Typcially most standard Aerial Work Platforms manufactured in North American meet basic UL ratings and provide minimal protections agains Spark and Shock. In areas where increased protection is needed, NFPA (National Fire Protection Association) has type designations for the various equipment as identified in the table below:
| Fuel Type and Special Design (if any) | Type Designation |
|---|---|
| Electrical (Battery) | E |
| Electrically powered unit that, in addition to meeting all the requirements for Type E units, is provided with additional safe-guards to the electric system to prevent the emission of hazardous sparks and to limit surface temperatures | ES |
| Electrically powered unit that, in addition to meeting all the requirenenu for Type E and ES units, has it's electric motors and all other electric equipmmt completely enclosed | EE |
| Gasoline | G |
| Gasoline powered unit that, in addition to meeting all the requirements for Type G units, is provided with additional safeguards to the exhaust, fuel, and electric systems | GS |
| Diesel | D |
| Diesel with additional safeguards to the exhaust, fuel and electric systems | DS |
| Diesel-powered unit in which the diesel engine and the electric fittings and equipment are so designed, coll!cructed, and assembled that the unit can be used in attmospheres that contain specifically named flammable vapors dusts, and, under cenrtain conditions, fibers | DX |
| Diesel-powered unit and any electric equipment is completely enclosed and equipped with temperature-limitation fearures | DY |
| LPG | LP |
| LPG powered unit that is provided with additional safeguards to the exhaust, fuel, and electric systems | LPS |
| CNG | CN |
| CNG powered unit that is provided with additional safeguards to the exhaust, fuel, and electric systems | CNS |
| Dual Fuel - Gasoline LPG | G LP |
| A unit that operates on either gasoline or liquefied petroleum gasoline and is provided with additional safeguards to the exhaust, fuel and electric systems | GS LPS |
| Dual Fuel - Gasoline CNG | G CN |
| Unit that operates on either gasoline or compressed natural gas and, in addition to meeting all the requirements for Type G CN units, is provided with additional safeguards to the exhaust, fuel, and std electric systems | GS CNS |
| Compressed Gaseous Hydrogen | H2 |
Our team includes members that were on the NFP A (505) and UL (583) standards committees providing design input in the development of these standards. We have designed hundreds of lifts for hazardous locations and can design to most of these type designations.
