Final answer:
The statement is false; smoke alarms are essential in both the workplace and residential settings for early fire detection and evacuation safety.
Step-by-step explanation:
The statement "Smoke alarms are only necessary in the workplace" is false. Smoke alarms are critical safety devices that are necessary not only in the workplace but also in homes, schools, and any buildings where people spend time. The primary purpose of a smoke alarm is to provide early warning in the event of a fire, allowing individuals to safely evacuate the premises. It is a key component in residential and commercial fire safety protocols. Smoke alarms are especially vital in residential settings during nighttime hours when occupants are likely sleeping and less aware of their surroundings.
