ABSTRACT
Traditional laser safety training talks about laser accidents, common causes, who they happen to, but rarely talks about the real logistics of the event. Authorized laser users will be familiar with the Building Emergency Plan, location of emergency equipment, and emergency procedures for fires, earthquakes, and evacuations. Emergency shut-off for lasers is done at the electrical panel circuit breakers or by electrical shut off switches. Accidental laser beam exposure is a serious event. In the case of suspected laser injury, operations will be ceased and the laser set-up will remain unchanged to allow for analysis of the cause of the accident. Ultra violet wavelengths can cause cornea and lens injury. The nature of ultra violet cornea injury is that there is no immediate sensation of injury, so the pain response does not manifest itself for on average 10 hours. So, many times, the person is away from the work environment when they feel pain.
