| Step | Potential Hazard | Control |
|---|---|---|
| Evaluate closure location and traffic conditions | High speed traffic, limited visibility, blind curves, poor lighting | Review plan in advance, choose safest closure points, consider additional warning devices, verify adequate sight distance |
| Deploy advance warning signs | Struck by vehicles, confused motorists, improper sign spacing | Follow MUTCD spacing tables, place signs from upstream to downstream, always face traffic when placing signs |
| Position work vehicles with warning lights | Rear end collisions, inadequate buffer space | Use truck mounted attenuators when available, park at angle to shield workers, activate amber beacons and four way flashers |
| Establish taper and closure devices | Worker exposure in live lane, wrong taper length, inattentive drivers | Place cones or barrels starting from shoulder and working into lane, maintain proper taper length, remain alert and face oncoming traffic |
| Install Type III barricades and road closed signs | Lifting injuries, pinched fingers, struck by passing vehicles | Use team lifting for large barricades, set legs properly, position barricades perpendicular to traffic |
| Set up detour or alternate route signs | Motorist confusion, wrong way travel, device placement errors | Confirm detour path is safe and clearly marked, place guide signs at each turn, verify visibility by driving route if possible |
| Confirm closure is working as intended | Drivers entering closure zone, device displacement | Assign lookout or supervisor to observe traffic flow, reposition devices as needed, adjust taper or signage if motorists appear confused |
| Perform work activities within closed road | Workers struck by equipment inside work zone, unauthorized vehicle entry | Maintain secured perimeter, keep barricades in place, use spotters around equipment, maintain radio communication |
| Remove devices and reopen road | Worker exposure during takedown, drivers entering before ready | Retrieve devices in reverse order of setup, keep workers inside buffer space, signal clearly when road is open |
| Conduct post operation review | Incorrect placement, missing devices, communication issues | Review any close calls, document adjustments needed, update closure plans for future work |
