The Geology, Occurrences, and Major Uses of Asbestos: A Legal Perspective

Abstract The 1965 article, The Geology, Occurrences, and Major Uses of Asbestos, authored by N.W. Hendry and published in the Annals of the New York Academy of Sciences, provides a detailed examination of asbestos as a mineral, its industrial applications, and the associated health risks. The study highlights the economic significance of asbestos, with an annual production valued at over $400 million and over 1,000 documented uses. It categorizes asbestos into two main mineral groups, with chrysotile being a prominent type, and discusses its widespread use in industries such as construction, insulation, and welding. While the article acknowledges the safeguards implemented by major industries, it also emphasizes the hazardous exposure faced by workers in smaller industries or those involved in minor uses of asbestos. This study serves as a critical historical document, shedding light on the industrial reliance on asbestos and the health challenges it posed.

Legal Relevance Hendry’s article is a cornerstone in asbestos-related legal claims, as it provides evidence that the dangers of asbestos exposure were known as early as 1965. The study demonstrates that asbestos was widely used across industries, despite the growing awareness of its health risks. This is particularly relevant in legal cases where negligence and failure to warn are central arguments. Key points of legal relevance include:

1. Evidence of Knowledge: The article shows that by 1965, the health risks of asbestos exposure were recognized, particularly in industries with inadequate safeguards. This supports claims that manufacturers and employers were aware of the dangers but failed to take sufficient action to protect workers.

2. Occupational History: The study emphasizes the importance of occupational exposure, particularly in smaller industries where protective measures were often absent. This aligns with modern legal practices that rely on detailed occupational histories to establish causation in asbestos-related disease claims.

3. Counterarguments to Defense Claims: The article counters common defense arguments that asbestos risks were not well understood during the mid-20th century. Hendry’s acknowledgment of the risks associated with asbestos exposure provides a strong basis for arguing that industries had a duty to implement protective measures.

4. Negligence and Failure to Warn: The study highlights the preventable nature of asbestos-related diseases with proper precautions, strengthening claims of negligence against companies that failed to provide adequate warnings or safety measures.

Occupation Groups at Risk The findings in Hendry’s article underscore the significant exposure risks faced by workers in various industries. The following occupations are particularly relevant:

• Construction Workers: Frequent use of asbestos-containing materials such as cement, tiles, and insulation exposed workers to hazardous fibers during installation and demolition.
• Insulation Workers: Asbestos was a primary material in insulation products, putting workers at high risk during application and removal.
• Shipyard Workers: Asbestos was extensively used in shipbuilding for insulation and fireproofing, leading to significant exposure during construction and repair.
• Textile Workers: Involvement in the production of asbestos-containing fabrics exposed workers to airborne fibers.
• Factory Workers: Manufacturing asbestos-containing products, such as brake linings and gaskets, created high-risk environments.
• Carpenters and Roofers: Use of asbestos-reinforced plasterboard and roofing materials often resulted in prolonged exposure to asbestos dust.

These groups were particularly vulnerable due to the lack of protective measures and the widespread use of asbestos in their industries.

Current Medical Understanding From a modern perspective, Hendry’s article provides valuable historical insight into the industrial reliance on asbestos during the mid-20th century. However, it underestimates the long-term health risks associated with asbestos exposure, such as mesothelioma, lung cancer, and asbestosis. Current medical knowledge recognizes asbestos as a significant carcinogen, and its use has been heavily restricted or banned in many countries due to its severe health implications. The study’s acknowledgment of asbestos-related health risks aligns with today’s understanding, but it also highlights the need for stricter regulations and protective measures that were absent at the time.
