What should you do after a suspected laser eye or skin exposure?

Short answer
Stop the machine, send the person to the school nurse or campus health service now, and report it the same day to whoever is responsible for the equipment, even if the person feels fine. The machine stays out of service until that person has reviewed what happened and released it.
Stop, get medical evaluation, report, tag out, and wait for release, in that order. Conceptual: who the responsible person is depends on your district or campus policy and written emergency plan, and this covers enclosed Class 1 or 2 machines in their actual configuration.
This answer assumes an enclosed machine at Class 1 or 2 in its actual configuration. On that kind of machine, a reported flash, afterimage, eye pain, burn or any other symptom means something happened that should not have, so a safeguard is in doubt until someone qualified says otherwise. If your machine is open-frame, open-bed, pass-through, converted, Class 3B or 4 in normal use, or of unknown class, this page does not cover it. You need a laser safety officer and a written program first.
Do not wait to see whether symptoms develop, and do not let the person decide whether it was serious. Symptoms are not a reliable measure of severity. One national laboratory’s bio-effects page notes that an exposure to an invisible beam may go unnoticed at first because the retina lacks pain nerves. Its example is a different kind of laser than a classroom cutter, but the general point holds, which is why a clinician checks the eye rather than the person who was exposed. University procedures also tell anyone who suspects an exposure to seek immediate medical attention. For severe injuries, such as loss of vision, bleeding from the eye or serious burns, call 911.
Take the machine out of service: power it down, secure it, label it OUT OF SERVICE, and do not reopen a lid or door to test what happened. Only authorized service works on it. One university’s accident procedure says not to resume use of the laser until the laser safety authority has reviewed the incident. In a school, who that is depends on your district or campus policy, and your written emergency plan decides the rest.
