We can develop drawings based on client requirements or we can also provide code review service to assist our clients in determining and identifying the correct hazardous area classification for a project. This classification is then documented, including ratings of equipment used in the hazardous areas. Name plate reading exercise for Ex d, Ex e and Ex i 6. The materials suitable for hazardous areas Aggression light, good behavior (acceptable) Dato non disponibile Not available data Aggressione forte, non adatto (non utilizzare) Aggression strong, not suitable (not used) Nessuna aggressione, ottimo comportamento (eccellente) No aggression, excellent behavior (excellent) Acetylene Acetone Fatty. 1 • Zone 0, Group IIC • Zone 20, Group IIIC 8CHG Safe area Battery Charger Unclassified, non-hazardous locations only (Ord Loc) 8AIS Intrinsically Safe AC Input Rating 8CHG only: 14 F to 86 F. The NEC recognizes three classes of hazardous areas: Class I locations are characterized by the presence of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors. NEMA Definitions Pertaining to Non-Hazardous Locations: Type Description 1 Intended for use primarily to provide a degree of protection against limited amounts of falling dirt. There are certain work environments that have been specifically classified as hazardous due to the nature of the materials used in that environment. This Hazardous Area Classification Guide explains in easy terms electrical hazardous classifications which makes this eBook a great industrial electrical training tool. NEC Hazardous Area Classifications The NEC, or National Electric Code, sets the standard for the safe installation of electrical wiring and equipment in the United States. Preventive measures aimed at the elimination of the risk of a simultaneous occurrence of a source of ignition and an explosive atmosphere in the area under consideration may be used. Curious on other opinions on who should determine the extent of the hazardous area(s). 1%), and unclassified as having. This information will then help to specify the special electrical and electronic equipment for each hazardous area, and will also help with the elaboration of safety procedures for plant operation and maintenance. Electrical equipment installation in atmosphere with flammable gases or vapors, flammable liquids, combustible dusts, ignitable fibers or flyings represents a risk for fire and explosion. • determine the appropriate protection concept : intrinsic safety, flameproof, etc.
