Guidelines for Assessing the Toxic Hazard of Spacecraft Chemicals and Test MaterialsThis document describes the criteria and procedural guidelines used by the NASA/JSC Toxicology Office (JSCSTO), to perform toxicological evaluations. The JSCSTO is responsible for conducting toxicological assessments and assigning toxic hazard levels (THLs) for essentially all chemicals and test materials to be used in or transported to the habitable areas of U.S. spacecraft, non‐U.S. spacecraft inhabitaed by U.S. crew members or habitable areas of off‐Earth habitats where U.S. crew members would be present, including chemicals carried by visiting spacecraft(visiting vehicles) to and from the International Space Station (ISS). Biohazard assessments for biological materials used in payload experiments are performed by the NASA Biosafety Review Board. Radioactive materials are assessed by the Space Radiation Analysis Group for radiation hazards; the flammability rating on flammable materials is assessed by the JSC Materials and Processes Branch, ES4. This document will focus on the assessment of chemically‐induced toxicity hazards. The toxicological assessments, together with assessments on radioactive, biological, physical, and flammability hazards, are incorporated into a mission‐specific Hazardous Materials Summary Table (HMST).
