JSC 26895, GUIDELINES FOR ASSESSING THE TOXIC HAZARD OF SPACECRAFT CHEMICAL AND TEST MATERIALS (OCT 1997)

JSC 26895, GUIDELINES FOR ASSESSING THE TOXIC HAZARD OF SPACECRAFT CHEMICAL AND TEST MATERIALS (OCT 1997)., his document describes the criteria and procedural guidelines used by the NASA/JSC Toxicology Group (JSC-TG) to perform toxicological evaluations. The JSC-TG is responsible for conducting toxicological assessments and assigning toxic hazard levels for essentially all chemicals and biological materials that are used or transported in the habitable areas of U.S. spacecraft, including chemicals and biologicals carried by the Space Shuttle to and from the Mir and International Space Station (ISS). Hazard assessments for microorganisms used in payload experiments are performed at the request of the JSC-TG by the JSC Microbiology Laboratory. Radioactive materials are assessed by the JSC Radioisotope Working Group for radiation risk; the flammability rating on flammable materials is assessed by the Nonmetallic Materials Branch. This document will focus on the assessment of chemically-induced toxicity hazards. The toxicologic assessments, together with assessments on radioactive, microbiological, and flammability hazards, are incorporated into a mission-specific Hazardous Materials Summary Table (HMST).
