Hydrogen sulphide (H2S) is a colourless gas that is harmless in small quantities, but is often regarded as an annoyance due to its distinctive rotten-egg smell. Anthropogenic (man-made) sources of hydrogen sulphide account for approximately 5 percent of total hydrogen sulphide emissions. H2S emissions vary with type and size of the plant and with the chemical quality of the resource.
During drilling and certain plant maintenance activities at some reservoirs, hydrogen sulphide gases can pose a worker safety issue. Appropriate plant design and drilling safety procedures developed through oil and gas and geothermal experience are therefore implemented, and standards and procedures are imposed by state and federal regulatory agencies. In addition, H2S is abated at some geothermal power plants where necessary to meet air quality standards. The two most commonly used vent gas hydrogen sulphide abatement systems are the Stretford and LO-CAT. Both systems convert over 99.9 per cent of the hydrogen sulphide from geothermal non-condensable gases to elemental sulphur, which can then be used as a soil amendment and fertiliser feedstock. The cost to transport and sell the sulphur as a soil amendment is about equal to the revenue gained from the transaction.
H2S Course Overview
Intended for individuals who may be exposed to hydrogen sulphide in the workplace, Southbrook Safety offers a comprehensive on-line course providing information to help protect individuals from exposure and explains how to deal with emergencies involving H2S.

H2S On-line Test
Testing conducted throughout this online H2S course is designed to reinforce the information presented. A mark of 80% must be achieved in order to receive a certificate of completion. Participants are able to repeat the course twice if the pass mark is not achieved on the first attempt.
H2S On-line Certificate of Completion
Upon successful completion of this online course, a certificate of completion will be available to download and print. The certificate is valid for three (3) years.
Cross-Platform Compatible
This course was created using standards that will allow playback on most internet capable devices with standard web browsing capabilities including Apple’s iTouch, iPad, and iPhone, as well as most other smartphones and tablets including those with Android and Windows operating systems.
