Which action requires command approval and signature?

• A. Overhead spilling
• B. Surface spills
• C. Ground spills
• D. Water spills

Answer: (A)

Spills that start or occur overhead are treated as higher risk and require formal authorization to ensure proper control, safety, and accountability. An overhead spill can involve elevated sources, greater potential for rapid spread, contamination of structures or utilities above, and the possibility of ignition or larger volumes than spills at ground level. Because of these risks, any action to manage an overhead spill typically must go through command review and receive a signature to confirm that safety measures, containment plans, and coordination with appropriate teams are in place before proceeding. This ensures the incident is handled with the appropriate level of oversight and documentation. In contrast, routine responses to surface, ground, or water spills are usually managed under standard operating procedures and reporting channels without requiring command-level sign-off for each step.
