Inside the structure of a building a standpipe is a collection of piping, hose connections, valves, as well as accompanying equipment. Their sole purpose is to help extinguish a fire to protect lives and property. The positioning of the hose connection allows water to be discharged in spray patterns or streams once the hoses as well as nozzles are connected.
The standpipe system also has numerous outlets located on each floor of a building. This enables firefighters to reach all the areas in a building. However, they are designed differently to accommodate various fire safety needs of property owners and firefighters. Read on to learn about the different classes of standpipes systems.
These systems are restricted for use by professional firefighters as they release water under high pressure that may be hard for an inexperienced person to control. Their outlets are usually installed within building stairwells.
Firefighters usually carry a unique hose to attach to class I standpipe connections. In most places, you can fit a 2.5″ hose. However, in New York and San Francisco, you can fit a 3″ hose to your class 1 standpipe.
They are common on hallways of buildings, mostly accommodating a 1.5″ hose. They are easy to operate and can be accessed and used by anybody. However, property owners are increasingly shunning them. There has been a heightened safety risk of inexperienced people trying to use them to put out fires and getting hurt in the process. As a result, they mostly exist on old buildings, with new building owners preferring domestic fire sprinklers.
This is a hybrid of class I and Class II standpipe systems. They have permanently fixed 1.5″ hoses for use by inexperienced firefighters. And 2.5″ hose connections where professional firefighters attach their hoses. Some Class III systems have 2.5″ connections and reducers with 1.5″ hoses permanently attached. But some do not include the permanent 1.5″ hose.
