Gas Detection Evolution: From Canaries to Portable Real-Time Devices

Working in confined spaces present three kinds of hazards: flammable or explosive atmosphere; oxygen-deficient or oxygen-enriched atmosphere; and atmosphere with a high concentration of contaminants. In poorly ventilated spaces, atmospheric contaminants build up to hazardous levels very fast and pose an immediate threat to life. To eliminate potential dangers while working in underground mines, … read more
