Kenny explained it to me like this. Crude oil puts of a gas called HTC that is highly explosive. The oil itself is flammable but not explosive. They were working, probably circulating the oil. I guess it does something to the quality of it. These kids work for the guy who owns the oil, then Kenny works for Cenex and they test the oil for quality and decided whether or not to buy it. The first guess was maybe the kid on the top of the tank was smoking, but our "extra kid" Huck knows him and said he chews instead. One of Kennys coworkers showed up here yesterday and they were talking about it. I guess if the conditions are just right, still air, just enough HTC, that static electricity can cause it to explode. Kenny and the guys are warned of this and are all trained to handle or help in this type of situation. It can happen to any of them at anytime. You girls remember a while back I was complaining about Kenny starting school? Well I am thinking it may be high time for a career change. Reality bites!
