Ch 13. Water Shuttle Operations

Question 1

What is the primary purpose of relay pumping operations or tanker shuttle operations?

Answer 1

Relay pumping or tanker shuttle operations are the primary methods of providing water supply to points remote from a water source

Question 2

What are some of the pros and cons of relay pumping?

Answer 2

Relay pumping usually provides a more reliable source of continuous water with the use of your apparatus, but it is more labor-intensive to take up when the incident is terminated

Question 3

What is a safety concern of shuttle operations?

Answer 3

Shadow operations rely on the constant movement of apparatus at the fill in dumpsites as well as on the route between and two locations. This increases the chance of collisions.

Per NFPA 1901 Water tenders are required to be capable of dumping water from which sides?

Answer 18

From the left, right, and the rear of the apparatus

Question 19

What two types of large tank discharges are in use on water tenders?

Answer 19

Gravity and jet assisted dumps

Question 20

Where might the valve mechanism for a gravity dump valve be assigned for manual operation?

Answer 20

Discharge location on the sides or rear of the apparatus

Question 21

Some fire departments have chosen to install larger gravity dumps underwater tenders instead of jet assisted dumps to:

Answer 21

Limit costs and address the operational issues concerning jet assisted dumps

Question 22

When setting up a water shuttle, what is a very important part to the success of the shuttle operation?

Answer 22

It’s important to have the number of vehicles necessary to maintain a constant supply of water at the scene. 

Question 23

What is a safety issue concerning water shuttles a narrow roads?

Answer 23

Vehicle tires may leave the road, creating potential for rollover

Question 24

What affects might water shuttles face from steep grades?

Answer 24

It increases wear on apparatus

Question 25

When establishing Water shuttle operation integrated into the incident command structure, it is recommended that the incident commander make designations that adhere to what command structure?

Answer 25

NIMS

Question 26

Who is often responsible for water supply operations as assigned by the water supply group supervisor?

Answer 26

Company officers and or driver/operators

Question 27

When operating from any hydrant during fill operations, Which discharges on the hydrant should be used?

Answer 27

All available hydrant discharges

Question 28

In order to maximize the flow available while supplying a tender during drafting operations, the driver/operator should seek a position that requires a __________of lift. 

Answer 28

Minimum of lift

At the fill site, the water tender position should accommodate empty water tenders that need to line up and wait their turn to be filled, but if this arrangement becomes too congested preparation’s can be made to establish what?

Answer 31

Establish another water supply fill site

Question 32
