How to escape HMP-Irongate

Does anyone know how to escape HMP-Irongate. I know you need a raft. Other than that though I have no idea what to do!

I have a lot of forks, knives, and spoons. I have a raft, a baton, and a guard outfit. I play on console. (I’m mentioning this because the cops won’t have stun guns.)

Can anyone give me any tips?
