| Step | Potential Hazard | Control |
|---|---|---|
| Inspect culvert site and surrounding area | Traffic hazards, unstable shoulders, washouts, wildlife | Evaluate roadway conditions, inspect for erosion or soft ground, establish safe work zone, watch for snakes or other animals |
| Position jet truck and establish traffic control | Struck by traffic, vehicle rollaway | Park on stable ground, set parking brake, use wheel chocks, deploy cones and signs according to MUTCD requirements |
| Inspect jetting equipment and hoses | Hose failure, damaged fittings, leaks | Conduct pre use inspection, replace worn hoses or nozzles, verify all connections are secure |
| Access culvert inlet or outlet | Slips, trips, falls, drowning hazards | Maintain stable footing, avoid steep embankments, stay alert for flowing water and slippery surfaces |
| Set up jetting hose and nozzle | Hose whipping, splash exposure, pinch points | Secure hose properly, keep crew clear of hose path, wear waterproof PPE |
| Start jetting operation | High pressure injection injury, flying debris, noise | Use lowest effective pressure initially, keep nozzle pointed into culvert only, wear hearing protection and eye protection |
| Advance hose through culvert | Sudden hose movement, blocked culvert release, debris discharge | Maintain firm control of hose, communicate with operator, stand clear of outlet when blockage breaks free |
| Remove debris from culvert ends | Sharp objects, biological hazards, back strain | Use tools instead of hands when possible, wear gloves, lift debris properly, avoid direct contact with contaminated material |
| Monitor water flow and roadway conditions | Flooding, erosion, roadway undermining | Observe flow direction and discharge, stop work if erosion or washout develops |
| Shut down and disconnect equipment | Residual pressure, hose whipping | Relieve pressure before disconnecting hoses, reel hoses carefully, inspect equipment before storage |
| Restore site and remove traffic control | Worker exposure to traffic, leftover debris | Remove debris from roadway and ditch, retrieve signs and cones safely, inspect site before reopening fully |
Always have a complete, well-stocked first aid kit available.
