    Abstract. As part of its efforts to promote safe conditions aboard spacecraft, NASA requested the National Research Council (NRC) to develop guidelines for establishing spacecraft maximum allowable concentrations (SMAC's) for contaminants, and to review SMAC's for various spacecraft contaminants to determine whether NASA's recommended exposure limits are .

SPACE- MAXIMUM ALLOWABLE CONCENTRATIONS FOR AIRBORNE CONTAMINANTS The enclosed table lists official spacecraft maximum allowable concentdons (SMACs), which axe guideline values set by the NASMJSC Toxicology Group in cooperation with the National Research Council Committee on Toxicology (NRCCOT).

These values. The first report in the series, Spacecraft Maximum Allowable Concentrations for Selected Airborne Contaminants, Volume 1, published incontains SMAC reports on 11 substances. SMAC reports for additional spacecraft contaminants will be presented in subsequent volumes.

NRC (National Research Council). Sponsored by National Aeronautics and Space Administration, Washington, DC. bcommittee on Spacecraft Maximum Allowable Concentrations (SMAC) reviewed reports prepared by NASA scientists nd contractors recommending SMACs for approximately 35 spacecraft contaminants.

Permissible Exposure Levels for Selected Military Fuel Vapors () Spacecraft Maximum Allowable Concentrations for Selected Airborne Contaminants, Volume 1 (), Volume 2 (), Volume 3 (), Volume 4 (). NASA expects that each crew for the space station will stay aloft for up to days. Limits for continuous exposure to toxic substances for up to 1, days have been recommended for a few chemicals by NRC (, ).

However, the rationale for these limits.

Consequently, exposure limits need to be established for continuous exposure of astronauts too spacecraft contaminants for up to days (for normal space-station operations) and for short-term ( hr) emergency exposures to high levels of contaminants.
