What the law says
- Under the law, trespassers have the right to expect not to be put at risk if they enter a construction site, particularly children who are less aware of danger.
- The CDM Regulations place a specific duty on the Principal Contractor to ensure unauthorised persons do not gain access to the site.
Some risks to the unwary
- Children often find that construction sites are exciting places to play – ensure they cannot gain access after normal working hours.
- Power tools, plant and equipment may be too tempting if not disabled or locked away; they could be stolen or cause injury to the inexperienced.
- Hazardous substances which you may be familiar with and use daily may cause serious injury to unauthorised persons; lock them away when not in use.
- Ensure that an effective system of access control is operated.
- Remove ladders from scaffolds or securely board up the lower rungs to prevent access at the end of each working day.
- Check that the perimeter hoarding or fencing is intact and is to a standard which does not encourage unauthorised entry.
- Remove keys from view and secure any tools, equipment and materials which might tempt thieves on to the site after normal working hours.
Dealing with trespassers
- Ask suspected trespasses who they wish to see and, if necessary, escort them to site security. If they are genuine visitors, the will not mind being challenged.
- Ensure that trespassing children are escorted off the site immediately.
- Do not put yourself in a position where you could be accused of assault.
