Fire Apparatus Driver/Operator Chapter 11

Study Notes

First task: Assess the situation and determine the best strategy for fighting the fire.
Lay starting at the fire: The forward lay starts at the fire and connects to the hydrant.
Transferring water from internal tank to external source: This process is called tanker shuttle and involves connecting the fire apparatus to a water source and using pumps to transfer water from the tank to the hose lines.
First arriving engine's lay: The most common lay for the first arriving engine at a fire is the forward lay.
5 on transmission selector: This indicates that the transmission is in fifth gear, used for cruising speed.
Recommended speed after hydrant stop: The engine should proceed at a slow, safe speed while ensuring safety for everyone involved.
Split lay: This lay is performed when multiple fire apparatus are responding to the same fire scene, allowing each engine to connect to a different part of the fire.
Damaged exterior FDC: If damaged, use a portable pump and hoses to supply water to the fire.
Goal at the beginning of the changeover process: To maintain a continuous flow of water to the fire.
High idle switch: Helps ensure the alternator produces enough charge for the electrical system.

Inverter: Converts DC (direct current) to AC (alternating current) to power electronic devices.
Load Sequencer: Manages the order in which appliances are powered on in an automatic load management system.
Load Monitor: Monitors the electrical load of the fire apparatus.
Load Shedding: Automatically reduces the electrical load to prevent overloading the system.
Power source: The most common power source for fire apparatus is a 12-volt battery system.
Actuator: A mechanical device used to control the movement of a tool, such as a hydraulic rescue tool.
Electrical cord size: The most common size for 110-volt powered equipment is 12 gauge.
