Many above ground storage tank-related disasters have occurred over history, with some of the greatest being the 1988 Ashland Oil Company disaster, Boston’s Great Molasses Flood that occurred in 1919, and the Caribbean Petroleum Refining Tank Explosion that happened just a few years ago, in 2009.
All these disasters have one thing in common: non-compliance with the standards set for above ground storage tanks. They affected millions of people, with some having even died, and the environment, killing thousands of various animal species.
Avoiding these catastrophic incidents
With the above ground storage tanks (ASTs) playing a huge role in many different industries, it’s a must for owners and operators to do everything they can to avoid the possibility of the above-mentioned tragedies from happening. This is where the API Standards come into play.
There are many API Standard classifications, with the most common ones including API 650 and 620 (welded atmospheric tanks), and API 653 for in-service storage tanks that have a height of more than 50 feet and a diameter of over 30 feet.
By ensuring that you comply with the appropriate standards, you can greatly decrease the possibility of disasters occurring.
The API Standards and what they consist of
Of all the API standards for ASTs, the most commonly used is the API 650. Tanks that fall under this classification store various liquids, including gasoline, oil, produced water, and chemicals. The API 650 standard dictates the designing, processing, welding, inspection, and installation of these tanks.
The API 620 design standard, on the other hand, is for the designing and building of low pressure, but large welded steel tanks.
Then there are the standards for API 653 tanks, which covers the inspection, maintenance, repair, and alteration of ASTs that possess the above-mentioned measurements.
Non-compliance with these standards can cause such a tragic event that will not only affect your business but many people and the environment as well. So make sure you follow the appropriate standards for your ASTs.
