The three elements must be combined in the right proportions for a fire to occur. For a fire to start, the three components must be combined in the correct proportions. As we said, the three sides of the triangle or the three essential components of fire are fuel, heat and oxygen. So, if a fire runs out of fuel, it will smoulder out; if you can cool a fire down it will lose heat and go out; and if the oxygen is removed it will suffocate. Fuel A fire cannot ignite without an object or material present to enable the fire to burn. You should also have a good bed of embers now to keep the fire sustained. Surgical fires occur in, on, or around a patient who is undergoing a medical or surgical procedure. 3. In this case, water droplets are evaporated in the gas phase, thereby lowering the temperature and adding water vapour making the gas mixture non combustible.

In addition, they suppress fires involving trash, wood, and paper (Class A), liquids and gases (Class B), and electrical fires that have been electrified (Class C). Similarly, while oxygen is relevant to sustain a flame, weather and associated winds feed oxygen into a spreading fire, and the longer-term pattern of weather is summarized as climate. Ignorance Breeds Fear, Introducing sufficient quantities and types of powder or gas in the flame reduces the amount of heat available for the fire reaction in the same manner. If no efforts are made to extinguish a fire, it will extinguish on its own after all of the fuel has been consumed. The Fire Triangle. Three things are required in proper combination before ignition and combustion can take placeHeat, Oxygen and Fuel. When 3 elements of the fire triangle combine what can occur?

When leaving a room, space heaters must always be turned off. Class A fires involving solid materials such as wood, paper or textiles. 1. If one of the three components is removed, the fire is extinguished. Water can be used to lower the temperature of the fuel below the ignition point or to remove or disperse the fuel. Several examples include friction, as in the case of matches, heating an electrical wire, a flame (propagation of fire), or a spark (from a lighter or from any starting electrical device). Want more??? The fire triangle, which investigates the physics of fire, is often used in basic fire safety teaching. Typically, this entails performing controlled burns before the larger fire to reduce potential fuels. Weaken any one, and the fire While training them about fraud, controls and risks, they introduced me to the fire triangle which states that for a fire to occur, three elements are necessary: (1) heat, (2) fuel and (3) oxygen. The colors of the flame may be utilized to determine the fire's temperature. To the contrary, if air is blown over a wood fire (as with bellows), the fire is activated by the introduction of more air.
