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 http://www.osha.gov.

Dear Mr. Grace:
This is in response to your letter of July 24, requesting clarification of 29 CFR 1926.550(b)(2) as it relates to the point of instability of a crane.
As discussed with you in a telephone conversation with a member of my staff, any "breakaway" of the outrigger would place the crane from stability to point of instability. We have coordinated this answer with the State of Arizona Division of Occupational Safety and Health.
If we can be of further assistance, please contact us again.
John B. Miles, Jr., Director
Directorate of Field Operations
