Class 3B and 4 lasers can present a variety of hazards to both personnel operating the lasers and others through exposure to direct or reflected beams. Additional hazards such as exposure to high voltage power supplies, gas and vapor exposure, noise expo sure and fire hazards must also be considered and factored into laser lab designs and safe operating procedures. This section applies to the acquisition, use, transfer, and disposal of all Class 3B and 4 lasers at NCSU. For medical applications, ANSI Z136.3, Laser Safety in Health Care Facilities, should also be consulted.
Additional sources of non-ionizing radiation exposure exist in our laboratories:
