Smokey redirects here. For the mascot of the United States Forest Service, see Smokey Bear . ]] Smoke is a Suspension in Air ( Aerosol ) of small particles resulting from incomplete Combustion of a Fuel . It is commonly an unwanted By-product of fires (including Stove s and Lamp s) and fireplaces, but may also be used for Pest Control (cf. Fumigation ), communication ( Smoke Signals ), defense ( Smoke-screen ) or Inhalation of Tobacco or other Drug s. Smoke is also sometimes a component of Internal Combustion Engine Exhaust Gas , particularly Diesel Exhaust . Smoke Inhalation is the primary cause of Death in victims of indoor Fire s. The smoke kills by a combination of thermal damage, Poison ing and Pulmonary irritation caused by Carbon Monoxide , Cyanide and other combustion products. Smoke particles are actually an Aerosol (or Mist ) of solid particles or liquid droplets that are close to the ideal range of sizes for Mie Scattering of Visible Light . This effect has been likened to three-dimensional textured privacy glass—the smoke cloud does not obstruct an image, but thoroughly scrambles it. VISIBLE AND INVISIBLE PARTICLES OF COMBUSTION Depending on particle size, smoke can be Visible or Invisible to the Naked Eye . This is best illustrated when toasting bread in a toaster. As the bread heats up, the products of Combustion increase in size. These particles begin as invisible but become visible if the toast is Burnt . SEE ALSO
