Installing a hands-free automatic hand sanitizer dispenser in the dental office is an example of which type of hazard control?

Correct answer: C. Engineering control

• A. Administrative controls involve policies, procedures, training, and scheduling changes (e.g., required hand hygiene before patient contact). A physical dispenser that promotes compliance is an engineering enhancement.
• B. PPE includes masks, gloves, and gowns worn by individuals. The dispenser itself is not PPE.
• C. CORRECT. A hands-free automatic dispenser is an engineering control — it modifies the physical environment/equipment to reduce reliance on individual behavior. The device makes proper hand hygiene more accessible and compliant without requiring conscious decision-making at each use.
• D. Work practice controls modify the way tasks are performed (e.g., no-recap rule, one-handed capping technique). Installing a physical device is engineering, not a work practice change.
