Which agency focuses on health risks in the workplace and establishes exposure limits?

The chosen response is correct because the National Institute for Occupational Safety and Health (NIOSH) specifically focuses on the recognition, prevention, and control of workplace health and safety hazards. It conducts research and makes recommendations to prevent work-related illnesses and injuries. NIOSH establishes recommended exposure limits (RELs) for various substances and conditions that could pose health risks to workers.

NIOSH operates under the Centers for Disease Control and Prevention (CDC) but is distinct in that its primary mission is concerned with occupational safety and health. It provides crucial guidance and recommendations that help protect employees from hazardous exposures in the workplace.

In contrast, the other agencies mentioned have different roles. The Occupational Safety and Health Administration (OSHA) mainly focuses on ensuring safe and healthful working conditions by setting and enforcing standards, but it does not conduct research or set exposure limits like NIOSH. The Environmental Protection Agency (EPA) primarily addresses environmental hazards and regulations, while the CDC is more oriented toward public health issues and disease prevention, rather than specifically workplace safety.
