“…The fundamental difference between inherent safety and the other two categories is that inherent safety seeks to remove the hazard at the source as opposed to accepting the hazard and looking to prevent its occurrence or mitigate the effects. A degree of inherent safety can be achieved by consideration of the four basic principles shown in Table 1 from Goraya, Amyotte, and Khan (2004). These principles and other inherent safety concepts are further described in Fig.…”

“…All of these substandard conditions and practices could be attributed to the lack of concern that management had towards safety issues in the mine, which was one of the primary root causes of the problem at Westray. These and other incident causation factors are addressed in the Report of the Westray Mine Public Inquiry-Justice K.

“…1 main, Westray coal mine (from Richard, 1997). Richard, Commissioner (Richard, 1997), and the papers by Amyotte and Oehmen (2002) and Goraya et al (2004). The most critical lessons to be learned from the Westray disaster are ones that transcend industrial boundaries; such lessons are related to the preeminence of both the loss management system and the company attitude toward industrial safety.…”

“…Table 1 provides a brief description of these and other pillars of the inherent safety principle. The reader interested in more details is referred to Kletz and Amyotte (2010), Goraya et al, (2004), Khan and Amyotte (2003), and Bollinger and Crowl (1997). A careful examination of the entries in Table 1 shows similarities between the pillars of the inherent safety principle and Haddon's safety strategies.…”

System safety is of particular importance for many industries. Broadly speaking, it refers to the state or objective of striving to sustainably ensure accident prevention through actions on multiple safety levers (technical, organizational, and regulatory). While complementary to risk analysis, it is distinct in one important way: risk analysis is anticipatory rationality examining the possibility of adverse events (or accident scenarios), and the tools of risk analysis support and in some cases quantify various aspects of this analysis effort. The end-objective of risk analysis is to help identify and prioritize risks, inform risk management, and support risk communication. These tools however do not provide design or operational guidelines and principles for eliminating or mitigating risks. Such considerations fall within the purview of system safety.In this work, we propose a set of five safety principles, which are domain-independent, technologically agnostic, and broadly applicable across industries. While there is a proliferation of detailed safety measures (tactics) in specific areas and industries, a synthesis of high-level safety principles or strategies that are independent of any particular instantiation, and from which specific safety measures can be derived or related to, has pedagogical value and fulfills an important role in safety training and education. Such synthesis effort also supports creativity and technical ingenuity in the workforce for deriving specific safety measures, and for implementing these principles and handling specific local or new risks. Our set of safety principles includes: (1) the fail-safe principle; (2) the safety margins principle; (3) the un-graduated response principle (under which we subsume the traditional "inherently safe design" principle); (4) the defense-in-depth principle; and (5) the observability-in-depth principle. We carefully examine each principle and provide examples that illustrate their use and implementation. We relate these principles to the notions of hazard level, accident sequence, and conditional probabilities of further hazard escalation or advancement of an accident sequence. These principles are a useful addition to the intellectual toolkit of engineers, decision-makers, and anyone interested in safety issues, and they provide helpful guidelines during system design and risk management efforts.

“…and the options are not only for inherent strategies but also for covering passive, active and procedural safety measures. There are also inherent safety-based checklists developed for incident based investigation and process safety management [21,22]. Another potential method is by using inherent safety indices.…”
