Multiple Choice

Exterior painted, coated, or insulated surfaces of the tank and supporting structure shall be inspected for signs of degradation. How often?

Explanation:
Regular inspection of exterior coatings on tanks and their supporting structures is done on an annual basis because these surfaces are exposed to weather and slowly develop issues like paint peeling, blistering, chalking, rust on exposed metal, and damage to any insulation or cladding. A yearly check is enough to spot signs of degradation early and plan maintenance before leaks or structural problems occur, without the inefficiency of checking every month or every few months. If conditions are unusually harsh (salt spray, chemicals, or aging coatings), more frequent checks may be warranted, but the standard interval is once per year.
