The filling of the spacecraft tanks with isopropylic alcohol (IPA) during a vibration test increases the fire and explosion hazard. The safety system, based on the nitrogen storage capability of a test house, is described. A safety console is designed for a constant monitoring of the IPA vapors and oxygen rate around the spacecraft. The test volume is reduced by a confinement tent. In the case of a leak: IPA is retained in a half full of water gutter; the test is aborted, the electrical power supplies are cut off; the test volume is inerted using a constant temperature 6 kg/s GN2 supplier.
