WebThe lower explosive/flammability limit for both 70% ethanol (intended for drinking) and denatured alcohol is 3.3% by volume in air. When Charlie was sprayed on the Victim and visible flame was observed, the percent of denatured alcohol had to be between 3.3% and 19.0% by volume in air in the presence of an ignition source. WebSep 19, 2024 · One hundred percent lower explosive limit (100% LEL) denotes an atmosphere in which gas is at its lower flammable limit.
