Ignition risks can be minimized by controlling heat sources and using materials that will not ignite or will not support burning in the applicable environment. Some materials are more susceptible to ignition in oxygen-rich environments, and compatibility should be assessed before a component is introduced into an oxygen system. [ 1 ]
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.
The Journal is the first student-run journal of law and economics in legal academia. [3] The journal is cited widely throughout state and federal courts, including notably in an opinion by D.C. Circuit U.S. federal judge Neomi Rao in District of Columbia v. Exxon Mobil Corp. [4] It also holds symposia regularly on relevant legal challenges. [5]
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.
Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost over ...
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.
Hot work is a process that can be a source of ignition when flammable material is present or can be a fire hazard regardless of the presence of flammable material in the workplace. Common hot work processes involve welding , soldering , cutting , brazing burning and the use of powder-actuated tools or similar fire producing operations outside ...
