Crane (mobile) footing is adequate.2. System controls and safety devices areactivated and functioning properly.3. No interferences exist.4. Configuration necessary to reach worklocations will allow the crane to remain under 50percent ofrated capacity.NOTE: Materials and tools to beused during theaetuallift, ifsecured to prevent displacement, canbe in the platformfor the test lift.NOTE: A single trial lift may be performed for alllocations to be reached from a single setupposition.h. The trial lift shall be repeated prior tohoisting employees whenever:1. The crane (mobile) travels or is movedand set up in a new location or returned to apreviously used location.2. The lift route is changed, unless theoperator determines that the safety ofthe hoistedpersonnel is not affected.i. A visual inspection ofthe crane, rigging, andpersonnel platform shall be conducted by aqualified inspector immediately after the trial lift,prior to lifting personnel. Any defects found thatcreate a safety hazard shall be corrected prior tohoisting personnel.j. Mter the trial lift and just before hoistingpersonnel, the platform shall be lifted a few inchesand inspected to ensure that it is secure andproperly balanced. Personnel shall not be hoistedunless the following conditions exist:1. Hoist ropes are free ofkinks.2. Multiple-part lines are not twistedaround each other.3. The primary attachment is centeredover the platform.4. Ropes are properly seated on drumsand sheaves.k. These special procedures shall be followedwhen lifting personnel:1. The crane shall be inspected dailyprior to lifting personnel, in accordance with therequirements for frequent inspections for the typeofequipment being used.2. Thelifting and supporting shall bemade under controlled conditions and under thedirection ofa designated leader. A qualifiedsignaler shall be appointed.3. Prior to each working shift, thepersonnel lift platform and rigging shall beinspected.4. Communications between the craneoperator, signaler, and persons being lifted shallbe maintained throughout the lift.5. The employees being hoisted, moved,or positioned shall remain in continuous sight of,and in direct communication with, the operator orsignaler. In situations where direct visual contactwith the operator is not possible and the use ofasignaler would create a hazard for that person,direct communication alone (such as two-wayradio) may be used.6. Tag lines shall be used unless their usecreates an unsafe condition.7. The crane shall be operated so thatlowering will be power-controlled (no free-fall).8. When welding is done bypersonnelfrom the platform or basket, the electrode holdersshall be protected from contact with metalcomponents ofthe personnel platform orbasket.9. Employees working from a platformshall wear body belts/harnesses with lanyardsattached to the lower load block or overhaul ball,or to a structural member within the platform thatis capable ofsupporting a fall impact. Whenworking above water, the requirements of29 CFR1926.106 (Occupational Safety and HealthRegulations for Construction) shall also apply.10. The operator shall remain at thecontrols when the personnel platform is occupied.11.
