AVP Purpose

- Bleed air from charged hoseline - Assess fire stream when flowing - Check fire stream for appropriate pattern

Evolution Decision factors:

- Location of Fire - Severity of Fire - Type of Construction

Team integrity in IDLH via:

- Physical Contact - Audible Comms - Visual Contact

Break 200 feet of 2 and 1/2 inch into two sections and hand female couplings off to #4 at tri-gate. Stretch male couplings 50 feet beyond monitor. 3. Turn around and walk back, past the monitor about 20 feet. Turn again and connect each to the monitor, and spread the hoselines into position. 4. Secure anchor chain to the hoselines where they cross in front of the monitor. Tie a body loop around the lines where they cross behind the monitor. - Position #4 Firefighter: - Irons to the fire side, and remove 2½” hose from bulk bed.
