Safety
Some lasers have the potential to cause eye damage if aimed directly into the eye, or if someone were to stare directly into a stationary laser beam. Some high-power lasers used in entertainment applications can also cause burns or skin damage if enough energy (typically a stationary beam) is directed onto the human body and at a close enough range. In the United States, the use of lasers in entertainment, like other laser products, is regulated by the Food and Drug Administration (FDA) and additionally by some state regulatory agencies such as New York State which requires licensure of some laser operators. Safety precautions used by laser lighting professionals include beamstops and procedures so that the beam is projected above the heads of the audience. It is possible, and in some countries commonplace, to do deliberate audience scanning. In such a case, the show is supposed to be designed and analyzed to keep the beam moving, so that no harmful amount of laser energy is ever received by any individual audience member.
Lasers used outdoors can pose a risk of "flash blindness" to pilots of aircraft if too-bright light enters the cockpit. In the U.S., outdoor laser use is jointly regulated by the FDA and the Federal Aviation Administration. For details, see the article Lasers and aviation safety.

Famous quotes containing the word safety:
“A lover is never a completely self-reliant person viewing the world through his own eyes, but a hostage to a certain delusion. He becomes a perjurer, all his thoughts and emotions being directed with reference, not to an accurate and just appraisal of the real world but rather to the safety and exaltation of his loved one, and the madness with which he pursues her, transmogrifying his attention, blinds him like a victim.”
—Alexander Theroux (b. 1940)
“There was only one catch and that was Catch-22, which specified that a concern for ones own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didnt, but if he was sane he had to fly them. If he flew them he was crazy and didnt have to; but if he didnt want to he was sane and had to.”
—Joseph Heller (b. 1923)
“There is always safety in valor.”
—Ralph Waldo Emerson (18031882)
