Description
We've all seen fire hydrants for years and few of us pay any attention to them until we see a fire fighter connecting one or several of the fire trucks hoses to the fire hydrant to fight a fire.
For 95% of the population there are two basic types of fire hydrants - public and private. Public fire hydrants are owned by the municipality and private fire hydrants are owned by the person or company on whose property they rest upon.
Fire Hydrant Operation
When a fire fighter needs to access a fire hydrant a hose is attached to the fire hydrant, then the valve is opened to provide a powerful flow of water. This hose can be further attached to a fire engine, which can then use a powerful pump to boost the water pressure and possibly split it into multiple streams.
The hose may be connected with a threaded connection, instantaneous "quick" connector. Care should be taken not to open or close a fire hydrant too quickly, as this can create a water hammer which can damage nearby pipes and equipment.
When a firefighter is operating a hydrant, appropriate personal protective equipment, such as gloves and a helmet with face shield, are typically worn. High-pressure water coursing through a potentially aging and corroding hydrant could cause a failure, injuring the firefighter operating the hydrant or bystanders.
To prevent casual use or misuse, the hydrant requires special tools to be opened, usually a large wrench with a pentagon-shaped socket. Vandals sometimes cause monetary loss by wasting water when they open hydrants. Such vandalism can also reduce municipal water pressure and impair firefighters' efforts to extinguish fires
