Class I Locations
According to the NEC, there are three types of hazardous locations. The first type of hazard is one which is created by the presence of flammable gases or vapors in the air, such as natural gas or gasoline vapor. When these materials are found in the atmosphere, a potential for explosion exists, which could be ignited if an electrical or other source of ignition is present. The Code writers have referred to this first type of hazard as Class I. So, a Class I Hazardous Location is one in which flammable gases or vapors may be present in the air in sufficient quantities to be explosive or ignitable. Some typical Class I locations are:
The only substance in Group A is acetylene. Acetylene makes up only a very small percentage of hazardous locations. Consequently, little equipment is available for this type of location. Acetylene is a gas with extremely high explosion pressures.
Group B is another relatively small segment of classified areas. This group includes hydrogen and other materials with similar characteristics. If you follow certain specific restrictions in the Code, some of these Group B locations, other than hydrogen, can actually be satisfied with Group C and Group D equipment.
Group C and Group D are by far the most usual Class I groups. They comprise the greatest percentage of all Class I hazardous locations. Found in Group D are many of the most common flammable substances such as butane, gasoline, natural gas and propane.
Sizes
15" (SBXC-15MH), 17" (SBXC-17MH), and 20" (SBXC-20M)
Motor
Heavy-duty 1 H.P., UL Listed (Class 1, Group D). Ventilated, ball-bearing, 60 cycle, 115/230 volt, suitable for operation in hazardous locations. 115/230 volt, 50 cycle motor available upon special request.
Brush
Explosion-proof brushes have an aluminum block and brass wire throughout the fill for conductivity.
Use of pad holders or non-approved brushes will void the explosion-proof capabilities of the machine.
Gear Unit
Completely enclosed and sealed planetary-type gear reduction unit required no lubrication. Gear reduction provides speed of 175 R.P.M. on the brush.
Housing
Heavy-duty, reinforced, highly polished cast aluminum brush housing.
Bumper
Extra wide, heavy-duty, conductive rubber bumper provides complete protection.
Handle
Handle assembly is constructed of UL Listed explosion-proof fittings and welded to prevent coming loose. Adjustable through 90 degrees for operator comfort and ease of storage.
Switch
Shock-proof, double pole, momentary switch shuts off when the switch lever is released.
Wheels
Heavy-duty 5" conductive wheels with bronze bushings. Unit retracts when machine is in operation.
Cord
50 ft. UL Approved, heavy-duty 14/3 conductor cable. No plug is provided with the cord.
Construction
Highly polished, heavy duty cast aluminum.
* Available in 15 inch, 17 inch, and 20 inch

The Code writers have referred to this first type of hazard as Class I. So, a Class I Hazardous Location is one in which flammable gases or vapors may be present in the air in sufficient quantities to be explosive or ignitable. Some typical Class I locations are:
- Petroleum refineries, and gasoline storage and dispensing areas;
- Dry cleaning plants where vapors from cleaning fluids can be present;
- Spray finishing areas;
- Aircraft hangars and fuel servicing areas; and
- Utility gas plants, and operations involving storage and handling of liquified petroleum gas or natural gas.
