What was the main purpose of NIOSH?

The National Institute for Occupational Safety and Health (NIOSH) was established to promote workplace safety and health, making the correct choice focused on enhancing safety standards in various work environments. NIOSH conducts research and makes recommendations to prevent workplace-related injuries, illnesses, and fatalities. Their work includes identifying hazardous conditions and providing guidance for safety practices and regulations to protect workers across industries.

The other options touch on important aspects of health and safety regulations, but they do not capture the core mission of NIOSH. While guidelines for mental health, drug manufacturing regulations, and overseeing healthcare reimbursements are essential elements in the broader context of public health, they fall outside the primary focus of NIOSH, which is specifically dedicated to occupational safety and health issues.
