Widows DeVries and McAfee claimed their husbands died from cancer due to asbestos exposure while serving on Navy ships that included parts produced by Air & Liquid Systems Corp (ALS). Asbestos installation was required for those parts to function as intended. In some instances, the required asbestos was installed by the Navy after the parts were delivered. Asbestos fibers were then released into the air on the ships. Did ALS and other parts manufacturers have a duty to warn about the risks of asbestos exposure? Explain. See Air & Liquid Systems v. DeVries, 139 S.Ct. 986.
