This information sheet provides guidance for duty holders on detecting and managing hydrogen sulphide (H2S) hazards in hydrocarbon processing systems. As reservoirs begin to water out, hydrogen sulphide can become an issue when processing returning fluids. The gas is toxic in relatively low concentrations and the risks to the workforce need to be addressed as soon as its’ presence becomes known. It is not intended to provide detailed advice on workplace exposure limits, which are detailed in EH401.
