The word "inflammable" may be erroneously thought to mean "non-flammable". [3] The erroneous usage of the word "inflammable" is a significant safety hazard . Therefore, since the 1950s, efforts to put forward the use of "flammable" in place of "inflammable" were accepted by linguists, and it is now the accepted standard in American English and ...
Lower flammability limits for many organic materials are in the range of 10–50 g/m 3, which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours. Dust clouds of this concentration are hard to see through for more than a short distance, and normally only exist inside process equipment.
The air–fuel ratio is at the bottom region of the flammability range (i.e. lean). A rich flashover occurs when the flammable gases are ignited while at the upper region of the flammability range (i.e. rich). This can happen in rooms where the fire subsided because of lack of oxygen.
Flammable range, limits: The percentage mixture of fumes with air that will sustain fire; outside the limits the mixture is either too lean or too rich to burn. Flash point: Lowest temperature at which a material will emit vapor combustible in air mixture. Higher than Flame point of same material.
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
The lower flammability limit (LFL), [1] usually expressed in volume per cent, is the lower end of the concentration range over which a flammable mixture of gas or vapour in air can be ignited at a given temperature and pressure. The flammability range is delineated by the upper and lower flammability limits. Outside this range of air/vapor ...
A certain concentration of a flammable or combustible vapor is necessary to sustain combustion in air, the lower flammable limit, and that concentration is specific to each flammable or combustible liquid. The flash point is the lowest temperature at which there will be enough flammable vapor to support combustion when an ignition source is ...
Hydrogen sulfide is a highly toxic and flammable gas (flammable range: 4.3–46%). It can poison several systems in the body, although the nervous system is most affected. [ citation needed ] The toxicity of H 2 S is comparable with that of carbon monoxide . [ 51 ]
