ASME B20.1-2009

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.

B20.1 offers essential guidance for safety to both public and private sectors:

• For public sectors, it serves as the basis for state, municipal, and other jurisdictional authorities in drafting regulations governing the design, constructions, installation, maintenance, inspection and operation of conveyors and related equipment.
• For private sectors, B20.1 provides a standard reference of safety requirements for owners/users, manufacturers, installers, insurance companies, distributors, and designers
