Lessons Learned – Recognizing and Controlling Thermal Hazards During Test Planning and Test Conduct
Year: 1997
Abstract: Description of Driving Event:
During a thermal vacuum test with a subject in a space suit, the test subject received frost bite on his finger tips, while handling EVA (Extravehicular Activity) tools at -120 degrees F. Under specific conditions the subject in the space suit gloves can be subjected to low temperatures. The Extravehicular tools required difficult functional operation, resulting in extensive handling /contact time. The EVA tools had high thermal conductivity. The Space suit gloves have minimum insulation in the finger tip areas for increased touch and grasp capabilities.
The ensuing investigation revealed that the test team had a low awareness that this hazard existed and that it needed to be controlled.
