2019-4-22 · Sulfur dioxide effects on health. Sulfur dioxide (SO2) is a colorless gas with a pungent fragrance that may cause breathing system and eyes irritation starting at 1 ppm!Even if it is corrosive and harmful, this gas is above all toxic.It has been classified as R23 (toxic by inhalation) and R34 (causes burns). Lastly, sulfur dioxide is very reactive with many solvents (alcohol, toluene), and

ClO2 gas detector, Chlorine dioxide - GazDetect

2019-4-22 · Despite its color and irritating smell, only a ClO2 gas detector can accurately measure chlorine dioxide gas concentrations. Moreover, even if this gas is explosive at 5.1% volume, an explosive capacity LEL monitoring would be useless with this highly toxic gas. It is thus recommended to use a ppm or ppb chlorine dioxide detection equipment.
