Personnel Lifting Platforms
WAC 296-882-100
Scope
This rule applies to the lifting, lowering, and transporting of personnel
using personnel platforms connected to cranes or derricks.
Personnel platforms can be either suspended from the crane or derrick by
wire rope or chain, or attached to the boom of the crane or derrick. Using
articulating boom cranes with suspended platforms is not allowed
Important!
 Do not use cranes or derricks for personnel lifting when there is a
less hazardous way to accomplish the work.
Cranes and derricks are designed and intended for material
handling, and are not required to meet the same design
standards as manlifts, aerial lifts, bucket trucks, and other
conventional personnel-lifting equipment.
The lifting or lowering of personnel using material handling cranes
and derricks is prohibited unless all of the applicable
requirements of WACs 296-882-100 through 296-882-60030 are
met.
ASME B23-0.1
Within the general scope defined in Section I, ASME B30.23 may apply
to hoisting equipment covered within certain volumes of the ASME
B30 standard, that is used to lift, lower, or transport personnel in a
platform, by wire rope or chain, from hoist equipment, 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 volume addressing the hoisting
equipment to be used shall be consulted for the applicability of the
ASME B30.23 volume.
Section 23-0.2: Intent of ASME B30.23
The intent of this volume is to establish minimum design criteria,
equipment features, and operational procedures for using material
hoisting equipment to lift personnel. Use of this volume will not raise the
level of safety of the material hoisting equipment to that obtained by
using equipment specifically designed and manufactured for lifting
personnel. The ASME B30 standard hoisting equipment is designed
and intended for material handling and is not required to meet the same
design standards required of conventional personnel lifting equipment
(ANSI/SIA A 92 Aerial Platforms). Lifting and lowering of personnel
using ASME B30 Standard hoisting equipment shall be undertaken only
in circumstances when it is not possible to accomplish the task by less
hazardous means. Unless all of the applicable requirements of this
volume are met, the lifting or lowering of personnel using ASME B30
Standard equipment is prohibited.
