When you’re working with flammable, toxic, or explosive gases, having the right equipment isn’t just a precaution; it’s a necessity. And even if you’re not working in oil and gas or chemical manufacturing, industrial environments frequently feature hazardous gases that can pose serious health and safety risks.

One of the most important pieces of equipment for monitoring hazardous gases is the portable gas monitor. Carbon dioxide detectors are essential to protecting workers, ensuring compliance with regulations, and maintaining productivity in hazardous environments.

Monitoring Hazardous Gases: Tools and Best Practices

Before you purchase a portable gas monitor, it’s important to know what types of gases you will be monitoring. Specifically, you should select a device that can detect both oxygen and combustible gases, as well as potentially toxic vapors. The device should also have ATEX certification (if applicable in your area) if you will be using it in an explosive environment, and it should contain an oxygen sensor to alert for both oxygen enrichment or depletion. Combustible gas detectors should alert the user when combustible concentrations exceed pre-configured levels, and they should also include an LEL (Lower Explosive Limit) sensor to warn users when dangerous levels of flammable gases are detected.

Choosing a location for the sensor can be challenging, as you need to consider how a leaking gas will disperse into the space. The sensor should be placed near the most probable source of a leak, but it is crucial to maintain coverage of the entire protected volume. Additionally, it’s important to consider the impact of temperature on the behavior of the leaking gas. Many heavier-than-air gases will be delayed in reaching the sensor due to a thermal barrier, while lighter-than-air gases can be warmed by the ambient air density and disperse rapidly.
