I don't think that there would be a need to quarantine people for a poison gas attack. It wouldn't be contagious. This sounds like something else entirely.

They said they suspect poison gas. But they are obviously playing it safe and quarantining people in case they are wrong and it is, God forbid, some sort of bio-attack.
