IECEx certifies modern gas detectors and sensors

A BBC News item dated 30 December 1986 announced that more than 200 canaries still employed in UK mines were to be made gradually redundant throughout 1987. The article stated that “new electronic detectors will replace the birds because they are said to be cheaper in the long run and more effective in indicating the presence of pollutants in the air otherwise unnoticed by miners.”
