2019-11-18 10:51 Division into three groups in Class II locations is for the same reasons Class I locations are divided into Groups A, B, C and D: equipment design and area classification. However the three Class II groups (Groups E, F& G) are based on different characteristics than the four Class I groups because the design characteristics are different.

Class II hazardous locations are areas where combustible dust, rather than gases or liquids, may be present in varying hazardous concentrations. Class II locations are further subdivided into two divisions. Class II, Division 1: One of the following three situations must exist in order for an area to be considered a Class II, Division 1 location: division 2 area classification For more information on our available services for Class 1, Division 2 hazardous locations motors, contact the team or request a quote today.

ClassDivision System. The ClassDivisionGroup system is based on Article 500 of the National Electrical Code (NEC) where. Classes defines the general nature of the hazardous material in the surrounding atmosphere. Divisions defines the probability of hazardous material being present the surrounding atmosphere. A Class II, Division 1 location is a location In which combustible dust is in the air under normal operating conditions in quantities sufficient to produce explosive or ignitible mixtures, or Where mechanical failure or abnormal operation of machinery or equipment might cause such explosive or ignitible mixtures to be produced, and might also Class I, Division 2 or Zone 2 classified locations. An area where ignitable concentrations of flammable gases, vapors or liquids are not likely to exist under normal operating conditions. In this area the gas, vapor or liquids would only be present under abnormal division 2 area classification ClassDivision Hazardous Location 2 Table of Contents This is an important factor in the classification of hazardous areas. Flammable liquids with a high flash point are less hazardous than liquids with a low flash point. Flammable Solids Dust, fibers, and flyings
