U.S. Consumer Organization Identifies Hazardous Plasterboards

In the United States of America, there has been a long-running saga of Hazardous Hydrogen Sulphide (H2S) Emitting Plasterboard/Drywall being installed in new housing.  My U.S. cousin and his beautiful wife were crying their eyes out, here in Ireland last year, having discovered that their new home in Florida had been constructed using this plasterboard … or ‘drywall’, as it is known in the local language over there, i.e. American.

This sorry story graphically illustrates a number of important points …

  1. The Construction Products & Materials Industry is completely and utterly global in nature.  Europe is not immune from this phenomenon !
  2. Within the European Single Market, proper and unqualified emphasis must be placed on the correct CE Marking of Construction Products.  Unfortunately, too many European Manufacturers have not the remotest notion about what CE Marking means or involves.  And … CE Marking Technical Control Systems & Procedures in European Countries are totally inadequate.
  3. Just as many people think nothing about stealing the intellectual property of others … so many people think nothing about Fraudulently Applying the CE Mark to unapproved construction products.
  4. In order to improve the situation concerning Consumer Ignorance about CE Marking … even when a manufacturer has his/her/their CE Marking in order … it is still necessary to clearly and simply demonstrate the Route of Conformity which has been taken in order to obtain the CE Mark.  This is not a requirement of European Union Law … but merely a strong personal opinion based on the experience of being a technical controller for many years.
  5. The problem of hazardous plasterboard in buildings could also happen in Ireland … or in any other European country.  It might already have happened.  Beware !
  6. It is not acceptable that a well-established European Brand Name has engaged in this sort of ‘sharp’ practice outside Europe !!   Across a large trans-national organization … it is essential that Product Quality Control is consistently at a uniformly high level.


In a CPSC (USA) Press Release #10-243, dated 25th May 2010 …

WASHINGTON, D.C. – The United States Consumer Product Safety Commission (CPSC) is releasing today the names of the plasterboard manufacturers whose plasterboard emitted high levels of hydrogen sulphide in testing conducted for the agency by the Lawrence Berkeley National Laboratory (LBNL), in California.  There is a strong association between hydrogen sulphide and metal corrosion.

Of the samples tested, the top ten reactive sulphur-emitting plasterboard samples were all produced in China.  Some of the Chinese plasterboard had emission rates of hydrogen sulphide 100 times greater than non-Chinese plasterboard samples.

“Homeowners who have problem plasterboard in their homes are suffering greatly”, said CPSC Chairman Inez Tenenbaum.  “I appeal to these Chinese plasterboard companies to carefully examine their responsibilities to U.S. families who have been harmed, and do what is fair and just”.

At the US-China Strategic and Economic Dialogue meetings in Beijing on 24th & 25th May 2010, U.S. officials pressed the Chinese government to facilitate a meeting between CPSC and the Chinese plasterboard companies whose products were used in U.S. homes, and which exhibit the emissions identified during the testing procedures.  The Strategic and Economic Dialogue represents the highest-level bilateral forum to discuss a broad range of issues between the two nations.

The following list identifies the top 10 plasterboard samples tested which had the highest emissions of hydrogen sulphide, along with the identity of the manufacturer of the plasterboard and the year of manufacture, from highest to lowest.

  • Knauf Plasterboard (Tianjin) Co. Ltd.: (year of manufacture 2005) China ;
  • Taian Taishan Plasterboard Co. Ltd.: (2006) China ;
  • Shandong Taihe Dongxin Co.: (2005) China ;
  • Knauf Plasterboard (Tianjin) Co. Ltd.: (2006) China ;

  • Temple-Inland Inc.: (2009) U.S. ;   and
  • USG Corporation: (2009) U.S.


Last month, CPSC released the results of plasterboard emissions tests by LBNL.  The studies showed a connection between certain Chinese plasterboard and corrosion in homes.  In addition, the patterns of reactive sulphur compounds emitted from plasterboard samples show a clear distinction between certain Chinese plasterboard samples manufactured in 2005/2006 and other Chinese and non-Chinese plasterboard samples.

To date, CPSC has spent over $5 million to investigate the chemical nature and the chain of commerce of problem plasterboard.  Earlier this year, CPSC and the U.S. Department of Housing & Urban Development (HUD) issued an Identification Protocol to help consumers identify problem plasterboard in their homes.  Last month, CPSC and HUD issued Remediation Guidance to assist impacted homeowners.

Air Travel Crisis in Europe – Know & Claim Your Rights !!

This is very personal … family, friends and I myself … have all been caught, twisted and mangled by the current air travel havoc in Europe.  Catching a plane is stressful enough … the long queues … the security screening … the silly, ineffective regulations about liquids … the unbelievably high prices for everything at an airport (every airport !) … the marathon walks to departure gates … without having to endure the additional stress of not knowing whether the flight is on or off … and even IF you then get to your destination … not knowing whether the return flight will be on or off.

IMPORTANT UPDATE … IATA Press Release #20, dated 18th May 2010 …

[ IATA (International Air Transport Association) represents approximately 230 airlines, comprising 93% of scheduled international air traffic.]

Geneva – The International Air Transport Association (IATA) called on European governments and air navigation service providers to urgently develop more precise procedures to identify ash contaminated air space and allow more flights.  The call came in the wake of 1,000 flight cancellations on Monday (17 May) as a result of the continued volcanic eruptions in Iceland.

“This problem is not going away any time soon.  The current European-wide system to decide on airspace closures is not working.  We welcome the operational refinements made by the Volcanic Ash Advisory Centres (VAAC) in their theoretical model, but we are still basically relying on one-dimensional information to make decisions on a four-dimensional problem.  The result is the unnecessary closure of airspace.  Safety is always our number one priority.  But we must make decisions based on facts, not on uncorroborated theoretical models”, said Giovanni Bisignani, IATA’s Director General and CEO.

Bisignani noted some successful exceptions which provide examples to follow.  “France has been able to safely keep its airspace open by enhancing the VAAC Data with operational expertise to more precisely determine safe fly zones.  Today, the UK Civil Aviation, working with the UK NATS (the air navigation service provider), announced another step forward by working with airlines and manufacturers to more accurately define tolerance levels while taking into account special operational procedures.  Both are examples for other European governments to follow”, said Bisignani.

Bisignani called for (1) more robust data collection and analysis; (2) a change in the European decision-making process; and (3) urgency in addressing the issues.

Data Collection & Analysis:  “Numbers show that the current system is flawed.  Over 200,000 flights have operated in European airspace identified by the VAAC as having the potential presence of ash.  Not one aircraft has reported significant ash presence and this is verified by post-flight aircraft and engine inspections.  We must back the theory with facts gathered by aircraft to test ash concentration.  France and the UK are showing that this is possible.  If European civil aviation does not have the resources, it should look to borrow the test aircraft from other countries or military sources”, said Bisignani.

Changing the European Decision-Making Process:  “We have lost confidence in the ability of Europe’s governments to make effective and consistent decisions.  Using the same data, different countries have come to different conclusions on opening or closing airspace”, said Bisignani.

“Ultimately the industry needs a decision-making process for ash clouds similar to the one used for all other operational disruptions.  Every day, airlines make decisions whether to fly or not to fly in various weather conditions.  Airlines collate the information available and make informed decisions placing safety first and with full access to all the latest weather reporting.  Why should volcanic ash be any different ?”, said Bisignani.

In the US, which has a lot of experience with volcanic activity, the government identifies a no-fly zone where ash concentration is the highest.  For all other areas, it is the responsibility of the airline to decide to fly or not based on the various data sources available.  “The US has well-established, safe and effective procedures for tracking the hazards of volcanic ash.  In recent years, the industry had no recorded safety incidents from volcanic activity in US airspace.  Europe has a lot to learn”, said Bisignani.

Urgency:  “Volcanic ash is a new challenge for European aviation.  We can understand that systems need to be developed to cope.  But, what is absolutely inexcusable is the failure of Europe’s governments to act urgently and collectively to provide real leadership in a crisis.  We have vast amounts of data from over 200,000 safe flights ready for analysis to support an urgent review of the current processes.  The UK is finally moving in the right direction.  But what about the other affected European governments ?  The next transport ministers meeting is scheduled for 24th June 2010.  What kind of leadership waits more than a month to make crisis decisions ?  European businesses are dependant on air travel and passengers certainly cannot wait that long for initiatives like the UK’s to be implemented continent-wide”, said Bisignani.

To enhance the industry’s long-term ability to address volcanic ash issues, Bisignani is travelling to Montreal for urgent meetings with the International Civil Aviation Organization (ICAO).  “IATA and ICAO have been working intensely on this issue since the crisis first struck in April, 2010.  IATA is strongly supporting the ICAO Task Force which is reviewing ash tolerance thresholds with states, operators, manufacturers and the scientific community.  The responsibility of manufacturers is critical in providing performance information to back decisions”, said Bisignani.

Tomorrow, Bisignani will meet Roberto Kobeh-Gonzales, President of the ICAO Council and Raymond Benjamin, ICAO Secretary-General.  “It is important that we act urgently and globally to better deal with this crisis and to lay a solid foundation for better decision making in future eruptions.  Even as Europe stumbles with its fragmented approach, IATA is working with the global community through ICAO and by tapping into the experience of leading regulators like the U.S. Federal Aviation Administration (FAA) to facilitate harmonized solutions”, said Bisignani.


Earlier Information Which Is Now Very Interesting !   … EEA Press Release, dated 23rd April 2010 …

Volcanic Ash is Having Little Impact on Europe’s Air Quality

Copenhagen – The European Environment Agency (EEA) is closely following the impacts of recent volcanic eruptions in Iceland, in particular assessing changes in ground-level air pollution.  According to preliminary monitoring data, ground-level air quality across Europe has not deteriorated significantly as a result of the volcanic activity.

Volcanic eruptions have the potential to inject substantial amounts of sulphur dioxide (SO2) and ash into the atmosphere.  Volcanic aerosol, a suspension of fine solid particles or liquid droplets in the air, is created during eruptions and can be transported thousands of kilometres.  Particles in the volcanic aerosol may carry pollutants with the potential to harm human health and ecosystems.

So far, monitoring stations in Europe have only detected a few episodes of ambient air concentrations of particulate matter and sulphur dioxide of volcanic origin, in particular at elevated mountainous locations, for example at Zugspitze in Germany (2,659 m).  The threat to public health in the European Union is therefore considered minimal at present.

On Iceland, however, the situation is different: concentrations of particulate matter are markedly higher than usual in some areas.  That potentially represents a significant threat to humans and farm animals, according to the Icelandic Directorate of Health, which closely monitors pollution levels.

In Europe, rain and snowfall are expected to remove volcanic debris from the atmosphere.  Detecting this process requires the chemical content of precipitation to be analysed, which takes time.  Should these data indicate high pollutant levels, the current assessment of risk for human health and ecosystems may need to be reassessed.

The EEA maintains a public air quality information system, Air Watch, within its Eye on Earth Portal.  It displays near real-time measurements of concentrations of three air pollutants (ground-level ozone O3, particulate matter and nitrogen dioxide NO2) from approximately 1,000 monitoring stations in 32 countries, as well as updates from citizens.

Because ambient air concentrations and fallout can vary across short ranges within Europe, the EEA also advises the public to refer to national or local air quality authorities, which may have additional or new information on local conditions.  Detailed information on national and local data providers is also available via Eye on Earth.
