Thousands of U.S. homes tainted by Chinese drywall should be gutted, according to new guidelines released Friday by the Consumer Product Safety Commission.

The guidelines say electrical wiring, outlets, circuit breakers, fire alarm systems, carbon monoxide alarms, fire sprinklers, gas pipes and drywallneed to be removed.

"We want families to tear it all out and rebuild the interior of their homes, and they need to start this to get their lives started all over again," said Inez Tenenbaum, chairwoman of the commission, the federal agency charged with making sure consumer products are safe. From the Associated Press.
