The rest of the sentence which you cut off:

>their technology aims to convert this carbon dioxide into carbon monoxide that can be reused in the iron ore reaction.

Presumably, if they're capturing and reusing a gas, it would need to be contained, and thus isolated from the workers.

Plus, I don't think CO is so deadly that leaks would be immediately dangerous. They could be detected and workers evacuated before any ill effects happen.

CO Leaks are immediately dangerous. 1.3% in an atmosphere is unconsciousness after 2–3 breaths. Death in less than three minutes. Don't ever assume chemicals are safe because they don't sound or feel dangerous. More than 100,000 people in the U.S. visit the emergency department each year due to accidental CO poisoning.
