Description

B20.1 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 operator’s stations specifically designed for authorized operating personnel.
