10. Ladder Company 1, arriving for a fire at a lower Manhattan construction site, discovered the fire involves the wooden forms used for the shoring and forming of recently poured concrete. As they climb the stairs to the fire floor, a student studying for the next lieutenant’s test made the following statements. His officer should correct which one? (SB 66)
a. The fire load in this type of building is created by the storage of sheets of plywood and wood studs stripped from a cured floor. This lumber is usually found on the floor below the most recently poured floor
b. Problems with structural failure will not usually occur on the temporary storage floor. The problem would be a fast moving fire, with large open vertical and horizontal areas
c. The structural stability of the floor below the most recently poured floor should be considered sound
d. If units observe studs placed approximately eight feet apart as they proceed upward in the building, it can be assumed these floors are in the advanced stages of curing and should not be a problem if exposed to fire
This lumber is usually found stored on the floor which is two levels below the most recently poured floor and will serve as the forms for the next floor to be poured.
11. A Chief Officer is trying to decide whether to institute an interior attack in a building under construction where recently poured concrete and its associated wood forms are being utilized. There is no supervisor or foreman present. The chief should assume that the concrete was poured with how many hours of her unit’s arrival? (SB 66)
Obtaining this information is often difficult, and if available, not always accurate. Unless there is a
responsible person on the job site, such as a construction engineer, building superintendent or concrete foreman and he states exactly the time that the concrete was poured, arriving units should assume that it was sometime within the prior 24 hours.
12. A good officer uses critiques as a valuable tool for training and relearning. You are an engine company office about to critique a particularly difficult 10-75 at which your unit operated first due. You would be correct to remember all but which of the following? (SB 70)
a. The critique should take place at the scene or in quarters
b. The senior firefighter on duty should lead the discussion
c. All criticism should be constructive. No one should suffer unnecessary embarrassment
d. The fire or emergency is not over until all members of the unit have learned all that can be learned from the incident
The company officer should lead the discussion, i.e., the critique. He/she might begin by stating what he/she saw, thought and did. Then the firefighters should state their own observations and actions. Remember: all criticism should be constructive, because critiques are intended to be training exercises. Although mistakes should be discussed, the company officer must be particularly careful that no one suffers unnecessary embarrassment.
1. A senior firefighter supervising a proby made the following statements while the proby was recharging the unit’s 2 ½ gallon AFFF extinguisher. The proby realized that the senior firefighter was not entirely correct in which statement? (Add. 2, sec 2.2, 2.5, 4, 5)
