New TLV® exposure limit: Measuring hydrogen sulfide

By Robert Henderson
No Comments
In the past, the most widely recognized occupational exposure limits for hydrogen sulfide (H2S) have referenced an 8-hour TWA of 10 ppm, and a 15-minute STEL of 15 ppm. In February 2010, the American Conference of Governmental Industrial Hygienists (ACGIH®) adopted a new threshold limit value (TLV®) recommendation for H2S, lowering the 8-hour TWA to 1.0 ppm, and the STEL to 5.0 ppm.

Docking stations: Let automation take the pain out of calibration

By Robert Henderson
No Comments
In the world of gas detection instrumentation, the expression “better safe than sorry” certainly holds true. Manufacturers and regulatory agencies agree the safest and most conservative approach to assuring instrumentation accuracy is to perform a functional test by exposing the instrument to known concentration test gas before each day’s use.
