Mar-Bal, Inc. (Mar-Bal) (defendant) was a plastics manufacturer. As part of its operation, Mar-Bal had employees that used methylene chloride (solvent) to clean Mar-Bal’s equipment at its plant. The solvent caused various health problems when inhaled or absorbed through the skin at high doses, and Mar-Bal was aware that certain safety precautions needed to be taken in order to ensure its employees were safe from exposure. Nevertheless, Mar-Bal had its employees use the solvent without the proper protective equipment and even had employees wash their hands using the solvent. After suffering health problems, a group of employees who were members of the Ailiff family (solvent employees) (plaintiffs) brought an intentional-tort action against Mar-Bal. At trial, a motion for a directed verdict was granted in favor of Mar-Bal. The solvent employees appealed the decision.
