Final answer:
The primary cause of death and injury in roadway work zones is not directly stated in the provided data but traffic accidents due to driver error are a significant hazard. Construction workers and truck drivers face high fatality rates, suggesting work zone risks. Safety measures are vital for protection.
Step-by-step explanation:
The number one cause of death/injury in roadway work zones is not explicitly provided by the Bureau of Labor Statistics (BLS) or the CDC in the given references. However, it is well-documented that traffic accidents, often due to driver error, are a significant concern in work zones. In general, head and traumatic brain injuries, which include those from automobile accidents, are major contributors to workplace fatalities and could be extrapolated as a prominent risk in roadway work zones. These statistics underscore the importance of safety measures and regulations to protect workers in these hazardous conditions.
According to the information given, factors such as driver error and the absence of adequate traffic signals can significantly increase the risk of accidents and fatalities in these areas. Construction workers and those involved in transportation (truck drivers) are listed among occupations with a high number of fatalities, which can imply the inherent risks of roadway work zones. Enhanced safety protocols, including proper signage, barriers, reduced speed limits, and worker visibility, are crucial to prevent accidents and save lives.
