In our last post, we explored some of the basic fire rig apparatus and equipment checks. These straightforward evaluations can ensure safety in the field and equip the team with the necessary safety and functionality equipment. In addition, share this information with your clients to provide some insights into the right type of fire hoses for the job. Even more importantly, secure their entire operation with a Firefighter General Liability policy.
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. Selecting the incorrect one from the start can cause delays in fire suppression and exhaustion.
While firefighters might slip into a familiar routine, and one that’s comfortable, repetition and familiarity might be the first mistake with a negative domino effect. The hose coupling diameter of a 1½- and a 1¾-inch are the same, they only differ with the diameter of the hose jacket. So, when there is water flowing through a 1¾-inch hose line, it still has to travel through a 1½-inch coupling at every 50 or 100 feet; this small reduction in the hose coupling diameter adds some friction loss overall, but the amount is inconsequential in comparison to the amount of water that can be delivered at a lower operating pressure with a 1¾-inch hose line, says Fire Rescue 1.
As bigger fires naturally require more water to eliminate, firefighters should be accustomed to easing all hose sizes. With a 2 ½ inch nozzle, the average water delivery rates are between 200 and 325 gpm. If a small hose is easier to use for a firefighter, however, then the job would just be extended, handicapping the crew rather than helping them.
