What is a smoke detector?

• A. A device for detecting temperature changes
• B. A listed device that senses combustion particles
• C. A device that alerts the fire department
• D. A non-listed fire safety device

Answer: (B)

A smoke detector is specifically designed to identify the presence of combustion particles in the air. This is achieved through various sensing mechanisms that can detect smoke, which is often a result of fire or combustion processes. Smoke detectors play a crucial role in fire safety by providing early warning to occupants and enabling them to take appropriate action, such as evacuating the premises or notifying emergency services. The significance of properly functioning smoke detectors is highlighted by their ability to detect smoke even before flames are present, offering critical early notification. This timely alert can be the difference between a minor incident and a major disaster. While other devices might monitor temperature changes or alert the fire department, a smoke detector's primary function is its ability to sense specific particles associated with combustion—making option B the most accurate description of a smoke detector's purpose.
