Fire Hose Reels are easy to use and provide a virtually unlimited supply of water, as they are connected to the mains water supply, and should extend for approximately 35 metres.
How long is a section of hose?
The most common hose length is 50 feet, so that is the measurement we judge our travel distances against: how many lengths of hose it will take to cover a certain distance. All of this matters not only to have a chance at a successful fire attack but to make sure your hoseline is pumped correctly.
How long is a hose on a fire engine UK?

45mm hose – at 23m in length this is the standard hose, commonly used in house fires.
What is the maximum length of a fire hose reel?

How long does a fire hose reel last?
Fire Hose reels if maintained and looked after can last up to 10 years before needing replacement. When fire hose reels are tested 6 monthly we are checking for presence of water and to ensure that it has the correct flow rate of 0.33 Litres per second (OR 1 litre in 3 seconds).
Where should a fire hose be located?
The fire hose reel or reels, need to be located within a design such that the occupant can reach a fire in any part of the building. The maximum length of hose allowed for this calculation is 36m with a 4m spray from the nozzle. It is system coverage that will determine if internal hydrants are required.
What are the different sizes of fire hose?
The standard three sizes of hose lines are 1½, 1¾ and 2½ inch. Depending on the size and severity of the fire, hose line requirements vary to get the job done efficiently.
How do you measure a fire hose?
How to determine which size hose you might have.
- Check the female coupling for numbers like 1.5 or 2.5.
- Measure the inside diameter of the male coupling. Do not measure the female coupling.
- Check for numbers stenciled on the hoses.
- Do not measure the hose laying flat.
How is fire hose measured?
The standard three sizes of hose lines are 1½, 1¾ and 2½ inch. Depending on the size and severity of the fire, hose line requirements vary to get the job done efficiently. The hose coupling diameter of a 1½- and a 1¾-inch are the same, they only differ with the diameter of the hose jacket.
Are fire hoses fireproof?
It seems counterintuitive: fire hoses – the key firefighting tool used by firefighters across the country — are not fire-resistant. Yet the hoses, usually made from woven cotton and rubber, can burn through when they are not charged with water, putting firefighters in grave danger.
How far from an exit must fire hose reels be located?
4 m
Fire hose reels must be located within 4 m of an exit, except that a fire hose reel need not be located adjacent to every exit, provided system coverage can be achieved.
What is the maximum length of the connected hose during hose testing?
T. Maximum test length for all hose line sizes shall be 300 feet.
What is the standard length of a fire hose?
The standard length is 10 ft (3.05 m). Another suction hose, called a soft-suction hose, is actually a short length of fabric-covered, flexible discharge hose used to connect the fire pumper suction inlet with a pressurized hydrant. It is not a true suction hose, since it cannot withstand negative pressure.
How long is the typical fire hose?
The length of fire hoses often varies, but standard hose reels have a maximum extension length of 118 feet (36 meters). A hose reel with a diameter of between 0.5 inches (13mm) to 0.75 inches (19mm) should accommodate 11 ounces (0.33 liters) of water in a fire fighting situation.
What is the diameter of a fire hose?
Fire hoses come in a variety of diameters. Lightweight, single-jacket construction, 3⁄4, 1, and 11⁄2 inch diameter hose lines are commonly used in wildfire suppression applications. Heavy duty double, double-jacket, 11⁄2, 13⁄4, 2, 21⁄2, and on occasion 3 inch lines are used for structural applications.
What is the flow rate of a fire hose?
Flow Capacities for fire hose. That is 50 psi for overcoming the friction loss in the hose and 100 psi to properly operate the nozzle. When sending water through a 2 1/2″ line at 100 gpm it takes about 2 1/2 psi per 100 ft. of hose. At the same flow rate, 500 ft. of hose will require 13 psi to move that volume of water.
