(3) “Animal data:” Human evidence of health effects in exposed populations is generally not available for the majority of chemicals produced or used or used in the workplace. Therefore, the available for the majority of chemicals produced or used in the work place. Therefore, the available results of toxicological testing in animal populations shall be used to predict the health effects that may be experienced by exposed workers. In particular, the definitions of certain acute hazards refer to specific animal testing results ( see Appendix S in OSHA rule ).
(4) “Adequacy and reporting of data.” The results of any studies which are designed and conducted according to established scientific principles, and which report statistically significant conclusions regarding the health effects of a chemical shall be a sufficient basis for a hazard determination and reported on any material safety data sheet. In vitro studies alone generally do not form the basis for a definitive finding of hazard under the HCS since they have a positive or negative resuit rather than a statistically significant finding. The chemical manufacturer, importer, or employer may also report the results of other scientifically valid studies which tend to refute the findings of hazard.
