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.

June 10, 1983

Mr. Bruce Bair
Vice President
Lincoln Ladders Manufacturing Company, Inc.
909 Baltimore Boulevard
Westminister, Maryland 21157

Dear Mr. Bair:

This is in response to your letter of May 18, 1983, concerning your desire to advertise a new aluminum ladder jack as meeting OSHA requirements. This also confirms your conversation with Mr. Simms of my staff on May 26, 1983, in which you verified that the ladder jack's bearing area is at least 10 inches.

We have thoroughly reviewed your aluminum ladder jack, and it appears to meet the intent of the applicable OSHA standards 29 CFR 1910.28(q) and [29 CFR 1926.452(k)(3)]. However, OSHA does not approve or endorse products for the following reasons:

  1. Alteration or misapplication of an otherwise safe piece of equipment could easily create a hazardous condition beyond the control of the manufacturer.

  2. The variable working conditions at job sites.
If we can be of further assistance, please let us know.


Bruce Hillenbrand, Acting Director
Federal Compliance and State Programs
