NIAGARA FALLS, N.Y. — Henry Saenz remembers when he first learned what even the tiniest bit of asbestos could do to his body. He was working at a chemical plant where employees used the mineral to make chlorine, and his coworkers warned him about what could happen each time he took a breath: Tiny fibers, invisible to the eye, could enter his nose and mouth and settle into his lungs, his abdomen, the lining of his heart.
They could linger there for decades. Then, one day, he might develop asbestosis, a chronic disease that makes the lungs harden, or mesothelioma, a vicious cancer that ends the lives of most who have it within a few years.
