Four things are necessary at all extintores de incendio tipos for the reaction to continue—oxygen, fuel, heat, and an uninhibited chain reaction. The oxygen in the air is sufficient to support extintores de incendio tipos. Some sort of fuel is required, such as wood, paper, or gasoline.
However, wood and gasoline do not spontaneously catch fire just because they are surrounded by oxygen. For the chemical combustion reaction to take place, the fuel has to be heated to its ignition temperature by some outside source.

The source of ignition might include a burning cigarette, overheating equipment, welding, static electricity, or a chemical reaction.
Once extintores de incendio tipos, the heat of the flame keeps the fuel at the ignition temperature, so it will continue to burn as long as there are fuel and oxygen. Discuss some possible sources of ignition in your workplace. Wood, pallets, lumber; Paper and cardboard; Plastic and foam; and Garbage.
Quais as diferenças entre os extintores e para que servem?
Make sure you know what types of ordinary combustibles are present in your facility. Discuss the types of ordinary combustibles in your workplace. Grease that is often found in the kitchen; Gasoline, kerosene, and other fuels; Oil and other combustible liquids; extintores de incendio tipos Common solvents such as paint thinners, mineral spirits, and common organic solvents found in a laboratory.
Also, know the types of flammable liquids in your facility. Discuss the types of flammable liquids in your workplace.
FUEGOS Y TIPOS DE EXTINTORES ABORDO by Gina Chalacan on Prezi
Appliances, including stoves, washing machines, dryers; Switches, outlets, power cords, extension cords; Panel boxes and circuit breakers; and Power tools, including drills, sanders, grinders, and saws.
Know the types of energized electrical equipment in your facility. Discuss the types of energized electrical equipment in your workplace. Magnesium metals, chips, extintores de incendio tipos grinding dusts that can be found in some metal shops.
Titanium metals, chips, or grinding dusts that can be found in many aerospace sheet metal companies. Potassium and sodium, which in their extintores de incendio tipos elemental forms are soft, ductile, malleable metals that can be easily cut with a knife or drawn into a wire.
These metals are reactive toward air and water and are usually stored in a substance such as mineral oil.
Extinguishing a potassium fire with water could result in an explosive reaction. Finally, pyrophoric materials, which are highly reactive substances that are useful in the synthesis of organic chemicals. Special training is required to store and handle these materials safely.
Examples include alkyllithiums, alkylmagnesiums, and diphosphine. A Class D fire extinguisher must be on hand when handling extintores de incendio tipos materials.
An improper extinguisher could result in a larger fire—for example, a carbon dioxide extinguisher used on an alkylmagnesium fire would actually cause the fire to burn more intensely.
Know the types of combustible metals in your facility. Discuss the types of combustible metals in your workplace.
