Don't be to quick to blame the sound guy... If the Baptistery was lit by
120V underwater fixtures, a failure there could easily be the source of
the voltage and the mic a good source of ground (as it should be).

I'm led to understand that this story or one very similar has been
circulating on the internet for some years - I HOPE it`s an urban legend.
As you say Ralph, it`s more likely that the mike was earthed and it was
the water that was live.

Wasn't posting to lay blame anywhere. Just pointing out how important
it is to ensure that gear is properly wired to ensure that blame CAN'T
be pointed at the jockey behind the desk.
None of the articles that I found online reported the cause of the
electrocution. |

....and agreed that the voltage could very well have been supplied by
improperly functioning apparatus in the area.

Good reason to take a systems approach to both lighting and
sound.
Doesn't the electrical code say the underwater fixtures
should be on a GFCI?
The history of this church is that it was founded in 1996 or
so. It shouldn't be a building with a lot of outdated stuff
"Grandfathered in". |

Ron,
Here are two links to more local sources:
http://www.wacotrib.com/search/content/gen/ap/TX_Pastor_Electrocuted.html
http://www.ubcwaco.org/2004/ubc_holder.html
so I don't believe it's an urban legend.
cheers,
John |

I think it's a reasonable argument to never allow something attached to
a potentially lethal electrical source into a pool of any sort. Even a
relatively small ground loop could be dangerous with enough surface
area of the body being affected because the overall current is greater
from a lot of skin contact. With that kind of massive body contact
area, it doesn't take much available current to affect one's central
nervous system. It would have been prudent for them to be using a
wireless mic.

most baptismals i have seen either use hanging choir mics or wall mounted
boundary effect types.
there had to be half a dozen ways that this could have been prevented. |

Not to mention most I've seen have 240V electric heaters.

GFI 's should be mandatory around water. Our building codes require
that any electrical circuit in the vicinity of water MUST be connected
to a Ground Fault Interrupter Circuit Breaker. As soon as a slight
difference in potential/voltage occurs, the breaker trips off.
Was one installed at this location? |
