Who initiates air monitoring?

• A. Team Leader
• B. Safety Officer
• C. Command Post (CP)
• D. Medical Officer

Answer: (C)

Initiating air monitoring is a function of incident command and hazard management. The Command Post serves as the central hub for coordinating the overall response, setting incident objectives, and directing resources. Because air quality can drive protective actions, time-sensitive decisions, and PPE requirements, it’s the Command Post that initiates monitoring to establish current conditions, identify hazards, and communicate findings to all teams. This centralized initiation ensures data is consistent, properly recorded, and used to guide actions across the operation.

Ground leaders on scene carry out tasks and can request monitoring, and safety personnel provide guidance on safety thresholds, but the authority to start the monitoring process typically rests with the Command Post to maintain coordinated, effective response. The Medical Officer focuses on health assessment and patient care rather than starting environmental monitoring.
