Exposure of workers to hydrogen sulphide gas
This safety alert is for NSW workplaces which may use, generate, store or handle hydrogen sulphide (H2S) gas. It will help them to identify sources of potential exposure and manage risks to health and safety. This is especially important for work in, on or near confined spaces such as tanks, pits, sumps, vessels as well as partially enclosed areas with poor ventilation. Hydrogen sulphide can be produced unintentionally.
