Which of the following could be a consequence of poorly managed excavation sites?

Poorly managed excavation sites can lead to a variety of safety hazards, and one significant consequence is injury to workers. Excavation activities inherently involve risks such as cave-ins, falls, and equipment accidents. When sites are not properly managed, safety protocols may be overlooked, leading to unstable soil conditions or improper usage of safety equipment. This negligence can directly result in injuries to workers, who may find themselves in hazardous situations due to a lack of adequate safety measures, inadequate training, or insufficient supervision.

The other options do not align with the realities of poorly managed excavation sites. For instance, increased productivity and improvement in soil conditions are the opposite of outcomes expected from poor management; such conditions typically lead to inefficiencies and unmanageable soil crises. Stabilization of the ground typically requires proper management practices and oversight, which would not occur in a poorly managed setting. Thus, the connection between mismanagement and the increased likelihood of worker injury is vital to recognizing the importance of effective site management.
