Electrical safety in aftermath of flood

[LMAO]

They were able to find a contractor pretty quick and have already started demolishing the first floor walls so this is resolved. Thank you for all your inputs.

No water above typical outlet level so mostl likely OK for power inside the houses.

Body resistance may reduce with feet/legs submerged in water so that there is greater risk of electrocution.

The most important factor affecting human electrocution is skin-resistance! so, if one is ill, sweating or immersed in water the risk is high!

Once, I knew an electrician... very proud that he could test for voltage by sticking his finger into a lamp socket! I told him, "One day you're going to get kicked in the A..!" If course, that day came when he had a cold!

Another had gotten '440' across the chest. Fortunately, he survived! But, nine months later his wife had a baby! I had a quite a job preventing others from duplicating his mistake!

How does being sick reduce skin resistance?

How does being sick reduce skin resistance?

When your nurse gives you a sponge bath and she doesn't dry you completely.

Any romex exposed to water needs to be replaced. In Washington we adopted the NEMA Guide for Evaluating Water Damaged Electrical Equipment into our electrical rules

This would be very appropriate to have Huston area governments make this document available

To determine a person's total resistance, just add together the resistance of each part of the body - remember that the electricity must pass through the skin twice (on the way in and on the way out,), so the total resistance is:

R_total = R_skin(in) + R_internal + R_skin(out)

If the R_skin(out) is in the feet/legs submerged in water, it will be lower and so R_total will also be lower and hence the risk of electrocution greater.

Not too likely to find two people with exactly same resistance I would think. A majority will fall within a certain range though.

you are *such* an electrician.

Also not too likely to find a person with same body resistance under all circumstances. But it is not that my statement in my last post is false.
