Which of the following is an administrative control in ICRA?

• A. Site-specific procedures, access policies, and staff training
• B. Negative pressure ventilation
• C. Gloves and respirators
• D. Sealing barriers

Answer: (A)

Administrative controls are management-based measures that shape how work is performed and who is allowed to access areas, without changing the physical environment. Site-specific procedures tell workers exactly how tasks should be done, access policies determine who can enter restricted areas, and staff training ensures everyone understands the protocols and the reasons behind them. Together, these elements reduce exposure by guiding behavior, ensuring consistency, and promoting compliance.

Engineering controls, like negative pressure ventilation, modify the environment to contain or remove contaminants rather than altering behavior. PPE such as gloves and respirators provides personal protection but does not change how work is conducted or who is allowed in. Sealing barriers create physical separation to limit spread, which is also a physical/engineering approach.
