Understanding Risk Rating:
| Risk Rating | Action |
| LOW | Ensure current control measures are in place and continue with activity |
| MED | Control measures may be adequate, co-supervision is recommended |
| HIGH | Do not undertake activity without further consultation with area specialists |
Risk Assessment
| Identify Hazards | Who may be harmed and how | Severity | Control Measures | Likelihood | Risk Rating |
| Something with the potential to cause harm | Users, bystanders or particular at risk groups | Low / Medium / High | What is in place to reduce the harm or likelihood. | Low / Medium / High | |
| Incompetent user | User, Bystander | HIGH | Users must not use tools that they are not competent to use. Members must challenge use that they believe is dangerous. All members wishing to use the mill must request training for tool via the members area Users must read the risk assessment before using a tool. Users must complete induction before use. | LOW | MED |
| Contact with cutter | User | HIGH | Do not touch moving parts of machine once in use Do not put hands behind the guard – If swarf removal is needed use a brush Mill should be switched off immediately after use Do Not Wear Gloves or loose clothing when operating the machine Tie long hair back when operating the machine | LOW | MED |
| Ejection of workpiece (Kickback) | User of the tool, users of the room, the space. | HIGH | Use a machine vice where possible. Make sure the part is secured in the vice or to the table before starting a cut Cuts should not exceed recommended cutting depth or feed. Parts attached directly to the bed must be securely clamped The vice or other workholding jigs must be attached securely to the bed Other users of the room should not be close to the machine The machine should be used with it’s guard attached, when possible Support for parts, in the form of parallels, centres, jacks, etc, should be used where appropriate. | LOW | MED |
| Cutter snatching or jamming | User of the tool, users of the room, the space. | LOW | Do not exceed the recommended feed and speed settings of the mill Do not exceed recommended cutting depths Make sure that your material is free from foreign objects. Do not make a cut that exceeds your material depth. Ensure cutter is sharp before use Side-cutting tools are not to be held in a Jacobs chuck. The machine should be used with it’s guard attached, when possible | MED | LOW |
| Noise | User of the tool, users of the room. | LOW | Ear protection is advised, particularly on harder materials | LOW | LOW |
| Flying splinters of broken cutter | User of the tool, users of the room. | MED | Eye protection must be worn whilst using the mill Eye protection must be worn by all users of the workshop. Do not exceed the recommended feed and speed settings on the mill Do not exceed recommended cutting depths Make sure that your material is free from foreign objects. Do not make a cut that exceeds your material depth. Ensure cutters are sharp before use Ensure the drawbar is tight before starting the machine The machine should be used with it’s guard attached, when possible | MED | MED |
| Hot, sharp, swarf | User of the tool, users of the room. | MED | Eye protection must be worn whilst using the mill Eye protection must be worn by all users of the workshop. Swarf should not be removed by hand – use a brush or vacuum Swarf should be cleared into a metal bin after use after the mill has been used The machine should be used with it’s guard attached, when possible | MED | MED |
| Drawbar – spinning and ejecting spanner | User of the tool, users of the room, the machine itself | HIGH | Drawbar cap must be over the drawbar when the machine is on The spanner to remove or tighten the drawbar must be removed before the machine is turned on The drawbar must be tightened for any tool that is to spin under power | LOW | MED |
| Chuck keys and collet spanners – ejected | User of the tool, users of the room, the machine | HIGH | Chuck keys and spanners must be removed from the chuck before starting the spindle. The guard should be used where possible | LOW | MED |
| Tooling coming loose and coming out | User of the tool, users of the room, the machine | MED | Ensure the drawbar is tight before using the machine If a collet chuck is used, ensure the correct collet is used, and the collet is holding the tool securely | MED | MED |
| Electrical – Damage to cables or internal electronics | User of the tool | MED | The mains cable should not be exposed to the spindle side of the machine The machine must not be used with a damaged mains cable The machine should be PAT tested at reasonable intervals – at least once per year All users must be made aware of the location of the emergency stop | MED | MED |
| Driving the tool holder into the vice or part with Z-axis power feed | The machine, user of the tool | LOW | The user of the machine must be warned to leave some space when machining with the power feed If the spindle crashes into the workpiece, the mill should be turned off and the quill feed disengaged. | MED | LOW |
| Tripping over debris around the mil | The user of the tool | MED | No items are to be left within the purple line. A user must remove any items from the purple line before using the mill. | MED | MED |
