Which option is not listed as an inspection feature for atmospheric-type tanks?

• A. Interior tank surfaces
• B. Protected sight gauges
• C. Filling and draining connections
• D. Exterior labeling

Answer: (D)

Exterior labeling is not listed as an inspection feature for atmospheric-type foam concentrate storage tanks. In NFPA 16, the inspection features for these tanks focus on elements that affect tank condition and operation: interior tank surfaces are checked for corrosion or residue; protected sight gauges are verified to be readable and protected from damage; and filling and draining connections are inspected to ensure they are accessible, unobstructed, and leak-free. Labeling remains important for safety and identification, but it isn’t considered an inspection feature of the tank itself.
