Certified Home Health Aide (CHHA) Practice Exam

Smoke detectors are NOT which of the following?

Devices for earthquakes Devices for detecting smoke Assist with detecting fires Alert when there are smoke and fires

Correct Answer:

Devices for earthquakes

Explanation:

Smoke detectors are designed to sense smoke in the air and alert people to a potential fire, providing early warning so occupants can evacuate and responders can act quickly. They are not devices for earthquakes, which are detected by different systems such as seismic sensors. So the statement that smoke detectors are devices for earthquakes is not true. The other descriptions fit: they are devices for detecting smoke, they assist with detecting fires, and they alert when there is smoke (which can indicate fire). In everyday use, keep detectors installed in key areas, test them monthly, and replace batteries or units as recommended to ensure they function when needed.
