A Very Thin Atmosphere is a type of atmosphere which requires a respirator.

  • The atmosphere has a pressure of 0.1 to 0.42 atmospheres, which requires the use of a respirator to ensure sufficient oxygen.

Description (Specifications)[edit]

An atmosphere rated as Very Thin has a mean surface pressure ranging from 0.10 atm to 0.42 atm.

History & Background (Dossier)[edit]

At altitudes above 4,000 meters on Terra, such as most of the Tibetan plateau, the oxygen content in every breath full drops almost to 50%, whilst above 7,000 meters (the peaks of the Himalaya mountains) the lack of available oxygen reaches lethal levels. This extreme altitude on the 'roof of the world' is equivalent to the IISS Scout Code atmosphere of Very Thin. For most explorers, respirators or oxygen masks will be required in this type of environment. [1]
