Which of the following are primary components of a fire protection system?

The primary components of a fire protection system are essential for detecting, controlling, and extinguishing fires effectively. The group that includes fire alarms, smoke detectors, and fire extinguishers represents the core of a fire protection strategy.

Fire alarms are critical for notifying occupants of a fire situation, facilitating timely evacuation and response from emergency services. Smoke detectors play a vital role in early fire detection, alerting occupants to the presence of smoke and potential fire even before it becomes visible. Fire extinguishers are crucial for the immediate control of a small fire, allowing trained individuals to take action before fire spreads, thereby minimizing property damage and enhancing safety.

Understanding these components highlights the proactive measures that can be taken in ensuring safety from fire hazards. The other options feature important safety measures, but they do not represent the core components of a fire protection system in the same direct manner as the correct answer does.
