OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov.

|MEMORANDUM FOR:||JAMES J. CONCANNON
DIRECTOR, OFFICE OF VARIANCE DETERMINATION
|THROUGH:||DONALD A. SHAY
DIRECTOR, OFFICE OF COMPLIANCE PROGRAMMING
|FROM:||JOHN K. BARTO
CHIEF, DIVISION OF OCCUPATIONAL SAFETY PROGRAMMING
|SUBJECT:||Clarification of Scope of 29 CFR 1910.66|
29 CFR 1910.66 (Power Platforms for Exterior Building Maintenance) would require an employer to apply for a variance if the employer desired to ground rig a powered platform for exterior building maintenance on a building where the platform has a rise of greater than 130 feet. However, 29 CFR 1910.28 (Safety Requirements for Scaffolding) does allow ground rigging of two-point suspension scaffold platforms used with hoisting machines for maintenance of buildings and structures.
