Oh stop pulling an OP. Unnaturally high levels of CO2 can be dangerous after long term exposure - hours in an industrial environment that already has a bunch of other crap in the air. Carbon Monoxide from your home furnace at high levels knocks you out and kills you in 30 minutes. Still not the same.
