ANSI/ASSE A10.28-1998 (R2004)– BACKGROUND MATERIALS

< Back

ASSE, as secretariat of the A10 ANSI Accredited Standards Committee (ASC) for Construction and Demolition Operations, has continued to receive a number of inquiries related to ANSI/ASSE A10.28-1998(R2004) Safety Requirements for Work Platforms Suspended from Cranes or Derricks.

Due to these inquiries, we have put together a “guide” for those with interest.

Title: Safety Requirements for Work Platforms Suspended from Cranes or Derricks

Scope: 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. Safe use of such equipment depends on the user following all provisions contained herein. A competent person shall perform a job analysis on all equipment to be used to suspend platforms from cranes and derricks, including the platforms. A copy of the job analysis shall be maintained at the jobsite.

Past Version of the Standard:

A10.28-1992

ANSI approved the standard on June 23, 2004.
