1

Atmospheric pressure which is pressure created by the weight of the atmosphere is ______ at sea level

14.7 psi

2

As you move up in elevation from sea level and the atmosphere thins or lessens, this supply pressure decreases : the pressure drops approximately ____ for every 1000 ft of elevation above sea level

0.5 psi

3

The atmospheric pressure at your drafting site is the maximum supply pressure for

Drafting

4

Is any pressure less than atmospheric pressure

Vacuum

5

A fire pumper in good condition should be able to develop a vacuum equal to about ______

22 inches

6

Is the height that a column of water can be lifted in a quantity considered sufficient to provide reliable fire flow

Dependable lift

7

It is generally considered to be 15 ft

Dependable lift

8

Is the process of removing air from a fire pump and replacing it with water

Priming

9

A ____ is a positive displacement pump used to remove the air from the pump during priming

Priming pump

10

The ____ is a small tank that holds the lubricant for the priming pump

Primer oil reservoir

11

It is generally located slightly higher than the pump and often enclosed behind an access panel on the side or the top of a fire apparatus

Primer oil reservoir

12

The best way to assess the operational readiness of the priming system is to conduct a ____ periodically

Vacuum test

13

A fire pump that retains any vacuum for ____ should prime and draft water easily in most situations

5 minutes

14

Is a vital part of any fire incident and can become a major part of the incident management system in scenarios where a reliable public water or private water system is not available

Water supply management

15

Position reports to the operations section chief and is responsible for ensuring that an adequate supply of water is available to mitigate the incident

Water supply officer

16

When drafting water is the chosen method for providing that supply, the ____ of the static water source becomes a primary consideration in the process of selecting an appropriate drafting site

Reliability

17

The first consideration in determining the reliability of a static water source is to estimate the _____ of water available

Quantity

18

Calculating available water in a non moving source

Q= LxWxDxC

19

Calculating available water in a moving source

Q= WxDxVxC

20

The next step in determining the reliability of a static water source is to consider the ______ of the water in the static source

Quality

21

Never walk on ice without a personal flotation device and safety line unless you know for certain the water is less than

Waist deep

22

Clearly it is a good idea to identify drafting sites during _____ efforts rather than waiting for a fire to force you to find one in an emergency situation

Preplanning

23

The installation of ____ should be considered in areas where access is difficult or when a location would make an ideal drafting site that could be used frequently

Dry hydrants

24

Dry hydrants can be required, in local fire prevention codes to be installed by the property owner to provide quick access to _____

Static water supplies

25

Consider placing _____ near static water sources whenever accessing these sources with a fire pumper is not possible

Portable pumps

26

May be used when the water is not deep enough to allow the use of conventional hard sided drafting supply lines

Floating pumps

27

Another option for drafting from relatively shallow flowing water sources is to place a ___ in a stream bed

Dam

28

Whenever you have multiple, strong options for possible drafting sites, the best choice, is determined by the _____

Location and the purpose of the drafting operation

29

The next step in the process of obtaining a water supply from a static water source is establishing a pumping operation from a

Draft

30

The first step in establishing a drafting operation is to locate an _____

Appropriate water source
