What is the hose?

A hose is a thick, high pressure pipe used to carry water or other fire extinguishing media (such as foam) to the fire to extinguish it. The usual pressure of a fire hose can vary between 8 bar to 20 bar. If more than this, the fire hose is likely to explode.

Types of hoses

There are usually three types, like Suction hose, Delivery hose, Hose-reel-hose. Again there are two types of Suction hoses, like: Partially embedded, Fully embedded. Again there are two types of Delivery hose, like Percolating, Non-percolating.

Suction hose

It is laid down on the suction side of the pump (inlet side). The pressure in the pipe becomes lower than the atmospheric pressure. That is why the suction pipe should be strong.

Partially embedded

In this type of hoses metal wires not fully embedded.

Fully embedded

In this type of hoses metal wires fully embedded which make it more strong.

Delivery hose

It is laid down from the delivery side of the pump (outlet). The pressure of water passing through is always greater than the atmospheric pressure.

Type of delivery hoses

Percolating hose

The hose in which flux and cotton used more than rubber due to which the hose gets wet when water passes through it, due to the seepage of water. It used mainly in a forest fire because it’s seepage character prevents it to burn. But the pressure of water reduces when we carry water to long-distance due to water seepage.

Non-Percolating hose

This is made up of reinforced jacket of nylon yarn with inner lining of vulcanized rubber.


A fire hose reel is a first attack piece of fire-fighting equipment. It is designed to be used as a quick response method by any member of the general public for fire fighting fires in their early stages. With a standard fully extended length of 36 meters.

Dimension of hoses

DELIVERY HOSE45, 70 & 90 mm
SUCTION HOSE75, 100 & 140 mm
HOSE-REEL-HOSE19 & 25 mm

Material used to make hoses

  • Flax – It has greater strength and durability with high absorbent qualities, but when wet, increases the weight of the hose.
  • Cotton – It also has high absorbent qualities, but it doesn’t take much time to dry.
  • Nylon – It is light in weight and greater strength with low absorbent qualities.
  • Terylene – It is also light in weight and greater strength with low absorbent qualities. It is more flexible than other hoses.

What can damage the hose?

  • Abrasion – If we are dragging the hose regularly on the ground it can damage.
  • Mildew – It is a fungus that can dame the hose if we are keeping the hose in wet condition.
  • Shock & strain – Excessive pressure can also damage the hose.
  • Rubber acid – If we are properly drained the rubber hose, the water in it can be converted to acid after some period, which can damage the hose.
  • Chemicals – Avoid the contact of acid, paint and other corrosive chemicals these can damage your hose.

Methods of stowing hoses

  • The Roll Method
  • Dutch Roll
  • Flakking
  • Figure of Eight
