Because water is better to use to put out fires than sand.
firefighters use water because when water touches something it cools down
firefighters use carbon dioxide to put out fires.
Firefighters use water, predominantly, to fight forest fires. Sometimes they can sprinkle a compound to reduce the spread of flames, but water is the typical method.
you could,but it'd be better to use sand

water is the most practical thing to use
It's used to extinguish fires because carbon dioxide supersedes the oxygen. Without oxygen, no fire can burn.
You can use a pan lid to put out a fire. If it's a grease fire, you can use lots of baking soda to cover it. However, the best item to complete the job would be a fire extinguisher available at a home store such as Lowe's or Home Depot.
Firefighters use several kinds of fire-fighting chemicals: For ordinary fires: water or a Class A extinguisher For fires involving combustible chemicals such as gasoline, grease, or oil (Class B): C02 (carbon dioxide), dry chemical extinguishers such as foam, sodium bicarbonate, potassium bicarbonate, or monoammonium phosphate For fires involving electrical equipment (Class C): C02 or dry chemical extinguishers such as the above -- never use water on an electrical fire!

there is a specle fire extinguisher that is for elecrical fires ... DONT USE WATER
There are many different ways that science is involved in firefighting. The most obvious one is that you can put out fires with water, and yes, that is chemestry. Firefighters also use science to put out forest fires. They start a new fire in a certain location with a drip tourch, and that will meet the forest fire and burn it out. Science is involved in just about everything, even firefighting. you can take fire science classes at most collages and unniversities
