Debris and poorly stored materials on construction sites are a leading cause of trips, slips, and blocked access.
The Workplace (Health, Safety and Welfare) Regulations 1992 require work areas to be kept clean and orderly.
Common obstructions include offcuts, packaging, surplus materials, damaged goods, and general construction waste.
Blocked access routes prevent emergency evacuation and delay rescue in the event of a site incident.
Materials stored on walkways force workers to take detours or climb over obstacles, increasing injury risk.
Fire escape routes must be kept clear at all times — blocking them is a serious breach of fire safety law.
Poor housekeeping also attracts vermin, creates fire loading, and gives an unprofessional site appearance.
Designated storage areas, skip positioning, and regular clean-ups prevent debris accumulation.
CDM 2015 requires the principal contractor to ensure good order and housekeeping across the site.
Daily housekeeping inspections should identify and remove obstructions before they cause incidents.

Prevent trips and falls	Debris on walkways and in work areas is the most common cause of trip injuries on construction sites.
Emergency access	Blocked routes prevent evacuation and rescue — this can turn a minor incident into a fatality.
Legal duty	The Workplace Regulations 1992, CDM 2015, and the Fire Safety Order require clear, orderly work areas.

Don't

Clear your work area of debris and offcuts at the end of every task and shift
Store materials in designated areas away from walkways, access routes, and fire exits
Position skips and waste containers close to work areas to encourage regular disposal
Carry out daily housekeeping inspections and address obstructions before work starts
Keep emergency escape routes and fire exits clear of all materials and equipment
Use designated material storage zones with clear labelling and stacking limits
Brief all trades on their responsibility to maintain housekeeping in shared work areas
Arrange regular waste collections so skips and bins do not overflow onto walkways
Report blocked access routes or obstructed fire exits to the supervisor immediately
Include housekeeping standards as a standing item in daily briefings and inspections

DON'T leave offcuts, packaging, or waste materials on walkways or in access routes
DON'T block fire escape routes with stored materials, plant, or construction waste
DON'T stack materials higher than the designated limit or beyond the storage zone boundary
DON'T assume someone else will clean up debris from your work area at the end of shift
DON'T allow waste to accumulate to the point where it creates a fire loading hazard
DON'T store materials on stairways, landings, or in front of emergency equipment
DON'T climb over obstructions instead of clearing them or finding a safe alternative route
DON'T leave protruding nails, screws, or sharp edges in discarded timber or materials
DON'T ignore poor housekeeping by other trades — raise it with the site supervisor
DON'T treat housekeeping as a low priority — it prevents the most common site injuries
