Crane Suspended Personnel Platform (MANBASKET) Permit

The use of a crane suspended personnel platform (manbasket) is prohibited unless there is no safer, practical, conventional means of access to an elevated work area. Ladders, scaffolds, stairways, aerial lifts and personnel hoists must be considered before using a crane to hoist personnel. If these options are more hazardous or not possible because of structural design or work site conditions, the hoisting of personnel from a crane is permitted only after written approval by the Contractor’s Senior Site Manager

Man baskets shall have a safe working capacity based on a minimum design safety factor of 5:1.
Factory manufactured manbaskets shall meet all applicable ASME fabrication specifications/requirements.
prior to certification by a Qualified Inspector . A proof-load test certificate shall be provided to the Qualified Inspector at the time of the initial certification inspection.

• An enclosed top that is high enough to allow personnel to stand upright, protect them from overhead hazards, and inhibits them from climbing out,
• Guardrail protection consisting of a top-rail approximately 1 meter (42 in) above the platform, a toe-board that extends at least 10 centimeters (4 in) above the platform, and a mid-rail midway between the top-rail and toe-board.
• All sides of the manbasket shall be enclosed between the top-rail and the toe-board with metal. If metal mesh is used, mesh openings shall not be larger than 1.3 centimeters (0.5 in),
• Suitable anchorage(s) inside the manbasket for securing personal fall-arrest equipment (full body harness/lanyards),
