Hazard and Operability Analysis (HAZOP) is used to identify and evaluate safety hazards and operability problems that could compromise a plant's ability to operate safely and/or to achieve design productivity. HEA associates have trained others in the methods for conducting HAZOP reviews, have led teams conducting HAZOP reviews and have participated as members of HAZOP review teams. Examples of projects include:
