Safe, breathable air is essential for crew health. Human spaceflight has involved toxicological events ranging in severity from trivial to life-threatening. Toxic exposure to chemical contaminants can originate from environmental system leaks, payload leaks, pyrolysis of polymeric materials, off-gassing of polymeric materials, use of utility compounds, propellant entry, microbial products, and human metabolism.
To ensure crew safety, these risks are mitigated by preventive measures aimed at reducing or eliminating toxic exposure events as well as by monitoring and intervention post-release to minimize impacts to crew and reduce impacts to crew health and performance as well as long-term health consequences.
Boeing team members don hazmat suits as they prepare for the landing of Boeing's CST-100 Starliner spacecraft at White Sands Missile Range's Space Harbor, Wednesday, May 25, 2022, in New Mexico. Boeing's Orbital Flight Test-2 (OFT-2) is Starliner's second uncrewed flight test to the International Space Station as part of NASA's Commercial Crew Program. OFT-2 serves as an end-to-end test of the system's capabilities.
