Safety Shooter safety glasses, and hearing protection. The signs, traffic cones, arrow and message boards, crash trucks, and safety attenuators must be properly positioned and in accordance with the appropriate DOT traffic pattern requirements. Fatal accidents can happen in an instant. Therefore, construction personnel need to be aware and vigilant at all times when working near moving traffic. Old railroad tunnels and bridges over rural roads are often narrow two-lane roads and there isn’t much room to work on abutment or tunnel walls. In such cases, it often necessary to set up a traffic pattern with flaggers and alternate the traffic. One lane is closed off where the repair operations are taking place while traffic in each direction alternates in the remaining open lane. In very tight circumstances like this, it is usually necessary to hang tarps, erect barriers, or tie plastic to erected scaffolding to protect the passing cars from shotcrete overspray and rebound. Whenever a lane is closed or restricted it is imperative to have the proper warning signs in place for approaching motorists (refer to Fig. 3 and 4). Each project has different safety issues. Whether you are working on a rural two-lane road or on a heavily traveled highway, it is important to address the specific safety issues of that location. Set up the appropriate traffic configuration, make sure the workers are protected at all times, and make sure any necessary barriers or tarps are securely in place before the start of shotcrete operations.
