WebDec 31, 1995 · Ammonia`s flammability limits in air at standard atmospheric conditions are 14.8% (lower flammability limit, LFL) and 33.5% (upper flammability limit, UFL) concentration of ammonia by volume in air. Lower pressures tend to narrow the flammability limits and, as temperature increases, the LFL is decreased. Web4.1. Hydrogen Flammability Limits Flammability of hydrogen occurs between specific limits. These limits are a function of temperature, pressure, diluents, and ignition energy. Concentration limits are normally expressed as percent by volume (%v/v). For hydrogen in an air mixture, the Lower Flammability Limit (LFL) and Upper Flammability
