http://www.cnn.com/2009/US/03/18/chinese.drywall/index.html(CNN) -- Officials are looking into claims that Chinese-made drywall installed in some Florida homes is emitting smelly, corrosive gases and ruining household systems such as air conditioners, the Consumer Product Safety Commission says.
Gas emitted from defective drywall corrodes copper wiring, turning it black, some Florida homeowners say.
The Florida Health Department, which is investigating whether the drywall poses any health risks, said it has received more than 140 homeowner complaints. And class-action lawsuits allege defective drywall has caused problems in at least three states -- Florida, Louisiana and Alabama -- while some attorneys involved claim such drywall may have been used in tens of thousands of U.S. homes.
Homeowners' lawsuits contend the drywall has caused them to suffer health problems such as headaches and sore throats and face huge repair expenses.
The drywall is alleged to have high levels of sulfur and, according to homeowners' complaints, the sulfur-based gases smell of rotten eggs and corrode piping and wiring, causing electronics and appliances to fail.
"It's economically devastating, and it's emotionally devastating," said Florida attorney Ervin A. Gonzalez, who filed one of the lawsuits. It would cost a third of an affected home's value to fix the dwelling, Gonzalez said.
"The interior has to be gutted, the homeowners have to continue paying mortgages, and they have to pay for a
place to live," Gonzalez said.
The CPSC has been investigating claims in Florida for more than a month, according to commission spokesman Joe Martyak. He would not confirm whether CPSC is checking other states or reveal how many cases it is probing.
The Florida complaints generally involve homes built or renovated in 2005 and 2006, when a building boom and post-hurricane reconstruction caused a U.S. drywall shortage that spurred builders to turn to imports, Martyak said.
The allegations come after a number of recent safety problems with other Chinese exports, ranging from toys to pet food.
Dick and Nancy Nelson, who say the Florida retirement home they bought new in 2006 has Chinese-manufactured drywall, contend all their appliances with copper are failing, according to CNN affiliate WFTS-TV.
"The washing machine, the dryer, the microwave, a refrigerator -- these are all brand-new appliances, and they're breaking down," Nancy Nelson of Palmetto told the Tampa station. The Nelsons are among those who have complained to the state health department.
