A fire extinguisher can be defined as an active or ready fire protection device which is used to control or extinguish small fires. It is often used in sudden emergency situations. Fire extinguishers are not intended for the use of an out of control fire such as the ones that have greatly spread over the building, it can greatly endanger the user. The fire extinguisher consists of a hand held pressure vessel which is cylindrical and contains an agent that can anytime be discharged to reduce, suppress or extinguish fire. There might be fire extinguishers that are made in a pressure vessel which is non cylindrical but are usually less common these days.
Fire extinguisher Singapore are usually divided into two types; the cartridge operated fire extinguisher and the stored pressure fire extinguisher. Both are used differently and are both helpful when it comes to fire safety measures. Fire extinguishers can be regarded as the holy grail of fire safety due to its unique abilities and efficiency in fire control. I believe fire extinguishers have proven to be rather more helpful than water as the compound used in fire extinguishers do not support burning; it completely shatters or covers the threat immediately.
In current research analysis I have noted that fire extinguishers have very unique features that why it is regarded as the holy grail of fire safety. These features include:
An aqueous fil forming foam (AFF) which is used on either A and B fires and vapor suppression. The commonly used type is the foam extinguishers. The body of the extinguisher is charged with mild plain water thereby discharging the mixed pressure foam that is concentrated thus squeezing up the lever. These specific extinguishers receive double ratings of pre-mix models of 40-B instead of a 20-B and are considered to be obsolete as its parts refill the cartridges to full amount.
Alcohol resistant aqueous film forming forms- they are used in fires fuels that contain alcohol in it. It forms a thick membrane between the foam and the fuel preventing alcohol from completely breaking down the blanket foam.
Film forming fluoroprotein also known as FFFP- this one contains natural proteins obtained from animal by products together with synthetic film forming agents which create a foam like blanket that is a heat resistant. It also works well on alcohol based fuel fire caused in accidental circumstances.
Artic fire- this is a substance in form of liquid fire extinguishing agent that mainly emulsifies by cooling heated objects or materials faster than water or ordinary foam. It is effective in classes A, B and D. used mainly in steel industries.
FireAde- It is a foaming agent that suppresses or emulsifies burning liquids and cools off the non-flammable. It its very helpful in fire suppression.
In conclusion fire extinguishers are considered to be the very holy grail of fire safety due to its very features. Personally I would prefer to use a fire extinguisher as my safety kid during the prevention of fire.
