Occupational Exposure – Asbestos Exposure and Mechanics: Risks and Prevention

Understanding asbestos and its uses in automotive parts

Let’s start at the very beginning – what is asbestos? Asbestos refers to six naturally occurring minerals composed of thin, durable, and heat-resistant fibrous crystals. 

Asbestos fibers are soft and flexible, resistant to heat, electricity, and corrosion; this explains why it was widely used across different industries, including the automotive industry.

Yet, the critical question we need to ask is, why are we discussing asbestos in an automotive context? Tragically, occupational exposure to asbestos has been widespread, and the automotive industry has been far from immune to its impact. It’s a sad reality that many common automotive parts were historically manufactured with asbestos due to their heat-resistant properties. These parts include:

• Pastillas y forros de freno
• Clutch facings
• Juntas
• Heat seals
• Anillos de válvula
• Hoodliners

Brakes and clutches are subject to extreme heat as part of their regular operation, making asbestos an attractive choice as a component due to its capacity to resist heat-induced wear and tear.

Occupational exposure to asbestos for mechanics

Mechanics and automotive technicians face an under-acknowledged risk – exposure to asbestos, a naturally occurring, hazardous material. Due to the very nature of their profession, they come into frequent contact with asbestos-containing parts.

• In the fast-paced world of a mechanic’s daily tasks, there’s frequent handling or grinding of asbestos-laden parts, primarily in older vehicle models

• When these components – most commonly found in brakes or clutches – are disturbed during repairs or replacements, asbestos fibers can be released into the air

• The threat amplifies when these airborne fibers are inhaled, leading to severe health complications, such as mesothelioma and lung cancer.

Unfortunately, many mechanics may not be aware of the risks of asbestos exposure, even exposure that took place many decades ago. 

En one study, it was found that of brake mechanics tested, most were oblivious to the asbestos exposure risks related to their occupation.

As we’ve already discussed, asbestos exposure’s repercussions are gravely serious and often irreversible. So, the need of the hour is heightened awareness and implementation of safety protocols to safeguard those at risk.

• Safety precautions: Utilizing appropriate safety equipment (like respirators) and following strict work safety guidelines can significantly reduce the exposure risk

• Awareness & training: Regular asbestos awareness and safety training can ensure mechanics understand the risk and take the necessary precautions

• Regulations: Enhanced governmental regulations to minimize the use of asbestos in auto parts could contribute to reducing the exposure risk

Regulations and guidelines for asbestos management in the automotive industry

The collective responsibility of employers and employees in ensuring adherence to these regulations cannot be overstated. These regulations offer workers protection from asbestos exposure as well as precise instructions on how to handle asbestos-containing materials safely.

• Asbestos Identification: As per the Occupational Safety and Health Administration (OSHA), the first step is to correctly identify potential sources of asbestos, such as brake linings, clutches, and gaskets

• Proper handling: Next, the use of appropriate safety equipment is mandated while handling these components. This includes respirators, eye protection, and disposable overalls

• Safe disposal: Finally, safe disposal of asbestos-containing materials is essential. The Environmental Protection Agency (EPA) has strict rules about sealing such materials in leak-tight containers before disposal

These regulations not only guard workers against asbestos exposure, but also give exact orders about the secure handling of asbestos-containing materials. 

For instance, the EPA fined many businesses in 2020 for failing to follow asbestos laws, with some of the fines topping $250,000; that’s why compliance with these regulations isn’t just a matter of avoiding fines, it’s about safeguarding the health and well-being of workers. By fostering a culture of compliance, we can collectively minimize the risk of asbestos exposure and ensure a safer working environment.

Las personas que trabajaron en estas industrias antes de mediados de la década de 1980 tienen un mayor riesgo de desarrollar enfermedades relacionadas con el asbesto:

Construcción	Fábricas	Fundiciones	Refinerías	Astilleros	Minería / Molienda
Demolición	Aislamiento	Trabajadores del acero	Instalación de tuberías	Construcción naval	Mecánicos
Techumbre	Textiles	Trabajadores del hierro	Calderas	Extinción de incendios	Reparación de frenos
Piso	Cemento	Electricistas	Reparación de juntas	Ferrocarril	Climatización

Desafortunadamente también lo hacen sus familias.

Final thoughts on asbestos exposure and mechanics

The specter of asbestos exposure in the automotive industry is a serious concern, with severe health implications for our mechanics and automotive professionals. From lung cancer to mesothelioma and asbestosis, the risks are considerable but, importantly, preventable.

We can significantly lower these risks by being aware of the dangers of asbestos exposure, following the law, and putting protective and preventative measures in place. With shared responsibility and a commitment to safety, we can protect our automotive professionals and foster a healthier, safer industry for all.

In the end, knowledge truly is power. And with that power, we can change the automobile industry so that every mechanic may operate without fear of asbestos exposure in a safe environment.
