Flammability diagrams show the control of flammability in mixtures of fuel, oxygen and an inert gas, typically nitrogen. Mixtures of the three gasses are usually depicted in a triangular diagram, known as a ternary plot. Such diagrams are available in the speciality literature. [ 1][ 2][ 3] The same information can be depicted in a normal ...
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 ...
A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.
The limiting oxygen concentration is shown in the lower right of the diagram. The limiting oxygen concentration ( LOC ), [ 1] also known as the minimum oxygen concentration ( MOC ), [ 2] is defined as the limiting concentration of oxygen below which combustion is not possible, independent of the concentration of fuel.
A flammable liquid is a liquid which can be easily ignited in air at ambient temperatures, i.e. it has a flash point at or below nominal threshold temperatures defined by a number of national and international standards organisations. The Occupational Safety and Health Administration (OSHA) of the United States Department of Labor defines a ...
Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion),The air–fuel ratio determines whether a mixture is combustible at all, how much energy is being released ...
It is a colorless, flammable, slightly greasy liquid of great industrial value. [3] The mixture is referred to as both xylene and, more precisely, xylenes. Mixed xylenes refers to a mixture of the xylenes plus ethylbenzene. The four compounds have identical molecular formulas C 8 H 10.
Propane is a colorless, odorless gas. Ethyl mercaptan is added as a safety precaution as an odorant, [ 23] and is commonly called a "rotten egg" smell. [ 24] At normal pressure it liquifies below its boiling point at −42 °C and solidifies below its melting point at −187.7 °C.
