When do I need a young persons risk assessment?
Before a person under 18 starts work. The Management of Health and Safety at Work Regulations require a specific assessment that accounts for their inexperience, lack of awareness of risk and immaturity, and for under-16s the findings must be communicated to a parent or guardian.
Can apprentices use machinery?
Sometimes, with proper training and supervision, but certain high-risk work is restricted for under-18s. The assessment is where you record which activities are permitted, which are prohibited and what supervision applies — rather than deciding it informally on site.
Does this replace the general risk assessment?
No, it sits on top of it. The task still needs its own assessment; this one addresses whether that task is appropriate for this particular young person and what additional controls apply.
What happens when they turn 18?
The specific young-person duties fall away, but the assessment's review date is a good prompt to confirm the supervision arrangements are still right for someone who is still, in practice, inexperienced.
