Summary
Hazard alert addressing sudden pressure releases during commissioning, decommissioning, maintenance and repair in the oil and gas industry. It identifies equipment integrity problems, changing conditions and unsafe work practices, and outlines employer and worker responsibilities for assessments, isolation, controlled depressurisation, safe procedures and avoiding released-energy paths.
