FIRE HYDRANT SYSTEMS

Fire hydrant systems are used by fire authorities as an access point to connect fire hoses and gives them the ability to be able to expel large amounts of water at one time to extinguish flames. Like all fire safety equipment, regular testing, inspection, and maintenance must be conducted to ensure that the system is ready for use at the instance of an emergency.

What components do you need to have a working fire hydrant system?

In order to have a working fire hydrant system there are several components that should be in place:

Available water supply and storage

In order for a fire hydrant system to operate correctly, there needs to be an adequate amount of water and storage. This can come from a streets main, a static tank or a dam. There will need to be some form of automatic replenishment for any of the water that is used by the system, and any that evaporates or leaks. When considering a hydrant system, also consider the amount of water that will need to be supplied and whether or not it would be enough to extinguish a large fire.

Valves and connecting pipes

There are a number of pipes and valves involved in this system, and they should allow water to flow from its reservoir to the hydrant without any restrictions. The size of these pipes and valves will be determined based off of the water supply requirement and the hydraulic analysis in conjunction with the Australian Standards guidelines from AS2419.

Fire Brigade Booster

Having this will allow the fire brigade to boost the pressure of a hydrant system. In most installations, the booster is located inside a cabinet and reports any pressure specifications in accordance with the hydrant system.

Booster Pumpset

The booster pump-set can be used where there may be some limitations and more pressure is needed to supply the system with enough water. The pumps can be powered by an electric motor or diesel engine, the exact model will depend on the requirements of your location.

Hydrant Valve

This connects the fire hose to the water supply and utilises a valve to access the water when needed. The location of the hydrant should be based the Australian Standard AS2419, which will state that the system needs to be in an easily accessible location to be able to be used to extinguish fires quickly.

Fire Hose

Depending on your buildings design and the accessibility of your hydrant, there may be some emergency situations where a lay flat fire hose will need to be placed near the hydrant. These fire hoses allow for quick connection and extended reach if required.

Block Plan

The block plan is generally located in the booster cabinet, pump room, and fire control room. This plan includes a diagram that clearly illustrates the location of any fire hydrant water supplies and other equipment along with their individual capacities where applicable. Other important information that should be included but not limited to is the year of installation, any contractor names, etc.

Frequently encountered faults include:

  • Leaking valve.
  • Being hit by a vehicle.
  • Misuse or vandalism.
