For a fire to start, survive, and spread heat, fuel and oxygen is required along with chemical chain reaction—the typical fire triangle or Tetrahedron (Fig. 8.28). Fire may be controlled or is extinguished by influencing at least one or a combination from the four elements (Fig. 8.29). ...
Fire triangleEnergyFuelOxidantAlthough fire is no more than an exothermic chemical reaction, it can cause untold damage. The fire triangle is a simple training aid that aims to show how fire can be prevented if any one of the three elements needed for a fire to happen - i.e. energy, ...
All fire extinguishers work on the basic principle of removing any of the three basic elements needed for combustion—oxygen, heat or fuel. Since their creation two centuries ago, fire extinguishers have played an integral part in saving lives being threatened by a perilous fire. Fire triangle. ...
将“fire triangle"翻译成意大利文 triangolo del fuoco是将“fire triangle"翻译成 意大利文。 译文示例:In other words, besides the original “fire triangle” of fuel, heat and oxygen, they add the fourth essential of chemical reaction. ↔ In altre parole, oltre all’originale “triangolo del...
Fire is a chemical reaction that occurs when oxygen, fuel, and heat combine in a certain way. These three things make up what is called the “fire triangle.” Without one of these things, the fire will not continue. For example, if there is no oxygen in a certain area, a fire will...

EXPLAIN HOW IT SHOWS “FIRE TETRAHEDRON”--FOUR-SIDED FIGURE SHOWING RELATIONSHIP BETWEEN COMPONENTS OF COMBUSTION PROCESS (UPDATE FROM OLD “FIRE TRIANGLE”--ADDS CHEMICAL CHAIN REACTION AS FOURTH ELEMENT). EXPLAIN THAT EACH COMPONENT IS EQUALLY IMPORTANT. ASK “HOW DO YOU PUT OUT A FIRE?” (...
What do you need for a fire? Oxygen, heat, and fuelare frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will no...
They use a dry chemical powder, monoammonium phosphate, which smothers the fire by interrupting the chemical reaction of the fire triangle (fuel, heat, and oxygen). Due to their versatility, ABC extinguishers are ideal for offices, homes, schools, and commercial spaces, making them a crucial ...
This is the Fire Triangle. Actually it's a tetrahedron, because there are four elements that must be present for a fire to exist. There must be Oxygen to sustain combustion, Heat to raise the material to its ignition temperature, Fuel to support the combustion and a Chemical Reaction between...
