Answer 14

14. C

Question 15

15. In order to prevent slippage of the butt, or movement of the top of a raised portable ladder, it is important that it be butted by a member. In which of the following cases is this act of safety a requirement?
    a) Fire
    b) Emergency
    c) Rescue
    d) Drill
    e) All of the above

Answer 15

15. E

Question 16

True or False
16. In order to correctly butt a portable ladder, the member places his/her right foot in the center of the bottom rung, maintains a downward pressure, and positions his/her left foot behind them at a comfortable distance to maintain balance and provide resistance against ladder movement.

Answer 16

16. F

Question 17

True or False
17. When butting the ladder it is important for the butt firefighter to grasp the rungs shoulder height and not the ladder beams.

Answer 17

17. F

Question 18

True or False
18. If a member is working off one side of the ladder, the butt firefighter moves his/her foot from the center of the bottom rung of the ladder to the side opposite the one from which the member is working, and places their foot next to the beam. This will prevent the bottom of the beam from shifting due to the relocated weight of the member working on the ladder.

Answer 18

18. T

Question 19

True or False
19. The aluminum portable ladder, if it is to be left unattended, should be secured at the tip by the last member that climbs the ladder. This is to prevent the ladder from being dislodged from its position by the wind or by the impact of water from a hose line or a large caliber stream.

Answer 19

19. F

Question 20

True or False
20. The butt firefighter must be aware of the force that causes the outward slippage of the butt of the ladder. This force is in direct proportion to the climbing member’s weight, decreases as firefighter ascends the ladder, and is minimum at the top of the ladder. Because of this, extra care must be exercised when a member receives a victim at the top of the ladder.

Answer 20

20. F

    onto the side of the beam

Answer 21

21. B

Question 22

22. Which of the following is an incorrect procedure during freezing weather when ice forms on the ladder due to water spray?
    a) Position the rung of the ladder under the arch of the boot, next to the heel.
    b) Position the feet on the rungs directly next to the beams with each step, to
    avoid slipping
    c) The hands remain on the top side of the beams
    d) Should a member slip while climbing, they should immediately pull themself
    into the ladder and regain their footing.

Answer 22

22. C

Question 23

23. There are some duties that require the use of the Leg Lock or the Life Safety Belt for safety. How many of the following are correct regarding these procedures?

    b) If a member wants to lean to the right and vent a window, they will lock their left leg on the ladder.
    c) To perform the Leg Lock, the locking leg is placed over and under the rung that is one rung above the one in which the member is standing.
    d) The instep of the locking leg is placed on the beam of the ladder opposite the member’s working side.
    e) The arch of the foot on the rung is placed against the other beam.
