Knowing How Fire Extinguisher Works In Houston
Every office or home needs to have a fire extinguisher. Even though the fire extinguisher may not see a use for many years, it still good to have in case of an emergency because it can still provide protection for you and your property.
We’ll give more information about the role of fire extinguishers and how they work in this article. Also, we’ll go deeper into what causes fires, proper fire extinguisher usage, and fire types and fire suppressants that can counteract them.
When a fuel, such as gasoline or wood, interacts with oxygen, the result is a chemical combustion reaction, which results in a fire. The fuels simply being around oxygen isn’t enough to make a fire break out spontaneously. Each fuel has an ignition temperature, and they have to reach that temperature in order for the combustion reaction to take place.
Oxygen in the air, along with a fuel such as gasoline or wood, can combine in a combustion reaction to create fire. Gasoline and wood won’t just start burning on their own, no matter how much oxygen is present. The ignition temperature of the fuel has to be reached before the combustion reaction that creates a fire can begin.
This is what usually happens when a wood fire occurs:
- The wood is heated to high temperatures by something. Friction, light, an already burning source, or anything else can cause this.
- Upon reaching a temperature of 500 degrees Fahrenheit or 260 degrees Celsius, the cellulose material of the wood is decomposed by heat.
- This decomposition causes volatile gases, usually oxygen, hydrogen, and carbon compound, to be released.
- Once this gas reaches a certain temperature, it breaks down into atoms and creates carbon dioxide, water, and other things after mixing with the oxygen.
- As the gases rise, the flame is created. The light from the lame is the emission of carbon atoms that rise when their temperatures rise.
- The ignition temperatures of the fuel are maintained by the heat coming from the flame, resulting in a continuous burn in the presence of oxygen and fuel.
In order for a fire to be made, three elements must always be present:
- Extreme heat
- Oxygen or a gas similar to it
At least one element of the fire formula is removed when fire extinguishers are used, resulting in the fire being eliminated. As you will see in the following section, there are multiple ways of doing this.
- Removing one of these elements is crucial to successfully put out fires.
- Putting water on a fire is the best way to take heat away from it. This interrupts the combustion cycle by making the fuel cooler than its ignition point.
- Oxygen can also be removed from fire by smothering it to prevent air exposure. This can be done by using a heavy blanket to cover the fire. Baking soda or any other nonflammable material can also be dumped onto a fire in order to smother it.
- The hardest way of putting out a fire is removing fuel from it. House fires really showcase how difficult it is to do this, as the entire house is a potential fuel source for the fire. In this instance, the only way that the fuel will be removed is when the fire has finished burning everything.
