Limited Oxygen Concentration (LOC) testing is a process used to determine the minimum oxygen level at which a substance can ignite, helping to prevent fires and explosions in environments with flammable gases, vapors, or dust. During the test, the oxygen concentration is gradually reduced in a controlled setting, usually by adding inert gases like nitrogen. An ignition source, such as a spark, is applied at various oxygen levels to see when the material ignites. The lowest oxygen concentration that still allows ignition is recorded as the LOC. Keeping oxygen below this concentration minimizes combustion risks, making LOC testing crucial for industries like chemical, pharmaceutical, and food processing, where controlling explosion hazards is a priority.
