Have you ever experienced
an electric shock? If you have, it probably occurred because some part
of your body contacted
a source of electrical current and your body provided a path for the
electrical current to go to ground. This "leaking" of electrical
current from the circuit to ground is called a ground-fault. If your
body is the path for the ground-fault you could be shocked, burned
or even electrocuted. Take the following examples:
- Two children, ages five and six, were electrocuted
in Texas when a plugged-in hairdryer fell into the tub in which they
were bathing.
- A three-year-old Kansas girl was electrocuted
when she touched a faulty countertop appliance and the water faucet.
- A 52-year-old man was working outside when he
went to switch on a lamp located on the wet ground. When he touched
the case of the lamp he received a shock but was not electrocuted
because the lamp was plugged into a GFCI protected receptacle. Within
one second, the flow of electricity was halted and the man survived.
The lamp was later tested and found to be faulty.
The National Electrical Code has been requiring GFCI
protection for most outdoor receptacles since 1973, in bathrooms since
1975, in the garage since 1978, in the kitchen since 1987, and in crawl
spaces/unfinished basements since 1990. A properly functioning GFCI
device constantly monitors the electricity flowing in a circuit. If
even a tiny amount of current escapes, the GFCI assumes you are at
risk and it shuts off the circuit in a fraction of a second. It does
all that for about ten dollars each. In the field, we often find GFCI
devices that are improperly wired or failed. We recommend that you
plug in a night-light and use the test and reset buttons provided to
confirm operation of each GFCI device monthly. Approximately 200 electrocutions
each year could be prevented by the installation of this ten dollar
device. Tomorrow is too late. |
