300 Plus Abbreviations & Acronyms Every Firefighter Should Know
In the fire service, we enjoy using abbreviations and acronyms for things. Some fire service personnel tend to go a bit overboard when talking, by using too much "alphabet soup." I'm not providing this information to encourage you to use more abbreviations in your everyday life. I'm providing this information to educate you and better prepare you for talking with fire service personnel or reading fire service (yes, like it or not, EMS is also fire related) textbooks or publications. Knowledge is power and the more you know, the better off you are.
Communications are a problem everywhere, and in the fire service, we have our share of communication problems. In the fire service, we try not to pattern ourselves after our law enforcement counterparts and use "9 or 10-codes" when talking. We are expected to use clear text when talking, to ensure the sender understands our message. Have you ever heard someone talk and you only comprehended a fraction of what they said? For example, have you ever heard a fire service official (such as a Public Information Officer) say something to the effect of "the first rig got on scene and found they had a TC with a couple of DOA's and a suspect that was GOA. They were UTL any live patients?" I bet you have. You may (or may not) know what they are saying, and the public probably has less of a clue as to what they were saying.
Before we go any further, remember that abbreviations should be used sparingly, if not at all. A rule of thumb I try and follow is to only use abbreviations that the average person would understand. There are only two of the abbreviations listed below that fall into that category - CPR and EMT. Those two terms are widely used and understood by the general public. The rest of the terms are foreign to the public and even to some fire personnel. If you do use abbreviations when documenting information on a patient care report (if you are an EMS provider), make sure the abbreviations are approved by the county. Some abbreviations such as PE may have many meanings, all meaning something slightly different (pulmonary embolus, pulmonary edema, physical exam - see what I mean?). Abbreviations can get you in trouble if you're not careful. As a company or chief officer documenting their actions after the incident in a formal, legal report, I encourage people to not use any abbreviations because of the possibility of more than one meaning.
The last thing you want to do is have to clarify to a judge, jury and questioning attorney all of the abbreviations within your report, especially ones that have multiple meanings. I can hear the attorney now "so, Captain Prziborowski - you listed that the patient had suffered a PE. What exactly is that abbreviation? Is it possible there are multiple meanings for that abbreviation? If so, how can we be sure that is what you meant to document? We cannot." Had I just wrote out Pulmonary Embolus, I would have been ok and we would not have dwelled on that subject and I wouldn't have looked like someone less than professional trying to justify why I did what I did.
If you ever find yourself answering questions to an oral board (for entry-level or promotional examinations), please shy away from using abbreviations. While you may think that the fire personnel rating you understand the abbreviations, you can't be too sure. Also, many oral panels have a citizen from the community someone outside of the fire service on the panel as a rater (someone from personnel/human resources, etc.). Using abbreviations may actually hurt you, especially if they do not understand what you are trying to say. The same goes for resumes and job applications; keep the abbreviations to a minimum. About the only other abbreviations I can think of that may be ok (besides CPR or EMT) would be a two-digit state abbreviation (CA, AZ, etc.) or maybe the suffix to an address (Ave., Blvd., St., etc.).

Note: Depending on the area of the country you are in, the above abbreviations may slightly differ. If you decide to use those in your documentation, ensure they are accepted or abbreviations in your part of the country.
Abbreviations specific to the state of California:
- CAL OSHA (California Occupational Safety and Health Administration)
- CCAI (California Conference of Arson Investigators)
- CCR (California Code of Regulations)
- CDF (California Department of Forestry)
- CFFJAC (California Fire Fighter Joint Apprenticeship Committee)
- CFCA (California Fire Chiefs Association)
- CFMA (California Fire Mechanics Association)
- CHP (California Highway Patrol)
- CPF (California Professional Firefighters)
- CSFA (California State Firefighters Association)
- CSFM (California State Fire Marshal)
- CSTI (California Specialized Training Institute)
- LAFD (Los Angeles Fire Department)
- NOR CAL TOs (Northern California Training Officers Association)
- PERS (Public Employees Retirement System)
- SBFS (State Board of Fire Services)
- SFFD (San Francisco Fire Department)
- SFPA (San Francisco Paramedic Association)
- SO CAL TOs (Southern California Training Officers Association)
Note: I added the California abbreviations not because I live in California, but to make those that live in California aware of those resources but also to direct folks living outside of California to look up similar organizations within their state which probably have similar abbreviations.
You may or may not have heard of the above abbreviations. If you have not heard any of those, now you can say you have learned something new today. If you are not sure of what each term means, take the time to do some research and find out their meanings. Why are abbreviations so important when we are supposed to be practicing "clear-text" in our communications? Because there are certain situations when abbreviations may be necessary, however that is very rare.
More importantly, it is important to understand abbreviations so when others say them during a conversation or in a written form of communication, you don't have to look like you are ignorant or uneducated about what they are talking about. Be careful though - try to not use abbreviations when talking to members of the public, especially if you ever find yourself on camera or doing a station tour or public education demonstration. The public probably does not know what you are talking about and you will lose credibility and also lose your audience and they will eventually not pay attention or comprehend what you are talking about.
I have read or heard all of the abbreviations I mentioned over the years. A vehicle accident in Southern California is a "TC" while a vehicle accident in some Northern California departments is an "MVA." While they both mean the same thing, they may mean something different to someone. Keep it simple, use clear-text as much as possible, and your intended message will be communicated effectively and efficiently. Knowing abbreviations will help allow you to better perform your job and understand what is occurring in your fire service.
For those of you wondering why I included so many EMS related abbreviations, if you have not figured it out yet, EMS is here to stay - like it or not. Most fire departments nationwide and fire service personnel have embraced EMS and come to the conclusion that EMS is not only the right thing to do because of our resource availability and the strategic locations of fire stations, but it is the right thing to do because we are here to help people have a better day. When people call 9-1-1 for any type of assistance, I want them to feel like they can call the fire department and know that we will either solve their problem or point them in the direction and get them the correct assistance they need if we cannot provide it. Since most fire departments are providing some form of EMS in their daily life, that means they will either employee EMTs or paramedics, and also deal with other EMT's or paramedics from assisting agencies on a regular basis. Understanding the language you will be hearing (a lot of abbreviations, especially when talking between each other) will make you understand more about what is going on.
The next time you find yourself watching "ER" or "Emergency (Squad 51, you know - Johnny and Roy)", you will be able to better understand what they are saying.
