A sample of risk assessments for one or more of the following high hazard activities may be requested from departments who are undergoing a Target 100 (T100) assessment. Departments will have other risk assessments but if they work with hazards that are associated with the listed topic it will be a sample of these that will be requested for scrutiny as evidence for the following T100 measure:
'Written risk assessments are available for a sample of work activities that have significant hazards'
