General Contractors and Asbestos
Asbestos was used so extensively, that very few professions are completely without risk of exposure. Unfortunately, exposures occurred while people were simply doing their jobs and providing for their families. Among the more at risk professions are general contractors.
To understand how asbestos affects certain professions, it is important to realize the scope of the problem. Nearly 80% of structures built prior to 1980 contain some amount of asbestos containing materials (classified as products which contained at least 1% asbestos). Its fibers were so durable and so adept and insulation and heat-resistance, its uses were almost limitless. It could be added to innumerable construction compounds and enhance the fire-retardant qualities of that compound.
Important too, is the stability of the asbestos fibers. Contrary to popular belief, not all asbestos-containing materials are inherently dangerous. Only when they are classified as "friable"(able to destroyed or pulverized by human hand pressure) are they a danger. It is under these conditions that the fibers are able to become airborne, thereby becoming a danger for inhalation. Disturber asbestos fibers are microscopic and can easily then be inhaled.
Contractors find themselves at risk because it is more likely they will encounter older asbestos containing materials. These materials were banned by the Consumer Product Safety Commission in the late 1970's but are still present in many homes and other structures. When these materials are disturbed by contractors, they can release asbestos fibers into the air. For instance, when in the process of pulling up an existing tile floor, older damaged tiles can easily release asbestos fibers into the air. The same can be said for most asbestos containing materials, which can include not only floor tiles, but ceiling tiles, drywall, and home siding. Asbestos could also be added to concrete or adhesive compounds to make them more durable. These materials will typically become damaged when in the process of renovation or removal, creating a clear asbestos hazard in the vicinity.
Over time, asbestos fibers will create a harmful inflammation in the lining of the lung and other internal organs. Inflammation will lead to a dangerous scar tissue, which ultimately, lays the groundwork for the deadly cancer mesothelioma. Those who believe they may have been exposed should speak to a physician well-versed in respiratory conditions about the severity and duration of their exposure. Knowing what to look for and identifying abnormalities early, can greatly improve one’s prognosis in asbestos-related disease.
