LEL stands for the Lower Explosive Limit of a gas. It is the minimal concentration of the gas required for the gas to ignite. It is normally expressed as a percentage of the total air. PPM stands for parts per million. It also is a measure of concentration, though it is often provided by gas meters.

-Due to added odorants, people can often begin smelling a gas leak at 1% LEL whereas available retail gas alarms set an alarm threshold of 5%-25% LEL to avoid frequent false alarms. Do not be alarmed if you smell gas before the device alarms.-Every couple weeks, test your alarm with unlit butane from a cigarette lighter or propane source.
