Kritter keeper+wood shavings+1 inch spider=very bad thing!!!!!!

If the spider is that small, you need to put it in a different container. Even the smallest KK has vent holes large enough for it to squeeze through.

Wood shavings... that says a lot about how much the person you got it from actually knows about proper tarantula care.....IE, not much.
I hope you're going to the store within the next day or two to change that out and make sure to pick up a smaller container.
Granted, you won't need more than a handful or two of substrate.
