Hmph. I guess I'll have to drastically revise my model. I suppose one could simply make it an END check per 5 seconds' exposure.

Wouldn't the lungs burst through the ribcage on the first inhalation?
IMTU: The decompression alarm goes off. Everybody suit up!
Vacc Suit - No Skill: Okay, you got it on ... barely! Now try to figure out what these little do-dads have to do with various bodily functions, or how you're going to get anything done with your helmet on backwards.
Vacc Suit - 0: Let's see ... what have you forgotten ... meh, not important ... but what's that hissing sound?
Vacc Suit - 1: You've been assigned to guide the noob with his helmet on backwards over to the rescue ship. Good luck ...
Vacc Suit - 2: You're getting good at this. Everything seems to be connected and running well.
Vacc Suit - 3: You can do this in your sleep, and probably did! All indications show that your suit is sealed and functioning normally.
Vacc Suit - 4+: You may as well have invented Vacc Suit technology!

Only if you use a real baggy.
If, however, you engage your brain & use a hood designed for emergency breathing in a vacuum, it won't!
Sigh... quit taking Hollywood as reality... THEY ARE F^^%$G WRONG!

By the way, here is a previous 6-page thread here in the CT section titled Vacc Suit Skill: http://www.travellerrpg.com/CotI/Discuss/showthread.php?t=10870

No, the ribs can easily hold 2-3ATM of difference, IF the losses through the breathing passages are negated. Persons on medical air routinely get +0.25atm, so a .2atm 25% O2 should be useful. If you can provide 7psi on the ribs and diaphragm, you should be able to use normal mix at .5atm. Even so, it's going to take about 30PSI to result in damage to the ribs (dislocations) and 45psi before serious risks of rupture... and 1ATM is 14.something PSI. But the lungs have difficulty exhaling when differential exceeds 1Atm. Even half an ATM is tiring.
In fact, the new NASA funded design is essentially a pressure bandage bodysuit with a helmet sealing to the shoulders, and air to the helmet.
A wetsuit a half-size too small is all that really is essential... anything that makes breathing in slightly hard in 1atm will make breathing while the body is in vacuum easier, since it will provide the pressure absent from atmospheric pressure against the outside of the body.
Now I seem to recall something about 1 cubic foot per minute of activity... at 1atm. Tape a bag to your shoulders and you'll get a cubic foot or two... and suffocate, but not suffer vacuum deoxygenation (which causes the O2 to leak out into the vacuum, and speeds oxygen deprivation...), and thus have normal suffocation duration... Probably End x6 sec of unpenalized activity...
And explosive decompression doesn't cause much physical trauma; 90% of the damage is loss of moisture in the eyes and ruptures of the alveolai due to dehydration and capilary bursting... which are due to the alveolai being exposed to vacuum.

So the short answer, Carlparl, is yes, a baggy would buy you enough time to put a suit on. Your body would probably have bruises like going a few rounds with Mike Tyson, but it wouldn't kill you.
Your practical problems would start when you put the suit on.
If you're using an air-hose, how do you disconnect the hose to don the helmet?
If you're just using residual contained air, how do you hole the bag to let air in once your helmet's on?
Either way, a steamed-up baggy inside the helmet will probably interfere with your vision, breathing, or both.
You might be able to rip the bag off and put the helmet on and pressurise it in your few seconds of action time, I suppose, but:
If the vacc suits are of the tailored variety, forget putting your own on. Your body won't burst, but it will be swollen to a size or two bigger. You could don a TL7 type, or a tailored suit belonging to a bigger guy, maybe, if you have a kind GM, and if the bigger guy lets you.
If they are available, rescue balls are a much better idea.
