This Standard applies to the design, construction, installation, maintenance, inspection, and operation of conveyors and conveying systems in relation to hazards. The conveyors may be of the bulk material, package, or unit handling types where the installation is designed for permanent, temporary, or portable operation. This Standard shall apply, with the exceptions noted below, to all conveyor installations. This Standard specifically excludes any conveyor designed for, installed for, or used primarily for the movement of human beings. This Standard does, however, apply to certain conveying devices that incorporate within their supporting structure work stations or operators stations specifically designed for authorized operating personnel. This Standard does not apply to conveyors such as underground mine conveyors for which specific standards are already in effect, or to equipment such as industrial trucks, tractors, trailers, automatic guided vehicles, tiering machines (except pallet load tierers), cranes, hoists, power shovels, power scoops, bucket drag lines, trenchers, platform elevators designed to carry passengers or an operator, manlifts, movingwalks, moving stairways (escalators), highway or railroad vehicles, cableways, tramways, dumbwaiters, pneumatic conveyors, robots, or integral machine transfer devices. Some of the foregoing have specific standards. The provisions of this Standard shall apply to equipment installed one year after the date of issuance.
