Natural Disasters
Natural disasters often cause an unfathomable measure of destruction. Perhaps what makes them so frustrating is they are unpredictable and far from under our control. That said, they produce their own set of hazards that everyone should be aware of; of particular importance to us are the hazards that present themselves after the event. Among these hazards is asbestos. Anytime an event damages property, asbestos should be considered. Below are some specific examples of asbestos exposure hazards within a given natural event.
Earthquake
Earthquakes are among the most destructive natural disasters. The very mechanics of a violent shaking and upheaval will wreak havoc on homes and other structures. It is important to be aware of asbestos exposure hazards in the aftermath of a seismic event. Most buildings built prior to 1980 contain at least some asbestos containing construction components. If these components are damaged in an earthquake, it is possible the asbestos fibers may be released. Asbestos containing materials, when left intact will not emit asbestos fibers as they are locked in compounds. However, when these materials are damaged it is very possible for the microscopic fibers to be released into the air. Asbestos was used in many construction materials but was most often found in concrete, insulation, and drywall compounds. Nearly all of these materials pose some degree of susceptibility to damage during seismic upheaval.
Hurricane
Hurricane Katrina was a sobering reminder of how little control we have over our property and lives when they stand in the way of nature. That said, even after a hurricane it is important people be aware of possible hazards among the rubble. One of the more common hazards found in the rubble of damaged properties is asbestos. Hurricanes, by their force, will damage property to the point where asbestos fibers could easily be released from their construction compounds. Among the more likely damaged constructions of a home or building during hurricanes are the roofing components. Asbestos was used extensively in nearly all aspects of roofing construction because it was fire-retardant and adept at insulation. Shingles, glues, and other roofing compounds could all contain asbestos. These should be avoided in the event they have clearly been damaged.
