Methane (CH4) is the simplest hydrocarbon and the main component of natural gas. It is a colourless, odourless, non-toxic, and highly flammable gas. While considered non-toxic in the traditional sense, it is an asphyxiant at high concentrations by displacing oxygen in the air.

The table above provides the LEL for select combustible gases*. It also provides correlation factors that help the safety technician and instrument operator determine the actual percentage LEL when the sample gas differs from the gas that was used to calibrate the unit.
For example, if the unit reads 10% LEL in a pentane atmosphere, and was calibrated to methane, the actual percentage LEL is determined as follows:
1. Locate the table cell where the sample gas (pentane) intersects with the calibration gas (methane).
2. Multiply the cell’s value (2.02) by the unit’s LEL reading (10%) to calculate the actual concentration of 20.2% LEL.
*The combustible gas list is not a comprehensive list of all combustible gases that can be detected by the MX6. For additional information about combustible gas detection and the MX6, contact the Industrial Scientific Technical Service department.
