Studies show that products are often judged defective for one or more of the following reasons: 1) manufacturing defects, 2) design defects, 3) inadequate warnings, and 4) inadequate instructions [1, p. 127]. The last two reasons are of particular importance to technical communicators, for we function as the information specialists who link the companies that make the products to the people who use the products. This article examines the relationship between warranties and product liability. It includes a discussion of American National Standards Institute (ANSI) guidelines for safety labels in the workplace and an analysis of warnings and labels as they apply to the pharmaceutical industry. In its closing section, the article discusses some of the key references that technical communicators can consult for additional information on product liability and safety labels.
