Study Notes

Fire Department Pumpers

Minimum pump capacity for fire department pumpers is 750 GPM as specified by NFPA 1901.
Foam tank capacity on municipal pumpers typically ranges from 20 to 1,000 gallons.

Mobile Water Supply Apparatus

Primary function in a 'mobile shuttle operation' is to transport water to refill tanker trucks for firefighting efforts.
Considerations for mobile water supply apparatus include tank size, pump capacity, and ability to refill quickly.

Purpose and Functionality

Main purpose of a fire department pumper is to supply water for firefighting operations through pumping and hose deployment.
Mini- or midi-pumpers are primarily known for their compact size and maneuverability for urban and wildland firefighting.

Quint Requirements

Minimum pump capacity required for quints, according to NFPA 1901, is 1,000 GPM.

ARFF Apparatus

Primary function of an Aircraft Rescue and Firefighting (ARFF) apparatus is to respond to aircraft emergencies and fires.

Power Systems and Generators

In vehicles, a step-up transformer called an inverter is used to convert DC power to AC power for various electrical systems.
Most common power sources for vehicle-mounted generators include the vehicle’s battery and engine.

Wildland Apparatus Specifications

Typical pump capacity for wildland apparatus ranges from 100 to 500 GPM, with tank sizes generally between 150 to 600 gallons.
Wildland apparatus are often mounted on chassis designed for off-road conditions to enhance mobility in rugged terrains.
In a pump and roll system, the pump is powered by the vehicle's engine while in motion, allowing continuous fire suppression.

Maintenance and Inspections

Primary purpose of preventative maintenance programs is to ensure the reliability and longevity of firefighting apparatus.
During the first 6 months after an apparatus is received, a thorough inspection and any necessary touch-ups to paint and protective coating should be done to prevent corrosion.
Towels that are typically not acceptable for cleaning automotive glass include ones that leave lint, such as terrycloth materials.
A walk-around inspection should be performed in a zigzag pattern to ensure thorough coverage.

Tire and Brake Maintenance

According to NFPA 1911, all tires should be replaced every 5 years regardless of their condition.
Purpose of a load sequencer in an apparatus is to manage the power distribution of electrical systems for efficient operation.
Tire selection for fire apparatus is determined by factors like the weight of the apparatus, terrain, and expected operational conditions.
A load monitor in an apparatus provides information on electrical load to ensure the system operates within safe parameters.

Weight and Steering Mechanics

Curb weight is defined as the weight of a vehicle with all fluids and a full tank of gas, but without any passengers or cargo.
Maximum steering wheel play on a 20-inch steering wheel should not exceed 2 inches.

Brake Systems

Purpose of the air pressure protection valve in apparatus with air brakes is to prevent brake failure if air pressure drops too low.
ABS (Anti-lock Brake System) in an apparatus prevents wheel locking during hard braking, improving control.
Apparatus brakes should be thoroughly tested as per NFPA 1911 recommendations every 12 months.

Emission Controls and Vehicle Maintenance

Diesel particulate filters reduce emissions from diesel engines, capturing soot and particulate matter.
Most vehicle checks, excluding transmission fluid, should be performed every 3,000 miles or after a specific time interval, such as 6 months.
Important considerations before jump-starting a vehicle include ensuring correct polarity and avoiding potential short circuits.
A pump and piping should be thoroughly flushed before an apparatus is placed back in service to remove any contaminants and ensure operational readiness.
