This standard was first listed in the October 25, 1996 issue of Standards Action with the following scope: Covers the fire safety aspects of industrial trucks with internal-combustion engines, such as tractors, platform-lift trucks, fork-lift trucks, and other specialized vehicles for industrial use. These requirements do not cover other possible safety aspects of such equipment. These requirements do not cover farm or road vehicles or automotive vehicles for highway use. Internal-combustion engine-powered industrial trucks covered by these requirements are identified as follows: Types G, D, LP, and G/LP - Trucks fueled with gasoline (G), diesel fuel (D), liquefied petroleum gas (LP), or either gasoline or liquefied petroleum gas (G/LP), having fuel, electrical, and exhaust systems provided with minimum acceptable fire safeguards. Types GS, DS, LPS, and GS/LPS - Turcks fueled with gasoline (GS), diesel fuel (DS), or liquefied petroleum gas (LPS), or either gasoline or liquefied petroleum gas (GS/LPS), provided with safeguards in addition to those required for Types G, D, LP, and G/LP. Type DY - Trucks fueled with diesel fuel (DY), provided with all safeguards required for Type DS, without any electrical equipment, including ignition equipment, and equipped with temperature limitation features. As a result of the canvass of BSR/UL 558 that was announced in Standards Action on October 25, 1996, substantive revisions have occurred:
