Dear Mr. Torres:

This is in response to your request concerning OSHA standards on the minimum size of the access to tanks or pressure vessels. This also confirms a conversation on the subject matter with Mr. Pete Wasko, a member of my staff.

In brief, there are no specific OSHA standards on the minimum size of the access to tanks or pressure vessels beyond the requirements of acceptable good standards of design, such, as may be indicated in the ASME, API, or UL code under which they may have been built as mentioned in such OSHA standards as 29 CFR 1910.106 (b)(l)(iii)(a); 1910.106(b)(l)(iv)(b); 1910.106 (b)(l)(v)(b); 1910.169(a)(2)(i). Copies of these standards are enclosed.

Should you need any further assistance, please feel free to call or write.

Sincerely,



Grover C. Wrenn Director,
Federal Compliance and State Programs
