible spectrum and operate as continuous-wave lasers, meaning they are safe when appropriate measures are in place.
