I don't know what kind of situation he is in, but I carry a jump kit in my truck because as a volunteer FF/EMR, I don't know when I will need the medical supplies. It seems like some of the people on here are dead set against the idea of carrying your own kit. I agree that if your not on duty you may not be under med control but I also know that if I am in my county and wearing a dept t shirt (volunteer dept)I'm on duty and if something were to happen I would much rather have my bag than nothing at all. Also a suggestion, I found out on a call the other day that it is important to have both an adult size bp cuff as well as an infant cuff. Good luck with EMT class, I will be going myself in a few months.
