Hoops and grillage on wooden tanks should be inspected how often?

• A. Quarterly
• B. Semi-annually
• C. Annually
• D. Every two years

Answer: (C)

Structural components to support wooden tanks, like hoops and the grillage, are what keep the tank in shape and secure under stress from contents and environment. They’re exposed to moisture, wood decay, insect damage, and fastener corrosion, and foundation settling can affect alignment. Because deterioration can develop gradually yet lead to sudden failure if unchecked, these parts are inspected at a regular, practical interval. Inspecting hoops and grillage annually strikes the right balance: it catches developing issues early (loose bands, rusted fasteners, cracked or rotting wood, or uneven support) without placing an unnecessary burden on maintenance schedules. More frequent checks (quarterly or semi-annual) aren’t typically required unless there are specific risk factors, while waiting two years leaves too much time for problems to progress unchecked.
