Nokia battery charger recall

[Scott]

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.
