Introduction
• Varied nature of day-to-day calls
– No single apparatus is adequate for all calls.
– Specialized equipment is based on function
and capabilities.
• The driver/operator should know the
capabilities of each apparatus and what
each equipment brings to the emergency
scene.
2
Fire Apparatus Requirements
(1 of 2)
• Working with a manufacturer
– Many apparatus available
– Jurisdiction purchasing the apparatus must
convey the following specifications:
• Specific performance requirements
• Maximum number of fire fighters to ride on the
apparatus
• Specific electrical loads required
– Jurisdiction must conduct ongoing training.
2
Fire Apparatus Requirements
(2 of 2)
• Manufacturer must describe the
apparatus.
– Estimated weight, wheel base, turning radius,
principal dimensions, transmission, axle
ratios, and capacity of aerial platform
– Jurisdiction and manufacturer must work
together to construct the apparatus.
– NFPA 1901 defines all documents and
components.

Water on the Fire Apparatus
(1 of 4)
• Water is a major component of fire attack.
• To get water on the fire, water must be
pressurized by a fire pump.
– NFPA 1901 defines a fire pump as a water pump
mounted on an apparatus for firefighting.
– Fire pump must be capable of delivering a minimum
capacity of 250 GPM (1000 L/min) at 150 psi (1000
kPa) net pump pressure.
