Methane can be an extremely dangerous gas, particularly in industrial and commercial environments. Unlike other gases, methane is odorless and thereby undetectable by smell. It’s also highly flammable and combustible with oxygen. As methane is a primary component of natural gas, it’s found readily in our natural environment and is applied across a wide range of different industries.
