Feedback on a SCP - Heavy Containment Zone Hallway Design

For those of you who don’t know, the Heavy Containment Zone (HCZ) is a sector in a SCP Facility which houses more dangerous Euclid/Keter SCPs. (e.g. SCP-096, 009, 106)

What do you think of it? All feedback is welcome! If you think it needs anything just tell me!

Thank you!
