Fail-safe and fail-secure are distinct concepts. Fail-safe means that a device will not endanger lives or property when it fails. Fail-secure, also called fail-closed, means that access or data will not fall into the wrong hands in a security failure.
Fail-safe designs are designs that incorporate various techniques to mitigate losses due to system or component failures. The design assumption is that failure will eventually occur but when it does the device, system or process will fail in a safe manner. What is meant by “Safe-Life”?
Sep 21, 2022 · Let’s explore fail safe design principles and some examples further… 1. A few preliminary fail safe concepts. An error (step 1) can lead to a failure (step 2) which can lead to a hazardous situation (step 3) which can lead to personal harm and/or disastrous environmental/economic loss (step 4).
Sep 17, 2023 · What Does Fail-Safe Design Mean? Fail-safe design is an approach to building structures, machinery, and equipment in such a way that they can fail without causing excessive damage or putting people at risk of harm. Preventing failures from occurring altogether would be a preferable outcome.
The fail-safe concept, on the other hand, is based on the argument that even if an individual member of a large structure fails, there should be sufficient structural integrity in the remaining parts to enable the structure to operate safely until the damage is detected and repaired.
Fail-safe design requires that if one part fails, the system does not fail. Fail-safe design recognizes that fatigue cracks may occur and structures are arranged so that cracks will not lead to failure of the structure before they are detected and repaired.
Feb 23, 2011 · In fail-safe design, consider the worst-case scenario if a key part suddenly stopped functioning. If this outcome is intolerable, then safeguards must be engineered to mitigate or prevent that outcome. Designing something to be fail-safe is a challenging thought process but an important one.
