SAND AND WATER BUCKET

It is the oldest method in which bucket is filled with sand and water to stop fire.

These buckets are low technology methods of fighting small fire.

They are hung on dedicated fire stand and placed in prominent position.

LIMITATIONS

It is can be used for small fire only. Need more man power to control fire. Water and sand need to be filled again and

again.

FIRE HYDRANT Fire hydrant system is

capable of extinguishing fires of large sizes in small time if it is handled by trained personnel.

Fire hydrant throw water with great pressure.

Fire Hydrant system is designed in rings so as to receive water at a place via two routs.

They are divided into four categories 1 Light hazard2 Ordinary hazard3 High Hazard (Class A) and High Hazard (Class B).

LIMITATIONS-•This need to be handle by trained person.•Special equipments are require to open hydrant.

FIRE HOSE Fire hoses are high

pressure hose it is used inside the building or can be used outside .

They are attached to fire hydrant or plumbing system.

Pressure of fire hose is 8 to 20 bar.

SPRINKLER To overcome the limitation

of hydrant sprinkler are used

They are heat sensitive when heat reaches it open up and spray water.

These are used in factories and large complexes.

TYPES OF SPRINKLERS frangible bulb type

fusible link type

LIMITATIONS

The detection is relatively slow.

It can not be used on tank fires.

It can not be use on Electrical equipment.

WATER SPRAY To overcome the

limitations of sprinkler water spray are used.

There response much faster then sprinklers.

They are used in exposure protection.

Water spray in transformer

Types of water spray system-•High Velocity water Spray System(HVWSS) •Medium Velocity Water Spray System. (MVWSS)
