Chapter 13

Question 1

The most favorable aspect of a water shuttle operation is?

Answer 1

The ease with which it is terminated when the incident is concluded

Question 2

Per nfpa 1901 water tenders must be designed to be filled at a rate of at least what gpm?

Answer 2

At least 1000 gpm, pumpers at the fill site must be rated at that capacity or greater

Question 3

Vehicle weight restrictions generally limit single rear axle apparatus to a maximum of what capacity?

Answer 3

2000 gallons

Question 4

There is no need for a separate pumper at the fill site if?

Answer 4

You are using a vacuum tender, they are able to self-fill from a static water source at a rate of up to 2000 gpm with a lift of up to 22ft. They are also capable of discharging water at a rate of up to 1750 gpm

Question 5

Faster water shuttle operations are achieved by?

Answer 5

Efficient filling and dumping operations, not speeding

Question 6

Apparatus using medium diameter supply hose for filling should have at least how many external fill connections?

Answer 6

At least 2 external fill connections piped directly into the tank. If ldh is used one is generally sufficient

Question 7

Legit might using ldh for filling provide little advantage?

Answer 7

Ldh remains particularly filled with water during each subsequent fill operation. The hose is extremely heavy and may be difficult to handle. Any advantage gained by faster fill time may be lost in longer handling times.

Question 8

Nfpa 1901 requires water be capable of being dumped from?

Answer 8

Left right and rear of the apparatus

Question 9

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

Answer 9

Gravity and jet assisted dumps

Question 10

Driver operator must be sure that the vents are completely open during what operations?

Answer 10

During fill and dump operations

Question 11

The dump site should be located where?

Answer 11

Relatively close proximity to the incident scene, but not so close where it would hamper operations or be in danger of exposure to fire or collapse

Question 12

Fill and dump sites should be pre planned to what kind of locations?

Answer 12

Locations that allow for continual forward movement whenever possible

Question 13

Streets with Two way access are also referred to as?

Answer 13

Through streets

Question 14

What should be relayed in regards to tender location?

Answer 14

Must relay to the other when a tender has completed a portion of the relay and is headed in the opposite direction.

Question 15

When positioning to draft at a static water supply, you should seek a position that?

Answer 15

Requires a minimum lift in order to maximize the flow available to supply the tender. Position to a point of best advantage for the water source

Question 16

Regardless of the source what should be done by the full site pumper?

Answer 16

A booster line or other small discharge should be continuously flowed in the view of the driver operator

Question 17

When an exact fill spot has been determined what should be done?

Answer 17

Place a traffic cone or similar marker to denote the stopping point for the water tender driver operator. Position this cone so that it’s adjacent to the door of the driver operator.

Question 18

True or false? Using hose clamps on ldh may be unsafe. Flow through ldh should only be controlled at the pumper or with valve appliances

Answer 18

True

Question 19

What should not be done when filling apparatus from the top?

Answer 19

Do not fill with a portable fill device or an open hose butt due to the reaction of the hose line and possibility of firefighters sustaining serious injuries due to falls from the top of the tender

Question 20

What are firefighters at the fill site operating fill lines referred to as?

Answer 20

“Make and break” personnel in reference to their duties of establishing and removing connections between the water source and the tank

Question 21

What should the driver/operator do when they get to a fill site?

Answer 21

Remain in the apparatus can to ensure peak efficiency in apparatus movement, allowing the vehicle to be moved as soon as the fill is complete and the hose is removed.

Question 22

What are the three primary dumps site operational methods?

Answer 22

Direct pumping, nurse tender, portable water tank

Question 23

Water tenders do not need to be equipped with a fire pump as long as ?

Answer 23

They are designed with an adequately sized direct tank discharge valve (dump valve) and proper venting.

Question 24

What method is generally considered to the be the simplest and quickest method to ensure a constant water supply for fire attack operations?

Answer 24

Portable tank method

Question 25

What is the primary disadvantage of the portable water tank operations?

Answer 25

The substantial amount of working space required to operate the dump site

Question 26

Pumping through a discharge is less efficient than using a dump valve, as the flow is limited by the capacity of?

Answer 26

The tank to pump line, the pump capacity, and the ability to control the hose line at the point of delivery

Question 27

When pumping hose lines into portable tanks what must be done to the hose lines?

Answer 27

Hose lines discharging into the tanks must be secured. Ffs should not attempt to manually hold open the button of a hose line.

Question 28

Single portable tank operations are generally adequate for firefighting operations that require relatively low flow rates of?

Answer 28

Less than 300 gpm

Question 29

What is the type of portable tank that consist of a large bladder with a floating collar around the opening?

Answer 29

Self supporting or frameless water tank

Question 30

Any tank regardless of type must be?

Answer 30

Set up on a surface that is level as possible, and have a capacity at least 500 gallons larger than the water tank on the apparatus that will supply it

Question 31

Incidents that require a flow rate in excess of 300 gpm are best served by ?

Answer 31

Multiple portable tank operations

Question 32

What is the goal of multi tank operations?

Answer 32

To keep the tank from which the attack pumper is drafting full at all times

Question 33

What is an effective method of moving water from one tank to another?

Answer 33

Using jet siphons

Question 34

For operations that require more than three tanks and jet siphons and flows over 500 gpm what should be used to transfer water to the tank supply the attack pumper ?

Answer 34

Parallel jet siphons

Question 35

If conditions deteriorate at a dump site to a point where continued operation may be impractical and terminated, what should be done?

Answer 35

The new dump site must be determined and ready for operation and put into use with additional equipment before the original one is terminated.

Question 36

Most water tenders only dump what percent of their load before leaving the dump site?

Answer 36

Only 90 percent.

Question 37

What is the water shuttle flow rate formula?

Answer 37

Flow= 0.9 x TS / trip time
TS= tank size

Question 38

What is the travel time formula?

Answer 38

Travel time= 0.65 + (1.7) (distance)
Distance is measured in miles round trip

Question 39

What is the handling time formula?
