How should I prepare for a field study and what should I do if there's an accident?

I just need help answering the last part because I cant seem to find a answer anywhere.

How you plan for an accident depends upon the location of your field study. It will make a difference whether you're doing a field study in a desert of jungle or whether you're doing it in a hospital of university.
