Hydrogen chloride has a robust, irritating odor and is corrosive to any tissue that comes into contact with it, in response to the federal poisonous substances registry. Phosgene smells like freshly minimize hay and may trigger coughing and wheezing if inhaled.

The E.P.A. has been screening houses within the affected space for vinyl chloride and hydrogen chloride. As of Tuesday, it had not detected both gasoline in any of them.
