What is the key focus of the Occupational Safety and Health Administration?

The key focus of the Occupational Safety and Health Administration is to ensure that workplaces are safe and healthful for employees by setting and enforcing standards. The agency aims to reduce workplace hazards and implement safety best practices, thus creating a safer environment for workers. This involves establishing regulations that address toxic substances, machinery safety, fall protection, and ergonomics, among other aspects of workplace safety. By prioritizing hazard-free workplace standards, OSHA plays a vital role in preventing injuries, illnesses, and fatalities related to occupational environments.

The other options address important areas, such as environmental conservation, food safety regulations, and healthcare standards, but they fall outside OSHA's primary mandate, which is focused solely on occupational safety and health in various industries.
