If you are in a closed garage when this happens, you are in danger of breathing this gas. Death may result. A person should never run the engine of an automobile in a closed garage. Most people who are killed in fires in buildings die from inhaling carbon monoxide. Both smoldering fires and too little oxygen following flashover can promote the production of this gas.
Smoke is a mixture of soot and other particles with the gases produced by combustion.
Smoke from fires can contain carbon monoxide and other poisonous gases. The soot and particles hamper vision and thus can make it difficult to escape from fires. In general, smoke results from incomplete combustion, which wastes energy and pollutes the environment. Light Most of the energy caused by a fire goes into heat, but some of it goes into light. The light results either because the carbon particles in the flame become so hot that they give off light energy, or because the gas that is burning is a type that gives off light.
