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).

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.

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.
