Given that the city will be fined by the state the people directly involved should be fired immediately. Only in the city can someone be so negligent as ignoring an alarm and overriding it still keep their job. If this happened in a private company, that person would be fired on the spot. It seems that even the supervisors who did not put safety procedures in place be fired also (if they in fact did not train the workers to follow protocol). I suspect that there is more to this story and the city needs to investigate this matter and take appropriate action.
