Within the general scop e defined in B 3 0 Standard Introduction, Section I, ASME B30.23 may apply to hoisting and accessory equipment covered within certain volumes of the ASME B30 Standard, which is used to lift, lower, hold, or transport personnel inaplatform, bywirerope orchain, fromhoistequipment, or by a platform that is mounted on a boom of the hoist equipment. The lifting of personnel is not allowed using some ASME B30 Standard equipment. The ASME B30 Standard addressing the hoisting equipment to be used shall be consulted for the applicability of the ASME B30.23 volume.
This Volume establishes the design criteria, equipment characteristics, and operational procedures that are required when hoisting equipment within the scope of the ASME B30 Standard is used to lift personnel. Hoisting equipmentdefined bythe ASME B30 Standard is intended for material handling. Itis notdesigned, manufactured, or intended to meet the standards for personnel handling equipment, such as ANSI/SIA A92 (Aerial Platforms). The equipment and implementation requirements listed in this Volume are not the same as that established for using equipment specifically designed and manufac- tured for liftingpersonnel. Hoistingequipmentcomplying with the applicable volumes of the ASME B30 Standard shall not be used to lift or lower personnel unless there are no less hazardous alternatives to providing access to the area where work is to be performed. The lifting or lowering of personnel using ASME B30- compliant hoisting equipment is prohibited unless all ap- plicable requirements of this Volume have been met.

Aguardrailsystemmay include a means of access.ground crew: those individuals who are involved in the personnel lift, otherthan the hoistingequipmentoperator andplatformoccupants.Theseindividualsincluderiggers, signal persons, and supervision. handrail: a member supported on brackets to furnish support to platform occupants during lifting operations. hoisting equipment: a machine for lifting and lowering a loadand movingithorizontally. The machine maybe fixed or mobile and be driven manually, by power, or by a combination of both. As used in this Volume, the term covers all types of lifting machines addressed by the ap- plicable volumes of the ASME B30 Standard and used to lift, lower, or transport personnel.
