Nokia battery charger recall

    Recently Nokia recalls 14m battery charger due to risk of electrical shock
    in use. Probably, it is another scarey case following Sony battery pack
    explosion in notebook computers. Nowadays, every home may have more than a
    dozen of mains adapters/battery chargers. I searched those models and it
    appears the two halves of housing are fixed by two screws. How come it will
    separate touching the live parts? Do anyone know or experience such case
    and willing to share the knowledge?

    Thanks,

    Scott

    If it's anything like most recalls, it's probably some extremely rare
    case where someone misusing it could get a shock and sue them so they
    recall them instead.

    While technically feasible, I would worry more about stepping out of my
    house and getting hit by lightning than electrocuted by a cellphone
    charger. In any house there are dozens of things that *could*
    potentially hurt you or start a fire, thankfully it's exceptionally rare
    that it actually happens without some help.

    If it does happen, as an engineer we have to understand the cause and find a
    way to prevent from it. The luck will not be with you all the time!

    Of course, I'm just saying that a recall of one charger doesn't mean one
    should be worried about using others.

    If such mistake can be shared, I believe that is very useful material for
    training new engineers avoiding such mistakes. I am eager to learn about
    such mistakes too.
