I definitely smelled something akin to bleach / chloride, in our kitchen, after leaving the windows open all night for fresh air... bad choice. This was after reading the other posts asking about whether the vinyl chloride gas can make it's way over to Boston. The fact that we both smelled the same type of smell means it was real, not imagined. Just unclear if it's from the Braintree fire or made its way over from Ohio. Didnt seem to smell like phosgene or vinyl chloride, at least according to how wikipedia describes the smell of those gases.
