Chemical Transportation Incidents – Week of 11-22-25

Reporting Background

See this post for explanation, with the most recent update here (removed from paywall).

Data from PHMSA’s online database of transportation related chemical incidents that have been reported to the agency.

This is the second week where I have not had access to the PHMSA database to prepare this report. The web site continues (since December 12th) to display the same ‘explanation’:

“Hazmat Incident Report Search Tool
The ability to download pdf copies of incident filings or download complete datasets of the search results has been temporarily disabled. If you need pdf copies of incidents or relevant search criteria, please email relevant incident numbers to HMRequests@dot.gov.”

On December 12^th, I requested a copy of the database for the week of  November 8^th thru 14^th. I received two separate databases, but only one included all of the data that I have been using in this blog series. The other was just about twice as large, containing a number of additional data columns. In any case, I used the first to prepare my post on December 13^th.

Last week, I again requested a copy of database for the week of November 15^th thru 21^st, 2025. This time I received just the larger of the two DB copies. Assuming that the DB copy just included additional columns of information that was not in the smaller version, I tried to extract the same columns of information that I had been using, but was not able to do so. It appears that the smaller version may, in some instances, consolidate information found in multiple columns found in the larger DB copy.

This week, with the government on an extended Christmas holiday, I will not be requesting copies of the database for this week’s post. I will resume next week.
