Most of the warnings have been severe about the dangers that could result if snow isn’t cleared away from fire hydrants. Departments have taken to social media to ask neighbors to help clear the hydrants so firefighters could use them in an emergency. The Huntington Fire Department has decided to take another approach, establishing a competition and a prize. The department said on Facebook that…

Dry Barrel Fire Hydrants are commonly used in regions prone to freezing temperatures. Unlike wet barrel hydrants, the valve in a dry barrel hydrant is located underground, below the frost line, and the hydrant remains dry until it's activated. This design prevents the water from freezing inside the hydrant barrel, making it a dependable tool in colder climates.

However, to ensure safety and operational efficiency, there are specific guidelines that must be followed when operating dry barrel hydrants. Below are the essential safety measures and best practices to keep in mind.

Inspect Before Operation

Before using a dry barrel hydrant, always perform a visual inspection to ensure:

No visible damage or leaks around the hydrant

Caps are intact and secure

No obstructions around the hydrant base or outlets

Inspecting before use can prevent malfunctions and reduce risk during an emergency.

Use the Proper Tools

Always use the correct hydrant wrench to operate the stem nut. Avoid using makeshift tools as they can:

Damage the nut or valve stem

Cause slippage and injuries

Lead to improper operation of the hydrant

Having the right tool is crucial for a smooth and safe opening and closing process.

Open the Hydrant Fully

When operating dry barrel fire hydrants, it's important to open them all the way. Partial opening can:

Cause water to leak into the barrel

Result in freezing and cracking in cold weather

Lead to internal pressure imbalances

Opening fully ensures the valve at the bottom is clear and water can flow unobstructed.

Check for Proper Drainage

After use, dry barrel hydrants are designed to automatically drain any remaining water from the barrel to prevent freezing. To verify proper drainage:

Close the hydrant fully

Remove one of the outlet caps

Place your hand to feel if suction is occurring (indicating water is draining)

If drainage isn’t happening, it could mean the drain valve is blocked or damaged, which requires immediate maintenance.

Never Leave Hydrants Pressurized

Always relieve pressure after using the hydrant. A pressurized hydrant can:

Burst in freezing weather

Cause unexpected discharge if a cap or valve is loosened

Create hazards for nearby personnel

Draining and depressurizing properly helps avoid these dangers.

Monitor for Unusual Noises or Vibrations

Unusual sounds during operation—such as grinding, whistling, or banging—may indicate internal mechanical issues. Vibrations could mean water hammering or unstable flow, both of which are safety risks that should be reported immediately.

Regular Maintenance and Training

Routine inspections & preventive maintenance are essential to ensure that dry barrel hydrants function correctly during emergencies. Also, operators should be trained in:

Safe handling procedures

How to identify common faults

Emergency shut-off protocols

Training helps reduce operational risks and equipment damage.

In Conclusion

Operating dry barrel hydrants requires a clear understanding of safety protocols, proper tools, and careful inspection. By following these guidelines, fire safety personnel and maintenance teams can ensure effective and safe hydrant performance, especially in cold climates where reliability is critical.
