Thanks to all the suggestions from my post yesterday I have made an improved liquid airlock that allows dupes to pass though without getting wet so they don't get stressed.  The liquid airlock is crude oil, petroleum, and water stacked at 10g each.  By having the dupe jump though the gap it avoids getting the wet debuff.  The vacuum in the middle also prevents temperature from crossing as well NOTE: I didn't come up with the idea for this, credit goes to @Xyer and @Kasuha from my last post As you can see after Nails passed though there was no "soggy feet" or "soaking wet" stat   This water lock can also handle the extreme temperatures of volcanoes as long as you maintain a vacuum in the chamber holding the volcano.  Make sure you have exo suits too
