This course is designed to introduce the chemical engineering student to Layer of  Protection Analysis (LOPA), a simplified, semi-qualitative risk analysis method.  The student is introduced to the concepts of risk, initiating events, layers of protection, safeguards, conditional modifiers, enabling events and tolerable risk. These concepts are illustrated through examples including several example LOPAs .  

After taking this course the student should be able to participate in a LOPA  and understand the LOPA methodology.

Please note that ELA980 has replaced ELA903: SAChE® Certificate Program - Risk Assessment.
