1. Have a competent person carry out a risk assessment of the machine;

• The Defendant should have ensured that a person competent in machine safety carried out a risk assessment of the machine to ensure that all dangerous aspects were adequately identified and managed.

2. Identify the entanglement hazard that the rotating mechanical stirrer on the machine presented;

3. Adequately guard the machine to isolate workers from the rotating mechanical stirrer;

• The Defendant should have had either a fixed or interlocked guard over the top of the hopper to ensure that they could not access the moving parts 

4. Develop a safe system of work for the operation of the machine including a procedure for scraping the sides of the hopper;

• Operating procedures and training documentation should have clearly set out how the hopper was to be scraped safely, including the need to lockout energy sources.
• If the Defendant’s intention was that the hopper wasn’t to be scraped down by workers, workers should have been clearly informed of this and also of the process to follow when product was running low.
