This is going to be a bumpy road, he will be in a hospital for two months or so, will undergo a number of medical procedures, some buddies of him will have even to get a skin graft.   It will take a month or two of treatment, depending of the body reaction.

    Anyway he was lucky, somewhat he didn´t had the full blast despite being a snack in front of the bottle, at a certain distance.

    I´ll be around when I can, it´s being a hectic pace, I have to be going back and forth all the time.  Thanks you all.
