LIMITATIONS

OF SMOKE

DETECTORS

Smoke detectors

offer the earliest warning

of fire possible

at a reasonable

cost. They have saved thousands

of lives in the past

and will save more in the future. Nevertheless,

smoke detectors have limitations.

They may not provide early warning

of a fire developing

on another

level of a building. A first-floor detector,

for example,

may not

detect a second floor fire. For this reason, detectors

should be located on every level of a building.

In addition, detectors

may not

sense a fire developing

on the other side of a closed door. In areas where doors are usually closed, detectors

should be installed

on both sides of the door.

Detectors

have sensing limitations,

too. Ionization

detectors

offer a broad range of fire-sensing

capability,

but they are better at

detecting

fast, flaming fires than slow, smoldering

fires, Photoelectronic

detectors

sense smoldering

flames better than flaming

fires. Because

fires develop in different ways, and are often unpredictable

in their growth, neither type of detector is always best,

and a given detector

may not always provide warnings

of a fire. In general, detectors

cannot be expected

to provide warnings

for

fires resulting

from inadequate

fire protection

practices,

violent explosions,

escaping

gas, improper

storage of flammable

liquids

like cleaning

solvents, other safety hazards, or arson.
