Evolution 4 Utilizing a modified Angus Foam Cannon or Akron Master Stream on a TL

Question 1

Connect a FIMM Pumper to a reliable water supply and charge pump. When a FIMM Pumper is connected to a hydrant or to a supply from the domestic water system, what must be utilized?

Answer 1

2.1

The 4½” back-flow prevention valve must be utilized.

Question 2

Tower Ladder members proceed to the Satellite and obtain the necessary equipment to attach the Modified Angus Foam Cannon or the Akron Master Stream Foam Nozzle to the Tower Ladder. The Tower Ladder should be raised and pointed away from the fire until foam operations are started. The bucket of the Tower Ladder should be unmanned.
The tools and fittings are to be used for both the Modified Angus Foam Cannon and the Akron Master Stream Foam Nozzle.
True or False

Answer 2

2.2 & 2.3
False
NOTE: The 500 GPM Akron Master Stream Nozzle screws onto the Stang without any special tools or fittings.

Question 3

While the Tower Ladder members are attaching the Cannon, the Satellite will stretch 5” hose to supply the manifold. Two 3½” hose lines will then be stretched from the manifold to the Tower Ladder. If the manifold is not placed into operation, then two 3½” hose lines will be stretched from what apparatus to the Tower Ladder?

Answer 3

2.4

The FIMM Pumper to the Tower Ladder.

Question 4

A Foam Carrier or Foam Tender will supply the Satellite Pumper with foam concentrate through 1¾” hose. In order to prevent back-up into the Foam Carrier, the pressure of this line should be __ PSI over the hydrant pressure.

Answer 4

2.5

50 psi

Question 5

When the foam supply is established, the Tower Ladder’s nozzle will be moved into position. The movement of the bucket will be done at the pedestal. It is necessary to supply the base of the Tower Ladder with at least 250 PSI in order to obtain the proper nozzle pressure. This usually cannot be accomplished without placing a _____ _______in the stretch located at the base of the Tower Ladder.

Answer 5

2.7 & 2.8

Relay Pumper

Question 6

Both the FIMM Pumper and the relay pumper need to operate in the what pump position?

Answer 6

2.9
Both the FIMM Pumper and the relay pumper need to operate in the volume position. The relay pumper operating in volume needs to have a supply pressure of 80 PSI to be able to supply the Tower Ladder with 250 PSI.

Question 7

In order to achieve the foam canon’s rated capacity of 1000 GPM, the FIMM pumper will have to proportion 30 GPM of concentrate into the water supply. A 1000-gallon booster tank will last about __minutes educting at an approximate 3% solution.

Answer 7

2.10

30

Question 8

What apparatus can be substituted for, and is preferred to a Foam Carrier?

Answer 8

2.11
The Foam Tender can be substituted for, and is preferred to a Foam Carrier. The Foam Tender has three 1000-gallons tanks that will last much longer than the 1000-gallon booster tank of the carriers. Also, other Foam Carriers can supply the Foam Tender if the need arises.

Question 9

The Satellite manifold or a pumper that is supplying another appliance should supply the Foam Cannon.
True or false

Answer 9

2.12
False
The Satellite manifold or a pumper that isn’t supplying any other appliance should supply the Foam Cannon. Approximately 1000 GPM of water is needed to supply the foam cannon.
