Recommended Practice for Classification of Locations for Electrical Installations at Petroleum Facilities Classified as Class I, Division 1 and Division 2 - Third Edition; ERRATA: JANUARY 2014
N RP 500
Annotation
This document applies to the classification of locations for both temporarily and permanently installed electrical equipment. It is intended to be applied where there may be a risk of ignition due to the presence of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors, mixed with air, under normal atmospheric conditions (identified throughout this document as "gases and vapors"). Normal atmospheric conditions are defined as conditions that vary above and below reference levels of 101.3 kPa (14.7 psia) and 20 °C (68 °F) provided that the variations have a negligible effect on the explosion properties of the flammable materials.
The following items are beyond the scope of this document.
a) Piping systems used for odorized natural gas used as fuel for cooking, heating, air conditioning, laundry, and similar appliances.
b) Catastrophes such as well blowouts or process vessel ruptures. Such extreme conditions require emergency measures at the time of occurrence.
c) The suitability of locations for the placement of non-electrical incendiary equipment.
d) Classification of locations containing combustible dust, ignitable fibers, or flyings.
Recommendations for determining the degree and extent of classified locations for specific examples of situations commonly encountered in petroleum facilities are given in Section 8 through Section 14. While it is important for area classifications at refineries, production and drilling facilities, and pipeline facilities to agree to some extent, there are differences in production, drilling, transportation, and refining facilities. Some differences include the process conditions, types, and quantities of products handled, the physical size of typical facilities, and varying housing and sheltering practices.
