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.

Secretary
Southern Pine Inspection Bureau

Pensacola, Florida 32504

Dear Mr. Jones:

This is in response to your letter of October 22, 1981, concerning the use of Southern Yellow Pine versus the use of Douglas Fir.

Please be advised that we no longer specify what species of wood should be used for speciality system designed scaffolding. Instead, when the plank span is extended to 10' 6" the planks must be rough full-dimensioned 2" x 12' planks of Dense Select Structural Grade or equivalent.

I hope this explanation will answer your question. If I can be of further assistance, please contact my office at (202) 523-7144.

Sincerely,



James J. Concannon
Director
Office of Variance Determination
