Types of Fire Hydrants: Wet Barrel, Dry Barrel, Wall Mount & More

A fire hydrant is essential in providing water for firefighters to extinguish fires. It allows for the speedy control and extinguishing of fire outbreaks. Fire hydrants are fixed at commercial complexes, housing societies, industrial belts, and public places. These types of fire hydrants are easy to access water during emergency cases.

Fire hydrants, in Delhi NCR, are important for adherence to fire safety norms. As part of the fire protection plan, it is compulsory in buildings. As there is an increasing number of high-rise buildings and places for production, the significance of fire safety measures is growing. Fire hydrants are important in ensuring that people and property are safe.

Main Types of Fire Hydrants

There are principally two types of fire hydrants: the wet barrel and the dry barrel hydrant. They are chosen depending on the climate, how they will be used, and local safety requirements.

Wet Barrel Hydrants

In this, water is always found in the barrel. These types of fire hydrant systems are perfect for areas that experience warm weather and no danger of freezing. There is a valve in every outlet so that one can control each. The wet barrel hydrants are simple and speedy to operate. They also require little to no maintenance and are powerful in cases of emergencies.

Dry Barrel Hydrants

Dry barrel hydrants are made for cold regions. The barrel remains dry before the valve is opened. This is to ensure that water does not freeze within the hydrant. The frost line is placed below the valve seat in order to avoid ice blockages. These types of fire hydrant systems are commonly used in commercial and industrial areas of Delhi NCR. They provide safety and stability during severe winters as well.

Subtypes Based on Mounting and Use

There are also four different classes of fire hydrants based on how and where they are mounted. These types have a variety of needs in urban and industrial areas.

Wall Mount Hydrants

Wall-mounted hydrants are fixed directly onto the walls of buildings. They are often seen in basements, parking areas, and industrial sheds. These types of fire hydrants are easy to access during indoor emergencies. Their compact design saves space and is suitable for indoor use.

Underground Fire Hydrants (Flush Type)

Underground or flush hydrants are kept hidden under covers made of metal. They are activated by taking the lid off and fitting a valve key. These types of hydrant systems are used in places where appearance and space are an issue, like sidewalks or roads. They offer fire protection while not interfering with the surroundings as far as visibility is concerned.

Pillar-Type Fire Hydrants

These types of hydrant systems are freestanding upright hydrants. They are easily located and accessible in emergencies. Pillar hydrants are frequently used in open spaces for public use, commercial complexes, and parks. Their high structure allows them to be seen from a distance.

Importance of Fire Hydrants in Fire Safety

Fire hydrants offer immediate access to water in times of emergency. This makes it easy for firefighters to control and put out fires in a shorter time. They assist in minimising fire damage to property and life. They are important in sustaining massive firefighting exercises.

In relation to fire safety, having an adequate fire hydrant is important. Proper installation of a hydrant system complements the whole fire suppression plan of a building. When construction is tight, as in Delhi NCR, hydrants are a lifesaver from major disaster occurrences.

Components of a Fire Hydrant System

The various parts of a comprehensive system of fire hydrants are important. Every part has an effect in making the system effective in case of emergencies.

Hydrant Valve

This is a gate that regulates the outflow of water from the hydrant. It enables firefighting teams to control water pressure and direction.

Fire Hose and Hose Reel

The hose takes the water from the hydrant to the fire. The hose reel is used to store and uncoil the hose quickly in case of an emergency.

Branch Pipe and Nozzle

These elements are fitted on the hose. They help guide the direction of water flow to the fire using pressure. Nozzles can be adjusted to change the spray according to requirements.

Fire Pump and Pressure Control System

The pump ensures that there is pressure in the system. It provides a uniform flow even in skyscrapers. The pressure control unit helps prevent damage from overpressure.

Water Tank and Pipe Network

The water tank holds water for the hydrant system. The pipe network interlinks all hydrants and ensures regulated water distribution. A reliable network ensures that water is available when needed.

Such a setup of all these parts ensures that the types of hydrant systems are functional and reliable in the event of an emergency.
