Title: Aerial Master Stream Operations Rev. Date: 07/2019
Standard Number: 7 Time Standard:
STANDARD:
Given a crew of 3 on 9953, the crew will establish a water supply use the aerial master stream for
defensive firefighting operations. The evolution begins when the Firefighter steps off the truck
to establish the water supply. Time ends when water is flowing from the aerial master stream.
PERSONNEL IDENTIFICATION (by seating arrangement):
Captain
Engineer
Firefighter
PROCEDURE:
1. Truck stops at designated hydrant and Firefighter removes equipment necessary to
establish a 4” wet feeder.
2. As soon as the required equipment is removed and the 4” feeder is wrapped around the
hydrant, the Firefighter will make eye contact with the Engineer and yell, “Lay Away.”
Firefighter flushes the hydrant, then connects 4” feeder to the hydrant.
3. Captain and Engineer spot the truck for access to reach the objective, outside of any
potential collapse zones. The truck will be placed in such a way that the ladder will be
in its strongest configuration given the scenario (close to the objective, ladder at the
shortest extension and steepest elevation to achieve the evolution.)
4. Engineer sets the parking brake and engages the PTO prior to leaving the cab, then
chocks left front wheel.
5. Engineer proceeds to the rear of the truck, breaks the feeder line at the appropriate
coupling and connects the 4” feeder to the intake.
6. Engineer will signal the Firefighter to charge the line via radio, two short air horn blasts,
or by line of sight. Firefighter charges the feeder line, ensuring the hydrant is
completely open and proceeds to the truck, removing any kinks in the feeder line.
7. Captain sets stabilizer plates.
8. Engineer sets and pins stabilizers.
9. Captain and Firefighter don ladder belts, SCBA’s, and obtain radios, TIC, tools needed
for the evolution (if they are to be in the platform for firefighting operations.)
10. If Captain and Firefighter are to be in the platform for firefighting operations, Captain
operates the aerial to place it in the desired location. If not, Engineer operates aerial.
11. Engineer places the midship pump into “pump.”
12. Engineer adjusts pump pressure accounting for aerial height and GPM required.
Note: Per Cal/OSHA 29CFR1910: “2 in 2 out” must be established prior to any interior fire ground operations
whenever there is a possibility that an IDLH (Immediately Dangerous to Life and Health) atmosphere exists.
