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.

Subject: 29 CFR 1910.217(c)(5), Additional Requirements for Safeguarding, Typographical Errors.

Typographical errors which have existed in the above referenced standard since its original issue, have created some misunderstanding as to its meaning.

The phrase "...in the point of operation, and a two-hand control, presence sensing device of Type B gate or movable barrier...", will be corrected by the Office of Standards Development in the next change in the 1910 standards and in the Federal Register by adding a comma after the word device and deleting the word "of" before the word "Type." The phrase will then read "...in the point of operation, and a two-hand control, presence sensing device, Type B gate or movable barrier..."

This information should be distributed to all field personnel and interested parties.
