Well, it wasn't enough to get emergency responders and Good Samaritans leery of helping people in vehicles because they might be playing possum and then try to rob ya. Now, people should wait until the haz-mat team arrives before opening car doors.
Want to know why? It's because people are killing themselves in new and more inventive ways, and you might just die as well if you don't have the proper gear. I think of all the diabetics and heart attack victims who won't be saved in time now, but we really do need to keep the EMTs safe. Hopefully with more gear and more training, your average EMT would be able to help you whether chemicals were suspected or not.
