	Air is primarily used to create breathable, pressurized rooms that eliminate the need for EVA suits for humans. It is, however, ill-fitted for use in an EVA suit's oxygen supply, as the nitrogen will not be filtered out of the helmet, which, over time, lowers oxygen concentration in the helmet to unbreathable concentrations. When filling tanks in a nitrox environment, it is advised to use nitrogen filters alongside carbon dioxide filters in the EVA suit to keep the oxygen concentration high in the helmet.

	Breathable air is defined in game as a mixture of 75% [[nitrogen]] to 25% [[oxygen]].		Breathable air is defined in game as a mixture of 75% [[nitrogen]] to 25% [[oxygen]]. (Do NOT use for suit tanks.)

			Clarification: Your suit O2 tank should be 100% [[oxygen]]. If it contains any other gasses, you must include a filter for that type of gas or it will build up in the helmet causing suffocation.

	For a human player, in order to open or remove the space helmet safely, a room atmosphere with at least 16 kPa oxygen (O2) is safe to breathe and does not generate lung-related warnings.		For a human player, in order to open or remove the space helmet safely, a room atmosphere with at least 16 kPa oxygen (O2) is safe to breathe and does not generate lung-related warnings.
	An environment with 16 kPa TO 12 kPA O2 partial pressure will give an OXYGEN LOW warning with yellow lung icon but no damage.

An environment with 12 kPa TO 5 kPA O2 partial pressure will give an OXYGEN CRITICAL warning with red lung icon but no damage

			Partial pressure can be calculated as: partial pressure = (total absolute pressure) × (volume fraction of gas component). For example in an atmosphere of 65kPA with 35% Oxygen the partial pressure can be calculated as '''65 X 0.35 = 22.75''' or 22.75 kPA partial pressure of Oxygen.

If it is too cold or too hot, with open (or without) helmet, it will cause the player to have heavy breathing and/or take lung damage. For a human player the atmosphere should be between 0 and 50°C, if the atmosphere temperature is below 0°C or above 50°C the player will receive a yellow temperature warning, and below -10°C the player will receive a red temperature warning. Below -10°C or above 50°C lung damage will occur.

			Real-world Earth air comprises 78% Nitrogen, 21% Oxygen, 1% Argon, and 0.04% Carbon Dioxide (up from 0.025% pre-industrial level), plus other trace gasses.

			The game allows much more Carbon Dioxide than is typically found in the real-world: anything more that 0.5% CO2 causes headaches, more than 1% CO2 causes cognitive impairment, and more than about 7% causes suffocation (even if there is also sufficient Oxygen).
