Hazard control measures can be categorized as either administrative procedures, personnel protective equipment (eye protectors, respirators, gloves, etc.), or engineering controls for the laser and environment. Engineering controls, although typically more costly, are generally considered more reliable, since one does not have to depend upon individuals to follow certain rigorous procedures to avoid hazardous exposures. Individuals could forget to don protective eyewear, drape windows, or cover reflective surfaces. Examples of engineering controls are the installation of baffles, laser protective filters installed in doors, shutters on windows, low-reflectance walls, and laser system safety features (such as protective housings for the laser, key-locked switches, and interlocks).
