Analox Sensor Technology is calling for increased awareness of the potential dangers to anyone whose job requires them to work in confined spaces. Analox Sensor Technology specializes in gas sensors, detectors and alarms. “It is easy for oxygen levels to fall in confined spaces, or levels of toxic gases to rise,” said Managing Director Mark Lewis. “Without detection equipment, a person cannot know before entering such a space whether it is safe or not. The call for better awareness of the potential dangers follows an incident in which a water meter reader suffered severe brain damage. It was reported by IMCA, the International Marine Contractors Association. The meter reader entered a chamber approximately 1.8 meters deep to carry out a routine reading.
