In 2012, the Occupational Safety and Health Administration issued the revised Hazard Communication Standard to bring the US in closer alignment with the Globally Harmonized System of Classification and Labeling of Chemicals, and make the exchange of health and safety information more effective. To evaluate the impact of this change on the reliability and accuracy of safety data sheets, a sample of safety data sheets specific to engineered nanomaterials was obtained by using an internet search engine and subsequently evaluated. These safety data sheets were evaluated using a modified Kimlisch et al. (1997) criteria for ranking the quality of data into categories of reliability and the Eastlake et al. (2012) ranking scheme for scoring four categories. While 86 safety data sheets for nanomaterials were obtained during 2016-2017, 19 of these had no date of completion or revision and could not be evaluated since it was impossible to determine if they were pre or post 2012, when the revised OSHA Hazard Communication Standard was issued. The remaining 67 safety data sheets were ranked by the Kimlisch et al. criteria, and 28.4% (19) were found to be reliable without restrictions (excellent), 35.8% (24) were reliable with restrictions (good), and 35.8% (24) were determined to be unreliable. Evaluating the SDSs using the Eastlake et al. ranking scheme resulted in 3% (2) as satisfactory, 17.9% (12) as being in need of improvement, and 79% (53) in need of significant improvement. It is noteworthy that out of the 79% in need of significant improvement, 25.4% (17) did not have enough data to be evaluated. This evaluation of nanomaterial safety data sheets revealed that the quality of information on many still cannot be relied upon to offer adequate information on the inherent health and safety hazards, including handling and storage of engineered nanomaterials.
