What puts out fire the fastest?
Grease Fire Sprinkle baking soda or salt on the grease. This will quickly absorb it and will put out the fire out at its source. You can also use a fire extinguisher on a grease fire, but DO NOT use water or flour. Flour can make it worse and water does not mix with oil, hence it would only cause the fire to spread.
Can fire put out fire?

Fire Extinguishers: Your First Line of Defense Against Fires.
What is an example of a Class D fire?
Class D. The Class D fire is defined as one that uses a combustible metal as its fuel source. Examples of such combustible metals include titanium, magnesium, aluminum, and potassium. When confronted with such a fire, common extinguishing agents such as water are ineffective and can be hazardous.
What protocol is used to respond to a fire?
When smoke or fire is detected, two mnemonics can help you remember the vital steps to follow. Right away, you need to implement the RACE protocol: rescue, alert, confine, and extinguish and evacuate. Rescue. Size up the fire scene and determine whether entering the immediate area is safe.

Will water put out a fire?
Why Does Water Put Out Fire? – Water creates a barrier between the oxygen and the fuel, cooling the fire and removing its heat source. Water mixing with any electrical circuit that is live can cause a short and spark a fire. Water is a conductor so will not extinguish an electrical fire.
Is water stronger than fire?
Water can be more powerful in its devastation than fire or wind, because it doesn’t always come by the bucketful. When it chooses to, water can over .
Can there be fire in water?
In fact, fire can burn under water, too… Normally, water puts out a fire by stopping two of the three parts of the fire triangle – oxygen is harder to get out of water, and the water sucks away the heat. And if it’s hot enough, water can’t suck away the heat. Or the fire can rip oxygen out of the water.
Why does fire not burn in water?
Hydrogen is flammable, but oxygen is not. When hydrogen combines with oxygen the result is water, where the atoms of hydrogen and oxygen are linked together to make a molecule with entirely different properties. You can’t burn pure water, which is why we use it to put out fires instead of starting them.
Does napalm burn underwater?
Napalm is basically thick oil or jelly mixed with fuel (petrol, gasoline). Versions of Napalm B containing white phosphorus will even burn underwater (if there is trapped oxygen in folds of cloth etc.) so jumping into rivers and lakes won’t help those unfortunate souls attacked with this vile weapon.
