Laser Safety
The Department of Chemistry and Chemical Biology uses Class 3B and Class 4 lasers in selected research laboratories. These lasers present significant eye, skin, electrical, and fire hazards if not used properly. Work with Class 3B and Class 4 lasers is restricted to authorized personnel who have completed the required training and follow approved laboratory procedures. Department laser laboratories are inspected annually by Environmental Health & Safety (EHS) and are routinely monitored by laboratory personnel to help maintain a safe research environment.
Important: Never enter a laser laboratory displaying an active laser warning unless you are authorized, have received the required training, and are wearing the appropriate laser safety eyewear.
Before Working with a Laser
Before operating a Class 3B or Class 4 laser, you must:
- Complete required laser safety training.
- Receive laboratory-specific training from your Principal Investigator (PI) or supervisor.
- Review applicable Standard Operating Procedures (SOPs).
- Wear laser safety eyewear appropriate for the laser wavelength and optical density.
- Understand laboratory access controls, warning signs, and emergency procedures.
Laser Safety Responsibilities
Laser users are expected to:
- Follow approved operating procedures.
- Wear the required PPE at all times.
- Never bypass safety interlocks or engineering controls.
- Keep beam paths enclosed whenever practical.
- Remove unnecessary reflective objects from the work area.
- Maintain appropriate warning signs and restricted access during laser operation.
- Report damaged equipment, unsafe conditions, or incidents immediately.
If a Laser Incident Occurs
If a laser-related injury, exposure, or equipment malfunction occurs:
- Stop work immediately if it is safe to do so.
- Secure the area and prevent additional exposure.
- Notify your supervisor or Principal Investigator.
- Seek medical attention immediately for any suspected eye or skin exposure.
- Report the incident using the Department's Incident Reporting process.
