Temporary and permanent flood barriers are deployed to protect communities, infrastructure, and construction works from rising water levels. Installing and testing these barriers involves working near open water, handling heavy barrier sections, and operating under time pressure when flood warnings are issued. This talk covers the hazards and controls for safe flood barrier deployment and testing on site.
Key Hazards
Drowning from working near rising water levels during barrier deployment
Crushing injuries from heavy barrier sections during manual handling and placement
Barrier failure during testing causing uncontrolled water release into protected areas
Workers trapped by rapidly rising water if deployment takes longer than expected
Control Measures
Monitor water level forecasts and deploy barriers well ahead of predicted flood peaks.
Wear personal flotation devices when working near rising water during barrier installation.
Use mechanical lifting equipment to handle heavy barrier sections rather than manual methods.
Establish a clear evacuation procedure and trigger level for withdrawing the deployment team.
Test barrier seal integrity at low pressure before allowing water to build against the full system.
Brief the deployment team on the installation sequence, safety equipment, and withdrawal triggers.
Position rescue equipment including lifebuoys and throw lines at the deployment area.
Ensure adequate lighting for barrier deployment that may continue into darkness or overnight.
Record the deployment sequence, seal test results, and any defects found during installation.
Emergency / Rescue
If water levels rise faster than expected during deployment, withdraw the team immediately using the pre-planned evacuation route. Do not attempt to complete the barrier if the trigger level has been reached. Call 999 if anyone is at risk.
Remember
Deploy barriers well ahead of predicted flood peaks using water level forecast data
Wear personal flotation devices when working near rising water during all deployment activities
Establish a clear evacuation trigger level for withdrawing the deployment team to safety
Test barrier seal integrity at low pressure before water builds against the full system
Position rescue equipment including lifebuoys at the deployment area before work begins
