The correct use and operation of oil storage tank is directly related to the production safety and oil loss of oil tank. In order to use and operate the API standard 650 tanks correctly, it is necessary to be familiar with and master the structure and performance of the API standard 650 tanks and its accessories, such as the maximum storage capacity of the oil tank, the pressure range that can bear and the safety fabrication specification.

Aftershock Level Earthquake (ALE)
This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.
If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API standard 650 tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.
