PRINCIPAL INVESTIGATOR (S ): Wayland J. Rippstein, and Howard J. Schneider 



EXPERIMENT TITLE/NUMBER : Toxicological Aspects of Skylab Program 



PROGRAM/MISSION : Skylab 2, 3, 4 



CLASSIFICATION : Human 



DISCIPLINE(S) : Environmental health 



OBJECTIVES : To ensure a safe, habitable spacecraft environment for the 

 crewmen . 



PROTOCOL : A nonmetallic materials screening program was designed to eliminate 

 those materials that would cause problems from their outgassed products. The 

 screening program was based on measuring the amounts of carbon monoxide and 

 total organics outgassed per unit weight of each candidate material. Levels 

 of acceptance were established for both carbon monoxide and total organics 

 based on the spacecraft habitable volume, the trace gas removal rate by the 

 environmental control life support systems, and the cabin leak rate. 



EQUIPMENT : Gas sampling equipment, mass spectrometer, gas chromatograph . 



RESULTS : Results of analyses indicated the presence of approximately 300 

 compounds in the Orbital Workshop atmosphere. 107 of these compounds were 

 identified. 



CONCLUSIONS : The crew was provided with as safe an environment as could be 

 attained using the current state-of-the-art trace gas removal technology. The 

 knowledge gained in solving the trace contaminant problems encountered in the 

 Skylab Program will greatly aid in providing safe, habitable spacecraft 

 environments for the future missions of man in space.
