Legal Implications of Kietzman and Axelson’s 1973 Study in Asbestos-Related Cases
Abstract The study "Polyolefin Composites: Comparison of Mineral Fillers" by J.H. Kietzman and Dr. J.W. Axelson, presented at the 28th Annual Technical Conference of the Reinforced Plastics/Composites Institute in 1973, evaluates the performance of various mineral fillers, including chrysotile asbestos, in polyolefin composites. The researchers simulated commercial mixing processes to assess the impact of these fillers on the properties of polyolefins, particularly at elevated temperatures. The study found that fibrous fillers, especially chrysotile asbestos, provided superior reinforcement compared to other types of fillers. However, the study also noted the need for special additives to address the accelerated oxidation and heat stability issues of chrysotile asbestos. While the study highlights the material's performance benefits, it does not address the significant health risks associated with asbestos exposure, which are now well-documented.
Legal Relevance This study provides critical evidence for asbestos-related legal claims by demonstrating the widespread industrial use of asbestos and the industry's awareness of its unique properties and challenges. Key points of legal relevance include:
Industry Knowledge of Asbestos Risks: The study acknowledges the chemical reactivity and accelerated oxidation of chrysotile asbestos, which required special additives for heat stability. This indicates that manufacturers were aware of asbestos's unique properties and potential hazards, supporting claims of negligence in failing to protect workers and consumers.
Availability of Alternatives: The study compares asbestos with other mineral fillers, suggesting that viable alternatives were available. This is crucial in legal cases, as it demonstrates that industries had the option to use safer materials but often chose asbestos for cost or performance reasons.
Occupational Exposure Evidence: The study highlights the use of asbestos in polyolefin composites, which were widely used in industrial applications. This supports claims of occupational exposure for workers in industries such as manufacturing, construction, and insulation.
Counterarguments to Defense Claims: Defense arguments often claim that asbestos use was unavoidable or that its risks were not well-known. This study counters such claims by showing that the industry was aware of asbestos's properties and had access to alternative materials.
In summary, this study strengthens legal claims by providing evidence of the industry's knowledge of asbestos risks, the availability of alternatives, and the widespread use of asbestos in industrial applications.
Occupation Groups at Risk The findings of this study are particularly relevant to the following occupational groups, who were likely exposed to asbestos-containing materials during their work:
Manufacturing and Production Workers
These workers were directly involved in the production and processing of polyolefin composites and other materials containing asbestos. The study highlights the use of asbestos as a filler in manufacturing, putting these workers at high risk of exposure.
Engineering & Technical Workers
Engineers and technical professionals involved in the design, testing, and evaluation of composite materials, including those containing asbestos, were likely exposed during research and development processes.
Insulation & Fireproofing Workers
Asbestos was commonly used in insulation and fireproofing applications. Workers in this field may have handled polyolefin composites containing asbestos, increasing their risk of exposure.
Construction & Remodeling Workers
These workers often encountered asbestos-containing materials, including polyolefin composites, during construction, renovation, or demolition projects.
Material Handling & Transportation Workers
Workers responsible for handling and transporting raw materials or finished products containing asbestos could have been exposed to asbestos fibers during these processes.
These groups are at high risk due to their direct or indirect contact with asbestos-containing materials, as discussed in the study. The widespread use of asbestos in industrial applications during the 1970s underscores the potential exposure risks faced by these workers.
Current Medical Understanding The study aligns with current medical knowledge regarding the health risks of asbestos exposure. While it focuses on the performance benefits of chrysotile asbestos in polyolefin composites, it inadvertently highlights the material's chemical reactivity and potential to degrade, which are now recognized as significant health hazards. Current medical research has established that asbestos exposure can lead to severe diseases, including:
The study's findings on the chemical instability of chrysotile asbestos reinforce the understanding that asbestos fibers can become airborne and pose significant health risks when inhaled.
