What should every graduating chemical engineer know about process safety and how can we make sure that they do?This paper will present an overview of critical topics that all graduating chemical engineeringstudents should know regarding the “hazards associated with these processes” as specified by theABET program specific criteria for Chemical Engineering.i The paper draws onrecommendations from recognized leaders in the area of chemical process safety, typical topicscovered in textbooks on the subject, and a review of program requirements at several ChemicalEngineering programs. The paper will present various strategies to satisfy the ABET programspecific criteria.A review of safety modules produced by SACHE for use in Chemical Engineering programsyields the following popular topics:ii 1) process safety management, 2) inherently saferprocesses/design, 3) runaway reactions, 4) chemical reactivity hazards and material properties, 5)pressure relief and venting, 6) explosion hazards, 7) chemical transportation and handling, and 8)process hazard analysis and risk analysis. These same or similar topics are discussed to varyingdegrees in popular textbooks used in Chemical Engineering senior design courses, texts such asthose by Turton et al.iii, and Towler and Sinnottiv. There are also a few specialized texts that areused in courses dedicated to chemical process safety and other related areas such as those of Rayand Reiskev, Crowel and Louvarvi, and CCPSvii.The chemical engineering curriculum is often packed with required courses in the engineeringsciences, unit operations, laboratory experiences and capstone design. While one commonapproach to fulfilling the ABET requirements is to offer a dedicated course in process safety,many programs find it difficult to fit a three credit course into their curriculum. A furtherdisadvantage of a dedicated course for all students is the compartmentalization that comes with aseparate courseviii. Ideally the concepts of process safety should be covered in context within avariety of courses. Integration of SACHE modules is one possible way to achieve this context.For example, in a Chemical Kinetics and Reactor Design course a SACHE module on runawayreactions should be discussed. When coupled with a unit operations laboratory safety programsuch as described by Vaughenix this can be an effective approach. A separate one or two creditprocess safety course can also be used to cover critical concepts that may not integrate well intoother courses. Some specific examples including the approach at _______ will be described.
