Coaches outside dugout

[bossman72]

Let's say a coach is sitting on his bucket or chair and it's placed right outside the dugout opening in the fence in LBT.

1) What is the call (if any) if a thrown ball or pitch is prevented from going into DBT because of the coach and/or his seat?

2) What is the call (if any) if a fielder is prevented from catching a foul pop up because he got tangled up with the coach and/or his seat?


Please note FED and OBR differences since both rulebooks aren't too clear on the subject. I know FED has the clause about loose equipment, but would that apply here?

Thanks!
