Although not as widely used as others, there are water-based fire extinguishers, commonly known as Air Pressured Water (APW) extinguishers. These extinguishers extinguish flames of Classes A, B, and C, the most common types of household fires. Electrical fires are caused by a number of factors, including defective equipment, outdated or broken electrical wiring, improper use of electrical outlets, and faulty circuit breakers. When oxidation produces heat faster than it can be released, the combustion which starts the chemical reaction of fire occurs. [7] Thus, while heat is important to ignite a flame, topography is important for aiding fire spread especially by preheating upslope fuels, and ignitions sources are important to help explain recurrence on longer time scales. Fuel separation is an important factor in wildland fire suppression, and is the basis for most major tactics, such as controlled burns. It does not store any personal data. The fire triangle is used to show the three elements that when present together can cause a fire to start. There are three different approaches on doing so. If just one of these components is removed, the fire triangle will collapse and the fire will be extinguished.
