“…The objective of inherent safety is to avoid and eliminate risks by reducing hazardous material and operations in the plant instead of controlling them through additional protection systems (Ahmad et al, 2020). For the safety analysis of the dual crude palm and kernel oil production process, the Inherent Safety Index (ISI) methodology is used (Pu et al, 2023).…”

“…As an extension of social aspects, safety evaluation allows the identification of hazards with the potential to affect the sustainability of the process (Moreno-Sader et al, 2020); while sustainability assessment allows a complete analysis relating economic, energy, environmental, and safety aspects. Different methodologies and indices have been developed to evaluate the safety performance of chemical processes including the Dow Fire and Explosion Index (Dow F& EI), the Numerical Descriptive Inherent Safety Technique (NuDIST), Safety Weighted Hazard Index (SWHI) (Yuan et al, 2022), the Inherent Safety Index (ISI) (Pu et al, 2023), among others. Zuorro et al (2020) used the inherent descriptive numerical safety technique to evaluate the safety of chitosan production from shrimp exoskeletons.…”

“…[ 12 ] In practice, inherent safety is regarded as the top hierarchy for risk management and loss prevention (RM&LP) due to its efficacy in ensuring a naturally and fundamentally safer system. [ 13 ] As such, the system designed with inherent safety can operate without extensive passive, active, and procedural protections that need to be constantly inspected, tested, and audited. [ 14 ] With this attractive promise, inherent safety has almost become a common practice in the current proactive RM&LP activities.…”

This study aims to establish a mechanistic model of using inherent safety and health concepts to conduct industrial workplace risk reduction strategies during the project planning stage. Accordingly, a dedicated implementation tool termed inherently safer and healthier design model for industrial workplaces (ISHDM‐IW) is developed. First, the safety and health by design checklist is adapted to derive industrial workplace safety and health risk indicators. Then, the risk indicators are rated and weighted using the methods of risk matrix and precedence chart. Subsequently, the risk indicators are aggregated via fuzzy risk representation with the indicators' risk values and weights. Last, the inherent safety and health principles are used to do risk‐based baseline design optimization. The case study demonstrates the capabilities of the proposed ISHDM‐IW to upgrade the workplace design scheme from risk level II to risk level I, thus generating a more satisfactory workplace design alternative. The proposed ISHDM‐IW offers a novel design mechanism of inherent safety and health for industrial workplaces, which can be expected to ensure employees' safety, health, and well‐being with fundamentally better ergonomics of industrial work environments.

“…Some widely used methods such as hazard and operability studies (HAZOP), failure mode and effects analysis (FMEA), health risk assessment (HRA), quantitative risk assessment (QRA) and others are able to identify 2 of 12 risks, but normally are performed during operational processes-this condition reduces the chances of improvement by changing operative conditions, causing additional costs associated with implementing safety mechanisms (between 15% and 30% of the capital cost) [11]. Therefore, methodologies like the inherent safety analysis (ISI) of processes have become attractive tools for designing safer and more reliable chemical processing routes with the strategy of eliminating risks rather than controlling them [12,13].…”

In this work, a safety assessment was carried out for the suspension polymerization method, known for the lack of studies about its sustainable performance and long history of chemical accidents. Therefore, a safety analysis was conducted using the inherent safety methodology to assess and determine the inherent risks of the poly(vinyl chloride) (PVC) suspension production process using computer-aided process engineering (CAPE). The indicators were calculated using data from safety databases and the specialized literature, considering downstream stages like vinyl chloride monomer (VCM) recovery, PVC purification and PVC drying. The obtained indicators revealed that the process has a negative performance regarding inherent safety, with a total inherent safety index of 30. The chemical inherent safety index had a value of 19, with the main chemical risk of the process being presented by the vinyl chloride monomer (with a value of 11), along with the risk of the exothermic reactions. The process safety index had a value of 15, highlighting the inventory as the primary concern of the process (with a value of 5), followed by the presence of unsafe equipment such as furnaces, burners, and dryers. The safety structure index had a score of 3, categorizing the process as probably risky, with the reaction and purification stages being more susceptible to accidents. Lastly, it is recommended to reduce the size of the process inventory and to substitute out unsafe process units.
