In BE containment, administrative controls primarily operate through which mechanism?

• A. Engineering controls through airflow optimization.
• B. Personal protective equipment deployment strategies.
• C. Emergency response drills and signage.
• D. Policies and procedures governing safe work.

Answer: (D)

Administrative controls guide how work is performed by establishing rules, training requirements, and standard procedures that workers follow to maintain containment. In BE containment, these controls shape safe work through written policies, standard operating procedures, permissible task sequences, access restrictions, and required training. They influence behavior and workflow rather than altering the physical environment. This is why policies and procedures governing safe work are the primary mechanism. Engineering controls through airflow optimization change the facility or equipment, PPE deployment relates to individual protection, and while drills and signage support safety, they don’t by themselves define how the work is conducted.
