Why would Sevestapol have a lot of panels that need to be cut open in an emergency?

Note: I am not 100% sure where this question belongs. I thought about Space Exploration, but the question can apply to non-space-faring structures.

Alien Isolation frequently uses control panels and sometimes ducts that need to be cut open with a plasma torch. Always painted on these panels is "Cut open in case of emergency" or some such instruction (see below). Now, I know full well that A:I is going for a very specific type of 70's-80's sci-fi and this may very well BE retro sci-fi thinking, but I was curious if this type of practice happens anywhere in the real world?

What would be the benefit of sealing off a control panel that needs to be cut open with a torch, if there is any beyond being an obstacle in a video game?
