  230-250 psi

Question 11

Building Rescue choices

Answer 11

1) Interior stairs
2) Reliable exterior fire escapes
3) Ground ladders/ Aerial ladders

Question 12

Pierce Stick EPU operation times

Answer 12

• 7 min run time/ 30 min cool down

Question 13

Seagrave EPU operation times

Answer 13

• 5 min run time/ 25 min cool down

- do not run pressure over 2,000 psi

Question 14

Pierce bedding PSI

Answer 14

• 1800 psi to bedded

Question 15

Seagrave bedding PSI

Answer 15

• 0 or negative

Question 16

• Raising the aerial for victim rescue

Answer 16

• Perpendicular is the best ( reduces twisting/torsional stress)
• 70 to 80 degrees preferred (max loading)
  50 to 60 degrees is easier
• Raise ladder above victim then lower

200 lb victim jumping 3 ft = 700 lbs of force

Question 33

Stabilizers | STICKS

Answer 33

full load 100% - 0 to 3.5 side to side (slope) - 0 to 5.5 front to rear (grade) reduced capacity 50% - 3.6 to 5.5 side to side to side (slope) - 5.6 to 6.5 front to rear (grade) - when angles are greater that 5.5 slope or 6.5 grade do not operate the ladder

Tip control speeds

Answer 34

- operates 1/4 the speed that the turntable

Question 35

What is the greatest stability while ladder is set up

Answer 35

- operating the aerial on the longitudinal axis of the vehicle will offer the greatest stability. (ladder will be over the front or the rear of the cab) - operating the aerial perpendicular to vehicle creates less stability
