2. Safety instrumented system - Wikipedia

   en.wikipedia.org/wiki/Safety_instrumented_system

   In functional safety a safety instrumented system (SIS) is an engineered set of hardware and software controls which provides a protection layer that shuts down a chemical, nuclear, electrical, or mechanical system, or part of it, if a hazardous condition is detected.

3. Safety management system - Wikipedia

   en.wikipedia.org/wiki/Safety_management_system

   An occupational safety management system (OSMS) is a management system designed to manage occupational safety and health risks in the workplace.If the system contains elements of management of longer-term health impacts and occupational disease, it may be referred to as a occupational safety and health management system (OSHMS) or occupational health and safety management system (OHSMS).

4. Safety integrity level - Wikipedia

   en.wikipedia.org/wiki/Safety_integrity_level

   These lead to such erroneous statements as the tautology "This system is a SIL N system because the process adopted during its development was the standard process for the development of a SIL N system", or use of the SIL concept out of context such as "This is a SIL 3 heat exchanger" or "This software is SIL 2". According to IEC 61508, the SIL ...

5. Safety-critical system - Wikipedia

   Examples [1] of safety-critical systems. From left to right, top to bottom: the glass cockpit of a C-141 , a pacemaker , the Space Shuttle and the control room of a nuclear power plant . A safety-critical system [ 2 ] or life-critical system is a system whose failure or malfunction may result in one (or more) of the following outcomes: [ 3 ] [ 4 ]

6. Process plant shutdown systems - Wikipedia

   en.wikipedia.org/wiki/Process_plant_shutdown_systems

   Although functionally separate, process control and shutdown systems are usually interfaced under one system, called an integrated control and safety system (ICSS). Shutdown systems typically use equipment that is SIL 2 certified as a minimum, whereas control systems can start with SIL 1. SIL applies to both hardware and software requirements ...

7. High-integrity pressure protection system - Wikipedia

   en.wikipedia.org/wiki/High-integrity_pressure...

   A high-integrity pressure protection system (HIPPS) is a type of safety instrumented system (SIS) designed to prevent over-pressurization of a plant, such as a chemical plant or oil refinery. The HIPPS will shut off the source of the high pressure before the design pressure of the system is exceeded, thus preventing loss of containment through ...

8. Functional safety - Wikipedia

   en.wikipedia.org/wiki/Functional_Safety

   Functional safety is becoming the normal focused approach on complex software intensive systems and highly integrated systems with safety consequences. The traditional software safety tasks and model based functional safety tasks are performed to provide objective safety evidence that the system functionality and safety features perform as ...

9. System safety - Wikipedia

   en.wikipedia.org/wiki/System_safety

   The system safety concept helps the system designer(s) to model, analyse, gain awareness about, understand and eliminate the hazards, and apply controls to achieve an acceptable level of safety. Ineffective decision making in safety matters is regarded as the first step in the sequence of hazardous flow of events in the "Swiss cheese" model of ...
