WebSep 10, 2002 · Question: Does 29 CFR 1910.124(b)(1) require an employer to maintain the airborne concentration of vapors at levels below 25 percent of their lower flammable limits (LFL) within the "vapor area"? Reply: No. A "vapor area" is defined in 29 CFR 1910.123(d) as "any space containing a dip tank, including its drain boards, associated drying or ... WebJun 29, 2015 · A similar behavior is observed for the upper flammable limit of propane. The data presented include lower and upper flammable limits, maximum pressures, and maximum rates of pressure rise. The rates of pressure rise, even when normalized by the cube root of the chamber volume (V l/3), are shown to be sensitive to chamber size.

Lower flammability limit (LFL): The lowest concentration (percentage) of a gas or a vapor in air capable of producing a flash of fire in the presence of an ignition source (arc, flame, heat). The term is considered by many safety professionals to be the same as the lower explosive level (LEL). At a concentration in air lower than the LFL, gas mixtures are "too lean" to burn. Methane gas has an LFL of 4.4%. If the atmosphere has less than 4.4% methane, an explosion cannot occ… marchela arielWebThe upper and lower flammability limits of methane in air are located on this line, as shown. The stoichiometric combustion of methane is: CH 4 + 2O 2 → CO 2 + 2H 2 O. The stoichiometric concentration of methane in oxygen is therefore 1/(1+2), which is 33 percent.
