Dear Mr. Strachan:

This is in response to your letter of July 19 to the Occupational Safety and Health Administration (OSHA) in which you request an interpretation of the OSHA regulations covering the use of crane or derrick suspended personnel platforms (CDSPP) during stack and chimney erection.

After reviewing all of the information submitted with your request, we find that you have met the intent of 29 CFR 1926.550(g)(2) and agree that the use of CDSPP is acceptable for all activities related to the erection of stacks and chimneys above the 100 foot level. Of course, all other provisions of paragraph .550(g) still apply.

If you have any further questions on this matter, please contact me or Mr. Dale Cavanaugh of my staff at (202) 219-8136.

Sincerely,



Roy F. Gurnham, P.E., J.D.
Director
Office of Construction and Maritime
Assistance
