Which category of controls is specifically designed to remove or isolate hazards in the workplace from exposure to bloodborne pathogens?

• A. Engineering Controls
• B. Administrative Controls
• C. PPE
• D. Surveillance

Answer: (A)

Engineering controls are designed to remove or isolate hazards in the workplace from exposure to bloodborne pathogens by changing the way work is done or the equipment used, so the hazard is less likely to come into contact with workers. They physically separate the hazard or remove it—think safety-engineered sharps devices that retract or shield the needle, closed or sealed systems for specimen collection, and biosafety cabinets that prevent splashes and aerosols. PPE provides a barrier but doesn’t remove the hazard itself and relies on proper use and consistent adherence. Administrative controls involve policies and training, while surveillance monitors exposure and health outcomes.
