What is the maximum tank size that can be installed on a higher floor?

The correct answer, which states that the maximum tank size that can be installed on a higher floor is 660 gallons, is based on safety regulations and building codes designed to minimize risks associated with fuel oil storage.

In many jurisdictions, including Maine, the maximum size of oil tanks installed in a higher floor is limited to ensure that in the event of a leak or failure, the amount of fuel that could potentially escape is manageable and contains a lower risk to both the building and the environment. A tank size of 660 gallons is often determined as a practical limit that balances the need for sufficient fuel storage against safety considerations, such as structural integrity and emergency response strategies.

Installing larger tanks, such as those with capacities of 1000 gallons or more, typically requires additional safety measures or may not be permitted on higher floors due to increased risk. This regulation reflects best practices in the industry to prevent spills and protect both the facility and the surrounding area from potential dangers associated with larger volumes of flammable liquids.
