One of my adventures requires the party to visit a space colony called the ARK. Due to an accident in the reactor silo, the walls of the colony are unstable. As a result any type of heavy damage will cause a hull breach and anything not secured will be sucked out into space.

Here's the table for the size of the breach.

Table: Decompression Times Breach Size
Decompression Time

Fine (1-inch square)
3 rounds per 10-foot cube of air

Diminutive (3-inch square)
3 rounds per 10-foot cube of air

Tiny (6-inch square)
2 rounds per 10-foot cube of air

Small (1-foot square)
2 rounds per 10-foot cube of air

Medium (2 1/2-foot square)
1 round per 10-foot cube of air

Large (5-foot square)
1 round per 10-foot cube of air

Huge (10-foot square)
1 round per 20-foot cube of air

Gargantuan (15-foot square)
1 round per 30-foot cube of air

Colossal (20-foot square)
1 round per 40-foot cube of air

Now the colony has a fail safe system that seals any breach that is detected. These airlock doors plug any holes in the wall. What I want to know is what would be a reasonable number of rounds for the PCs to be in danger before the doors completely seal off the breach?

To clarify, I am talking about the time it takes for the doors to fully close.

So, since you're listing of 3.5 size categories, this is a 3.5 campaign then?

Yes. I am using the 3.5 edition books with the d20 system
