4 Gas Meter Gases Are Essential to Assess the Safety of Dangerous Spaces

Whether you work in sanitation, public works, oil refining or another industry where confined space entry is common, 4 gas meter gases are essential to assess the safety of these dangerous spaces before entering and continually monitor conditions during work. These meters can identify oxygen deficiency, toxic vapors and flammable gases that can be life-threatening to civilians and first responders alike.

What gases are used in gas monitoring?

Most multi-gas monitors detect the most toxic gases including hydrogen sulfide and carbon monoxide as well as the lower explosive limit (LEL) of flammable gasses such as propane, butane or methane. They can also measure the irritant gases such as ammonia or chlorine that may cause respiratory problems. The monitors can even measure the flammability of an atmosphere using a conversion chart that determines the LEL for the specific chemical in the air, usually expressed as %Vol.

A number of different models are available for a variety of workplaces and applications. Some confined space wall mount meters have built-in pumps that can take an ambient air sample from different depths and heights in the confined space. This can be especially useful when you need to sift for contaminated soil or other contaminants that have accumulated within the space.

Others are portable, wearable devices that can be used to test the air in a confined space before entering. The Marine 4, for example, has simple icons to indicate the status of oxygen, hydrogen sulfide, combustible and your choice of carbon monoxide or sulfur dioxide. It uses a long-life battery and can store readings for up to two months so you don’t have to worry about constantly monitoring and recharging your device.
