Thanks to someone in the forum who suggested the "count to 10" rule on high temp cooks. I cooked Char-Woody's excellent recipe for skirt steak (Nuclear temps recommended). I cooked about 4 minutes a side and let it dwell a minute or two. (the dwelling was my own idea). Having read the archives, I know to "burp the Egg". I opened the top, opened the bottom, and waited a few seconds--nothing. I lifted the lid an inch for a few seconds, and was about to lift it up completely, when I recalled the "count to 10" rule. Good thing I did. I only lost a few hairs on top of my knuckles, because after 3 or 4 seconds, Whoomp!. Gets one's attention, it does. So thanks to you, and thanks to C-W for a superb recipe. And if you are going to dwell, be REAL careful.
