Hydrogen Sulfide (H2S) Awareness

Awareness training for anyone who works on or visits a site where hydrogen sulfide may be present: drilling, well servicing and production crews, gas plant and refinery workers, tank and vacuum truck drivers, wastewater and sewer workers, and their supervisors. It covers what the gas is, how it harms, where exposure happens, detection, site controls, breathing apparatus at knowledge level, and what to do in an alarm. It is not an accredited hydrogen sulfide certificate (such as a course to ANSI/ASSP Z390.1, an OPITO course or H2S Alive), awards none, and does not qualify anyone to wear breathing apparatus or to rescue; that practice is done in person.

Very informative course. Clearly explained H2S dangers, wind direction, and why never to attempt rescue without proper BA and backup. Highly recommended for anyone working in oil & gas.
