Fire Detection & Smoke Detection

Fire Detection
The earlier a fire can be detected, the more time there is for occupants to escape and the better are the chances of extinguishing or at least containing the fire. A wide range of devices exists for detecting either heat or smoke.

Smoke Detection
Smoke is usually the first detectable sign of any carbonaceous fire, therefore, smoke detectors are most frequently used unless there are problems with steam or dust, etc., which may trigger false alarms.

Ionising detectors operate when smoke enters the detector and it absorbs ions, reducing the flow of electrical current. These devices are very sensitive to smoke and may be triggered by cigarette smoke and dust, etc.

Light scatter detectors operate when smoke scatters a beam of light.

Obscuration detectors operate when smoke enters the detector preventing light from reaching a photoelectric cell.

Fire Fighting Equipments

Sprinklers
Sprinklers may start automatically when the fire alarm is activated, or when a predefined temperature has been reached. Some sprinkler systems may also be activated manually.

Fire Blankets
Fire blankets are used to control small fires and are commonplace in kitchens as they smother a fire. They may also be wrapped around someone if their clothing is on fire. Fire blankets must conform to British Standards.

Fire Extinguishers
Fire extinguishers are one of the most common types of equipment for fighting fire. Different types of extinguishers are available for fighting different types of fires. Extinguishers should ONLY be used if you have been trained to fight fires and it is safe to do so.

Fire Alarm
Warning other people about fire is one of your key responsibilities. The sooner you do this, the better, as it gives everyone more time to get out of the building.

Smoke Detectors
Smoke detectors are relatively common devices, designed to detect fires in buildings. There may be smoke detectors in your organisation, depending on the size and type of work that is carried out.

Fire Door
In many organisations, fire doors play a key role in slowing down the speed a fire takes hold.
