Which statement is true regarding ventilation adequacy assessment?

• A. It is determined by the Facilities Manager.
• B. It is determined by the Plant Supervisor.
• C. It is determined by the Safety Officer.
• D. It is determined by the Safety Committee.

Answer: (C)

Ventilation adequacy assessment is a safety-related function focused on protecting workers from airborne hazards and ensuring compliance with exposure limits. The Safety Officer is the person who oversees safety programs, monitors conditions, and determines whether controls like ventilation meet required standards. They analyze monitoring data, verify that air exchange rates, filtration, and contaminant dilution are sufficient, and ensure corrective actions are taken if limits are exceeded. While the Facilities Manager maintains the HVAC systems and the Plant Supervisor handles daily operations, and the Safety Committee reviews policies, the formal determination of whether ventilation is adequate rests with the Safety Officer because it directly addresses worker health and safety compliance.
