Note: there won't be anything in the library specifically about groupthink and fire departments: no one has published that kind of research yet, at least not in journals that appear in the library databases.

Then you can take that info and show how it applies to a fire department situation.
Using Google
A Google search like this:
groupthink fire department
does bring up a number of resources about fire departments and groupthink, cognitive bias, etc.
When you want to use a website, just make sure it is trustworthy and authoritative. Here's a brief guide to evaluating websites.
