To understand the matter first one needs to know about the nature and religion of fire. Fire is a chemical reaction that produces heat and light. There are three necessary conditions for ignition. First, the presence of some fuel is essential. wood,

Examples of fuels are paper, coal etc. Second, there must be a good supply of oxygen. Third, the fuel must be heated until it
reaches its ignition temperature. Fuel can reach its ignition temperature only through heat. When a substance burns, it has a certain temperature at which the substance becomes ignited. That temperature is called ignition temperature. When the fuel reaches its ignition point, it begins to burn. However, its combustion is carried out with the help of atmospheric oxygen.
So fire can be extinguished in three different ways. Methods remove any one of the three conditions necessary for ignition. First, remove the fuel. Second, stop the supply of oxygen. Third, reducing the heat of the fire so that the temperature falls below the ignition temperature. When water is sprinkled on fire, the temperature decreases. As the water absorbs heat from the burning material, its temperature decreases. Once the temperature falls below the ignition temperature, the fuel no longer burns. Spraying water is more effective in extinguishing fire.
In case of oil fire, oil floats on top of water as oil is lighter than water. In that case, if the fire is extinguished by sprinkling water, the fire may spread to more places. Extinguishing an electrical fire with water is likely to result in electrocution. Carbon dioxide fire extinguishers are used to extinguish such fires. Carbon dioxide blocks the supply of oxygen. As a result, the fire can no longer burn.
The best way to put out a cooking fire is to “snuff it out”. You want to cut the flow of air to the fire. Here are some options:
how to put out a fire in a fireplace
• If the fire is small enough, cover it with a metal cooking lid or cookie sheet. Keep it covered until it has cooled.
• Cover the fire with a fire blanket, a large piece of fire-resistant material such as fiberglass.
• Don’t swat at the flames. This could create airflow and make the fire worse, or ignite your clothes.
• Pour a large quantity of salt or baking soda over the fire. Make sure it is salt or baking soda and not flour. Flour adds fuel to the fire and will cause it to burn (or even explode).
• Turn off any heat source.
• If your fire is in the oven or microwave, keep the door shut. While it may look scary, the lack of air will eventually extinguish the fire.
Fire extinguisher is a fire extinguisher used to extinguish or control fire. In most conventional fire extinguishers, liquid carbon dioxide stored in high pressure cylinders is sprayed out in the form of a spray to put out the fire.
What is the easiest way to put out a fire?
• 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.

Never use water on a class F fire as this could strengthen the spread. Instead, use wet chemical fire extinguishers, created specifically to tackle cooking oil fires. These extinguishers have been made with a special formula that is designed to layer the oil and ‘seal it’, thus quenching the flames and reducing the chance of reignition
What if the extinguisher doesn’t put out the fire?
Remember, you are not a professional. If the fire extinguisher is failing to put out a fire, you must get to safety immediately and call the emergency services. Another key tip is to always ensure that you know the fire safety procedures or your workplace or place of residence. If you are a responsible person of a workplace, you must also ensure these policies are kept regularly up to date.
“There was no explosion as posted by the Calbayog Journal earlier. It was an isolated case that accidentally caused fire in the burner but was immediately and totally put-off by the kitchen staff themselves using readily available fire extinguisher tanks and leaving only smoke when they left the area. -The smoke that was seen and captured in the video that has circulated in the social media.”
