What is the primary hazard for workers in a roadway construction zone?

The primary hazard for workers in a roadway construction zone is getting struck by vehicles or equipment. This risk arises from the dynamic environment of construction sites where both vehicular and construction traffic are prevalent. Workers are often in close proximity to moving vehicles, including construction trucks and delivery vehicles, as well as to machinery operated by other workers.

Given that construction zones typically involve alterations in traffic patterns and reduced visibility due to ongoing work, the potential for serious injury or fatal accidents due to being struck is significantly heightened. This hazard is underscored by the need for effective traffic control measures, signage, and flagger instructions designed to protect both workers and motorists from potential collisions.

While other hazards, such as exposure to extreme weather, noise pollution, and working with heavy machinery, are important safety considerations in a construction environment, they do not pose the same immediate risk of injury as being struck by vehicles. Emphasizing pedestrian safety and proper signaling can help mitigate the risks associated with vehicle movement in these zones.
