What is the % volume of Methane at its lower explosive limit?

The lower explosive limit (LEL) of methane is established at approximately 5% by volume in air. This means that when the concentration of methane in the air reaches this level, it is capable of igniting and potentially causing an explosion when an appropriate ignition source is present.

Understanding the LEL is crucial for safety in mining operations where methane is a common hazard. Monitoring the concentration of methane in the air can help miners assess the risk of explosion and take necessary precautions. Being aware of this threshold allows mine rescue teams to effectively prepare and respond to potential methane-related emergencies, emphasizing the importance of maintaining Methane levels below the LEL to ensure the safety of all workers in the mine environment.
