Below are some of the more relevant standards that influence the design selection and maintenance of tank related equipment. HMT cannot provide these standards directly. However, provided below are links below to the relevant organization pages where the standards can be ordered. The list below is in no way meant to be a comprehensive list or implied to be applicable to any project.


NFPA 11 - Standard for Low, Medium and High-Expansion Foam: National Fire Protection Association Standard 11 is the standard that covers the design, installation, operation, testing and maintenance of low, medium and high expansion foam systems for fire protection. This standard does not specify where foam protection is required. 

NFPA 30 - Flammable and Combustible Liquids Code: National Fire Protection Association Standard 30 is enforceable under OSHA and many state and local regulations. NFPA 30 provides safeguards to reduce the hazards associated with the storage, handling and use of flammable and combustible liquids. 

NFPA 780 Standard for the Installation of Lightning Protection Systems: National Fire Protection Association Standard 780 provides lightning protection system installation requirements to safeguard people and property from the risk and related hazards associated with lightning exposure.


API 650 - Welded Tanks for Oil Storage: API Std 650 establishes minimum requirements for material, design, fabrication, erection, and testing for vertical, cylindrical, aboveground, closed- and open-top, welded carbon or stainless steel storage tanks in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure is permitted when additional requirements are met. This Standard applies only to tanks whose entire bottom is uniformly supported and to tanks in non-refrigerated service that have a maximum design temperature of 93°C (200°F) or less.

API 653 - Tank Inspection, Repair, Alteration, and Reconstruction: Covers the inspection, repair, alteration, and reconstruction of steel aboveground storage tanks used in the petroleum and chemical industries. Provides the minimum requirements for maintaining the integrity of welded or riveted, nonrefrigerated, atmospheric pressure, aboveground storage tanks after they have been placed in service.

API 2000 - Venting Atmospheric and Low-pressure Storage Tanks: Covers the normal and emergency vapour venting requirements for aboveground liquid petroleum or petroleum products storage tanks and aboveground and underground refrigerated storage tanks, designed for operation at pressures from full vacuum through 103,4 kPa (ga) [15 psig]. Discussed in this International Standard are the causes of overpressure and vacuum; determination of venting requirements; means of venting; selection, and installation of venting devices; and testing and marking of relief devices.

Intended for tanks containing petroleum and petroleum products but it can also be applied to tanks containing other liquids; however, it is necessary to use sound engineering analysis and judgment whenever this International Standard is applied to other liquids.

This International Standard does not apply to external floating-roof tanks.

This edition of API Std 2000 is the identical national adoption of ISO 28300:2008, Petroleum, petrochemical and natural gas industries-Venting of atmospheric and low-pressure storage tanks.

API RP 545 - Lightning Protection of Aboveground Storage Tanks for Flammable or Combustible Liquids: API RP 545, Recommended Practice for Lightning Protection of Above Ground Storage Tanks for Flammable or Combustible Liquids, First Edition, replaces the requirements of API 2003 regarding lightning protection for preventing fires in storage tanks with flammable or combustible contents. This recommended practice (RP) provides guidance and information to assist owners/operators with lightning protection for tanks. This RP does not provide complete protection for all possible lightning stroke occurrences.


AWWA D108-10 - Standard for Aluminum Dome Roofs for Water Storage Facilities: This standard establishes minimum criteria for the design, fabrication and erection of structurally supported aluminum dome roofs. Aluminum dome roofs can be used on any size tank erected in accordance with AWWA standards. When this standard is specified, in the case of conflict between this standard and any other standard, the requirements of this standard shall govern.


Aluminum Design Manual: The Aluminum Association produces an Aluminum Design Manual, essential for all professionals who work with aluminum in structural applications.
