The Chemical Screening Tool for Exposures and Environmental Releases (ChemSTEER) is a computer-based software program developed by the EPA's Office of Pollution Prevention and Toxics (OPPT) that can be used to conduct a screening-level workplace exposure and release assessment.
ChemSTEER generates screening-level estimates for environmental releases of and worker exposures to a chemical manufactured and used in industrial and commercial operations (i.e. workplaces). The tool also contains data and estimation methods to assess chemical use in common industrial/commercial sectors (e.g., automotive refinishing) and chemical functional uses (e.g., tackifier in adhesive). ChemSTEER does not contain methods for estimating exposures to chemicals to the general public, to consumers, or to other species in the environment.You may need a PDF reader to view some of the files on this page.
