Abstract
This study evaluated 150 material safety data sheets (MSDSs) for the accuracy and completeness of five areas of information: (1) chemical identification of hazardous ingredients; (2) reported health effects; (3) suggested first aid procedures; (4) recommended personal protective equipment; and (5) exposure level regulations and guidelines. The material from each MSDS was reviewed by both an industrial hygienist and an occupational physician using standard (secondary) references (that were readily available at the time the MSDS was prepared) and a rating system for each area of information. Eighty-nine percent of the MSDSs provided identifiable chemical names. Thirty-seven percent were found to have accurate health effects data (with chronic health information the most inaccurate). The majority of MSDSs (76%) provided adequate first-aid information. Slightly less than half (47%) were judged to have an accurate rating for personal protective equipment information or a correct listing for applicable occupational exposure limits.
