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]
This is a calculated value, and is sometimes referred to, for the sake of clarity, as a realized factor of safety. A constant required value, imposed by law, standard, specification, contract or custom, to which a structure must conform or exceed. This can be referred to as a design factor, design factor of safety or required factor of safety.
Safety engineering is an engineering discipline which assures that engineered systems provide acceptable levels of safety. It is strongly related to industrial engineering/systems engineering, and the subset system safety engineering. Safety engineering assures that a life-critical system behaves as needed, even when components fail.
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 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 ...
ISO 3864-3:2012 Part 3: Design principles for graphical symbols for use in safety signs [3] ISO 3864-4:2011 Part 4: Colorimetric and photometric properties of safety sign materials [4] Part 1 explains how to layout the components of safety signage, dictate the color scheme and sizing information.
The Functional safety focus is on ensuring safety critical functions and functional threads in the system, subsystem and software are analyzed and verified for correct behavior per safety requirements, including functional failure conditions and faults and appropriate mitigation in the design. These system safety principles underpinning ...
Automotive safety is the study and practice of automotive design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles. Road traffic safety more broadly includes roadway design.
