  • Class 3B and 4 lasers are regulated by the State of Florida and must be registered with the UF EH&S Laser Safety Program.

    Additionally, there are several requirements based on the class of the laser which are listed below.  However, each laser is evaluated and more or less requirements may apply based on circumstance. Class 1, 2 and 3R lasers are not regulated and therefore no laser safety precautions are necessary.

    Contact the UF Laser Safety Officer with any questions.

    Online Training

    Anyone that works in a lab with an active Class 3B or 4 laser is required to take the online training UF_EHS833_OLT. Users of re-classified microscopes are required to take this training as well. Please visit MyTraining to complete the course.
