ok, I'll add my major one. Background: Our service uses a two person BLS crew and an ALS medic on a first response vehicle (usually an SUV), and fire is tiered to all unconscious, VSA, and seizure calls. If the ALS medic needs to attend the patient one of the BLS medics will drive the SUV to the hospital.
Went to a call for a seizure, that happened to occur in a factory. We are suppose to wear helmets for any industrial setting, the ALS medic got there seconds before us (no helmet), I asked my partner and he said don't worry about it (as we pass a big sign that says wear your helmet). We go inside and a guy had a seizure while standing over this large bin, the ALS medic asks me to go and grab the backboard and straps. So I grab a firefighter and off we go back to the vehicle. By the time we got back to the patient, he was awake and was going to climb out of the bin (c-spine ruled out). The ALS medic or my partner (I don't remember) asked me to just get the stretcher ready and to forget about the backboard. I don't remember who was carrying the backboard, but it got leaned against another large bin. So I lower the stretcher by myself and start to get the sheets ready while everyone else is watching the patient climb out of this bin (3 firefighters, 1 chief, my partner, ALS medic and about 3-4 workers). So I flick the sheets open and the backboard falls (no one near it) and smacks me in the right temple then clatters to the ground. No one saw it happen so everyone turns around, and I'm just standing there partially stunned. My partner (or the ALS medic - don't remember) ask me if that hit me, I think I was able to mumble something about yes it hit me but I was ok. So we load up the patient and *I* drive the ambulance to the hospital, all the while thinking that I should hold my foot a certain way so that if I pass out I wouldn't be pressing on the gas. In hindsight, this was probably not a good idea... We get to the hospital and I have a killer headache, so call the supervisor and he's unreachable, so I had to explain to dispatch why I couldn't work anymore (and they and I are laughing) and they got a hold of the supervisor for me. Do the doctor thing, told no more working for that night. The doctor said to just have someone make sure I woke up easily the next morning. Did I mention that this happened on Dec 30th 2004? The supervisor drove me home, luckily my mom was staying with me cuz of the holidays. The next morning I wake up with a very very bad headache, I can hear my mom on the phone with my dad and ask her to grab me an ice pack. As she was coming up the stairs to hand it to me, I felt woozy then next thing I remember is my mom saying "Dear, dear, I have to go I have to call 911". I wake up and I'm lying on the floor about 4 feet from where I was standing. My mom asked me if I still wanted her to call. So she calls...panicking, and I'm trying to tell her what to say. I spent 7 hours in emerg under observation, CT Scan came back negative and I was discharged with instructions to not drive for 7 days, and to F/U in 7 days. I don't really remember anything about new year's eve or new year's day that year.
I got in trouble with my management for not wearing my helmet. I argued that it wasn't a piece of machinery that hit me it was my own equipment, and it could have happened anywhere including in someones house. No go, still got a note to file.
Lesson learned - Wear helmet.
