This rule applies to everyone on our worksites, regardless of whether they work for us or not, and in real-terms it means that we:

  • ensure that any stored energy has been discharged and all energy sources have been isolated before starting work,
  • only perform energy isolation activities if we are trained and competent to do so,
  • isolate all energy sources by placing locks and tags at agreed isolation points,
  • test and continually monitor the effectiveness of our energy isolations,
  • never remove any locks or tags unless we are authorised to do so,
  • never begin 'live work' on an energised system until we have:
  1. completed a risk assessment,
  2. implemented suitable controls,
  3. developed an emergency rescue plan, and
  4. obtained written authorisation.
