What it contains

Every year, people are seriously injured or killed when they come into contact with moving parts of machinery or equipment (plant) while conducting maintenance or non-production activities. These accidents can be reduced or eliminated through the correct process of isolating, locking out and tagging. This document tells you:

  • the range of machinery and equipment covered by the term ‘plant’
  • what an isolation procedure is
  • who you should consult to develop isolation procedures
  • how to isolate plant
  • what to do if it is not practicable to isolate plant
  • how to identify all energy sources and other hazards
  • how to identify all isolation points and energy sources in a system
  • how to de-energise plant
  • how to lock out all isolation points
  • how to test your isolation procedures
  • your legal requirements
