What do system interlocks accomplish in laser safety?

• A. The laser cannot operate when the housing is opened or removed.
• B. They prevent the beam from exiting the system entirely.
• C. They ensure beam height is maintained.
• D. They control warning lights.

Answer: (B)

System interlocks are safety features tied to the protective housing that ensure laser emission cannot occur while the housing is open. Their job is to immediately disable the laser if a door or panel is opened or removed, preventing exposure to the beam. This is why the interlocks are described as preventing operation when the housing is breached. They do not primarily keep the beam from exiting the system after emission, nor do they set beam height or control warning lights—those are separate aspects of a laser safety system, though warning indicators may be part of the interlock circuit.
