The SCP Foundation's containment of SCP-106, 'The Old Man,' is one of those protocols that feels like it was ripped straight from a horror flick—but way more clinical. They keep him in a sealed chamber lined with electrified steel, submerged in a vat of pH-neutral fluid to slow his corrosive decay. Motion sensors and automated turrets are everywhere because this guy phases through walls like they're made of tissue paper. The real nightmare fuel? If he escapes, they send D-Class personnel as bait to lure him back. It's brutal, but the Foundation's priority is keeping the world from becoming his personal playground.
What fascinates me is how they adapted after early breaches. Originally, they tried lead-lined rooms, but 106 just melted through. Now, they use a secondary chamber with a recall protocol—basically, a 'panic button' that floods the area with radiation, which seems to irritate him enough to retreat. The whole setup screams 'desperate measures,' but when you're dealing with an entity that treats concrete like a suggestion, you get creative.
