LEL – Lower Explosive Limit. UEL – Upper Explosive Limit, PPM – Parts per Million, Density (lighter than air, heavier than air)
These terms provide a starting point to understanding hazard management around explosive and flammable materials. Beyond the common flammable liquids like gasoline and diesel fuel, liquid propane and compressed natural gas, there are dozens of other flammable materials available and in use by industry every day.
Life Safety and Hazardous Material Emergency Alarm Systems provide the first warning and the last line of defense around these dangerous flammable materials. They operate by sensing at extremely low levels and then activating ventilation controls, material shutoffs and other mitigation steps to limit the danger.
