Describe how the team attempted to "Decon" the monkey hourse

They started to decon with brushes and bleach, but they couldn't remove the feces, it was like "cement."

"The next day, they went to a hardware store and bought putty knives and steel spatulas, and the decon team went to work chipping the walls and floor. They almost suffocated from the heat inside their suits."

"THE DECON TEAM scrubbed the building with bleach until they took the paint off the concrete floors, and still they kept scrubbing. When they were satisfied that all the building's inside surfaces had been scoured, they move on to the final stage, the gas. The decon team taped the exterior doors, windows, and vents of the building with silver duct tape. They taped sheets of plastic over the exterior openings of the ventilation system. They made the building airtight. At various places inside the monkey house, they set out patches of paper saturated with spores of a harmless bacterium known as Bacillus Subtilis Niger will kill almost anything."

"The team laid an electric cable along the floor throughout the building, strung with outlets, like a cord for Christmas-tree lights. At points along the cable, they plugged in the Sunbeam frying pans. They wired the cable to a master switch. Into each Sunbeam frying pan they dropped a handful of disinfecting crystals."

"1800 hours on December 18, someone threw the master switch, and the Sunbeams began to cook. The crystals boiled away, releasing formaldehyde gas. Since the building's doors, windows, and vents were taped shut, the gas had nowhere to go, and it stayed inside the building for three days."

Finally, after the gassing was complete, the spore samples came back clean.
