The Health & Safety at Work etc. Act 1974 requires us to do what is 'reasonably practicable' to ensure our health and safety at work, and the health and safety of colleagues and others, for example students, who may be affected by our work activities. Case law has shown that in order to do what is 'reasonably practicable', an assessment of risk must be undertaken and measures to reduce risks to an acceptable level implemented. In addition, Regulation 3 of The Management of Health & Safety at Work Regulations 1999 explicitly requires risk assessment to be undertaken.
