Hazard Type Description of Hazard Initial Risk Action Required Final Risk
Severity Probability Rating Severity Probability Rating
Trap risk Body parts getting trapped in moving belts, or entanglement of hair or clothing in moving machinery 3 2 6 Don't touch the machine when it is in operation. Even when it appears inactive it might just be waiting for temperatures to stabilise, etc., so ensure it is actually stopped before touching it. 3 1 3
Burns Burns from touching extruder head, heated base plate or hot plastic extrusions 2 3 6 Don't touch extruder head or base plate when they are hot or extruded plastic until it has cooled 2 1 2
Fumes Toxic fumes if feed material is over-heated 2 3 6 Only print materials suitable for melting / 3D printing, e.g. PLA or ABS. If you're not certain that a material is safe to melt, check with a competent member first. 2 1 2

Additional Notes

Any member who wishes to use the equipment must be trained in its safe operation by the 3D printer team, and supervised until competent. The findings of this risk assessment should be explained to the member. Any hazards discovered during use of the equipment should be investigated and this Risk Assessment updated if necessary.

Guide to the risk matrix points system

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 probability 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 Definitions
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
