Finding a heavy fire on the fifth floor of a six-story ordinary construction apartment house, the IC ordered the members of the second-arriving engine to assist the first engine in stretching their hoseline, even though it was clear that a second line would be required. The officer’s actions were:
A. Correct. Get the first line in operation quickly, before stretching additional lines.
B. Incorrect. The second line is needed and should be stretched immediately.
C. Incorrect. The members of the second engine should immediately begin evacuating the occupants.
D. Correct. Two companies are needed to operate a hoseline under heavy fire conditions.
A. Correct. Get the first line in operation quickly, before stretching additional lines.
Three strategic options in the firefighting plan include all but which choice? A. Attack the exposures. B. Make an offensive attack. C. Establish defensive position D, Take no action at all.
A. Attack the exposures,
What factors are primarily responsible for most fire spread to exposures? 1. radiation 2- conduction 3. convection 4. direct flame contact
C. 1 and 4 only
An officer in command of the first attack line finds that the line is unable to advance into the fire area due to heavy fire and tremendous heat. The officer should promptly request all but which of the following actions?
A. Call for additional ventilation opposite the line.
B. Call for an increase in pump pressure on the fast line.
C. Call for a backup line.
D. Call for an emergency evacuation of the building.
D. Call for an emergency evacuation of the building.
The hoseline referred to in question 13 is still unable to advance after trying all of the correct options cited above. What actions should you not consider next?
A. Change the direction of the attack
B. Use handlines to darken heavy fire.
C. Breach a wall to darken fire.
D. Use distributors, cellar pipes, high-expansion foam, etc.
B. Use handlines to darken heavy fire.
Officers in command of operations expect to see some visual indication that hoseline advance is successful. All of the following items should indicate that a line is successfully hitting fire EXCEPT:
- flames darkening down
- change in smoke color
- change in smoke volume
- change in smoke movement
- steam production
- cessation of collapse of a wood-frame home
