OSHA said the described buildings fell under the general-purpose public warehouse provision. It explained that “public” in the title did not change the classification.

Dear Mr. Dalbke:

This is in response to your letter of December 18, 1975, regarding a classification of your warehouses in which Class 1A and Class 1B liquids are stored.

The Occupational Safety and Health Administration (OSHA) would classify your warehouses as general purpose public warehouses. This classification is based on the information you furnished, that you are a wholesale distributor, that your warehouses are not accessible to customers or the public, nor do you share facilities with other companies.

29 CFR 1910.106(d)(5)(v) General Purpose Public Warehouses, would apply to these type warehouses. The word "public" in the title of this section has no real significance. It is planned to revise the title in line with the new title in the 1975 NFPA National Fire Codes (Section 30-4470 of "General Purpose or Industrial Plant Warehouses."

If I may be of any further assistance, please contact me.

Sincerely,
John K. Barto, Chief
Division of Occupational Safety Programming
