You are tasked by the O5 to close the SCP-008 containment chamber to prevent anyone else from getting infected, because there is lots and lots of zombies roaming around the SCP Foundation the Mobile Task Force and the Security Department had to deal.
You then go up to SCP-008's containment chamber with a broken button engineers are trying to fix. Turns out, that button was the one that opens and closes the release of SCP-008. You then decide to get a hazmat suit, and close the containment chamber without getting infected. While you go get the hazmat suit, you ask yourself:
"Why can't the engineers just get the hazmat suit and seal the lid shut?"
Then you suddenly get it.
"Oh right, because we don't have that many engineers, and the rest has gone to fix the other SCP controls that got broken."
Engineer: "Hey! Can you seal the lid shut since you got that darn hazmat suit on? I'm working to getting this... grunt FIXED!"
"That's what I was gonna do..."
You then enter the containment chamber with the hazmat suit on.
