COAL HANDLING SAFETY - AMETEK Land

2020-6-19  Carbon monoxide (CO) gas detection offers a fast, sensitive means to detect the presence of oxidising coal, as the oxidation process inevitably produces large amounts of CO and is a precursor to an actual fire. The most important reasons to choose CO measurement for these applications are the availability of very sensitive CO sensors

"Is Carbon Monoxide Sensing an Effective Early Fire ...

The ability of carbon monoxide (CO) sensing to detect early stage smouldering of fixed plant fires in underground coal mines was recently assessed as part of an ongoing fire detection research project. Experiments were carried out to record the level of CO concurrent at the time of alarm activation of a Video Based Fire Detection (VBFD) system.
