“…Controls are then added. On the left‐hand side are blue threat controls or preventative safeguards [ 13 ] (eg, engineering or administrative controls) put in place to avoid loss of containment. Yellow controls on the right‐hand side are mitigation controls or mitigative safeguards.…”

“…Many industries are combining these three fields in their operational discipline initiatives and are identifying and managing more risks in their work environments. [12,13] This paper presents a case study for the combination of process safety management (PSM), OH&S, and behavioural safety approaches using bow tie diagrams in the oil sands industry. In addition to retrospectively implementing controls and learnings, these diagrams can also be used as a dynamic visual tool to promote dialogue, ownership, and innovation of the controls used to mitigate OH&S, behavioural, and process safety hazards.…”

Combining safety approaches to bring hazards into focus: An oil sands tailings case study

At least 50 hazardous occurrences associated with tailings facilities occurred in the Canadian mining industry between 2000-2014. Further investigation revealed a dearth of information on worker safety around tailings storage and transport facilities. Workers at oil sands tailings operations are exposed to hazardous scenarios, including loss of containment and line of fire. These are the similar scenarios that manifest in traditional process industries, with the notable differences between traditional process industries and tailings operations being the frequency of incidents, pressures, volumes, and temperatures. The presence of hazardous scenarios and lack of incident reviews illustrate the need for increased attention to be paid to worker safety at oil sand tailings operations as well as enhancements to current hazard identification tools. Process safety management tools such as bow tie diagrams can be applied to tailings operations to visually identify unwanted events (process and occupational health and safety related), potential threats, consequences, and controls used to prevent incidents from occurring. They also serve as a tool for continuous improvement and show any over-reliance on one type of control, such as administrative controls or personal protective equipment. This research combines safety approaches using the bow tie analysis of seven hazardous operational activities in the oil sands tailings operations as a case study. The impact of behavioural safety on the controls is also analyzed. This research facilitated the sharing of tailings safety best practices among oil sands operators and regional contractors.

“…The impact of OD on process safety risks can be expressed by qualitatively modifying the risk equation (Equation ) by adding an OD expression to the denominator. Since there are many individual and organizational factors that affect OD, including their impact on the frequency (eg, the initiating causes and the probability of failure for process equipment), the impact of OD on risk, with the risk being a function of the OD‐related “measure,” is shown in Equation () 7,10 :

Risk ((), R) = \frac{Frequency \times Consequence}{f ((), Operational Discipline)} = \frac{F \times C}{f ((), OD)}

This paper presents the results from more than 50 incidents attributed in part to the process safety risks associated with abnormal, transient operations during start-ups and shutdowns. A transient operation is defined in this paper as the time when the process is in transition between one operating state and another. In particular, the transient operations-related focus is on the time when equipment is taken from its safe, idle state to its safe operating conditions (a start-up) and vice versa, when the equipment is then taken back to its safe, idle state (a shutdown). There are 10 different start-up and shutdown operating modes during normal operations, abnormal operations, and emergency operations. The incidents in this review were attributed to weaknesses in administrative controls that did not work as planned and engineering controls that did not perform as expected. Due to these weaknesses, unexpected events occurred, resulting in quick decisions made without adequately understanding the hazards, evaluating the risks, or managing the changes. In many cases, had the asset integrity and reliability program been in place or effective operational readiness review performed before attempting the process restarts, the risks associated with the transient operating mode could have been reduced.

“…The intent and concept for each of these eight systems is shown in Table . Please refer to the literature for more details on these concepts, including how they have been successfully implemented in industry . The final risk management controls, both engineering and administrative, are implemented and are used to achieve and maintain safe and reliable operations during the process and equipment life time.…”

One of many efforts to help instructors teach process safety‐related concepts to undergraduate chemical engineers includes using AIChE's web‐based Concept Warehouse, a real‐time, interactive teaching tool which can be used during lectures when teaching chemical engineering subjects. This article describes a student outreach effort by the AIChE Safety and Health Division to help populate the Concept Warehouse with vetted process safety‐related problems. The purpose of this article is to describe how we are bridging the gap between the practitioner volunteering their expertise and faculty members interested in incorporating current process safety‐related concepts into their classes. The goal for this effort is to provide a comprehensive instructional tool that can be used to help teach process safety‐related engineering design concepts, as well as to help teach the essential administrative process safety and risk management system concepts, using problems that describe both the engineering and administrative controls required for safe and reliable operations. The Concept Warehouse is an information database and instructional tool accessible to anyone teaching core chemical engineering topics such as thermodynamics, kinetics, or process safety anywhere in the world. This article defines and provides the framework of this effort to populate the Concept Warehouse with process safety‐related problems. As process safety risk reduction efforts continue to evolve, this article provides updates to traditional definitions that can be used to help orient those unfamiliar with these systems‐related process safety risk management strategies. The article concludes with a few example problems which could be used when teaching process safety‐related concepts. © 2018 American Institute of Chemical Engineers Process Saf Prog 38: e12010, 2019
