A proposed ASTM International standard will protect worker’s health by monitoring the levels of hydrogen sulfide gas in workplace air.
The proposed standard (WK59402, Test Methods for Measurement of Hydrogen Sulfide in Workplace Air by Direct-Reading Electrochemical Detectors) is being developed by the ASTM International committee on air quality (D22).
The proposed standard will use direct-reading electrochemical detectors to identify whether the concentration of hydrogen sulfide gas exceeds the maximum allowable concentration (MAC) or other limits.
Occupational health protection agencies, regulatory bodies, and technical service organizations will find this standard useful because it will help identify air quality at the job site.
