Introduction

? Recent Process Accidents and losses ? On January 23, 2010, release of highly toxic phosgene, exposing an

operator leading to death at the DuPont facility in Belle, West. ? On April 20, 2010, a sudden explosion and fire occurred on the

BP/Transocean Deepwater Horizon oil rig. The accident resulted in the deaths of 11 workers and caused a massive oil spill into the Gulf of Mexico. ? On July 22, 2010, an explosion and fire killed two workers at the Horsehead Holding Company zinc recycling facility located in Monaca, PA.
