How does heat move from a fire to a fire sprinkler?
Standard wet-pipe fire extinguishers (the kind that you'll find in most buildings) have 2 components: the fire pump and the pipe system. Within the pipes there is pressurized water, held in place by the sprinkler heads. This water is supplied to the pipes by the fire pump.If you look carefully at a fire sprinkler head, you'll notice what appear to be glass bulbs filled with a colored liquid. The liquid in these bulbs is extremely heat sensitive, and the heat from a fire in the building will cause it to expand and burst the bulb. This releases the pressurized water from the pipes into the room with the fire. Another type of sprinkler valve uses a "fusible link" that is calibrated to melt and open the valve when it is hot enough.The release of water by the sprinkler head causes a drop of water pressure in the fire sprinkler system, which sends a signal to the fire pump that it needs to kick on and supply more water pressure to the sprinklers so they can continue to put out the fire. Once the fire is extinguished, the only way to turn the sprinklers off is to shut them off at the pump. This is usually only done with permission of the fire department.Some fire sprinklers work by turning on the whole system at the signal of smoke or fire and dousing the entire area with water.Fire sprinklers are often found in public buildings. They are connected to smoke detectors, so when the detectors go off, the fire sprinklers do as well.Standard wet-pipe fire extinguishers (the kind that you'll find in most buildings) have 2 components: the fire pump and the pipe system.

What is used to put out gasoline fire and why?
Most likely an extinguisher that uses sand or foam to choke the oxygen out of the flame because this type of fire is hard to put out with water or other means.
What you do in the event of an electrical fire?
An electrical fire is a class B fire. If possible, the electricity causing the fire should be shut off. The most common fire extinguisher for this type of fire is an ABC dry chemical extinguisher. Class C can be used in a pinch, but a class A should NEVER be used if the electricity is still present in the fire.
Why does spraying water on fire take it out?
The fire triangle is fuel (something that will burn), oxygen and heat. If you take away any of the three the fire will go out. Water reduces the temperature and causes the fire to die out. A note here: Water is used on class "A" fires only. A class "A" fire is anything that will leave an ash when burned such as paper, wood or cloth. If you were to try to use water on a class "B" fire (a liquid fuel fire) the water will cause the liquid to spread out rather than cool it and make the fire worse. A class"C" fire is anything electrical and while water may put the fire out you run the risk of electrocution if you use water. There is also a class "D" type of fire that includes metals such as magnesium that will burn. If you put water on burning magnesium such as an airplane wheel the magnesium may explode.

Combustible metals like aluminum or magnesium
What type of extinguisher should be used on an electrical fire?
A water-type or water-based foam type of extinguisher should not be used on an electrical fire because water and foam are electrical conductors and could result in electrocution of the person using the extinguisher or anyone stepping in the water.

What does the b indicate on a b1 fire extinguisher?
The B determines the type of fire that can be extinguished, and in this case it would be flammable liquids such as gasoline, grease, oil, diesel fuel, and kerosene. The number indicates the approximate number of square feet the unit can extinguish, so a B-1 would be a relatively small extinguisher.
How much water does a wet pipe fire sprinkler spray per minute?
25-150 gallons per minute is standard depending on the type of sprinkler head. Residential sprinklers will be closer to 25. That flow is for a SINGLE sprinkler head. Typically the fire will be extinguished by just activating one sprinkler head.
