(d) the personnel lift authorizer to only authorize personnel lifting over, under, or in the vicinity of power lines, in accordance with the requirements of Mandatory Appendix I.
(e) personnel platforms not to be used in winds in excess of 20 mph (32.2 km/h) at the hoisted platform height, electric storms, or other adverse weather conditions that could affect the safety of personnel.
(f) the lift director to verify that each of the requirements in this Section have been met.
(g) the lift director to hold a pre-lift briefing attended by the hoisting equipment operator, platform occupants, and ground crew If individuals are changed during a series of personnel lifts, each new person shall be appropriately briefed by the lift director. Contents of the briefing shall, as a minimum, cover
(1) the operations section of this Volume
(2) assignment and responsibilities of each person involved in the lift operation
(3) the procedures to be followed
(4) guidance on general and specific safety precautions
(5) special signals for the operation
(6) unique considerations of the lift
(7) work to be accomplished during lift
(8) emergency procedures for the loss of power, control, or other system faults
(9) if applicable, the responsibilities and assignments contained in Mandatory Appendix I when lifting personnel near electrical power lines
(h) the lift director to terminate personnel lifting operations if hazardous conditions develop during the lift.
(i) personnel platforms to be only used for personnel, their tools, and sufficient material to do their work. They shall not be used for solely transporting bulk materials.
a qualified person to evaluate the safety concerns of the operational environment and verify the platform and hoisting equipment are suitable for use. Additionally, special work circumstances may require further precautions. Precautions such as, but not limited to, the following shall be taken:
(1) When welding is to be accomplished from the personnel platform, suitable electrode holders shall be provided to protect them from contact with any conducting components of the platform.
(2) lift director shall instruct operators of hoisting equipment, installed on floating vessels, not to lift personnel when the list or trim of the vessel exceeds 5 deg or the limits of the manufacturer’s load chart. Wave action and vessel-to-vessel motions shall be taken into consideration.
(3) When personnel lifts are conducted over water, personal flotation devices shall be provided and required to be worn. A personal fall arrest harness shall be worn and shall be attached to the platform manufacturer’s anchorage point while personnel are lifted over land and detached while personnel are lifted over water.
(4) A boat with appropriate rescue personnel shall be available at all times during a personnel lift over water.
(5) Appropriate personnel protective equipment shall be provided and required to be used around toxic, flammable, or hazardous substances or fumes.
(6) Any concentrated loading of the platform shall be reviewed to preclude the overstressing of any component or impairing the platform stability.
(7) Where the rotation of the platform, while hoisted, can create a hazard, appropriate restraining methods shall be provided and required to be used.
23-3.2.2 Hoisting Equipment Operator
(a) The hoist equipment and platform manufacturer’s information shall be consulted for specific instruction on the equipment operation. The hoisting equipment and platform operation instructions in this Volume are intended as minimum criteria for general applications.
(b) The operator should avoid the simultaneous operation of more than one of the hoisting equipment motion controls, unless such practice increases the safety of the lift operation.
(c) The operator shall
(1) inspect the hoist equipment setup area before the personnel lift and report his observations to the lift director. The operator shall inspect the area for potential hazards, such as but not limited to
(-a) excessive load and/or radius
(-b) overhead obstructions and electrical transmission lines.
