API Tank Code Books, UL (Underwriters Laboratory) Codes, and NFPA Codes relating to aboveground storage tanks AST
An aboveground storage tank (AST), sometimes improperly spelled ‘above ground storage tank,’ is a tank that is placed or installed above grade or above the ground. Unlike an UST (Underground Storage Tank), the above ground storage tank is prone to fire hazards and other natural hazards and conflagrations. The UST usage and code was created to combat the fire hazards of tanks since they are underground; however, a UST new hazard environmental developed as a result of the Clean Water Act. All Regulators rely heavily on the American Petroleum Industry, the Underwriters Laboratory and the National Fire Protection Association for national and international uniform codes and inspector certification.
The American Petroleum Institute (API) was established in 1919 for the benefit of national interests. API is one of the oldest and most successful set of standards with beginning in 1924 and now maintains some 500 API standards for the oil and gas industry both national and global because of the International Standards Organization (ISO). API also provides the international standards for Tank Inspector certifications and the code books that the inspectors are require to have at all times with current addendums. These come in sets including the API-650 and API-653 code books with ASME Section IX Welding code book - for more on the ASME code books click here!
The NFPA (National Fire Protection Association) code books are used in conjunction with the API code books and standards that compliments the requirements from a design safety of fuel oil and gas systems to maintenance of tanks and this includes water tanks as well.
