Businesses are reminded of their duty to identify hazards and manage risks to health and safety in accordance with the provisions of the Work Health and Safety Act 2011 and Work Health and Safety Regulation 2017.
Businesses must implement ‘reasonably practicable’ control measures to manage the risks associated with working on pressurised pipes, including:
- develop safe systems of work and apply isolation procedures that identify, lock out and tag out all energy sources while work or testing is being carried out. Where reasonably practicable provide engineering controls such as guards and removing workers from the area
- ensure end-caps are installed according to the manufacturer's specifications, including tightening fasteners to the specified torque using appropriate tools (eg calibrated manual torque wrench and correct size sockets)
- piping that is temporarily capped is to be fitted with a pressure gauge to identify any potential stored energy. Provide a vent valve or drain to release pressure prior to work commencing
- all inspections of associated pressure equipment are to be carried out by a competent person in accordance with the manufacturer’s recommendations.
