In industrial safety, methane is a potentially hazardous gas. Because methane is colorless and odorless—and may not be odorized in many industrial environments—dangerous concentrations can accumulate without warning.

 

This is why portable methane detectors are widely used by personnel working in manholes, refineries, or along pipeline rights-of-way. It is a critical safety instrument for real-time gas monitoring and provides real-time digital monitoring of an invisible hazard, helping personnel identify potential gas accumulation promptly.

 

At RJM Company, we supply safety equipment designed to meet regulatory standards and protect workers in hazardous environments. Our tools are built for field personnel who need reliable equipment when entering confined spaces where air quality may be uncertain.

 

The Problem With "Fixed" Sensors

A lot of facilities rely on wall-mounted sensors. They have their place, but they have a major flaw: they’re stationary. Methane is lighter than air. It likes to rise and pool in ceiling corners, or it might be leaking from a specific flange thirty feet away from the nearest wall sensor. If you’re relying solely on fixed monitors, you’re operating with massive blind spots.

 

A portable methane detector moves with the worker, providing point-of-use monitoring. It can help detect small leaks and provide early warnings of potentially hazardous concentrations.

 

It allows your crew to assess a vault or tunnel with more direct readings, rather than relying solely on distant sensors.

 

Field Durability: Built for the Grime

Industrial sites can be challenging for electronics. Exposure to mud, heavy machinery vibrations, and the elements may reduce the effectiveness of consumer-grade devices.

 

If a tool is too delicate or difficult to calibrate in the field, it may not be used consistently or effectively.

 

We see these units being put to work in:

 

Utility Excavation: Checking for cross-bores or nicked lines during a dig.

 

Storage Tank Cleaning: Verifying that the atmosphere is "LFL-safe" before a crew goes inside.

 

Landfill Management: Tracking the migration of gas through the soil and into nearby structures.

 

Infrastructure Audits: Walking miles of pipeline to find fugitive emissions that are costing the company money and harming the environment.

Critical Safety Technology

When you’re looking at a portable methane detector, you have to look past the screen and into the sensor itself. Speed is everything. If the sensor response is delayed, a worker may be exposed to higher concentrations before an alarm is triggered. RJM’s hardware is designed for rapid response.

 

You need a device that offers high-sensitivity readings, usually displayed as a percentage of the Lower Explosive Limit (LEL). You also want something that logs that data. Modern safety programs encompass risk assessment, hazard mitigation, and continuous monitoring beyond traditional accident prevention. Maintaining a digital record helps document compliance with site-specific protocols. In the event of an audit or incident, these records provide valuable documentation.

​

Maintenance and Calibration: The Key to Reliability

A detector’s reliability depends on regular calibration. Because these sensors work in harsh environments, they are often subject to "sensor drift" over time. Dust, humidity, and extreme temperature swings can all nudge a sensor out of its peak accuracy range. This is why we emphasize simple, fast field calibration.

 

RJM’s units are designed so that a "bump test"—a quick check to ensure the sensors respond to a known concentration of gas—can be done in seconds before a shift starts. If the device fails the bump test, it should not be used until it passes calibration. Tools designed for easy calibration increase the likelihood that field personnel complete the process correctly and consistently.

 

Regular maintenance helps ensure that alarm signals more accurately reflect actual gas levels and reduce the likelihood of false positives caused by sensor drift or contamination.

​

Compliance and the Bottom Line

Safety is a critical aspect of risk management. Using a portable methane detector supports risk mitigation by helping protect personnel and reduce the potential costs associated with fire or regulatory violations.

 

Equipping crews with reliable, calibrated detection equipment can support a safer work culture. Workers gain confidence knowing that potential hazards are being monitored.

Taking Charge of the Site

Managing unseen risks is challenging. Using portable units provides additional monitoring, supporting more informed safety decisions in high-risk environments.

 

With RJM Company’s equipment, you gain accurate readings to support timely decisions. Portable detection complements fixed sensors and provides additional monitoring capability on-site.
