Where do people commonly place smoke detectors according to safety standards?

Smoke detectors are commonly recommended to be placed on every floor of a building according to safety standards. This practice ensures comprehensive coverage throughout a home or facility, allowing for early detection of smoke or fire in different areas. Placing detectors on each level increases the likelihood of alarming occupants in the event of a fire, regardless of where it may start.

While some options suggest placing detectors only in certain areas like kitchens or bedrooms, these approaches would leave large portions of a home unmonitored and could potentially delay warning occupants, increasing risks. By ensuring that detectors are installed on every floor, including common areas and bedrooms, safety standards aim to maximize safety and provide ample time for evacuation should a fire occur.
