Corrected entry: Take a close look at the masks they are using when they remove the helmet from Kane. The masks they are using to prevent contamination are nothing more than ordinary oxygen masks that one uses at a hospital. This is evident by the hose receptor on the bottom of the masks. In reality these masks would not prevent them from catching any airborne disease that this alien would have. I know they are in a infirmary, but a space ship would/should be better equipped in case it comes in contact with other life forms. (00:36:40)

Correction: While these look similar to current masks, they are part of the highly advanced and miniturized technology of the time - they can do whatever they say that they do.
