Potential ignition sources are present in almost all oxygen systems, but fire hazards can be mitigated by controlling the risk factors associated with the oxygen, fuel, or heat, which can limit the tendency for a chemical reaction to occur.
A small amount of fuel in the tank leaves pumps on the floor of the tank exposed to the air-fuel mixture, and an electric pump is a potential ignition source. The explosion of a Thai Airways International Boeing 737 in 2001 and a Philippine Airlines 737 in 1990 also occurred in tanks that had a small amount of residual fuel.
The Skydrol series of phosphate ester hydraulic fluids were originally jointly developed by the Douglas Aircraft Company and Monsanto in the late 1940s to reduce the fire risk from leaking high pressure mineral oil-based hydraulic fluids impinging on potential ignition sources.
Consider also storing sawdust in a sealed metal container away from any potential ignition sources. Vlad Yushinov/istockphoto. 12. Blocked Air Vents in Electronics.
Introducing sufficient quantities and types of powder or gas in the flame reduces the amount of heat available for the fire reaction in the same manner. Scraping embers from a burning structure also removes the heat source. Turning off the electricity in an electrical fire removes the ignition source. Without fuel, a fire will stop.
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.
Because the mixture by definition is ignitable before inerting commence, it is imperative that the inerting procedure does not introduce a potential source of ignition, or an explosion will occur. NFPA 77 states [2] that carbon dioxide from high-pressure cylinders or fire extinguishers should never be used to inert a container or vessel.
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
