ISO 28300:2008涵盖了地上液态石油或石油产品储罐以及设计为大气储罐或低压储罐的地上和地下冷藏储罐的正常和应急蒸汽排放要求。ISO 28300:2008中讨论了超压和真空的原因；确定通风要求；通风方式；通风装置的选择和安装；以及测试和标记减压装置。 ISO 28300:2008适用于盛装石油和石油产品的储罐，但也适用于盛装其他液体的储罐；然而，当ISO 28300: 2008适用于其他液体。 ISO 28300:2008不适用于外部浮顶储罐。

ISO 28300:2008 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 as atmospheric storage tanks or low-pressure storage tanks. Discussed in ISO 28300:2008 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. ISO 28300:2008 is 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 ISO 28300:2008 is applied to other liquids. ISO 28300:2008 does not apply to external floating-roof tanks.
