What portable equipment must pumpers carry per NFPA?
Ground ladders, SCBA, forcible entry tools, salvage tools, water tank, EMS equipment.
What is a rescue pumper?
Combines pumper with rescue functions, with more compartment space and extrication equipment.
What are Class A and Class B foams used for?
Class A for ordinary combustibles, Class B for flammable and combustible liquids or gases.
What are the types of foam proportioning systems on foam pumpers?
Around the pump, direct injection, balanced pressure foam proportioning system, compressed air foam systems (CAFS).
What is a characteristic of balanced pressure foam proportioning systems?
Reliability of foam at large flows.

What feature do foam pumpers often have for large flows?
Large turret capable of flowing the pump’s capacity.
What is a common Class A foam system on municipal pumpers?
Compressed Air Foam System (CAFS), available on some discharges.
How do municipal foam proportioning systems compare to industrial ones?
They are scaled-down versions of industrial fire pumper foam systems.
What is the typical foam tank size for municipal foam pumpers?
20-100 gallons, fillable with 5-gallon buckets.
What defines an initial attack apparatus?
Smaller apparatus like mini or midi pumpers designed for rapid response.
