the temptation to borrow emergency equipment is so strong. we were at the firehouse one time and the power went out. at the time the station didn't have a generator but on the trucks we carry a total of 3 of them. we never even considered taking them off...we got one from my house instead. emergency supplies are so HANDY but it's imperative to maintain a state of readiness. that said, don't wait for a nuclear war to take a band-aid out of your kit. I often use the kit in the car for tiny emergencies like skinned knees and bug bites. just restock asap. and never loan out your kit
