Maybe you can be quick enough to run around and get a object stuck in that door and crouch under? :) After shoving objects on the other side via the hole
I have been putting objects through the gaps on the tops of the closed doors, after all the debris drops down it blocks the path there is nowhere to go sorry.
the first door when you start tells you that the door is „rusty and you need something to break it with“. After that find something that could break it with in lockers maybe. The experience starts then.
