Health & Safety Risk Management System

S17 - Isolation & Lock off

Stored energy whether it be electrical, pneumatic, hydraulic or gravitational can cause equipment to move or pipes to burst. A system for controlling that energy is an essential measure to reduce risk when maintenance is being undertaken.

Ensuring that people are aware of where to isolate and having a process for them to prove that the isolation is effective will remove the risk of contact with moving machinery, pressurised air and oil injuries.

This procedure gives guidance on an isolation and lock off system. It includes templates for a site-specific procedure and a list of isolators and the items of equipment they isolate.
