Exposure to Asbestos During Brake Maintenance: A Comprehensive Overview for Legal and Medical Advocacy
Abstract The study "Exposure to Asbestos During Brake Maintenance of Automotive Vehicles by Different Methods," authored by Timo Kauppinen and Kari Korhonen and published in the American Industrial Hygiene Association Journal in 1987, investigates asbestos exposure among automotive mechanics during brake maintenance. The research measured asbestos concentrations in 24 Finnish workplaces, focusing on various brake repair methods for passenger cars, trucks, and buses. Findings revealed that asbestos exposure levels varied significantly depending on the type of vehicle and repair method, with truck and bus repairs resulting in higher exposure (0.1-0.2 fibers/cm³ as an 8-hour time-weighted average) compared to passenger car repairs (below 0.05 fibers/cm³). The study also highlighted the widespread use of chrysotile asbestos in brake linings, which contributed to occupational exposure. The research underscores the importance of safer cleaning methods, such as water washing, to minimize asbestos exposure.
Legal Relevance This study provides critical evidence for asbestos-related legal claims, particularly for individuals who developed diseases such as mesothelioma, asbestosis, or lung cancer due to occupational exposure. The findings support the following legal arguments:
Evidence of Occupational Exposure: The study quantifies asbestos fiber concentrations during brake maintenance, demonstrating that automotive mechanics were routinely exposed to hazardous levels of asbestos. This data can be used to establish a direct link between the plaintiff’s disease and their occupational history.
Negligence by Employers and Manufacturers: The widespread use of asbestos-containing materials in brake linings, as highlighted in the study, indicates that manufacturers and employers were aware—or should have been aware—of the risks. Failure to implement protective measures, such as proper ventilation or personal protective equipment, can be presented as negligence.
Counterarguments to Defense Claims: Defense teams often argue that asbestos exposure levels were too low to cause harm. This study provides concrete data showing that certain brake maintenance tasks, such as grinding new linings or cleaning with compressed air, resulted in significantly high asbestos concentrations, refuting such claims.
Historical Context: The study also notes that past exposures were likely higher than those measured during the study period, further supporting claims that long-term exposure contributed to the development of asbestos-related diseases.
By linking brake maintenance work to asbestos exposure, this study strengthens the plaintiff’s case and supports claims of liability against manufacturers or employers for failing to protect workers from known health hazards.
Occupation Groups at Risk The study identifies automotive mechanics as a high-risk group for asbestos exposure. Below is a detailed list of occupations most affected, with explanations of why these groups are vulnerable:
Automotive Mechanics: Mechanics working on passenger cars, trucks, and buses are at high risk due to frequent exposure to asbestos-containing brake linings. Tasks such as grinding, cleaning, and replacing brake pads release asbestos fibers into the air, which are then inhaled.
Heavy Vehicle Technicians: Workers repairing trucks and buses face higher exposure levels (0.1-0.2 fibers/cm³) compared to those working on passenger cars. This is due to the larger size and higher asbestos content of brake linings in heavy vehicles.
Garage Supervisors and Workshop Staff: Supervisors and other staff in automotive repair shops may also be exposed to airborne asbestos fibers, especially in poorly ventilated environments.
Industrial Maintenance Workers: Workers involved in maintaining machinery with asbestos-containing components, such as brakes or clutches, are similarly at risk.
Asbestos Quarry Vehicle Mechanics: The study mentions cases of mechanics working in asbestos quarries, where exposure levels are compounded by environmental contamination.
These occupations are particularly vulnerable due to the lack of protective measures historically implemented in workplaces, as well as the high asbestos content in brake linings used during the study period.
Current Medical Understanding The study aligns with current medical knowledge regarding the health risks of asbestos exposure. It is well-established that inhaling asbestos fibers can lead to severe diseases, including:
The study’s emphasis on safer cleaning methods, such as water washing, is consistent with modern best practices for minimizing asbestos exposure. It also highlights the need for continued vigilance and protective measures in workplaces where asbestos exposure remains a risk.
