Terminology and Abbreviations

I have combined the general fire department expressions, medical terminology, and abbreviations that I use throughout the book into this one chapter. This list contains definitions, explanations, and examples of usage of the terms that we regularly use on the fire department. They will be helpful for you to understand all of the things that I have written. It would have been too cumbersome and taken away from some of the stories if I had stopped to explain all of these terms when I used them. Since this list is both informative and descriptive, it’s even interesting to read it on its own.

I want to point out that general fire department terminology is a little different from one fire department to the next, especially in different parts of the United States.

Medical terminology in the list has been designated by “*MED” after the term.


Throughout the book, I have purposely used a lot of fire department terminology. I wanted to relate the stories in their natural form and for you to get a good taste of our terminology. After you finish reading this book, you will definitely have picked up and learned a lot of both fire department lingo and medical terminology. You may even start using some of the terms yourself.
