Atmospheric conditions on board
113.—(1) A spaceflight operator must maintain adequate atmospheric conditions in the inhabited areas of the launch vehicle, or provide equipment to provide such conditions to each human occupant, by monitoring and controlling—
(a)the composition of the atmosphere including oxygen, carbon dioxide and the need for revitalisation of the internal atmosphere,
(b)pressure, temperature and humidity,
(c)contaminants that include particles and any harmful or hazardous concentrations of gases or vapours, and
(d)ventilation and circulation.
(2) In this regulation “revitalisation” means a process by which the internal atmosphere of the inhabited parts of the launch vehicle is sustained at a healthy level, by introducing oxygen to replace the oxygen which has been consumed and by removing carbon dioxide.
