FPN) Through the exercise of ingenuity in the layout of electrical installations for hazardous (classified) locations, it is frequently possible to locate much of the equipment in less hazardous or in nonhazardous locations, and, thus, to reduce the amount of special equipment required. [Pg.636]

All other applicable rules contained in this Code shall apply to electrical equipment and wiring installed in hazardous (classified) locations. [Pg.636]

FPN) Explosionproof apparatus is defined in Article 100. For further information, see Explosionproof and Dust-Ignitionproof Electrical Equipment for Use in Hazardous (Classified) Locations, ANSI/UL 1203-1988. [Pg.637]

NFPA 497A—Recommended Practice for Classification of Class I Hazardous (Classified) Locations for Electrical Installations in Chemical Process Areas contains recommendations for wiring requirements in an enclosed area where lighter-than-air flammable gases may be released [5.12]. While these recommendations are for chemical processing areas, the releases are similar in the hazard they present to what would be found for natural gas released in repair garages. These recommendations are also illustrated in Figure 5-1. [Pg.147]

A detailed account of the factors to be considered when designing electrical distribution systems for chemical process plants and the equipment used (transformers, switch gear, and cables) is given by Silverman (1964). Requirements for electrical equipment used in hazardous (classified) locations are given in the National Electrical Code (NFPA 70), as described in Section 9.3.5. [Pg.1075]
