Quick Answer
The recommended height for fuel storage tanks is typically between 3 and 6 feet above grade to allow for proper drainage and to prevent water accumulation, which can lead to corrosion and other safety hazards. This height also facilitates easy maintenance and inspection. Local regulations may dictate specific requirements.
Local Regulations and Safety Codes
When it comes to fuel storage tanks, local regulations and safety codes play a significant role in determining the recommended height. For example, the International Fire Code (IFC) and the National Fire Protection Association (NFPA) provide guidelines for fuel storage tank placement and elevation. In many jurisdictions, fuel storage tanks must be at least 3 feet above grade to prevent water accumulation and reduce the risk of fires.
Tank Elevation and Drainage
Elevating fuel storage tanks above grade is crucial for proper drainage. Water can seep into the tank through the rim or other openings, leading to corrosion and other safety issues. To ensure proper drainage, the tank should be elevated on a solid foundation or concrete slab. The IFC recommends a minimum of 1/4 inch per foot slope to direct water away from the tank. For example, a 6-foot tall tank should have a slope of at least 6 inches to prevent water accumulation.
Maintenance and Inspection Access
Elevating fuel storage tanks also facilitates easy maintenance and inspection access. A height of 3-6 feet above grade provides enough clearance for technicians to access the tank and perform routine maintenance without the need for ladders or specialized equipment. This can help reduce the risk of accidents and ensure that the tank is properly serviced.
