From my story at C&EN:

The University of Hawaii last week settled its case with the Hawaii Occupational Safety & Health Division (HIOSH) regarding a laboratory explosion in March. The settlement reduces the number of violations from 15 to nine and the fine from $115,500 to $69,300. ...

The settlement agreement combines similar violations, including two regarding laboratory exits and, separately, four centering on an inadequate chemical hygiene plan. The reduction in overall number of violations, which were assessed the maximum state penalty of $7,700 each, resulted in the reduced fine. The agreement also revised some wording in the violation descriptions.
