You should manage risks by working through the hierarchy of control measures.

The hierarchy of controls requires that you first aim to eliminate a risk. For example, if there is a risk of a contact with overhead electrical lines, use a line pump instead of a boom pump.

* Substitute the hazard for something safer. For example, when core filling block work, provide a working platform next to the wall instead of having the line hand walk along the top of the wall.

* Isolate the risk from workers. For example, use exclusion zones to minimise risk of crushing or trapping workers when moving the pump to work in different positions, and use engineering controls such as fitting vehicles with reversing sensors and cameras.

* Personal protective equipment (PPE) should be used to control any remaining risks.

* Placing concrete, (work to avoid hose whip, set exclusion zones).

* Manual handling, (rotate workers on repetitive tasks, ensure adequate number of workers to perform task)

* Wet concrete, (have clean water available for washing skin, provide appropriate PPE, such as gloves, safety goggles, hard hat and waterproof footwear.

* Overhead power lines, consider use of a line pump.
