Often times asbestos exposure will occur at home, not at work. Clothes laundered from work in an asbestos-containing environment, or building materials like asbestos-containing "popcorn" acoustic ceiling spray, have caused exposures that result in asbestos diseases decades later. Sometimes a location such as a school or office building can cause an exposure from demolition or damage to old steam pipes or insulation. Generally speaking, asbestos was used extensively until the mid to late 1970s. If you have an asbestos disease and don't know how you were exposed, you should immediately investigate making a claim, or risk being time barred by North Carolina's statute of limitations.
