Lasers

UW Office of Radiation Safety (ORS) works with users of high powered lasers to ensure that they are used safely. The Laser Safety comprises of the Medical and Research Laser Safety program for UW–Madison and UW–Health.

Laser Registration

All Class 3B and Class 4 research lasers should be registered with the ORS upon receiving them.

Medical Clearance

Occupational Medicine provides laser operator eye exams and medical clearance required for UW–Madison faculty, staff and student to receive approval for 3B or 4 laser access from ORS.

Login to MyUHS for laser operator medical clearance:

  • Submit one-time ‘Forms’: “Privacy Notice and Consent to Treat” and “Authorization for Release of Occupational Health Records” if incomplete
  • Complete the ‘OM Laser Operator Questionnaire’
  • See patient info for more detailed instructions

Training Process

On the Job Training

The PI/Supervisor or designee is responsible for giving the laser specific operating training covering the alignment procedures, administrative procedures, and other applicable SOPs. The record of the training shall be documented.

Online Required Training

A number of laser safety trainings are available online. Review the options here.

Warning signs, labels, and illuminated warning lights

The warning signs and lights warn the presence of a laser hazard inside the lab. Once you register the laser, ORS will do your lab assessment and help you with the signage.

Emergencies

Call 911 in all emergencies.

For reporting exposures not resulting in a severe injury

  • Stop all work and shut down all lasers in the lab
  • Notify your supervisor and ORS immediately
  • Fill out the injury reporting forms and submit through your department’s human resources representative.

Cleaning and disinfecting laser eyewear during COVID-19

Laser eye protection should not be shared if feasible. If reissued safety eyewear to another user, they should be disinfected using the manufacturer’s recommendations on proper cleaning and care.

Some manufacturers suggest mild soap and warm water (not hot) water. Be sure that the soap is free of any abrasives (such as microbeads or grit). With clean hands, rinse the eyewear, and apply a small amount of soap with your fingertips. Do not use circular motions whilst cleaning as this may affect coatings. Dry with soft lint-free cloth by pressing gently against water droplets. Avoid rubbing as much as possible. This cloth should be kept somewhere where it will stay clean and should be washed weekly if possible, without fabric softener or dryer sheets. Any dust or dirt that accumulates in the cloth can damage the eyewear. Special care is needed for laser eyewear with coatings and most manufacturers provide special instructions for these.

Inspect eyewear regularly, especially after cleaning.
Be aware that laser system manufacturers often distribute eyewear as a third party. Be sure to follow the original manufacturer’s instructions.
