Expedition 43 Commander and NASA astronaut Terry Virts sits is one of the hatchways aboard the International Space Station following the relocation of the Leonardo Permanent Multipurpose Module (PMM.) The PMM was relocated from the Unity node to the Tranquility node as the next step in preparing the International Space Station for the installation of new International Docking Adapters which will enable future U.S. commercial crew vehicles to dock to the station. Crew members typically wear personal protective devices (mask, glasses, gloves) whenever opening a hatch following dynamic operations as a precaution.
