Team 3D/Risk Assessment
This page contains the risk assessment for all printer operations; all printers should be assumed to fall into the generic form of their print type if not individually specified. This is to prevent copypasting for each individual machine, and to encourage thourough evaluation when needed. Typically the generic printer case should cover all or exceed the risks of any given printer.
Please see Points system for the details
Note: This covers NORMAL OPERATION. Scope of this is defined per assessment, but this means it covers things like printing, and not doing maintainence
FFF
Covers FFF, Fused Filament Fabrication (also known as FDM (Fused Deposition Modeling)) machines
If a machine uses filament, it is in here
Generic
Notice: this is currently a work in progress
Scope
This assessment covers:
- Printing with the printer
- Controlling the printer from the LCD
- Controlling the printer via in hackspace web interfaces
- Changing filament
- Removing prints when finished
Hazards
- Hotend - Heated component
- Heated Bed - Heated component
Persons at risk
- Operator
Initial assessment of risk
| Hazard identified | Severity | Probability | Risk Factor |
| Hotend | 2 | 1 | 2 |
| Heated Bed | 2 | 1 | 2 |

Points system
This is the standard points system used for all Risk assessments on the wiki thus far. It was copied in for completeness
| Hazard severity | Points Rating | Definition |
| Nil | 1 | Very minor injury, bruise, graze, no risk of disease. |
| Slight | 2 | Minor injury, which would allow the individual to continue work after first aid treatment on site or at a local surgery. The duration of the stoppage or treatment is such that the normal flow of work is not seriously interrupted. |
| Moderate | 3 | Temporary disability causing injury or disease capable of keeping an individual off work for three days or more and reportable under RIDDOR |
| High | 4 | Causing death, serious injury or permanent disability to an individual. |
| Very high | 5 | Causing multiple deaths and widespread destruction eg. fire, building collapse. |
| Hazard likelihood | Points Rating | Definition |
| Remote possibility | 1 | There is really no risk present. Only under freak conditions could there be any possibility of an accident or illness. All reasonable precautions have been taken - This should be the normal state of the workplace. |
| Unlikely | 2 | This incident or illness might occur but the probability is low and the risk minimal. |
| Possible | 3 | The accident may occur if additional factors precipitate it, but it is unlikely to happen without them. |
| Highly likely | 4 | Will happen more often than not. Additional factors could precipitate an incident but it is still likely to happen without this additional factor. |
| Inevitable | 5 | If the work continues as it is, there is almost 100% certainty that an accident will happen, for example:
A broken stair or broken rung on a ladder Bare, exposed electrical conductors Unstable stacks of heavy boxes |
| Risk Rating Score | Definition | Action |
| 1 to 4 | Low | No action required |
| 5 to 9 | Moderate | Reduce risks if reasonably practicable |
| 10 to 15 | High Risk | Priority action to be undertaken |
| 16 to 25 | Unacceptable | Action must be taken IMMEDIATELY |
