Class C

Flammable Gases are the reason for the fire

Class D

Fire caused by the combustible metals like sodium, potassium, magnesium

Class F

Fire caused by cooking oils such as vegetable fats.

Different mechanisms and methods are being used to tackle different sorts of fire so that it can be controlled as soon as possible. Different types of fire extinguishers are made by different fire extinguisher distributors. Some of commonly used extinguishers are as follows.

Water Extinguishers

They are generally more useful when fire is caused by solid materials that are class A fire. There are four types of water extinguishers.

1.      Water jet

2.      Water Spray

3.      Water extinguisher with additive

4.      Water mist or fog

This cannot be used when fire is due to electrical short circuiting.

Foam Extinguishers

They are generally used for class A or Class b Fires. It seals the surface of flammable liquid so that fire can not reach it and we can control fire. They cannot be used on free flowing liquids fire.

Powder Extinguisher

Powder extinguishers are multi tasking extinguishers as they can be used for most of the cases like class A, Class B, Class C. This method is used as a last option as they cause loss of visibility and agents used in this are quite harmful for everyone.

Carbon dioxide Extinguisher

This is widely used at offices where electrical equipments are being used. They are easy to operate and do not have any adverse effects.

Fire Blankets 

This is one of the most important equipment, but unfortunately, it is considered the least important. Whenever fire happens due to kitchen oils, then having fire blankets can help one to evacuate the building with utmost care. So it is recommended to have as many fire blankets as possible in the house with respect to the number of your family members. They are used when a person catches fire as it helps in cutting the air supply so that fire can extinguish on its own.

Wet Chemical Extinguishers

They are commonly used for class F fire. As the chemicals react with the oils and foam soap like solution so that fire won’t get any medium to spread.

 

 So at last fire is a deadly weapon in order to control it we have to know about its cause and only then it can be treated properly and extinguished as soon as possible.

Essential Role of Four-Way Fire Brigade Connections in Firefighting Operations

Image
  A Four-way fire brigade connection, also known as a four-way Siamese connection, is an essential component of a fire protection system used by firefighters to supply water to a building's fire sprinkler or standpipe system. These connections are typically found on the exterior of buildings and provide a point of connection for fire hoses.  Importance of Four-way fire brigade connections in firefighting These connections serve as a critical component of a building's fire suppression infrastructure and provide several important functions: Increased Water Supply:  Firefighters need lots and lots of water to fight fires. With four-way connections, you can connect more than one hose to one water source to get more water flowing. This is especially important if you're dealing with big fires that need much water to fight and put out.

Hose Reel Drum and Hose Pipe Applications

A hose reel drum is a spindle with a cylindrical shape composed of rubber, metal, fiberglass, or plastic that is used to keep a hose pipe in place. Hose reel drums come in various sizes depending on where they will be used (garden, construction, or industry). A flexible tube used to convey water from one area to another is a hosepipe. Hose reel drums and hose pipes are required in every structure. A fire hose reel is intended as a quick-response tool for putting out small flames. Anyone in the building, or the wider public, will likely assault it first.  For class A fires, hose reels are excellent (paper, textiles, wood, plastics, and rubber). When there is an electrical fire, it should not be used. Use of a Fire Hose Reel Drum The hosepipe is kept in hose reel drums. It can be either permanently installed on a wall (wall-mounted) or movable (portable) (attached to a truck). They give nearly endless water since they are connected to the main water supply 24 hours a day, 365 days a ...
