Max height of an aboveground flammable and combustible tank shall not exceed how many feet?

• A. 30
• B. 50
• C. 60
• D. 40

Answer: (D)

Safety and design standards limit the height of aboveground tanks containing flammable or combustible liquids to keep firefighting and containment practical. A maximum height of forty feet helps ensure that cooling water or foam can reach and effectively cool the tank, reduces the impact of radiant heat on nearby equipment, and keeps relief and venting systems manageable. Taller tanks would make firefighting harder and increase the risk if a fire occurs, so the forty-foot limit is the standard that balances safety with operations.
