Site Traffic & Vehicle Management - Separating People and Wheels

Welcome back, let's Build Smart & Build Safe! We've covered falling objects and moving loads. Today, we're focusing on another major "struck-by" hazard: site traffic and vehicle management. On any active construction site, vehicles and pedestrians must coexist, but safely separating them is critical to preventing collisions.

The dynamic nature of a job site means trucks, forklifts, excavators, and other vehicles are constantly in motion. Without clear rules and designated zones, the risk of a worker being struck by a vehicle escalates dramatically.

1. The Site Traffic Management Plan: Your Roadmap to Safety

• Comprehensive Plan: Every site should have a clear, written plan detailing how vehicles and pedestrians move. This includes:

  • Designated entry/exit points.

  • One-way systems where feasible.

  • Speed limits appropriate for site conditions.

  • Parking areas for personal and work vehicles.

• Communicate the Plan: Ensure all workers, visitors, and delivery drivers understand and adhere to the site's traffic plan.

2. Pedestrian Walkways: Creating Safe Lanes for People

• Separation is Key: Wherever possible, physically separate pedestrian routes from vehicle travel lanes. Use barriers, fencing, cones, or painted lines.

• Clear & Maintained: Ensure pedestrian walkways are well-lit, clear of obstructions, and properly maintained.

• No Shortcuts: Encourage workers to use designated walkways, even if it means taking a slightly longer route.

3. Backing Safety: The Most Dangerous Maneuver

• Blind Spots: Every vehicle has blind spots, especially large trucks and heavy equipment. Never assume an operator can see you.

• Spotters are Critical: Always use a trained spotter when backing up or when an operator's view is obstructed. Maintain clear communication (radio, hand signals).

• Alarms & Mirrors: Ensure all vehicles have functioning backup alarms and properly adjusted mirrors.

• "Go-Zones": Designate areas where workers should never enter when a vehicle is backing up.

4. Work Zone Safety (Roadway Adjacent Sites): Protecting Workers Near Public Traffic

• Traffic Control Plan: For work impacting public roadways, a detailed traffic control plan (TCP) is essential, outlining cones, barrels, signs, and flagging operations.

• Flaggers: Trained flaggers must wear high-visibility apparel and use clear, standardized signals to direct traffic and protect workers.

• High-Visibility Clothing: All workers operating in or near vehicle traffic (on-site or public roads) must wear high-visibility (fluorescent and reflective) clothing.

5. Be Seen, Be Heard, Be Aware:

• Make Eye Contact: If you must approach a vehicle, try to make eye contact with the operator. Get their acknowledgment that they see you.

• Never Assume: Always assume an operator cannot see you, especially when you are in a blind spot.

• Maintain Distance: Keep a safe distance from moving vehicles at all times.

Implementing a robust site traffic management plan and enforcing strict backing and pedestrian safety rules are fundamental to preventing "struck-by" incidents. Tomorrow, on Fall Protection Friday, we'll look at the dual dangers of being struck by objects or equipment when working at height.
