How often should an above ground fuel tank be inspected? Well, that's a question I get asked a lot as a supplier of above ground fuel tanks. In this blog, I'll share my insights on this crucial topic and give you the lowdown on how often you should have your tank checked out.


First off, let's talk about why inspections are so important. Above ground fuel tanks store flammable substances, and any issues with the tank can pose a serious risk. Leaks can contaminate the soil and groundwater, and in the worst - case scenario, they can lead to fires or explosions. Regular inspections help catch problems early, ensuring the safety of your property, the environment, and everyone around.
Factors Affecting Inspection Frequency
There isn't a one - size - fits - all answer to how often an above ground fuel tank should be inspected. A bunch of factors come into play.
Tank Material
The material of the tank has a big impact. Steel tanks are common, but they're prone to rust and corrosion over time. If you've got a steel Above Ground Gasoline Fuel Tank, it'll probably need more frequent inspections compared to a fiberglass tank. Fiberglass is more resistant to corrosion, so it might not need to be checked as often.
Tank Age
Newer tanks generally have fewer issues. But as a tank gets older, the likelihood of problems increases. A brand - new Above Ground Diesel Fuel Tank might be fine with less frequent inspections in the first few years. However, once it hits 10 or 15 years old, you'll want to step up the inspection schedule.
Usage and Environment
How you use the tank matters. If it's constantly being filled and emptied, it'll experience more wear and tear. Also, the environment where the tank is located is crucial. Tanks in harsh environments, like near the ocean where there's a lot of salt in the air, or in areas with extreme temperatures, will need more regular inspections. Salt can accelerate corrosion, and extreme temperatures can cause the tank material to expand and contract, leading to cracks.
General Inspection Guidelines
Based on industry standards and my experience as a supplier, here are some general guidelines for inspection frequency:
Monthly Checks
You should do some basic checks on your own every month. Look for any visible signs of damage, like dents, cracks, or leaks. Check the tank's level to make sure there aren't any sudden drops, which could indicate a leak. Also, look at the area around the tank for any signs of fuel spills or stains.
Quarterly Inspections
Every three months, it's a good idea to have a more thorough inspection. This can be done by a trained technician. They'll check the tank's fittings, valves, and connections to make sure they're all in good working order. They'll also look at the tank's structural integrity, looking for any signs of corrosion or weakening.
Annual Inspections
Once a year, a comprehensive inspection should be carried out. This includes a detailed visual inspection of the entire tank, both inside and out if possible. The technician will use specialized equipment to check for hidden defects, like ultrasonic testing to detect internal corrosion. For Above Ground Diesel Tank, they'll also check the fuel quality to make sure it's still suitable for use.
Special Circumstances
If there's been an event that could potentially damage the tank, like an earthquake, a severe storm, or a nearby impact, you should have the tank inspected immediately. Even if there are no visible signs of damage, there could be internal issues that need to be addressed.
The Importance of Professional Inspections
While you can do some basic monthly checks on your own, professional inspections are crucial. Trained technicians have the knowledge and tools to detect problems that might not be visible to the untrained eye. They're also familiar with the latest industry standards and regulations, ensuring that your tank is compliant.
When you hire a professional for an inspection, make sure they're certified and experienced in working with above ground fuel tanks. They should provide you with a detailed report of the inspection, including any findings and recommendations for repairs or maintenance.
Benefits of Regular Inspections
Regular inspections aren't just about safety. They also save you money in the long run. By catching problems early, you can avoid costly repairs or even having to replace the entire tank. A small leak caught early can be fixed with a simple patch, but if it's left undetected, it could lead to a major spill and require a full tank replacement.
Regular inspections also help you maintain compliance with local and federal regulations. Non - compliance can result in hefty fines, so it's in your best interest to keep your tank in good condition and have it inspected regularly.
Conclusion
So, how often should an above ground fuel tank be inspected? It depends on a variety of factors, but in general, monthly self - checks, quarterly inspections by a technician, and annual comprehensive inspections are a good starting point. Don't forget to have the tank inspected immediately after any potentially damaging event.
