Which device is used to record and authorize the isolation of damaged spaces and systems?

• A. Compartment isolation lists/kill cards
• B. Damage control log
• C. Ventilation schedule
• D. Electrical isolation tags

Answer: (A)

The key idea is how isolation actions are formally documented and authorized during damage control. The tool used for this is the compartment isolation list, commonly called a kill card. It identifies exactly which spaces and systems must be isolated, who authorized the action, and which valves, dampers, doors, or other isolating devices need to be closed. Posting this card in the affected area and circulating it to the control stations ensures every team knows what has been isolated and what remains energized, providing a clear, auditable record and preventing conflicting actions or reentry into a damaged space. A damage control log records overall events, but it doesn’t provide the specific, authorized isolation list for spaces and systems. Ventilation schedules and electrical isolation tags serve more specialized roles—ventilation control and circuit de-energization, respectively—and don’t function as the unified authorization document for isolating damaged areas.
