This practice covers the detection of hydrogen sulfide gas in workplace air by direct-reading electrochemical detectors. This standard aims to protect the workers health and safety when they are working by monitoring whether the concentration of hydrogen sulfide gas exceeds the maximum allowable concentration (MAC) or other limits. The direct-reading gases detectors using electrochemical sensor are included. The sample results are immediately available by visual observation, thus no follow-up analytical equipment is needed.
hydrogen sulfide; electrochemical detector
Hydrogen sulfide is a very common occupational disease and harmful factor, which is widely distributed in the air of various workplaces in oil extraction, petrochemical and other industries. Therefore, the accurate detection of hydrogen sulfide is an important premise to protect the safety and health of workers.
