 They come to the rescue at times when we need them most. First responders are making enormous personal sacrifices to keep showing up for us and fighting the good fight. Nearly 70% of all firefighters are volunteers. That means when they get injured or quarantined, they may not have a way to pay their rent or keep their families safe and fed. No matter who you are or where you live, when you call 911 and ask for help, first responders show up.
