Hi Cathy, 

There is probably not much available which could connect an ER with very useful data about a specific location involved in an incident during a response.  

Info on chemical storage is supposed to be provided to local emergency response officials at least annually in SARA Tier II reports.  Is someone from the hospital involved in the local emergency planning commission (LEPC)?  
This would probably have the most detailed chemical specific data.

For more general data you could try:
http://www.epa.gov/epahome/community.htm

For info about a community.  There are ways to drill down to specific facilities but data reported to EPA is generally limited to SARA 313 toxic reports, a much smaller subset than the Tier II reports.

It tries to consolidate data from multiple EPA programs.

Dear Colleagues:

Do databases exist that health care providers could access to determine the location of chemicals (storage/usage) in neighborhoods or linked with an address? =20

Please advise.
