The metal was weak enough for his to punch through it at 10-15 times normal human strength, so the creature should be able to cut through it if it could cut through such a suit.

I hadn't realised that he'd changed into the sterile suit before starting the adventure, but the claws would still have been able to cut through the reinforced material given their nature. I don't want to say anything more until the party actually discover what they're dealing with.

I'll grab a shotgun, though, and a set of comms gear.  No one would have time to put on a space suit, though, with only twenty seconds left, even if it's as easy as getting dressed.

The standard issue environmental suits are designed to be used in an emergency and make use of nanotechnolgy. All you have to do is place them against your chest and hit the big red button to get them to inflate around you before compressing back down to form an airtight skin.

Deployment is rated under standard conditions as 2.7 seconds, however some anecdotal accounts have reported deployment taking upto 7 seconds in hostile conditions. For female users you also have to writhe about erotically while the suit is deploying, but that's optional for males.
