My grandfather died of mesothelioma from asbestos last year. Other than that he was 89 years old and otherwise in fantastic shape for his age, tending a multi-acre garden and working on landscaping. He was not a carpenter, nor was he a contractor. He ran a boiler at a sugar cane processing plant. The only time he was exposed to asbestos was in the day to day operations of that facility. He was not an employee at the time that it was built.
