The CNC router does not require an induction, but you are expected to either have a good understanding of CNC, or be prepared to self study.

Risk	Existing Mitigations	Severity / Likelihood	Assessment	Action Required	Residual Risk
Electrical Shock due to damaged cabling or poor earthing.	Portable Appliance Testing (PAT) is performed according to a schedule. A visual inspection of the appliance should take place prior to use of the CNC router. RCDs are fitted.	5/1			1
Noise during cutting operations.	Ear defenders and single-use ear plugs are available near the CNC router and must be worn while operating the CNC.	3/5	The CNC user might not be aware how loud the equipment is.	Put up a hearing protection sign.	2
{{{risk_3}}}	{{{mitigation_3}}}	0/0			0
Injury due to the workpiece coming loose during routing.	An emergency stop button is located next to the CNC router. There are various options for clamping the workpiece to the CNC bed. These should be used in excess and if any movement is observed, the emergency stop button should be pressed.	5/3	The e-stop should be tested before cutting actually begins. The user might not be aware of the Superbox CNC Router advice.	Update wiki page to include this. Ensure a QR code for the wiki page is prominently displayed by the machine.	3
Injury due to sharp edges or swarf.	Ensure the router head has been moved away from the workpiece and use either compressed air or the vacuum cleaner to remove swarf.	2/4	The user might not be aware of how sharp edges may be.	Improve notes on the Superbox CNC Router page.	2
Injury due to flying chips.	Safety glasses are provided and must be worn.	4/3	The user might not be aware of this advice.	Display a safety glasses sign above the CNC.	2
