Use of Anti-Warnings to Falsely Reassure Downstream Users: An Asbestos Example

Product warnings are theoretically designed to reduce injuries associated with occupational, environmental, or consumer product exposures. Unfortunately, in an effort to protect sales, some companies have produced media and information to falsely reassure their customers about the risks associated with their products. These tactics have been termed "anti-warnings." We reviewed corporate documents uncovered in litigation alongside other historical publications to ascertain the types of anti-warnings used by Union Carbide Corporation (UCC) regarding their asbestos products. Our review finds that UCC went to great lengths to confuse their customers and make their particular asbestos product-which contained short-fiber, chrysotile asbestos-look safe. We discuss three primary communications methods UCC used: industry-produced publications, sales force direct communication with customers, and public speeches. These examples provide further insight into how corporations encourage uncertainty about the risks associated with their products. Understanding anti-warning methods is critical for the implementation of future policies that protect consumer, worker, and environmental health.
