4 gas monitors are used extensively in many industrial and scientific applications but can be hazardous if concentrations exceed safe limits. Inert gases such as argon, nitrogen and helium are widely used in additive manufacturing (AM) machines, solder reflow ovens and gloveboxes to safeguard combustible or perishable products from unwanted reactions by replacing oxygen with non-reactive gases. Regular monitoring ensures that gas levels remain within safe limits to prevent oxidation and asphyxiation.
Inert Gas Analyzers: Their Role in Workplace Safety
Inert atmospheres are also required for transporting flammable cargo in oil tankers, in catalytic processes such as those carried out in refinery catalyst maintenance and welding operations to maintain oxygen levels below the combustion or explosion limit of the compounds being processed. In these cases it is critical to monitor the atmosphere with an oxygen and/or carbon monoxide detector.
If an oxygen deficiency sensor detects a loss of inert gas, it can alert personnel to evacuate the area before the concentration of oxygen drops to unsafe levels. This simple measure can save lives, and reduce property damage and business disruption. Gas analyzers with audio and visual alarms can help ensure a safe work environment by providing early warning of dangerous conditions. These devices allow personnel to take prompt actions such as evacuation, shutting down equipment and taking control measures to limit leaks and fires. They also provide data to optimise the usage of inert gas blanketing systems, cutting costs and saving energy consumption. This can reduce environmental footprint and product waste.
