Laser Safety

Radiation Protection Services (RPS) has the responsibility to develop and implement the radiation safety program at Stony Brook University. This guide is provided to aid you in recognizing your responsibility for laser safety and acts as an introductory laser safety trainer.

Engineering Controls

Each laser shall be operated by a master key. An alarm, a warning light or a verbal command is required during start-up activation, and a standard operating procedure shall be followed for the system's operation. The standard operating procedure shall contain the potential hazards, their mitigation or controls and the names of people authorized to operate the laser as well as those responsible for all safety aspects. Appropriate interlock shutters and beam stops must be provided to prevent fires at beam terminations.

Each laser system should be designed to be remotely controlled, enclosed whenever possible and be situated at elevations other than eye level to any personnel whether they are sitting or standing in the laser area. Where target material is purposely interrupting the beam (such as welding applications), the design of the system should include elimination of plume debris by vacuum, by isolation or by the target (especially if toxic material is formed). If beams are reflected by controlled mirror set-ups and the beams must enter free space, the path should be controlled with barriers or the beam should be elevated above head level.
