Use

Materials

  • If it sticks to a magnet it is fine.
  • If it is stainless (and you are sure) it is fine.
  • Otherwise check first.

Before Use

  • Ensure that the wheels are free from defects and have no aluminium embedded in them. They should be dull, not shiny.
  • Ensure that the rests are near but not touching the wheels.
  • Ensure that the guards are down - adjust them from the hinge not the loose end.

Using the grinder

  • Do not grip the work too close to the wheel - it gets hot
  • Do not force the work too hard
  • When smoothing the end of a rod, steady it with one hand and turn it with another

Safety

  • Wear eye protection - hot metal in the eye is not pleasant
  • Do NOT wear gloves - they could get entangled and pull your hand into the machine
  • Never use the side of the wheel, however convenient it may seem. This can cause the wheel to shatter.

Additional Notes

Any member who wishes to use the equipment must be trained in its safe operation by a competent member or other body, 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
