Falls from height remain the leading cause of fatal injuries on UK construction sites. Any work where a person could fall a distance likely to cause injury is classified as work at height under the regulations. This includes work on roofs, scaffolds, ladders, and near unprotected edges. Every operative must understand the risks and follow the hierarchy of control measures to prevent serious injury or death.
Key Hazards
Fatal or life-changing injuries from falling even short distances
Unprotected edges, floor openings, and fragile surfaces
Failure of poorly maintained or incorrectly used access equipment
Falling objects striking workers at lower levels below
Control Measures
Avoid work at height wherever possible by planning tasks at ground level first.
Use collective protection such as guardrails, edge protection, and safety netting before personal measures.
Ensure all work at height is planned, supervised, and carried out by competent persons.
Inspect all access equipment before each use and report defects immediately to your supervisor.
Secure all floor openings and voids with fixed covers or guardrails clearly marked as hazards.
Use harnesses and lanyards only as a last resort, and only when trained in their correct use.
Check weather conditions before starting height work and stop if wind or rain makes it unsafe.
Keep work platforms clear of loose materials, tools, and tripping hazards at all times.
Use toe boards and brick guards to prevent materials falling onto people below.
Establish exclusion zones beneath all overhead work areas and control access strictly.
Emergency / Rescue
If someone falls from height, call 999 immediately. Do not move the casualty unless in further danger. Keep them warm and still until paramedics arrive. Activate the site emergency plan.
Remember
Falls from height are the biggest killer on UK construction sites every year.
Always follow the hierarchy: avoid, prevent, then minimise the distance of any fall.
Never work at height without proper training, planning, and the right equipment.
Report any missing edge protection, covers, or guardrails before starting your task.
Check your equipment every single time before you use it at height.
If conditions change and it feels unsafe, stop work and speak to your supervisor.
