You are the health and safety officer for a manufacturing company. The company makes steel buttons and has seven button making machines that operate electronically in each of the 5 worksites across the state. Each workshop area is a tight-nit group of men who like to compete with the other workshops on a monthly basis to improve production. This competitive nature often leads to shortcuts being taken and small issues with the machines not being communicated to management.

You have just completed a safety inspection and are walking back to your office thinking about how you will speak to the manager of the workshop regarding the poor state of the machines when you hear a scream coming from the workshop floor. You run back to the workshop and you see a worker lying on the floor in front of machine 3. The worker has blood all around his hands. You notice that the worker has lost two fingers and the machine is making a noise that sounds like it has become stuck, and the power is still being supplied.

Identify who you would suggest being in the investigation team and why you are including them? And Why?
