Many scientists involved with lasers agree on the following guidelines:      Everyone who uses a laser should be aware of the risks. This awareness is not just a matter of time spent with lasers; to the contrary, long-term dealing with invisible risks such as from infrared laser beams tends to reduce risk awareness, rather than to sharpen it, primarily due to complacency. Optical experiments should be carried out on an optical table with all laser beams travelling in the horizontal plane only, and all beams should be stopped at the edges of the table. Users should never put their eyes at the level of the horizontal plane where the beams are, in case of reflected beams that leave the table. Watches, and other jewelry that might enter the optical plane, should not be allowed in the laboratory.

Nonetheless, in health care facilities, lasers, of varying types and wavelengths measured in nm , are used for incisions and excisions in surgery, sealing blood vessels in the retina, removing wrinkles or conducting other plastic surgery processing, treating malignant tissues, and an assortment of other treatments. These processes are valued for their enhanced efficiencies, but they are by no means devoid of hazards.
The word laser is actually an acronym. In the medical industry and in the application of health care, these coherent light sources can make cuts that do not bleed and can assist in the diagnosis of disease, but they damage the eyes and skin and present non-beam hazards.
It provides specific processes to protect anyone who might become exposed to laser radiation and assists in establishing a program to promote the safe use of health care laser systems HCLSs. ANSI Z This includes hospital facilities, ambulatory surgery centers ASC , and individual medical, dental, and veterinarian offices, as well as non-medical locations, such as salons and spas. HCLSs include a delivery system to direct the output of the laser, a power supply with laser control and calibrations, protecting housing, and associated liquids and gases.
The standard also provides guidance to employers for establishing laser safety policies and procedures and training programs in safe laser use, and it includes engineering, procedural, and administrative controls and laser safety training.
The document also details information on the environment, non-beam hazards, and examinations following laser-induced injuries. Overall, the standard is intended for use by all people associated with the application, installation, operation, calibration, maintenance, and service of an HCLS, as well as others exposed to lasers being used as medical devices or in health care applications.
You can get both of these standards together as:.
