The Health and Safety Executive (HSE) has issued a reminder to construction companies of their legal obligations to prevent unauthorised access to sites ahead of the school holiday period. Under Regulations 13(4), 15(10) and 4(6) of the Construction (Design and Management) Regulations 2015, SI 2015/51, those in control of sites must erect and maintain perimeter fencing, secure sites outside working hours, cover excavations, immobilise plant and vehicles and lock away hazardous substances. The HSE has directed firms to guidance documents HSG 151 and CIS72 for further detail on managing risks and protecting the public.
