Engine Ops | Hose Line Deployment 2

What is the reason for not being able to manipulate the larger handlines in the same manner as the smaller ones?

The larger handlines are designed to be used with a different nozzle technique
The potential fire in a commercial environment requires a different approach
The larger handlines are less maneuverable in a commercial environment
The commercial environment does not afford the same luxuries as other environments (correct)

Why should water be flowed early in a commercial environment?

To take advantage of the larger handline's inherent strengths (correct)
To prevent potential fire hazards
To counteract the compartmentalization of the environment
To manipulate the larger handlines more effectively

What is the recommended goal when operating in a commercial environment?

To achieve 90° left, right, and up from center with the nozzle
To win back the structure five feet at a time (correct)
To flow 160 GPM of water
To manipulate the larger handlines methodically
