A Insidious Atmosphere is similar to a corrosive atmosphere, but extreme conditions cause the corrosive effects to defeat any protective measures in two to twelve hours.
Description (Specifications)
The term insidious atmosphere is quite sufficient for the layman, but it is far more descriptive if a starship crew person reports that a the ship is about to debark to a world with a hydrogen atmosphere where subtle hydrogen seepage could cause a dangerously explosive air mix inside a crew person's vacc suit, which could be ignited by a spark from the suit's electrical system. [1]
An Insidious atmosphere is so dangerous that it will defeat a vacc suit after just a few hours and kill the sophont inside it. Venus, with its incredible high pressure, high temperature atmosphere comes into this latter category. [2]
Extreme Atmopsheres
Extreme Atmospheres: Some of the more difficult atmosphere types to explain and describe are the 'extremes', types A, B and C which equate to Exotic, Corrosive and Insidious.
- Whereas the Very Thin, Thin, Standard and Dense atmospheres are generally Earth-like in pressures with Earth-like gasses (Nitrogen-Oxygen-Carbon Dioxide mixtures) in a variety of amounts, the 'extremes' are terribly toxic, horribly lethal and utterly alien.
- The three types are really grades of lethality, and an A type and C type atmosphere may actually contain the same poisonous gas, just in different amounts. [3]
Gasses which give an atmosphere an extreme label include carbon dioxide, methane, nitrogen, sulphur, oxygen, hydrogen, ammonia, chlorine and fluorine. These gases are often found in combination with others on the list potentially mixing together with additional dangerous effects into one nasty airborne cocktail! [4]
History & Background (Dossier)
Insidious (C): An insidious atmosphere is like a corrosive one, but it is so corrosive that it attacks equipment as well. The chief danger in an insidious atmosphere is that the toxic gases will destroy the seals and filters on a traveller’s protective gear. An insidious atmosphere worms its way past protection after just a few hours on average, although vigilant maintenance or advanced protective gear can prolong survival times. [5]
