N95s are made from meltblown polypropylene, produced from plastic pellets manufactured in a small number of chemical plants. Two of these plants were operated by Braskem America in Marcus Hook PA and Neal WV. If there were infections on site, the whole operation would need to shut down, and the factories that turned their pellets into mask fabric would stall.

Someone had the idea: what if we never left? About eighty people, across both plants, volunteered to move in. The plan was four weeks, twelve-hour shifts with air mattresses on the floor each night and seeing their families only through screens. With full isolation no one would be exposed, and they could keep the polypropylene flowing.
The company would compensate them well: full wages for the whole time, even when sleeping, and a paid week off after. They had more volunteers than they had space for.

In those 28 days they produced 40M pounds of polypropylene, enough for maybe 500M N95s.
