D.2 Checklist: Electrical Equipment, Machines and Power
tools
This checklist has been developed to provide guidance on safe work practices. It should help in a
stone crushing unit to assess specific jobs and see if they pose a risk to health of the workers. Not all
of these questions apply to all workplaces. To calculate the correct score you need to exclude the
topics, which are not applicable. It is limited to questions that can be easily answered by observation
and questioning the workers. It is therefore not all inclusive in coverage. Answers that do not comply
with the preset ones () indicate problem areas, which should receive further attention. Further
investigation may be required to assess risks and make a decision on whether corrective measures are
required.
