The main purpose of the fire department pumper is to provide water at a adequate ($$$$$$) for fire streams.
Pressure
NFPA 1901 contains the requirement for pumper designs. The standard specifies that the minimum pump capacity for these vehicles is ($$$$$),
750 gpm
Or pumps larger than 750 gpm, standard pump capacities are found in increments of ($$$$).
250 gpm
Some fire department combine the functions of a rescue company with a fire department pumper. These apparatus are commonly referred to as ($$$$$$).
Rescue pumpers
Although they can be equipped to flow plain water on class A fires, most industrial foam pampers are primarily intended to produce large quantities of foam solution to attack ($$$$$$) fires and suppress vapors in spills.
class B
Industrial foam pampers are built to the standards provided in ($$$$$$$).
Chapter 11 of NFPA 1901
Most industrial foam pump ares have a large foam concentrate tank on board. These tanks range from ($$$$$) gallons.
500 to 1500
The most common size foam tanks for municipal fire apparatus range from ($$$$$$) gallons
20 to 100
Elevating water devices usually range in height from ($$$$$).
50 to 100 feet.
Specific requirements for the design of initial attack apparatus are contained in ($$$$$).
Chapter 6 of NFPA 1901
All thought they are not designations that are cited in the standard, manufacturers and fire departments typically use two categorical descriptions for initial attack fire apparatus:
Mini pumpers
Mid pumpers
Smaller, quick attack pumpers known as ($$$$$), are designed to handle small fires that do not require the capacity or personnel needed for a larger pumper.
Mini pumpers
Mini pumpers are most often mounted one one ton chassis with custom made bodies or modular units. Most of them have pumps with a capacity no larger than ($$$).
500 gpm
In some departments, pumping apparatus slightly larger than mini pumpers and often meeting the quire nets of class A pumpers are called mid pumpers or ($$$$$$$$)
Interface engines
Mid pumpers are built on chassis usually over ($$$$$).
12000 pounds GVW
Mid pumpers are routinely equipped with pumps as large as ($$$$$$)
1000 gpm
($$$$$) known as WATER TENDERS or TANKER! Are widely used to transport water to areas beyond a water system or to area where water supply is in adequate.
Mobile water supply apparatus.
Specific requirements for MOBILE WATER SUPPLY APPARATUS are found in ($$$$$$)
Chapter 7of NFPA 1901
The size of the water tank specified on mobile water supply apparatus depends upon a number of variables:
Terrain
Bridge weight limits
Monetary constraints
Size of other mobile supply water apparatus.
According to NFPA 1901 the apparatus (mobile water supply) must carry at least ($$$$$) to be considered a mobile supply apparatus.
1000 gallons
Mobile supply apparatus
The weight distribution and load requirements generally limit tank capacity to ($$$$$) or less for single rear agile vehicles.
1500 gallons
When tank capacities of greater than ($$$$$) are desired tandem rear axles, tri axles, or tractor trailer design should be considered.
1500 gallons
($$$$$). In this mode, the apparatus is parked at or near the fire scene and pumpers take water directly from the tank of mobile supply apparatus.
Nurse tender
($$$$). In these operations, mobile water supply apparatus dump loads in to a portable water tank or nurse tender and then go to a fill site and reload.
Water shuttle operation
