What safety device signals an alarm when smoke is present?

What safety device signals an alarm when smoke is present?

• A. Smoke Detectors
• B. Three Points of Contact
• C. Safe Approach Distance
• D. Point of Operation

Answer: (A)

Detecting smoke and sounding an alarm is the job of a smoke detector. It senses smoke particles in the air and triggers an audible or visual alarm to alert people and initiate fire-response actions. The other terms refer to safety practices or machine guarding rather than smoke detection: three points of contact is about maintaining balance to prevent falls, safe approach distance is about staying away from hazards, and the point of operation is the part of a machine where work is performed and guarded. So, the device that signals an alarm when smoke is present is the smoke detector.
