Which of the following types of work isn't considered potentially hazardous to maternal health by the Occupational Safety and Health Act?

The reason that work involving driving transportation vehicles is not considered potentially hazardous to maternal health by the Occupational Safety and Health Act relates to the environment and risks associated with such tasks compared to the other listed jobs. While all jobs may have inherent risks, driving transportation vehicles typically involves less exposure to physical hazards that directly impact maternal health, such as heavy lifting, exposure to toxic substances, or extreme physical exertion found in roles like warehouse loading, manufacturing assembly, and construction labor.

In contrast, tasks like warehouse loading and construction labor often involve manual handling of heavy loads, working with hazardous materials, or exposure to accidents that can put maternal health at greater risk. Manufacturing assembly may similarly involve working with machinery or chemicals that could affect a pregnant worker.

Therefore, driving transportation vehicles is characterized as having a lower risk profile concerning maternal health in this context. This assessment is aimed at ensuring the safety and well-being of expectant workers within the workforce.
