Question 5: A manual states: 'Ground ladders should be placed at a climbing angle of 75 degrees from horizontal. An easy method to verify this angle is to stand at the base of the ladder with arms extended forward — your palms should reach the rung at shoulder height.' According to the manual, at what angle should ground ladders be placed?
- 60 degrees from horizontal
- 70 degrees from horizontal
- 75 degrees from horizontal (Correct answer)
- 80 degrees from horizontal
Correct answer: 75 degrees from horizontal
The manual specifies ground ladders should be placed at exactly 75 degrees from horizontal.
Question 6: A passage reads: 'A flashover occurs when all combustible materials in a compartment reach their ignition temperature simultaneously, resulting in a sudden total involvement of the space. Warning signs include rollover, heat buildup near the ceiling, and rapidly darkening smoke.' Which of the following is listed as a warning sign of flashover?
- Blue flames appearing near floor level
- Smoke becoming lighter in color
- Heat buildup near the ceiling (Correct answer)
- Sudden drop in room temperature
Correct answer: Heat buildup near the ceiling
The passage lists heat buildup near the ceiling as one of the three warning signs of flashover.
Question 7: A directive states: 'Incident Command must be established within the first three minutes of arrival at any multi-unit response. The first arriving unit assumes command and retains it until formally transferred to a senior officer.' Who assumes command first according to this directive?
