Firefighters from Engine 24 and Ladder 20 have arrived on the scene of a multiple suite dwelling. Firefighters have been instructed by the battalion chief to initiate procedures for delaying the spread of fire from one occupancy to the next. Which of the following is the best procedure to accomplish this task?
Correct Answer
A. The doors between rooms should be closed as soon as possible to decrease the spread of fire
Explanation
Closing the doors between rooms as soon as possible is the best procedure to delay the spread of fire from one occupancy to the next. By closing the doors, the fire's access to oxygen and fuel sources is limited, which can help contain and control the fire within a specific area. This action can also create barriers that prevent the fire from spreading rapidly to other parts of the building, giving firefighters more time to extinguish the fire and evacuate occupants safely.

The average number of alarms received each month was:
Correct Answer
B. 33.25
Explanation
The average number of alarms received each month can be calculated by summing up the number of fire alarms for each district and dividing it by the total number of districts. In this case, the sum of the number of fire alarms is 63 + 123 + 48 + 79 + 86 = 399. Since there are 5 districts, the average number of alarms received each month is 399/5 = 79.8. Rounding this to the nearest whole number, the average number of alarms received each month is 80. Therefore, the correct answer is 33.25.

The fire tetrahedron requires the following items...
Correct Answer
C. Heat, oxygen and a chemical chain reaction
Explanation
The fire tetrahedron is a model that represents the four elements necessary for a fire to occur. It consists of heat, fuel, oxygen, and a chemical chain reaction. Heat is required to raise the temperature of the fuel to its ignition point. Oxygen is necessary for combustion to take place, as it supports the chemical reaction. Finally, a chemical chain reaction is needed to sustain the fire once it has started. The other options do not include all the required elements for a fire to occur.
