A flammability detection system (15) includes the detector (16) and a controller, annunciating signal when the fuel/air mixture concentration is equal to or between the upper and, Substances need not be classified as Polymeric beads, expandable if the concentration, have a flammable range with air of at least # percentage points regardless, b) have a flammable range with air of less than # percentage points regardless, b)have a flammable range with air of at least # percentage points regardless, b) have a flammable range with air of at least # percentage points regardless, have a flammable range with air of at least 12 percentage points regardless, or(b) have a flammable range with air of at least # percentage points regardless, the gas has to be within the range that the gas is capable, Substances need not be classified as Polymeric beads, expandable or Plastics moulding compounds, evolving, gas or vapour that will burn or explode in the presence. Fuel or combustible volumetric concentrations below LFL are non-flammable and are considered safe. A-GG-040-005/PT-001 Basic Safety Officer Training Course Lower explosive (flammable) limit (LEL or LFL) - The lower explosive limit or lower flammable limit of a vapour or gas; the lowest concentration (lowest percentage of the substance in air) that will produce a flash of fire when an ignition source (heat, arc, or flame) is present.

Lower flammability limit (LFL) refers to the lower limit of the gaseous or vaporized fuel, combustible material or dust’s concentration in the air, at a fixed temperature and pressure, which can lead to flame propagation, detonation or an explosion.

They come from many sources and are not checked. ). The concentration is generally expressed as percent fuel by volume.. in air are: lower 3.6 volume% and upper 33.0 volume%. Thirdly, although hydrogen has flammability limits of 4-75%, its explosive limits are different at 17-56%, and its very low vapour density means it will tend to dissipate harmlessly into the atmosphere (look at hydrogen vehicle fires online and see how well they compare to petrol! and require different levels of electrostatic discharge energy to ignite. Historically, flammable, inflammable and combustible meant capable of burning. By using our services, you agree to our use of cookies. The lower and upper flammability limits of a fuel are key tools for predicting fire, assessing the possibility of explosion, and designing protection systems. https://encyclopedia2.thefreedictionary.com/flammability+limits.

LEL (Lower Explosive Limit) If you spend much time working with Calibration Gas it's very likely that you will see the term LEL used extensively.LEL, short for Lower Explosive Limit, is defined as the lowest concentration (by percentage) of a gas or vapor in air that is capable of producing a flash of fire in presence of an ignition source (arc, flame, heat).
