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, installed, or used primarily for the movement of people. This Standard does, however, apply to certain conveying devices that incorporate within their supporting structure workstations or operator's stations specifically designed for authorized operating personnel.
