3. self-awareness;
4. strong knowledge of the SCBA;
5. psychological control, or one’s own ability to control their breathing rate

Question 2

What pressure does the low pressure reducer bring the psi down to from the cylinder?

Answer 2

The back frame mounted pressure reducer assembly reduces the air pressure from the cylinder pressure down to 110-160 PSI

Question 3

The RIC UAC stands for..

Answer 3

Universal Air Connection

Question 4

the UAC is located where?

Answer 4

Universal Air Connection (UAC) is located on the left side of the pressure reducer assembly

Question 5

What is kickback on a chainsaw?

Answer 5

This condition occurs when the upper quadrant of the bar nose contacts a solid object or is pinched

Question 6

How many packets of AMSOIL oil should be used per gallon of gasoline, and what ratio does this yield?

Question 8

what are the two sizes of smoke ejectors used by MFMD?

Answer 8

There are two sizes of gasoline powered smoke ejectors - 18 inch and 21 inch.

Question 9

The 18” smoke ejector moves how much air?

Answer 9

14,800 CFM

Question 10

the 21” smoke ejector moves how much air?

Answer 10

21,150 CFM

Question 11

What is the procedure for stopping the smoke ejector when it will not be used for a long time?

Answer 11

Long Stops: When the engine is not going to be used for a while, turn the fuel cock to OFF and let the engine run until the fuel in the carburetor gives out stopping the engine.

Question 12

What is the maximum pressure Holmatro tools operate at?

Answer 12

10,500 PSI

Question 13

Holmatro tools are stored in what position?

Answer 13

All tools will be stored in a slightly opened position (1/4”) to relieve pressure on internal parts.

Question 14

What is the proper air pressure the Ajax tool should be operated at?

Answer 14

The proper pressures to operate the tool is 90 PSI for normal auto body metal. Heavier metals such as door locks, nader pins, door hinges, etc. require higher pressures 150 to160 PSI. Maximum pressure should never exceed 300 psi.

Answer 15

300 degrees F

Question 16

how far apart should FFs space themselves when climbing ladders

Answer 16

at least 10’ apart to balance load

Question 17

Hose straps should be used how often when working with a charged line?

Answer 17

Hose straps should be used every 10’ with one at the top of the ladder, or use a leg lock.

Question 18

what is the maximum amount of weight air bags should be used to lift?

Answer 18

146,000 lbs is the maximum weight

Question 19

what air pressure is used to inflate the air bags?

Answer 19

118psi is used to inflate the bags.

Question 20

how often should air bags be replaced?

Answer 20

Air bags should be replaced every 10 years.

Question 21

Rafters and joists are typically what size or larger on conventional construction?

Answer 21

2 x 6 or larger, with decking usually 1 x 6 set perpendicular or diagonal to rafters

Question 22

conventional construction is found in what era, typically?

Answer 22

Pre-1960’s, less often as buildings grow newer

Question 23

When on the roof and determining the feasibility of vertically ventilating a structure, the roof team communicates with _______________ for updates.

Answer 23

Communication should be with INTERIOR, not command, for fire updates.

Question 24

The effective height of a building is determined how?

Answer 24

The effective height is calculated from the butt of the ladder to the eave line or top of the parapet.

Question 25

Five safety considerations considered as absolutes when ventilating over a fire are:

Answer 25

1. Always ladder the strong areas of the building away from potential structural problems such as windows, large doors, etc.
2. Always have two means of escape from the roof. If your only means of escape is by ladder, make sure 2 ladders are placed.
3. Ladder the building and approach the fire involved area from the uninvolved area.
4. A minimum of two firefighters should be assigned to ventilate. No single-person attempts to ventilate.
5. While ventilating, work from the weak area toward the strong area.

Question 26

The rule of thumb when cutting a ventilation hole, regarding size is?

Answer 26

The rule-of-thumb size for this hole is approximately 10% of the area of the involved room or rooms

Question 27

the best placement for a fan for PPV is?

Answer 27

6 feet back from the door and tilted 20-30 degrees upward, which will create a proper “seal” over the .

Question 28
