Staff incident investigators with the US Chemical Safety Board are looking for editions 1-3 of the American Petroleum Institute publication entitled: Refinery Inspection Areas of Vulnerability (no document number). They have access to the 4th edition, 1991, which is available online. A historical overview of this document is needed to determine the first description of low silicon as a vulnerability to corrosion in refinery piping.


There are no holdings in OCLC. The Technical Reports and Standards Division of the Library of Congress does not have this document. I am waiting for a response from the API Library but wanted to make a broader sweep in case any other library has this publication.



Thank you in advance for your assistance.
