Subject: 2011 Hazmat Events summary
X-To: dchas-l**At_Symbol_Here**med.cornell.edu
I've put together a statistical overview of the hazmat events that I've sent to the list over the year (1869 items). The percentages generated for location, economic sector, type of event, extent of event and chemical identity are similar to those previous summaries I've sent to the list.
The biggest difference is that I've agglomerated a variety of smaller sectors into "public", including home events, hospital responses, retail settings, illegal activities, etc, because these events were the most ambiguous to determine and their numbers are small enough that maintaining those distinctions didn't add much value to the breakdowns. What they have in common is that they are non-transportation settings where the general public is likely to be present.
In addition to the general overview, I've done a similar breakdown for lab events (148 items); the general percentages in the lab events are remarkably similar to the larger hazmat response universe.
If anyone would like Excel spreadsheets with a list of the individual headlines, let me know. You can still review the information available about the events at

Let me know if you have any questions about this.
