Extreme cooling effect
- Water has an extreme cooling effect. When it is directed at flames, it lowers the overall temperature, making it impossible for the fire to burn.

Why is water a good way to put out a fire?
When water extinguishes a fire, it does so because it doesn’t break down into its constituent elements. The water molecule doesn’t become hot enough to separate into hydrogen and oxygen and instead, has two potential actions on the fire that can put it out.
Oct 14, 2014 · Water can accelerate liquid hydrocarbon fires by dispersing fuel. Water can generate explosive gaseous mixtures when applied to some charcoal fires. Water can react with some metals and chemicals to directly accelerate the fire. Water exothermically reacts with nuclear fuel element cladding under accident conditions to generate explosive hydrogen.

Whether you're camping, cooking, or just minding your own business, knowing how to put out a fire properly will help you be prepared for any situation. If you feel that a fire is too large or dangerous for you to put out, don't hesitate to call the fire department.
For kitchen fires, turn off the appliance and keep the door of your microwave or oven shut to suffocate the fire, or place the lid on your skillet.
Sprinkle a generous amount of baking soda onto a grease fire to put it out safely. Avoid using water or flour, as these may intensify the fire.
Or, pull the pin on the handle of a fire extinguisher, then aim the nozzle at the fire and squeeze the handle.
Determine whether it is appropriate to use a fire extinguisher.
Certain types of fires are unsuitable for a fire extinguisher. If the fire is out of control, then do not use a fire extinguisher and get the help of the fire department.
Identify the appropriate type of fire extinguisher for the type of fire.
Depending on the fire, different extinguishing agents may need to be used to put the fire out.
Class A fire extinguishers can be used for trash, wood, and paper fires.
Class B fire extinguishers can be used for flammable liquids, such as oil or grease.
Determine whether it is appropriate to use a fire blanket.
Certain types of fires are unsuitable for a fire blanket. If the fire is out of control, then do not use a fire blanket and get the help of the fire department.
Place the fire blanket on top of the fire.
After removing the fire blanket from its pouch, put the fire blanket on top of the fire. If a person's clothes is on fire, have them stop, drop, and roll.
It may take several minutes for a fire to be completely smothered by the fire blanket. Keep the fire blanket on the fire, and do not lift the blanket back up until it has completely cooled down.
If the fire is not successfully extinguished within a few minutes of using the fire blanket, then the fire is too large to manage. Leave the area and call the fire department. Even if you successfully extinguish the fire, the fire department can help manage hotspots that may reignite.
Cut off the oxygen of microwave or oven fires.
If something flames up in the oven or the nuke machine, stay calm. Turn off the device, close the door, and watch it closely. Closing it off and eliminating the heat source should make small fires die down quickly. Get your fire extinguisher and watch it closely.
If the fire doesn't die down, open the door very carefully and spray it with the extinguisher to put the fire out. If you have any trouble whatsoever,
call the fire department immediately.
Put a lid on it.
If you've flamed up something in the skillet, use the lid (or a lid of larger size) to clap on quickly and smother it. This is the quickest and most effective way of stopping the fire.
Keep the fire well maintained
While you're enjoying a campfire, make sure to keep it manageable. Don't make it any bigger than is necessary for your group, and keep it burning steadily with large pieces of dry wood. Don't include any green or live wood in your fire and always stay close by, supervising.
Make sure the fire pit is of an appropriate size and of good quality before building your fire. Consider reinforcing pre-made metal pits by piling up dirt or rock to keep the fire housed safely and burning properly.
Do NOT burn glass, aluminum cans, or any kind of pressurized aerosol. These objects won't burn and will be extraordinarily dangerous when they heat up.
Don't include any large logs in your campfire if you're aiming to keep the fire small and short-burning.
Allow the fire to burn down before extinguishing it.
Look at what resources are available to contain the fire.
If you are near a source of water from a pressurized system, and have sufficient hoses available, use them to extinguish minor fires, and wet the potential fuel in the immediate area.
Use a tool to create a "fire break" if no water is available.
Dig a shallow trench around the perimeter of the blaze, or scrape potential fuel away, exposing as much bare earth as possible. Concentrate on the area "downwind" of the flames, since the wind will push the blaze in that direction.
Use heavy equipment, if available, to create a larger firebreak if the situation warrants it. A farm tractor with a disk, a bulldozer, or other equipment can quickly establish a sizable fire break.
Try to extinguish the fire with water.
Always keep a good quality fire extinguisher in your house.
Consider having a few in easy to reach locations and make sure everyone in your household knows how to use them. Keep one in the basement, one in the kitchen, and one elsewhere in the house, like near the sleeping quarters. They're good for several years, but get them tested out regularly and recharged to make sure they'll be ready when you need them.
Keep your fire alarms in good working order.
Check your fire alarms every month to make sure the batteries are in good condition and change them out regularly. Having the right warning system in place can give important extra minutes that can be the difference between an inconvenience and a disaster.
Maintain your electrical appliances regularly.
Never overload outlets or power strips with chords. Avoid plugging in more chords than an outlet can handle to eliminate the possibility of dangerous electrical fires. Regularly unplug unused appliances to avoid needless circuits.
Jun 28, 2016 · Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor).
How does water extinguish fires? Water is an effective fire extinguishing agent because it cools the fuel source and removes heat from the fire triangle. When water is applied to a fire, it absorbs heat from the flames and surrounding area, lowering the temperature and reducing the fire's intensity.
Jun 4, 2022 · When water hits a fire, it cools down the flame and dampens the oxygen supply to the flame. The water then absorbs some of the heat from the fire. This cooling effect reduces the temperature of both water and air, as well as reduces the amount of oxygen available for combustion.
