Hazards of the road: Working in traffic is a two-pronged safety proposition: both you and the drivers coining at you need to be on high alert

摘要

The accident: A worker was cutting concrete along the white center line of a four-lane highway. Orange reflective barrels closed the left lane to traffic, which was routed to a single lane. To accommodate the concrete cutting, three to four barrels had been moved into the active traffic lane, with a flagperson slowing down traffic and directing it slightly onto the berm area. An approaching semi truck exceeded the speed limit. The driver lost control of his vehicle and hit the guard rail. The truck bounced back from the guard rail through the barrels and struck the worker from behind, killing him.
