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

Dear Mr. Lucas:

This is in response to your letter of September 6, 1991, requesting compliance determinations for your three new locking hooks.

As you recognize in your letter, the Occupational Safety and Health Administration does not approve nor endorse products. The variable working conditions at jobsites and possible alterations or misapplication of an otherwise safe product could easily create a hazardous condition beyond the control of the manufacturer. However, we have reviewed the product data enclosed with your letter and it appears that if the Shur-Loc Hook, locking flapper latch and lock latch with sliding latch bar are properly installed and locked, the user would be in compliance with 29 CFR 1926.550(g)(4)(iv)(B).

If we can be of any further assistance, please contact Roy Gurnham or Dale Cavanaugh at (202) 523-8124.
