Final answer:
Probationary firefighters typically ride in the jump seat on the engine, which is located in the fire engine's cab. The jump seat allows them to observe and learn from more experienced firefighters.
Step-by-step explanation:
When you are a probationary firefighter, you will typically ride on the engine in the jump seat. The jump seat is a seat located on the fire engine's cab, usually behind the driver. It allows the probationary firefighter to be close to the action and observe and learn from the more experienced firefighters.
While sitting in the jump seat, the probationary firefighter may assist with tasks such as mapping out the fire hydrant locations, operating the radio, or helping to set up equipment at the scene of an incident. The jump seat also provides a good vantage point for learning about the various tools and equipment carried on the engine.
As the probationary firefighter gains experience and completes their training, they may move to a different position on the engine or be assigned to other apparatus like ladder trucks or rescue units.
