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). There are also many other ways to bring sufficient activation energy including electricity, radiation, and pressure, all of which will lead to a temperature ...
As batteries became more common in cars (due to the increased usage of electric starter motors), magneto systems were replaced by systems using an induction coil.The 1886 Benz Patent-Motorwagen and the 1908 Ford Model T used a trembler coil ignition system, whereby the trembler interrupted the current through the coil and caused a rapid series of sparks during each firing.
Division 4.2: Spontaneously Combustible . Spontaneously combustible material is: Pyrophoric Material: A pyrophoric material is a liquid or solid that, even in small quantities and without an external ignition source, can ignite within five (5) minutes after coming in contact with air when tested according to the UN Manual of Tests and Criteria.
Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to electrical arcing , or high temperatures.
These measures may include installation of fire sprinklers or storage remote from possible sources of ignition. Substances with low combustibility may be selected for construction where the fire risk must be reduced, such as apartment buildings, houses, or offices.
The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
Residential fire sources of ignition, 6 jurisdictions, 2014 [1] Ignition source Examples Percentage Cooking equipment: stoves, hot plates, BBQs, deep fryers: 33% Smoker's material and open flame: cigarettes, lighters, matches, candles, lanterns, blow torches: 24% Heating equipment: central heating, space heaters, wood stoves, fireplaces: 14%
There are many sources of ignition, and a naked flame need not be the only one: over one half of the dust explosions in Germany in 2005 were from non-flame sources. [7] Common sources of ignition include: electrostatic discharge (e.g. an improperly installed conveyor belt, which can act like a Van de Graaff generator) friction; electrical ...
