Lasers and laser systems are classified based on their potential to cause injury, indicated by the laser output energy or power and wavelengths. Designated classifications are included on the instrument's laser hazard label and in the manufacturer's operating instructions.

EH&S must review and classify lasers without classification labels and lasers constructed or modified in labs. Get prior approval from EH&S if you plan to use Class 3B or Class 4 lasers.

We review laser/non-ionizing radiation permit applications according to radiation authorizations procedures.
