Hi and welcome to my site realfireman.blogspot.com.

Today we are going to discuss about application of automatic fire extinguisher.

Portable Fire Extinguishers play a key role in fire protection but rely heavily on visual identification of the fire or a physical response to a fire alarm to be effective. There are many applications where these sensory fire detection and alarm devices are ineffective or provide a limited safeguard against accidental fires. For example if the fire starts in an enclosed unmanned compartment such as an engine room or where the background noise may drown out a conventional alarm the fire may not be detected until it is very late. Another high-risk scenario is when equipment may be running 24/7, computer server rooms are typical examples. If a fire starts when the facility is unmanned then there is a big risk that the fire may remain undetected long enough to go out of control. 

So first of all we should know what is automatic fire extinguisher?

An automatic fire extinguisher is a device permanently installed at a facility and have glass which breaks when certain temperature is reached in case of fire and extinguishes fire automatically without any attendant or fire fighter.

Automatic fire extinguishers are designed to counter these risks by providing a fixed permanent fire fighting unit that operates automatically at an early stage in the fires development. Automatic Fire Extinguishers are permanently installed immediately adjacent and directly above the fire risk with the discharge nozzle directed vertically downwards. Each unit is fixed with a heat activated glass bulb sprinkler head. The bulb is designed to break automatically at a fixed temperature usually between 60 and 70 degrees centigrade to automatically release the seal on the extinguisher enabling full discharge the suppressant. There are two common types of Automatic fire extinguishers in a range of sizes to suit increasing compartment sizes. ABC Dry Powder Automatic extinguishers are used in engine compartments, generator and industrial plant rooms, switch gear rooms, boats and vehicles. Dry powder is effective at combatting Class A, Class B and Class C fire risks. FE-36 or Clean Agent fire extinguishers were developed as a replacement for halon extinguishers and work by replacing the oxygen in the ambient air with an inert noncombustible gas that has the effect of quenching the flames. Their great advantage over Dry powder is that after discharge the gas dissipates leaving no harmful residue and without causing damage to sensitive electronic equipment, or other high value assets. Clean agent Automatic extinguishers have applications for boat engine compartments, sensitive electronics, plant and machinery, laboratory clean rooms, storage rooms in museums and art galleries and data storage areas. In fact any enclosed unmanned location where high value or high fire risk assets require round the clock fire protection. Automatic extinguishers, are intended for use in enclosed compartments. Each unit is rated on the ground of the maximum volume of space a single suppression unit can cover so it is important that you comply with the recommended compartment volume and if necessary try to install a sufficient number of extinguishers or a bigger unit to give adequate protection.
