It became clear in the early 2000s that many products being used in safety critical applications had mechanical components. An FMEDA done without considering these mechanical components was incomplete, misleading, and potentially dangerous. The fundamental problem in using the FMEDA technique was the lack of a mechanical component database that ...
This cover of I, Robot illustrates the story "Runaround", the first to list all Three Laws of Robotics.. The Three Laws of Robotics (often shortened to The Three Laws or Asimov's Laws) are a set of rules devised by science fiction author Isaac Asimov, which were to be followed by robots in several of his stories.
If and when a "fail-safe" system fails, it remains at least as safe as it was before the failure. [1] [2] Since many types of failure are possible, failure mode and effects analysis is used to examine failure situations and recommend safety design and procedures. [3] Some systems can never be made fail-safe, as continuous availability is needed.
Fail-deadly operation is an example of second-strike strategy, in that aggressors are discouraged from attempting a first strike attack. Under fail-deadly nuclear deterrence, policies and procedures controlling the retaliatory strike authorize launch even if the existing command and control structure has already been neutralized by a first strike.
Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost over ...
“Instilling a blanket ‘dangerous world’ philosophy into our kids’ hearts and minds won’t serve them well in the future,” Reynolds says. She reiterates that communication is imperative.
Risk assessment can also be made on a much larger systems theory scale, for example assessing the risks of an ecosystem or an interactively complex mechanical, electronic, nuclear, and biological system or a hurricane (a complex meteorological and geographical system).
Unlike ATEX which uses numbers to define the safety "Category" of equipment (namely 1, 2, and 3), the IEC continued to utilise the method used for defining the safe levels of intrinsic safety namely "a" for zone 0, "b" for zone 1 and "c" for zone 2 and apply this Equipment Level of Protection to all equipment for use in hazardous areas since ...
