Hazardous decomposition Products: Formation of combustible and noxious fumes during thermal decomposition.
危害分解物:热分解时会产生可燃有毒气体。
One letter from local farmers described how a nearby factory making 8-hydroxyquinoline, used as a deodorant and antiseptic, emitted noxious fumes that 「make our days and nights impassable.」
The job can either be to set up a replacement air system - for instance because of a command in connection with exhaust of noxious fumes - or to ensure a minimum temperature in the room.
