Fiber Type Crucial In Defending Asbestos Claims

By on March 2, 2012

Asbestos defendants are frequently faced with medical causation testimony from the plaintiff that asserts that, because there is no “safe” level of asbestos exposure, any exposure above some ill-defined “background” level is a substantial contributing factor to the plaintiff’s asbestos-related injury. This theory has become the centerpiece of modern asbestos litigation and discourages minimal exposure cases from going to the jury. However, a strong defense can be mounted to a minimal exposure case, particularly if plaintiff alleges exposure to chrysotile asbestos fibers.

For the toxic tort defense lawyer, an understanding of the two major families of asbestos is critical. From a toxicity standpoint, amphibole asbestos fibers are more potentially toxic than fibers of the serpentine family. Amphiboles tend to: (1) be acid resistant; (2) be persistent in the body; (3) be straight fibers; and (4) contain iron. By comparison,chrysotile asbestos, a member of the serpentine family, has a much more lower toxicity profile, particularly in low exposure settings. Chrysotile: (1) breaks down in the body; (2) is acid soluble; (3) has a soft pliable curly shape; and (4) contains dissolvable magnesium. Because the body handles chrysotile fibers differently, chrysotile is much less potent than amphibole asbestos. An examination of the toxicological literature demonstrates that the mesothelioma mortality risk is much greater from amphibole exposure as compared to chrysotile exposure.

At a meeting of the IADC in February 2012, William G. Hughson, M.D., D.Phil., expressed criticism of the expert opinions commonly expressed by plaintiff experts in asbestos cases concerning chrysotile. Dr. Hughson is the Director of the University of California at San Diego Center for Occupational & Environmental Medicine. Dr. Hughson rejects the view that any exposure above background is a substantial contributing factor to disease and that dose has no bearing on causation. At the same meeting, Bob Manlowe, a lawyer with Seattle-based Williams Kastner, delivered a paper titled, “Literature Refuting Single-Fiber Theory and Zero-No-Threshold/Linear-Dose-Model.” For the asbestos practitioner, the two papers provide a valuable road map to cross-examining plaintiff experts and defending mesiothelioma cases involving chrysotile asbestos.

Don’t Blame Chinese Imported Products!

By on March 13, 2009

In his  recent article, "Made in China: Consumer Product Lawsuits Imported to the United States", Seattle defense lawyer and IADC member Gregory Shelton offers American importers several good suggestions for avoiding potential liability from imported products.  These include: (1) requiring the exporter to comply with all applicable U.S. product quality standards and product safety regulations; (2) obtaining legal counsel in the exporter’s home jurisdiction; (3) requiring the exporter to obtain appropriate insurance coverage from an American or international insurer that will protect the importer in the event of a recall or lawsuit; and (4) retaining good legal counsel early.  I would add to Greg’s checklist: (5) having an independent U.S. consultant available to test, if necessary, the components of imported products, particularly if an American consumer reports a complaint to the company or to the CPSC.  Early independent product evaluation can be critical for an importer in planning its next steps, such as whether to perform a recall or halt future shipments until an issue can be addressed.  There are many good consultant firms to chose from. One excellent consultant up-to-speed on the new CPSC requirements is Exponent.

However, we disagree with Mr. Shelton when he argues that Chinese imports are more likely to result in lawsuits or recalls than imports from other countries.  There is simply no empirical evidence to support this assertion.  To the contrary, China has made enormous progress, particularly over the last year, to police its domestic suppliers.  To blame China for the spate of recalls over the last couple of years is to ignore the past lack of adequate funding for the CPSC, the agency that provides regulatory oversight of consumer products.  Moreover, blaming China results in Americans turning a blind eye to problems in our domestic product supply chain.
