Objectives:

Define what a fire hydrant is.

Describe the two primary types of fire hydrants.

Discuss the design, location, installation, parameters, and recognition of fire hydrants.

Explain how fire hydrants operate.

Outline the procedures for inspecting and maintaining fire hydrants.

Demonstrate the operation, inspection, and maintenance of fire hydrants.

What is a Fire Hydrant?

A fire hydrant is a critical component of a firefighting water supply system. It consists of a network of pipes connected to a high-pressure pumping system, designed to provide a reliable and abundant water supply for firefighting operations. Fire hydrants are typically connected to a water main via a branch or T-piece. The hydrant itself is housed in a chamber or pit, often constructed from brick or another durable material, and is covered with a hinged cast iron lid.

Types of Fire Hydrants

Fire hydrants are primarily categorized into two types:

Dry Riser Hydrants

Description: Dry riser hydrants are designed for use in climates where temperatures can fall below freezing. These hydrants feature a valve at the base of the hydrant, below the frost line, which prevents the hydrant from freezing. The barrel of the hydrant is emptied after each use to avoid ice formation.

Wet Riser Hydrants

Description: Wet riser hydrants are used in regions where freezing temperatures are not a concern. These hydrants always contain water in the barrel and are typically ready for use immediately.

Design, Location, Installation, and Recognition

Design of Fire Hydrants

Considerations: When designing a fire hydrant system, several factors must be considered:

Required water flow for effective firefighting.

Number and size of hose connections.

Current and future fire apparatus configurations.

Clearance issues and operational characteristics.

Available pressure in the water lines.

Climate conditions.

Compliance with regional standards for coupling threads.

Visibility and accessibility of the hydrant.

Location of Fire Hydrants

Placement: Fire hydrants should be installed at regular intervals, with deviations based on specific site requirements. Adequate hydrant placement ensures sufficient coverage for required fire flows and high-risk areas. Hydrants must be positioned at a safe distance from structures and should not be obstructed by fences, walls, or parked vehicles.

Installation of Fire Hydrants

Coordination: Proper installation requires coordination among various parties to ensure that hydrants are not obstructed by utility poles, sewer lines, or other encroachments. Equipment or facilities should be kept at a safe distance from the hydrant body, and landscaping must not obstruct the hydrant.

Installation Parameters

Specifications: Hydrants should have a minimum of two delivery outlets, with a pressure range of 3-5 bar. Each outlet should feature instantaneous female couplings and preferably a separate shut-off valve. The main hydrant line should have a minimum diameter of 4 inches, be metallic if possible, and include a drainage mechanism.

Fire Hydrant Recognition

Visibility: Fire hydrants should be easily identifiable by both firefighting personnel and the public. Standard color coding helps distinguish them, and non-municipal hydrants may be painted in different colors for differentiation. Hydrants must be marked with visible colors and indicators if they are permanently or temporarily out of service.

Fire Hydrant Operation

Turning On a Fire Hydrant

Procedure:

Remove the blanking cap from the outlet.

Ensure other outlet caps are secure.

Attach the hose to the hydrant outlet.

Use a hydrant wrench to check the opening direction of the valve.

Follow instructions from the officer or pump operator to start the water flow. Turn the wrench to fully open the valve slowly to avoid pressure surges.

Turning Off/Shutting Down a Fire Hydrant

Procedure:

Close the hydrant’s valve slowly using the wrench.

Disconnect the hose and replace the outlet’s blanking cap.

Inspection and Maintenance of Fire Hydrants

Inspection

Frequency: Hydrants should be inspected physically and operationally at least once a year.

Checklist: Ensure valves, blanking caps, couplings, and mainlines are functioning correctly. The hydrant should be free from obstructions like tall grass or debris. Inspection records should be documented for reference.

Maintenance

Tasks: Regular maintenance includes checking and replacing damaged gaskets, lubricating rusted parts, and repairing or replacing faulty valves and components.

By understanding and adhering to these guidelines, fire hydrants can be effectively maintained to ensure they are operational when needed, contributing to effective firefighting and enhanced safety.
