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 a soldering iron.	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			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			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			2
