Not impossible...

You reach behind a desk to plug in your computer....your hand is on the base of the metal lamp on the desk...

Wrong!
A gfci trips only when the current on the hot wire does not match the current on the neutral wire.

Thinking of things as non-conductive will get you hurt or killed. Some items are less conductive than others, but how clean it is, what the moisture content is, and how much voltage you are dealing with all effect whether you might receive a shock.
Even the rubber or fiberglass tools/protective gear used by electrical workers must meet cleanliness standards to be considered safe to use.

This is all getting very tangential to the original question:

Will installing GFCI outlets throughout a house save his son's life?

And the answer is: In all practicality, it's just not likely to have an effect.

Thus, GFCIs are required in wet locations, i.e. kitchens, bars, bathrooms, basements, and outdoors where the operator is likely to be grounded either to the ground or operating a wet-zone appliance like a blender or toaster.

Of course you can engineer an unlikely situation of standing on one hand while using ones foot to open metal-clad drapes hanging on an iron rod that had a speaker wire draped over it which got pinched when someone stepped on them yanked the cord out of your stereo, only to have the other end fall in your fishtank at the same time that your ceiling fan broke loose, and dangled by its chain right into the same tank... while you were plugging in the vacuum - and touched the hot side... completing the ground, and tripping the GFCI.

BUT -- that's not what they're for. You can certainly put them in for a trivial increase in "safety" but if you mislead yourself to believe you are significnantly safer, you're just kidding yourself for the real risk of kids and outlets is that they don't understand them or believe they're dangerous, and so they experiment. Kids are much more likely to get hurt exploring an outlet than by the lack of a GFCI. So I would take the time not spent on replacing GFCIs throughout and spend that on outlet training instead.

The original purpose of GFI's was for wet areas since water and elec. don't play well together. I think to put them whole house would give you a false sense of safety. Really 2 is old enough to start teaching.

GFCI protection in a dry area is going to reduce the duration of a shock and reduce any injuries that might occur with that shock. They are not just "life saving" devices.

It will stop most of them !
And that, makes it worthwhile !


In some ways it is good that it will not competely stop all shocks
but instead minimise them to the point where fatalities are rare.
If he/she gets a small brief shock after playing with a recepticule,
then he/she learns a lesson, " not pleasent dont do it."
If the gfci 100% stopped it all, then they would just keep playing
with the recepticules and sooner or later a real accident would happen.

It might not be a pleasent thought for a parents to think that there child
has to experience real pain, but it is a fact of life, that's how we all learn lessons in life,
And learning not to play with electricity is vital for children.

They are required in kitchens, bathrooms, basements and garages. Oh, and laundry rooms. Six years ago I tore out the old BX wiring and installed GFCI protection in the garage.

A couple of years later, my three year old daughter was playing in a wading pool. She was soaked, the driveway was wet and I was in the garage doing something. I had a extension cord with a fan plugged in. I looked up and my soaking wet daughter had both hands wrapped around the junction where the fan was plugged into the extension cord, trying to unplug the fan. I jumped up to grab her just as she pulled the two apart. Click! The GFCI tripped.

I was glad I had installed it.

The GFCI is not a catchall for all possible problems....just as the AFCI is not a catchall....but....better than nothing.

I've had mine trip and I never felt anything....

One important thing to remember....it only needs to work one time to be worthwhile....

Electrical safety is an ever evolving technology...what we think it over kill today...50 years from now people may think we were so stupid......case in point....how many people frown at K&T?

that is exactly why they are for outdoor & wet locations. i asume this cord was pluged into an outlet in the garage?

Sometimes so brief you dont realise it has happened.
Vague and fuzzy information, not necessarily true.

Only by learning exactly what circuit breakers, grounding and GFCI actually do can you learn what is safe and what is not.

GFCI protects certain specific shock scenarios, but certainly not all.

GFCI checks the current going into the hot side and back out the neutral side. If they don't match it shuts down. How does this help you? If you are standing in water like a bathtub, and hold a wire in your right hand and stick it in an outlet, GFCI will (theoretically) protect you. Current will be going out the hot, through you, through the water, and into the copper piping. Since the current doesn't return through the neutral side of the outlet, the circuit shuts off.

Next, take a knife in your right hand and another knife in your left hand, and stick them in the 2 slots of an outlet. The current goes into your right hand, through you and your heart, and out your left hand, possibly killing you. The current on both sides is equal, and the circuit does not shut off.

It's true you might not have to tell them again - but unfortunately it might be because they're dead and will not learn a thing. Advice like this is just so bad.
