In theory, massive amounts of water will put out most fires. However, there are several kinds of fires where the use of water will either not work or will spread the fire or cause other hazards.
For example, using water on a magnesium metal fire could result in the water itself burning, creating a hydrogen and oxygen explosion.

What is AFFF made out of?
Aqueous film-forming foam (AFFF) is typically made from a mixture of fluorosurfactants, hydrocarbon surfactants, solvents, and water. These ingredients work together to create a foam that is effective at extinguishing flammable liquid fires by forming a blanket that suppresses the release of flammable vapors and cools the fuel surface.
What is the best type of fire extinguisher or fire agent that can be applied to all classes of fire?
red = water and is used for wood paper textiles and solid material fires. DO not use on liquid elictrical or metal fires. blue = powder and is used for liquid and electrical fires. DO not use on metal fires. yellow = foam and is used for liquid fires. DO not use on electrical or metal fires black = carbon dioxide (CO) and is used for liquid and electrical fires DO not use on metal fires. halon can be used on all fires as well as dry chemical
What fire do use a carbon dioxide fire extinguisher on?
A CO2 fire extinguisher will work on flammable liquid and electrical fires only. If used on any other type of fire they will just give it more oxygen and it will spread.
Why do cars work with gasoline and not water?

What safety precautions should be taken when handling the most flammable liquid?
When handling the most flammable liquid, it is important to wear protective gear such as gloves and goggles, work in a well-ventilated area, keep the liquid away from sources of ignition, and have a fire extinguisher nearby. Additionally, it is crucial to follow proper storage and handling procedures to prevent accidents and ensure safety.
What is the safest way to heat up a flammable liquid in a test tube?
The safest way to heat up a flammable liquid in a test tube is to use a water bath or a heating mantle to provide indirect heat. Never use a direct flame, as this can lead to ignition of the flammable liquid. Ensure proper ventilation and keep a fire extinguisher nearby as a precaution.
How does the process of condensation work on earth?
Condensation is the process where water vapor comes together to form liquid water (or any other liquid).
Do buoyancy work only in water If No then where else can it work?
Buoyancy can work in any liquid provided that the object floating weighs less than the liquid it displaces. This is true regardless of whether it is water or not! Buoyancy works in any fluid. The fluid can be any liquid, or any gas.
What should you do before you start an experiment with flammable liquid?
Before starting an experiment with a flammable liquid, you should ensure you have a fire extinguisher nearby, work in a well-ventilated area, avoid any open flames or sources of ignition, and wear appropriate personal protective equipment such as safety goggles and gloves.
