There are very few organizations out there that have as much dedication and passion than the group at the Firefighter Rescue Survey. This survey was developed a few years ago and has been tracking our "wins" for the last few years. To date there's over 1,000 plus recorded saves to show in the data. Currently, NFIRS (which technically isn't a requirement either) is used to track almost all of our losses. There's a tab in their reporting asking if there was a civilian death or a civilian injury. However, there's no question at all if there was a save. The closest that you can come in your reporting to any of this is by putting down "Search & Rescue" as a task. USFA additionally holds data on civilian fire deaths, but we are still trying to find where they exactly collect that data.
Just a few months ago, the group started a Facebook Group with the intent that others from around the world could chime in on rescues they heard, saw, or performed. This group in a few short months is just shy of 5,000 members with nearly half a dozen articles shared per day. Sadly, the numbers on the Facebook Group equate to a very high success rate of Search and Rescue but those numbers just aren't be added into the physical survey.

One of the most important things that this information does is it drives our training and tactics. By using the data we can tell where a high percentage of victims are found during different times of the day, age appropriate tactics, and more. This survey is an excellent source for any Search & Rescue material you are looking for as far as data.
Make sure you check out the survey and help push documentation of saves that you know of.
