Regulation 3 of the Management of Health & Safety at Work Regulations states that all employers shall “suitably and sufficiently” assess any risk to the health and of their employees while they are at work. It further states that employers with five or more employees must have written risk assessments.
A risk assessment will be reviewed should there be reason to suspect that it is valid no longer or there has been significant change in the matters to which it relates, a risk assessment shall be reviewed.
The regulations note that employers should not employ young persons unless, in relation to risks to the health and safety of young persons, they have made or reviewed an assessment.
