Throat and Gastrointestinal Cancers: Asbestos fibers released from damaged or deteriorating cement materials can be ingested or inhaled, leading to cancers of the throat, stomach, and intestines. Individuals working in asbestos cement manufacturing, construction, and renovation are at increased risk of these conditions.
How Asbestos Exposure Occurred from Cement Products
Asbestos cement products, while widely used for their durability and fire-resistant properties, posed significant health risks due to the release of asbestos fibers during various stages of their lifecycle. One of the primary exposure threats occurred during construction and installation. Cutting, drilling, or shaping asbestos cement sheets, pipes, and panels released microscopic asbestos fibers into the air. Workers involved in these activities, such as construction laborers, roofers, and plumbers, were at high risk of inhaling these fibers, which could remain suspended in the air for extended periods.
Another major source of exposure was during demolition and renovation of buildings containing asbestos cement products. When old asbestos cement siding, roofing, or insulation boards were destroyed or removed, the disturbance of these materials created airborne dust laden with asbestos fibers. This posed a significant risk not only to workers directly involved in the demolition but also to nearby residents and bystanders, especially in urban areas where such activities were common.
Wear and deterioration over time also contributed to asbestos exposure. Asbestos cement products, such as roofing sheets, pipes, and wall panels, naturally degraded due to weathering, mechanical stress, or chemical exposure. This breakdown released asbestos fibers into the surrounding environment, particularly in older buildings, factories, and municipal water systems. For instance, asbestos cement pipes used in water distribution systems could release fibers into the water supply as they aged and deteriorated, posing a potential ingestion risk.
Transportation and handling of asbestos cement materials further exposed workers to hazardous fibers. In factories, warehouses, and construction sites, workers handling these materials often encountered fiber dust during packaging, transport, and cutting. Damaged or poorly sealed packaging could release fibers into the air, while manual handling of asbestos cement products without proper protective equipment increased the likelihood of exposure.
In addition to these direct exposure threats, non-occupational exposure was also a concern. Family members of workers who handled asbestos cement products could be exposed to fibers brought home on clothing, tools, or equipment. Furthermore, the improper disposal of asbestos cement waste in uncontrolled dumps or open areas could lead to environmental contamination, affecting nearby communities.
