The Health and Safety at Work Act 1974 requires employers to ensure the health and safety of all employees and anyone affected by their work, so far as is reasonably practicable, which means balancing the level of risk against the measures needed to control the risk in terms of money, time or trouble. This includes taking steps to control slip and trip risks.
The Management of Health & Safety at Work Regulations 1999 build on the HSWA to include a duty on employers to assess risks (including slip and trip risks) and take action where necessary.
