This includes virtually all University buildings. Warning Devices T here should be a red warning light and warning sign outside of any laser room or light barrier enclosure. Personal Protective Equipment L asers present a serious threat of damage to eyes. Eye protection must be appropriate to the particular laser in use. Wavelengths and operational power levels must be taken into consideration when selecting protective glasses or goggles.
Some lasers present a potential for skin damage.
Lab coats or long sleeved garments should be used at all times when working in a laser environment. Laser Work Area E ngineering controls are the fundamental tenets of a sound laser safety program. Control measures shall be devised to reduce the possibility of exposure of the eyes and skin to hazardous laser radiation. Engineering controls, which are incorporated into the laser or laser system itself, or added to the installation by the user, are almost always the preferred method for controlling access to laser radiation. The interlocked physical barrier is required for all lasers of 100W or more.
