1-inch hose with 1-8 NH NFPA threads (NFPA 1963 requirement; a.k.a. "Chemical Hose Thread" and "Booster Hose Thread"; the chemical hose thread term likely originates from its use on chemical fire engines, an early firefighting device used from 1872 until the 1930s that used a combination of bicarbonate of soda and sulfuric acid to force water ...
The gusset plate is usually painted to match nearby steel and fixtures and to give it an extra layer of protection. [2] Occasionally gusset plates are made from copper or aluminum, but only with small structures that do not require much support. The copper and aluminum gusset plates also provide a more attractive finish for exposed structures. [2]
Attack hose is a fabric-covered, flexible hose used to bring water from the fire pumper to the nozzle. This hose ranges in nominal inside diameter from 1.5 to 3 in (38 to 76 mm) and is designed to operate at pressures up to about 400 psi (2,760 kPa). The standard length is 50 ft (15.24 m). [12] Supply and relay hoses.
A. Adapter. Fitting for connecting hose couplings with dissimilar threads but with the same inside diameter. [1] See also reducer, increaser, double male, double female. May contain combinations, such as a double-female reducer. Adapters between multiple hoses are called wye, Siamese, or distributor, which see below.
A hose coupling is a connector on the end of a hose to connect (or couple) it with another hose or with a tap or a hose appliance, such as an irrigation sprinkler. It is usually made of steel, brass, stainless steel, aluminium or plastic. Due to the great variety of the designs and the number of countries in which they were created, it is ...
Standpipe (firefighting) A standpipe or riser is a type of rigid water piping which is built into multi-story buildings in a vertical position, or into bridges in a horizontal position, to which fire hoses can be connected, allowing manual application of water to the fire. Within the context of a building or bridge, a standpipe serves the same ...
Fire sprinkler system. A glass bulb type sprinkler head will spray water into the room if sufficient heat reaches the bulb and causes it to shatter. Sprinkler heads operate individually. Note the red liquid in the glass bulb. A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate ...
This method of storing hose is designed for rapid deployment of a hose line to attack a fire. In this manner, the hose is stored perpendicularly across the fire apparatus, usually above or adjacent to the pump panel, instead of the usual parallel storage in the rear. This allows the firefighter to pull the hose in the direction of the fire ...
