OSHA's Bloodborne Pathogens standard aims to protect workers from exposure to blood and other potentially infectious materials. It requires employers to implement an exposure control plan, use universal precautions, provide personal protective equipment and engineering controls when exposure risks exist, offer hepatitis B vaccinations, conduct training, and maintain medical and injury records. The standard covers facilities where workers may come into contact with blood or bodily fluids as part of their jobs, such as in healthcare, laboratories, and emergency response.
