What is the role of the National Institute for Occupational Safety and Health (NIOSH)?

The National Institute for Occupational Safety and Health (NIOSH) primarily focuses on conducting research and providing recommendations to prevent work-related injuries and illnesses. Its role encompasses a wide range of health and safety issues, including those related to exposure to hazardous substances like pesticides. By researching the effects of occupational exposures, NIOSH is able to develop guidelines and standards that help protect workers, thus improving workplace safety.

This function is crucial in understanding how pesticide exposure may contribute to health risks for workers in agricultural and pest control settings. Through their research activities, NIOSH can provide valuable data and insights that inform policies and practices to safeguard the health of those who may come into contact with pesticides in their jobs.

In contrast, the other options reflect responsibilities that do not fall under NIOSH's jurisdiction. For example, regulating pesticide sales involves agencies such as the Environmental Protection Agency (EPA), providing pest control services is typically the role of commercial pest control companies, and certifying all chemical compounds would be more aligned with regulatory bodies focused on chemical safety rather than a research-focused entity like NIOSH.
