Is your detector calibrated?

1. Is your detector calibrated? In confined spaces—manholes, tanks, silos, crawl spaces—danger doesn’t announce itself. It waits silently in the form of toxic gases, oxygen-deficient environments, or explosive atmospheres. That’s why every confined space entry begins with one critical step: checking the air with a portable gas detector. But here’s a question too few ask: Is your detector calibrated? A portable gas detector that hasn’t been properly calibrated is like a smoke alarm with dead batteries. It might chirp, blink, and look like it’s working—but when danger hits, it won’t protect you. Calibration ensures the sensors are accurately measuring gas concentrations and triggering alarms at the correct levels. Without it, readings are guesswork—and in confined spaces, guesswork is deadly. Routine Portable Gas Detector Calibration is a safety must. Bump tests should be performed before each use, and full calibrations should follow manufacturer guidelines or regulatory requirements. If your team skips this step, they’re walking blind into some of the most dangerous work environments on earth. But calibration alone isn’t enough. Workers must understand how to properly enter a confined space, read detector data, use ventilation systems, and prepare for rescue

2. scenarios. The combination of a well-calibrated tool and a well-trained operator can mean the difference between a routine task and a tragic outcome. And that’s where expert training comes in. Gas Monitor Competence Training provides hands-on, real-world instruction in gas detector calibration and Confined space entry safety. They equip workers with the knowledge to trust their tools—and themselves—when it matters most. If safety is your priority, training should be your standard.
