What is an FB unit ? Is that the scrubber system to reduce CO2 or whatever gasses from coal fired electric generation ?
At the end of this article which dwells on the consumers woes and ills dwelling on the stuff comming from China.
But not on the sources which would have been helfull,
The article concluds after umpteen paragraphs with finnally mentioning Knauf Plasterboard (a German plasterboard manufacturer) of Tiayin China as the source of the questionable gypsum. But were they the co-owners of the plant making the stuff or a was this a subcontracted deal with the plant which manufactured the stuff under their label. In either case Knauf is responsible for the products quality but it got off lightly in this report...must have been a big Obama contributer (sarc)
Indeed. The Safety Data sheet for a U.S. made board where flyash is used, says the stuff is stable under normal conditions. However, if met with a source of ignition, HEAT or HUMIDITY, hazardous effects are produced. I wonder why no one questioned what would happen if this stuff was used in hot and humid climates, or even, in rooms where hot steam is created like bathrooms, kitchens and laundry rooms. Hydrogen sulfide gas was decteted in many of the homes on my street with it and the families, living for years exposed to chronic low levels have been suffering chronic health problems related to higher exposure levels. The immune system will loose tolerance to low levels and then worse symtpoms can manifest at low levels. It’s nasty stuff. Worse, it is going to take more then gutting the place down to block and studs. My house has been gutted to that level for 7 weeks now, airing out, and reeks really bad. You can choke on the gases coming out of open windows. Everything, including all of our porous furnishings, have been cross contaminated. We had to get rid of the furniture after we moved out. It was contaminated to the core and still able to cause the exposure symptoms. These homes all need to be torn down and rebuilt. BTW, it wasn’t just used in new construction homes. A local fast food chain here, used it when they remodeled 9 of there stores about 8 months ago. This problem has devasted hard working families who were playing by the rules, and trusted in our regulations, and consumer product saftey checks. Realtors in Florida are forcing people to disclose the problem, repaired or not. These homes are worthless. Banks smartly, won’t give loans on them. The check is, blackening to black copper wiring and repeated AC evaporater coil failures. After about two years time, the backs of bathroom mirrors begin corroding along with chrome in the bathrooms showing signs of blackening and pitting. One woman in NC who had chronic pnueomonia, living in a CDW house, went in for surgery to remove chronically infected tonsils. The Doctor said he never saw anything like them. Her tonsils had black holes in them too. Gross.
Not paranoia. All clothing (not just Chinese made) has stuff sprayed on them to keep them from wrinkling in shipment and on display. Some people are more sensitive than others. I too have to wash new clothing before I can wear it, or I get a rash.
Ma'am, we're from the government, we need to do a DNA analysis on your dry wall.
Evaporator coils drip constantly from surface condensation as the cycle extracts moirure from objects in the conditioned space; sulphur fumes in the presence of this ‘sweating’ converts to sulphuric acid, I guess.
True. However, this takes place at 150 to 250 ppm, or 150,000 to 250,000 ppb, not the <500 ppb that has been detected to date in affected homes.
Dosage does matter.
The two types of materials exit the power plant as two separate waste streams. Somebody could have mixed fly ash back into the synthetic gypsum at some point, but analysis of Chinese drywall has to date found no fly ash, which is quite easy to detect.
I believe our problem chiefly is the odor caused in enclosed areas like linen and clothes closets.
Your statement is based on rather short-term tests, I think. I suspect that lower levels of exposure could dull the sense of smell over time. People can lose perception of all kinds of low-level sensory inputs (e.g. their own body odor) with chronic exposure. Incidentally, really high levels of hydrogen sulfide apparently kill the olfactory sense for H2S permanently.
My response was based on the assumption that you were saying H2S has a specific effect at low levels of dulling the sense of smell. This is inaccurate. It has such an effect, one that occurs quite rapidly, but it is at relatively high levels not far below those immediately dangerous to life and health.
The issue you describe is called olfactory fatigue and is common to all odors, not specific to H2S. Anyone around a given odor for long periods of time will eventually decrease in his ability to detect it.
I’ve worked with clients who were positive their 14 cats didn’t create an odor problem in the home. Meanwhile I’m standing there with tears running down my cheeks from the ammonia levels.
No, The body loosing tolerance to low levels, then becoming able to experience the symptoms of higher level exposure at low levels, is based on OSHA/NIOSH longer term tests. Granted, all OSHA/NIOSH tests are generally done on healthy adult men, in the work place. OSHA/NIOSH has no research for CHRONIC (24/7 year after year) exposure to hydrogen sulfide, for infants, children, the elderly, sensitives and pets. In short, these families are the lab rats for such research. This chemical cocktail of sulfur compound gases has no business being found in peoples homes, which is why there have been no case specific studies to reference.
This is not new and didn’t start in China. Underwear made in NC IIRC was just as toxic back in the ‘70s. All you have to do is wash it before you wear it. Common sense is not very common thanks to the quality of our teachers.
Pretty hard to label a pine nut, I would think. Lug nuts would be a little easier.
