Which organization oversees regulations related to occupational safety in the presence of biohazards?

The correct answer is OSHA, which stands for the Occupational Safety and Health Administration. This agency is responsible for ensuring safe and healthy working conditions for employees by setting and enforcing standards and providing training, outreach, education, and assistance. When it comes to biohazards in the workplace, OSHA establishes regulations and guidelines that employers must follow to protect workers from potential health risks.

OSHA's regulations include standards for bloodborne pathogens, respiratory protection, and various other safety protocols specifically designed to address hazards associated with biological materials. These standards are vital for industries that handle pathogens or other biohazardous materials, ensuring that protective measures are in place to minimize the risk to workers.

In contrast, the CDC (Centers for Disease Control and Prevention) focuses mainly on public health and safety, particularly concerning disease prevention and control. The EPA (Environmental Protection Agency) deals with environmental factors and pollution but does not directly oversee workplace safety regulations. The WHO (World Health Organization) works on a global scale to address health issues, but again, it does not regulate occupational safety at a local or national level.
