scope:

This standard applies to platforms suspended from the load lines of cranes or derricks in order to (1) perform work at elevations that cannot normally be reached by other types of scaffolds or aerial work platforms or (2) transport personnel to elevations where other means of access are unsafe or impractical because of design or worksite conditions.

1.1 Application. This standard shall apply to platforms suspended from the load lines of cranes or derricks in order to: 1) perform work at elevations that cannot normally be reached by other types of scaffolds or aerial work platforms, or 2) transport personnel to elevations where other means of access are unsafe or impractical because of design or worksite conditions. Safe use of such equipment is dependent upon the user following all provisions contained herein.

1.2 General Requirements. The use of a crane or derrick to hoist employees on a personnel platform is prohibited, except when the erection, use, and dismantling by conventional means, of reaching the worksite would be more hazardous or is not possible because of structural design or worksite conditions. Conventional means are considered to be such means as a personnel hoist, ladder, stairway, aerial lift, elevating work platform, or scaffold. A competent person shall perform a job safety analysis (JSA) on all equipment to be used to suspend platforms from cranes and derricks including the platforms. A copy of the JSA shall be maintained at the jobsite.

1.3 Exclusion. This standard shall not apply to platforms that are welded, bolted, pinned, or otherwise directly attached to a crane boom.
