Prevention through design (PtD), also called safety by design usually in Europe, is the concept of applying methods to minimize occupational hazards early in the design process, with an emphasis on optimizing employee health and safety throughout the life cycle of materials and processes. [1]
ISO 13849-1 has its origins in the mid 1990s when the European Committee for Standardization (CEN) published EN 954-1, Safety of machinery — Safety-related parts of control systems — Part 1: General principles for design [5] in 1996. In 1999, EN 954-1 was transferred to ISO for ongoing development under the Vienna Agreement.
Once a conceptual design is completed, the other safety strategies should be applied along with the inherently safer design concept. However, in this case, the project cost would significantly increase to have the same risk level at the same reliability relative to if ISD (inherently safer design) was adopted during the conceptual design stage.
The analysis is used during the design phase to identify process engineering hazards together with risk mitigation measures. The methodology is described in the American Petroleum Institute Recommended Practice 14C Analysis, Design, Installation, and Testing of Basic Surface Safety Systems for Offshore Production Platforms.
Safety research aims to create safer products, systems, and practices by incorporating scientific, engineering, and behavioral insights. Ultimately, it seeks to enhance public safety, reduce economic losses, and improve overall quality of life by ensuring that both individuals and communities are better protected from harm. [12]
Process safety is an interdisciplinary engineering domain focusing on the study, prevention, and management of large-scale fires, explosions and chemical accidents (such as toxic gas clouds) in process plants or other facilities dealing with hazardous materials, such as refineries and oil and gas (onshore and offshore) production installations.

The hierarchy of controls is a core component of Prevention through Design, the concept of applying methods to minimize occupational hazards early in the design process. Prevention through Design emphasizes addressing hazards at the top of the hierarchy of controls (mainly through elimination and substitution) at the earliest stages of project ...
