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. Scruggs:

This is in response to your May 14 letter requesting an interpretation of an Occupational Safety and Health (OSHA) standard addressing the use of head protection at construction sites. I apologize for the delay in responding to your inquiry.

As you know, sections 1926.100(a) and (b) require employees to be protected by protective helmets that meet the specifications of the American National Standards Institute (ANSI) standard Z89.1, 1969, Safety Requirements for Industrial Head Protection. Because ANSI only tests and certifies hard hats to be worn with the bill foreword, hard hats worn with the bill to the rear would not be considered reliable protection and would not meet the requirements of 29 CFR 1926.100(a) and (b) unless the hard hat manufacturer certifies that this practice meets the ANSI Z89.1- 1969 requirements.

If we can be of any further assistance, please contact Mr. Roy F. Gurnham or Mr. Dale R. Cavanaugh of my staff in the Office of Construction and Maritime Compliance Assistance at (202) 523- 8136.
