1.1.1 The purpose of this recommended practice (RP) is to provide guidelines for classifying locations Class I, Zone 0, Zone 1, and Zone 2 at petroleum facilities for the selection and installation of electrical equipment. Basic definitions given in the 2014 edition of NFPA 70, the National Electrical Code (NEC), have been followed in developing this RP. This publication is only a guide and requires the application of sound engineering judgment.
NOTE Recommendations for determining the degree and extent of classified locations Class I, Division 1, and Division 2 are addressed in API 500, Recommended Practice for Classification of Electrical Installations at Petroleum Facilities Classified as Class I, Division 1, and Division 2.
1.1.2 Electrical installations in areas where flammable liquids, gases, or vapors are produced, processed, stored, or otherwise handled can be suitably designed if the locations of potential sources of release and accumulation are clearly defined. Once a location has been classified, requirements for electrical equipment and associated wiring shall utilize applicable publications that apply this document such as NFPA 70 (NEC), CSA C22.1 (Canadian Electrical Code), or API 14FZ.
NOTE There are other publications that establish area classification criteria that may differ from those in this document. Refer to those documents for installation requirements, protection techniques, and wiring methods that align with the area classification criteria applied.
