No smoking room please...
Alaska will nicotine test you as part of the drug screening. If I recall correctly, all interview candidates get the drug screen - it is not a "good sign" that you take the whiz quiz.
They will ask you if you have used tobacco in the last 6 months. They will test you. Guess what happens if you turn up positive...
I have no idea where they stand in regards to being fired from a previous job. I would imagine that they would look at each individual case.
I know for a fact that they have hired people who have had an accident or incident. Again, I believe that they look at each person's individual case.
Good luck.
