Exposure to vacuum is a far worse danger than being exposed to seawater. The lack of air not only causes you to lose consciousness but also means a loss of pressure on the body, which causes swelling and other bodily damage. Ferro was able to avoid it because his entire body is comprised of animate iron.

The transuit we provided you -- the clear suit in your kit -- can protect you from vacuum.

[An awkward pause.]

However, given the current pulses that are downing electronics on the ship, there is a moderate risk of equipment failure. In the event you face a hull breach and your transuit is inoperational, try to hold onto something secure. The backup shielding systems are still operational; if you can avoid being sucked out of the ship, the backup shields will go up and the area you're in will re-pressurize.
