Nope. Works in comics, doesn’t happen in the real world.  
Tests with apes have shown that sudden pressure change from “normal” (earth) pressure to near perfect vacuum causes a rapid emptying of multiple bodily fluids (in detail: projectile vomiting, uncontrolled peeing and diarrhea) and death by asphyxiation (if exposed long enough without repressurization), but no exploding parts.  
(I condemn these type of tests, just in case this is questioned.)

Depends on the size of that rift, if it points to a low pressure area that can fill up or open space, and how long it’s open.  
I mean, yes, if it stays open indefinitely and points into space, it will strip the earth of its atmosphere at some point (if not enclosed), but it might take years, or even centuries, so you’d still die of old age first…
