How are engine and truck units differentiated in dispatch?

• A. Engine units typically provide water and suppression; truck units provide access, ventilation, and ladders
• B. Engine units carry ladders; truck units pump water
• C. Engine units do nothing; truck units do all fire suppression
• D. Engine units are only for medical transport

Answer: (A)

Engine units are built to get water to the fire and apply it for suppression. They bring the pump, water supply, hoses, and nozzles, with the primary role of extinguishing and controlling the blaze while protecting occupants and crews.

Truck units focus on getting to and working around the structure to support suppression. They carry ladders, ventilation tools, forcible entry equipment, and lighting, and their tasks include gaining access, creating ventilation to remove heat and smoke, performing searches, and supporting rescue operations.

This matches the idea that engine units provide water and suppression, while truck units provide access, ventilation, and ladders. The other notions—engines carrying ladders and trucks pumping water, engines doing nothing, or engines only handling medical transport—don’t align with how these roles are defined on the fireground.
