to carry out work at heights by replacing manual twist locks with automatic twist locks.
         If elimination is not reasonably practicable, you must minimise the risk by following the control measures in the hierarchy below.
Level 2  Substitution – substitute the work practice or equipment with something safer. For example, substitute a hazardous chemical with a less hazardous chemical.
         Isolation – physically separate the source of harm from people by distance or by using barriers. For example, use physical barriers to separate pedestrians from mobile plant.
         Engineering controls – are physical control measures including mechanical devices or processes. For example, install guards on conveyor systems or speed limiters on forklifts.
Level 3  Administrative controls – if a risk remains, it must be minimised with administrative controls like training workers to use safe work procedures, using warning signs or arranging work to minimise the time spent near noisy machinery.
         PPE – any remaining risk must be minimised with suitable PPE, for example by providing workers with high visibility clothing, gloves, non-slip footwear, and hearing and eye protection.

Administrative control measures and PPE do not control the hazard at the source. They rely on human behaviour and should only be used:
       when there are no other practical control measures available—so as a last resort
       as an interim measure until a more effective way of controlling the risk can be used, and
       to supplement higher level control measures—as a back-up.
In many cases a combination of control measures provides the best solution.
When selecting and implementing a combination of control measures it is important to consider whether new risks might be introduced as a result and, if so, whether the combination of the control measures should be reviewed.

    2.4           Maintaining and reviewing control measures

WHS Regulations
Regulation 37: Control measures must be maintained so that they continue to protect workers and other people from the hazards associated with plant. The control measures must be:
       fit for purpose
       suitable for the nature and duration of the work, and
       installed, set up and used correctly.
Regulation 38: A PCBU must review and as necessary revise control measures:
       when the control measure is not effective in controlling the risk
       before a change at the workplace that is likely to give rise to a new or different health and safety risk that the control measure may not effectively control
       if a new hazard or risk is identified
       if the results of consultation indicate that a review is necessary, and
       if a health and safety representative requests a review.
Reviewing the hazard and the risk controls is an important part of the risk management process. The aim
