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.

With regard to Mr. Charles Deckard's request of July 9, 1974, I submit the following.

The above subject standard applies only to the specific derricks indicated and to any modification of those derricks that retain basic features as those listed in 29 CFR 1910.181(b)(1). The fundamental features applicable to these derricks are also illustrated in this section.

A standard oil well derrick, not fitting these characteristics, is not covered by 29 CFR 1910.181.
