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]
Effective engineering controls are integral to the original equipment design and work to eliminate or block hazards at the source before they reach workers. They are designed to prevent users from modifying or tampering with the controls and require minimal action from users to function effectively.
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.
Engineering controls for psychosocial hazards include workplace design to affect the amount, type, and level of personal control of work, as well as access controls and alarms. The risk of workplace violence can be reduced through physical design of the workplace or by cameras.
In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
Hazard substitution is a hazard control strategy in which a material or process is replaced with another that is less hazardous. Substitution is the second most effective of the five members of the hierarchy of hazard controls in protecting workers, after elimination.
The phrase crime prevention through environmental design (CPTED) was first used by C. Ray Jeffery, a criminologist from Florida State University. The phrase began to gain acceptance after publishing his 1971 book of the same name. Jeffery's work was based on the precepts of experimental psychology represented in modern learning theory. (Jeffery ...
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.
