It needs to be stated: if industrial hygienists had had an appropriate role during the Ground Zero clean-up, the $6.1 billion bill, being fought by certain of the malcontents,  would not be necessary.

Who was responsible for this failure to properly protect the workers at Ground Zero? EPA? NYC Health Department? There are a lot of people who should have, and likely did, know better than to let these people work without the proper protective gear, mainly respirators.
