In case of an accidental release, activate your facility’s leak response plan, if available. Evacuate non‐essential personnel and secure all ignition sources. WebHence, when the volume percentage of methane in an environment falls between 5% to 17%, the environmental condition is highly hazardous. The range of 5% to 17% is the explosive range for methane gas. When the volume percentage of methane is below 5% or above 17%, there will not be an explosion.
