Construction sites are highly vulnerable to fire. The JCOP provides the framework for protecting sites during construction, but compliance is often inadequate.. Construction Site Fire Risk Fire during construction can destroy entire developments and cause fatalities. The Joint Code of Practice on the Protection from Fire of Construction Sites and Buildings Undergoing Renovation (JCOP) provides comprehensive guidance. Why Construction Sites Are Vulnerable Exposed structural elements (timber frame, structural steel) Hot works (welding, cutting, soldering) Temporary electrical installations Combustible waste accumulation Limited or no fire detection and suppression Multiple contractors with varying safety standards Arson — construction sites are targets for deliberate fire setting JCOP Key Requirements Fire Risk Assessment: Must be completed before works commence Updated at each construction phase Consider changing fire risks as building progresses Specific assessment for hot works Hot Works Permit System: Written permit for all hot works Designated hot works supervisor Fire watch for minimum 60 minutes after hot works cease Fire extinguisher within 10m of hot works location Combustible materials cleared from work area Site Security: Perimeter fencing and access control CCTV with thermal imaging capability Security patrols outside working hours Secure storage of flammable materials Temporary Fire Protection: Progressive installation of permanent fire protection Temporary fire alarm system during construction Fire extinguishers at each level of the building Temporary emergency lighting on escape routes The Insurance Perspective Insurers are increasingly requiring: Compliance with JCOP as a policy condition Independent fire safety audits during construction Specific timber frame fire safety plans 24/7 fire watch on high risk sites Recent Major Construction Fires Multiple UK apartment block fires during construction phase Total losses frequently exceeding £50 million Most caused by hot works or arson Insurance industry tightening requirements in response For construction phase fire safety, contact us.
