Final answer:
Local regulations based on the International Fire Code typically limit the storage of fuel-oil inside of a building to 660 gallons per story for protected tanks, or 60 gallons for non-protected tanks. However, it's important to check specific local building codes and NFPA standards for accurate limits and compliance.
Step-by-step explanation:
The question pertains to a regulation or code limit on the storage of fuel-oil inside of a building. The International Fire Code (IFC) and the National Fire Protection Association (NFPA) both provide standards for the storage of flammable and combustible liquids within buildings. While the exact limit can vary based on local amendments, as a general rule, the IFC (International Fire Code) limits the amount of fuel oil stored above the lowest floor inside of a building to no more than 660 gallons per story in protected aboveground tanks. If the tanks are not protected, the limit is reduced to 60 gallons per story. However, compliance with local building codes and regulations, as well as the specific guidelines outlined in the NFPA 30: Flammable and Combustible Liquids Code, is crucial for the accurate determination of allowed quantities. These regulations are established to ensure fire safety within buildings.
