Which option lists the five CO permission items for tagout?

• A. Fueling, dive ops, charging SCBA tanks, disabling FFE
• B. Single closure isolation, fueling, dive ops, charging SCBA tanks, disabling FFE
• C. Single closure isolation, fueling, dive ops, and RCC tasks
• D. Single closure isolation, fueling, dive ops, disabling FFE

Answer: (B)

CO permission items are operations that carry higher risk and require the Commanding Officer’s authorization before applying tagout, to ensure proper oversight and risk control. The five items listed—single closure isolation, fueling, dive ops, charging SCBA tanks, and disabling FFE—are designated as CO permission items because each one presents a significant hazard that deserves extra scrutiny. Single closure isolation is risky because isolating one point of energy can still leave other sources active or create unintended pressure or energy release if not coordinated. Fueling involves flammable liquids and the potential for ignition, making it a high-risk activity that needs formal authorization. Dive operations introduce hazards related to underwater work, breathing gas supplies, and entanglement risks, all of which require elevated coordination. Charging SCBA tanks involves high-pressure gas, a strong safety concern that warrants commanding officer approval to ensure proper procedures and supervision. Disabling fire fighting equipment reduces immediate safety protections, so any decision to do so must be carefully reviewed at the highest level. Other options omit one or more of these items or replace them with activities not designated as CO permission items (for instance, including RCC tasks instead), which is why they do not fit.
