Which is a guideline for loading hose into an apparatus hose bed? b. Keep flat sides of hose in the same plane when two sections of hose are connected.
When loading hose into the hose bed on an apparatus, hose should be: loaded loose enough to fit a gloved hand between the folds. Hard suction hose is commonly used: for drafting from a static water source.
Intake Hose — Hose used to connect a fire department pumper or a portable pump to a nearby water source; may be soft sleeve or hard suction hose. Figure 4.9 This driver/operator is using a short section of LDH to connect the pumper and hydrant.
Which preconnected hose load is designed to be pulled by one person and must be completely removed from the bed before deploying the nozzle end? Triple layer load.
~Flat load is the easiest to load. ~Best way to load large-diameter hose. ~Hose load for a LDH should be started 12 to 18 inches from the front of the hose bed.
The flat load is a drag load designed to be stretched from either side of the apparatus by the crosslay. By properly placing two sets of pulling loops on each side of the apparatus with the nozzle in the middle, you have the option of which side of the apparatus from which to pull the hose, depending on the situation.
NFPA 1962: Standard for the Care, Use, Inspection, Service Testing, and Replacement of Fire Hose, Couplings, Nozzles, and Fire Hose Appliances.
The two most common causes of hose damage are: excessive pressure and water hammers. A distinct advantage of the minuteman load over the flat load is that: the entire load can be advanced without dragging.
Maximum length for hose service test layout is 300 feet and all hose in a single layout must be of the same internal diameter and test pressure capacity.
What determines which hose load is carried on the pumper? The type and size of fires expected to be encountered.
The twin donut roll creates a compact roll that is easily transported. The self-locking twin donut roll adds a built-in carrying loop for the hose.
Supply fire hose shall be service tested to a minimum of 200 psi (13.8 bar or 1380 kPa) or a pressure not to exceed the service test pressure marked on the hose.
It can be done by laying both ends of the hose side by side. Then, roll the hose up from the fold side, making the hose into two side by side rolls, according to Prichard-Murray Volunteer Fire Department in Idaho. The end fold will have a decreased diameter, making it more compact and easier to carry.
- Combination load - Used to split hosebeds, baffle in the middle, connect couplings. Allows you to make a forward lay, disconnect the couplings and then do a reverse lay back to the water source. - Combination lay - Any number of ways to lay multiple supply hose with a single engine.
One such load is the “Minuteman” hose load, which is designed to aid the firefighter in getting the initial attack line in place with ease for any type of operation, be it residential, commercial, or high-rise.
NFPA 24 helps ensure water supplies are available in a fire emergency, with detailed requirements for the installation of private fire service mains and their appurtenances supplying private hydrants and water-based fire protection systems.
NFPA 1001, Standard for Fire Fighter Professional Qualifications identifies the minimum job performance requirements for career and volunteer fire fighters whose duties are primarily structural in nature.
Which action should be avoided when service testing fire hose because it can cause damage to the fire hose? Testing the hose in an area with rocks and debris. When service testing a hose, it is necessary to: have access to a water source that is sufficient for charging the hose.
