Which potential biological hazard in healthcare facilities is regulated by OSHA?

• A. Airborne diseases
• B. Noise exposure
• C. Blood-borne pathogens
• D. Chemical hazards

Answer: (C)

OSHA regulates biological hazards in healthcare primarily through a dedicated bloodborne pathogens standard. This rule targets the risk of infection from blood and certain body fluids and requires employers to implement an exposure control plan, use universal precautions, apply engineering and work-practice controls, provide appropriate PPE, offer hepatitis B vaccination, and ensure post-exposure evaluation and training. The focus on bloodborne pathogens reflects the real danger healthcare workers face from sharps injuries and exposure to bloodborne pathogens such as HIV, HBV, and HCV, making this the most direct OSHA regulation for a biological hazard in clinical settings. Airborne diseases fall under broader infection-control and public health guidance rather than a single OSHA biological-hazard standard, while chemical hazards and noise are different categories with their own non-biological regulatory frameworks.
