Any valve operation must be performed in coordination with:

• A. Incident Commander.
• B. Safety officer.
• C. Facility personnel supervision.
• D. Engine company officer.

Answer: (C)

Valve operations affect a building’s utility systems and can have wide-ranging consequences if not handled correctly. Coordinating with the facility personnel supervisor ensures the right valve is identified, the correct sequence is followed, and any impact on other systems or occupants is anticipated and managed. The facility supervisor knows where valves are, what they control, and how shutting or opening them will affect the building’s operations, interlocks, and safety measures. They can also coordinate with maintenance, security, and occupants to minimize risk and ensure a safe, orderly isolation if needed.

While the incident commander directs overall strategy and the engine company officer leads tactical hose and pump actions, valve isolation is a specialized task that hinges on building systems knowledge and access—which the facility personnel supervisor provides. The safety officer focuses on hazards and protective actions, but does not typically control building system isolations.
