Survey on indoor air quality in operation room of satellites and fairings

In space development, ambient contaminations might have negative influence on the performance and function of h spacecraft and onboard equipment. In this study, for the purpose of figuring out indoor air quality in operation nd room of satellites and collecting basic data, organic compounds emitted from interior materials of the 2 Spacecraft and Fairing Assembly building (SFA2) and several observations of indoor air quality had been done in SFA2. In consequence, Conductive floor was supposed to be the main source of SVOC. As to Non Volatile Residue (NVR) and particulate matter, each result satisfied qualification of contamination control standard in Japan, and concentration of semivolatile organic compounds (SVOC) was far less than the guideline by the Ministry of Health, Labor and Welfare of Japan, that is based on human health. However, they increased after a year from the completion. Therefore, it was thought that SVOC should be paid long term attention.
