Automatic Fire Extinguishers
In some situations, it may be a clever idea to employ automatic fire extinguishers which are triggered when a certain temperature is reached, or flame or smoke is detected. There are modern fire protection devices that can be used as an alternative to fire sprinkler systems, especially in cases where water damage would be costly. Today’s technology makes automatic fire extinguishers reliable and a sensible preference.
Automatic fire extinguishers are extremely efficient – they discharge automatically once the fire reaches a certain temperature and extinguish the fire safely without any need for user intervention.
An automated system works independently with a method of detection, a trigger for activation and an agent to suppress the fire. The working mechanism is similar to that of a manual fire extinguisher, with the major difference being the automatic system contains a quartzoid bulb instead of a squeeze grip operation. The quartzoid bulb contains heat-sensitive material that expands when it gets hot. As it reaches the pre-determined temperature the bulb bursts and the extinguisher is discharged.
The most common automatic extinguishers are Dry Powder and Clean Agent types.
Dry Powder extinguishers are a very good choice to protect engine compartments such as in boats or large vehicles. Only one unit should be installed in any one compartment in order to provide the total protection required for that area. These fire extinguishers offer protection against class A, B, and C fires and are also safe to use on electrical fires.

Clean Agent extinguishers are a very good choice to protect computer rooms, high-value assets or other delicate instruments from fire, as they leave behind no harmful residue. Only one unit should be installed in any one compartment in order to provide the total protection required for that area. The unit required is determined by the gross volume of that compartment and is based on the volumetric coverage of the different units.
