Laser Safety

UNC Charlotte EHS has developed a Laser Safety Manual and supporting programs to help ensure the safety of laser users. 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 exposure 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 UNC Charlotte. For medical applications, ANSI Z136.3, Laser Safety in Health Care Facilities, should also be consulted.

What you need to know

  • All class 3B and 4 Lasers must be registered with EHS using the Laser Registration Form Below.
  • Laser inventories are managed using the EHSA Onsite database.
  • PI’s must ensure the proper PPE is available for working with the lasers in their lab and that users are trained on their specific equipment.
  • Laser cutters/engravers may present additional hazards and should also be assessed.
