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.

Dear Mr. Helmreich:
This is in response to your letter of September 25, requesting a clarification of 29 CFR 1926.451 concerning the intermingling of scaffolding components.
This further confirms that the Occupational Safety and Health standards for scaffolds do not prohibit the intermingling of scaffolding components manufactured by two different companies. However, the resulting scaffold must comply with all of the applicable regulations when used by employers, including those of subsections (a) general provisions, (c) - tube and coupler scaffolds, and subsection (d) - tubular welded frame scaffolds.
If we can be of further assistance, please let us know.
John B. Miles, Jr., Director
Directorate of Field Operations
