Why use a methane gas detector?

Methane gas (CH4) is a chemical compound made up of 1 carbon atom and 4 hydrogen atoms. It is the main component of natural gas and therefore is commonly used for fuel. In the environment it is found underground and below the sea floor where it is slowly released into the atmosphere. Although it is not toxic it is extremely flammable and can form explosive mixtures with air.

Natural Gas

Methane gas is sourced from the extraction of geological deposits. It is very important in electrical generation via burning  of the gas as a fuel. In many cities it is also piped directly into homes and used for heating and cooking. When released into the atmosphere methane gas is dispersed rapidly as it is lighter than air. However, in poorly ventilated sites it is important to ensure the concentration does not exceed safe levels. Methane displaces oxygen which could lead to asphyxia if leaks occur. Aeroqual can provide a portable and fixed methane gas detector suitable for leak detection.

Landfill Off-Gas

The most common source of methane exposure is around landfill sites. Methane gas is produced naturally via a process called methanogenesis which is a form of anaerobic respiration used by organisms found at landfills. This process also occurs in ruminants, such as cattle, and therefore methane concentrations can also be higher at cattle farms.  Landfill off-gas can penetrate the interiors of buildings built on or near landfills. Monitoring at landfills and the surrounding locations is important to avoid suffocation or uncontrolled explosions. Aeroqual have a range of portable methane gas monitors suitable for this application.
