24: B.
If you suddenly stop near or close to the nozzle, hydrant or valve quickly, suddenly the water stops running toward them. This may be literally thousands of meters of water. When the valve is kept closed, everything is possible, and tries to develop. What's driving force on the valve and pipes and all. Very, very bad. We close our mouths too quickly even for the training, and broke a 200-foot home on the road.
9:
Fire hose wrong with sunlight. Therefore, all the beds of the pipe must be covered.
25:
Consider this: If you are on fire with a jet of water, all that fire is delayed. If I push it to the burned area of the structure, which is distributed. When you start your attack from the unburned side and push it on the burned area, there is no possibility of the spread, leading to a decline much faster.
26: B or C. I do not know exactly what they ask for the answer.
The answer is D, because it steh for themselves.
The first thing you do when you have a room on fire, is a direct flow on the roof cool the atmosphere and the possibility of reducing to a flashover.
27: D
The reaction of the nozzle is less change with ground fog, but do not forget the nozzle, a jet of water directly before entering a building. If the nozzle is opened in the fog, the entire steam room and you and your partner like a lobster is cooked. For this reason, our business, always in a straight stream nozzles.
This is for your own safety, not the work alone. If you do not know does not explain the answer, ask your teacher. The simple answer to this question will not make a good fireman, and you will do later when you reach a situation where you need these skills.
Good luck.
