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. Conklin:
Assistant Secretary Bingham has requested that I respond to your inquiry requesting approval for sewer maintenance rehabilitation workers to wear bump caps instead of helmets per ANSI Z89.1.
Employees entering sewer manholes to clean sewers, set up TV and repair equipment, etc., are subject to probable head injuries indicated in your letter. Therefore 29 CFR 1910.135 and 29 CFR 1926.100 require that helmets meeting the requirements and specifications established in the American National Standard Safety Requirements for Industrial Head Protection Z89.1-1969 be worn for the protection of employees. Although there is a minimal chance of head injury from falling objects, employees are exposed to bumps, cuts and scalp injuries while working in manholes. Bump caps would not provide adequate employee head protection for all exposures in manholes because they are not constructed in a manner to provide the protection required.
If you have additional questions concerning OSHA safety and health standards you may wish to contact our Tampa Area Office. The address and telephone number of that office follow:
