Hazardous Location Linear Fluorescent General-purpose electrical equipment can cause explosions in certain atmospheres. Equipment used in areas where explosive concentrations of dusts or vapors may exist must be equipped with special wiring and other electrical equipment for safety purposes. Hazardous (classified) locations such as these might exist in areas such as aircraft hangars, gasoline stations, paint-finishing locations or agricultural areas such as grain bins. In order to make sure the correct equipment is used, there environments have been broken down into classes, divisions and groups to more specifically identify the hazards. The table below is a summary which explains all classes, groups and divisions. Stanpro Lighting Systems VX4 Series is approved to class1 division 2 groups a,b,c,d and class III division 1 and 2. Summary of Class I, II, II Hazardous Locations Classes I Gases, Vapors and Liquids (Art. 501) II Dusts (Art. 502) Group A. Acetylene B. Hydrogen, etc. C. Ether, etc. D. Hydrocarbons, fuels, solvents, etc. Textiles, woodworking, etc. (easily E.Metal dusts (conductive* and ignitable, but not likely to be explosive) F.Carbon dusts (some are conductive* explosive) and all are explosive) G.Flour, starch, grain, combustible plastic or chemical dust (explosive) Normally explosive and hazardous. Ignitable quantities of dust that is normally or may be, in suspension or conductive dust may be present. Handled or used in manufacturing. Not normally present in an explosive concentration (but may accidentally exist). Dust not normally suspended in an ignitable concentration (but may accidentally exist). Dust layers are present. Stored or handled in storage (exclusive of manufacturing). 1 Divisions 2 III Fibers and Flyings (Art. 503) *Electrically conductive dusts are dusts with a resistivity less than 105 OHM-centimeter. The following tables will better explain the areas where Stanpro Lighting Systems VX4 Series may be installed. Class I, Division 2: One of the following three situations must exist in order for an area to be considered a Class I, Division 2 location. 1 2 A n area where flammable liquids and gases are handled, but not expected to be in explosive concentrations. However, the possibiliby for these concentrations to exist might occur if there was an accidental rupture or other unexpected incident. A n area where ignitable gases or vapors are normally prevented from accumulating by positive mchanical ventilation, yet could exist in ignitable quantities if there was a failure in the ventilation systems. 3 A reas adjacent to Class I, Division 1 locations where it is possible for ignitable concentrations of gas/vapors to come into this area because there isn’t proper ventilation. Class III Class III hazardous locations contain easily ignitable fibers or flyings, but the concentration of these fibers or flyings are not suspended in the air in such quantities that would produce ignitable mixtures. Class III, Division 1 These locations are areas where easily ignitable fibers or items that produce ignitable flying are handled, manufacturer or used in some kind of a process. Class III, Division 2 These locations are areas where easily ignitable fibers are stored or handled. Groups Class I and Class II hazardous locations are further divided into groups: Groups A-G Groups A-D Groups E-G For gases, vapors and liquids. Relate to Class I environment. Describe different dusts that my be encountered in a Class II environment. VX4 Hazardous location linear fluorescent T5, T5HO, T8 – 2 or 3 Lamps Approvals: C22.2 # 137 Class I Div II, groups A, B, C and D T4A and Class III Division 1 & 2, T4A ambient 40 deg c. Description Dimensions The VX4 sealed 4 foot linear luminarie is designed for use in Hazardous locations when gases and liquids may be present. Acetylene, hydrogen, ether, hydrocarbons, fuels, solvants etc. that are not normally present in an explosive concentration (but may accidently exist). The housing is constructed from a one piece reinforced grey fiberglass, a closed cell, high temperature poured in place gasket and polycarbonate latches seal the enclosure from most hostile environments. The low profile housing is available in 4 ft. lengths and is designed around T8, T5 and T5HO lamps for long term enery savings. The VX4 is available in either 2 or 3 lamp options. All fixtures are designed for a 25 degree ambient environment. For 40 degree C hi ambiant temperatures choose the HT option. 2.236" 51.65" 4.38" 6.77" Circuitry SBR Reflector Electronic instant start ballasts are supplied standard in T8 configurations and program start are supplied, standard for T5 and T5HO, other ballast such as LBF, HBF and dimming are optional, please consult factory.
