A safety critical system is one that must function correctly to avoid human injury, human death, damage to property, financial loss, damage to the natural environment, or devastating systemic effects (such as a catastrophic drop in stock market prices). A system is judged to be safety critical when its use involves risk (a potential that a mishap could occur, with severe consequences). Most safety-critical systems are designed to assure the safe use of systems involving a hazard, a state or condition in which unsafe use of the system will inevitably result in a mishap; for example, a train moving at high speed poses a hazard. Most hazards are caused by the use of potentially dangerous or lethal amounts of energy, such as the potential kinetic energy of a train moving at high speed. See availability, fault tolerance, hazard, mishap, risk.

Safety-critical systems, also called life-critical systems, are computer systems that can result in injury or loss of life if it fails or malfunctions. These systems can also cause harm to other equipment or the environment in the event of failure.

Importance:
Safety critical systems (SCS) are systems designed with the intent of curbing the effects of an accident from a hazardous event. This can be implemented in the aviation industry, the medical profession, nuclear testing, even the Financial sector, as there could be deaths stemming from financial loss too. It is an application where human safety depends on the correct usage of the software program. Safety Engineering emerged in the 1950's and 1960's to help control hazards that emerged from potentially dangerous missile and rocketry projects, and has only grown as more technologies rely on computers. It is important that in these systems, safety is designed into the product rather than it being an afterthought. Simplifying these types of systems is bad as it increases the opportunity for a single component’s malfunction to cause a system wide failure. Small errors in a system can rapidly develop into a system wide failure that creates hazards. In many ways it can be difficult for people to decide when these systems become truly safe enough for widespread use.

A safety-critical system is one that has to work properly to prevent human harm, human death, property damage, financial loss, environmental harm, or severe systemic impacts (such as a catastrophic drop in stock market prices). When using a system poses risk, it is said to be safety-critical (a potential that a mishap could occur, with severe consequences). A train traveling at a fast speed, for example, poses a hazard. Most safety-critical systems are created to ensure the safe use of systems involving a hazard, a state or circumstance in which hazardous use of the system will unavoidably end in an accident. The majority of risks result from the usage of potentially harmful or fatal amounts of energy, like the potential kinetic energy of a train traveling quickly. View hazards, accidents, risk, fault tolerance, and availability.

Computer systems that, if they malfunction or fail, could cause injury or even death are known as safety-critical systems. In the event of failure, these systems may harm the environment or other pieces of equipment.

Safety-critical systems are those systems whose failure could result in loss of life, significant property damage or damage to the environment. There are many well-known examples in application areas such as medical devices, aircraft flight control, weapons and nuclear systems.

Why it is important to learn?:

Safety critical systems (SCS) are systems designed with the intent of curbing the effects of an accident from a hazardous event. This can be implemented in the aviation industry, the medical profession, nuclear testing, even the Financial sector, as there could be deaths stemming from financial loss too. It is an application where human safety depends on the correct usage of the software program. The software or the hardware must not contribute to the cause of the accident or escalate the accident, which is usually unsafe. Safety Engineering emerged in the 1950's and 1960's to help control hazards that emerged from potentially dangerous missile and rocketry projects, and has only grown as more technologies rely on computers.  It is important that in these systems, safety is designed into the product rather than it being an afterthought.  Simplifying these types of systems is bad as it increases the opportunity for a single component’s malfunction to cause a system wide failure.  Small errors in a system can rapidly develop into a system wide failure that creates hazards.  In many ways it can be difficult for people to decide when these systems become truly safe enough for widespread use.

Safety-critical systems are those systems whose failure could result in loss of life, significant property damage or damage to the environment.

It deals to reduce/overcome 

  • death or serious injury to people
  • loss or severe damage to equipment/property
  • environmental harm

There are many well-known examples in application areas such as medical devices, aircraft flight control, weapons and nuclear systems.

Examples of safety-critical systems

  • Circuit breaker.
  • Emergency services dispatch systems.
  • Electricity generation, transmission and distribution.
  • Fire alarm.
  • Fire sprinkler.
  • Fuse (electrical)
  • Fuse (hydraulic)
  • Life support systems.

Safety-critical systems in SE

Software engineering for safety-critical systems is particularly difficult. There are three aspects which can be applied to aid the engineering software for life-critical systems.

  • First is process engineering and management.
  •  Secondly, selecting the appropriate tools and environment for the system. This allows the system developer to effectively test the system by emulation and observe its effectiveness. 
  • Thirdly, address any legal and regulatory requirements, such as FAA requirements for aviation. By setting a standard for which a system is required to be developed under, it forces the designers to stick to the requirements.

Re: Answer the question

by Tariqul Islam -
System Safety is the avoidance of hazards or any condition that threatens the safety of any users. The rate of occurrence and the severity of these hazards factors into how much risk can be tolerated. A hazard can be anything that can lead to an accident, develop into an accident, or anything likely to become dangerous when interacted with. If there is significant risk due to severity or frequency of a particular hazard than risk reduction measures must be implemented in order for a risk to become tolerable. [5]

Safety Engineering emerged in the 1950's and 1960's to help control hazards that emerged from potentially dangerous missile and rocketry projects, and has only grown as more technologies rely on computers. It is important that in these systems, safety is designed into the product rather than it being an afterthought.

The dependability of a system reflects the user's degree of trust in that system. Safety-critical systems are systems where a failure could lead to loss of life or significant damage to property or the environment

Safety-Critical Applications:-
A safety critical system is one that must function correctly to avoid human injury, human death, damage to property, financial loss, damage to the natural environment, or devastating systemic effects (such as a catastrophic drop in stock market prices). A system is judged to be safety critical when its use involves risk (a potential that a mishap could occur, with severe consequences). Most safety-critical systems are designed to assure the safe use of systems involving a hazard, a state or condition in which unsafe use of the system will inevitably result in a mishap; for example, a train moving at high speed poses a hazard. Most hazards are caused by the use of potentially dangerous or lethal amounts of energy, such as the potential kinetic energy of a train moving at high speed. See availability, fault tolerance, hazard, mishap, risk.

Importance To Learn:-
Safety critical systems (SCS) are systems designed with the intent of curbing the effects of an accident from a hazardous event. This can be implemented in the aviation industry, the medical profession, nuclear testing, even the Financial sector, as there could be deaths stemming from financial loss too. It is an application where human safety depends on the correct usage of the software program. Safety Engineering emerged in the 1950's and 1960's to help control hazards that emerged from potentially dangerous missile and rocketry projects, and has only grown as more technologies rely on computers. It is important that in these systems, safety is designed into the product rather than it being an afterthought. Simplifying these types of systems is bad as it increases the opportunity for a single component’s malfunction to cause a system wide failure. Small errors in a system can rapidly develop into a system wide failure that creates hazards. In many ways it can be difficult for people to decide when these systems become truly safe enough for widespread use.
So that is why we can say that safety-critical applications are very important to learn.

As our society becomes more automated and technology efficient, the need to implement safe engineering solutions become paramount. Whilst real-time machine learning is being championed to remove any technological barriers, its successful realisation is inevitably hindered by computational requirements, model quality assurance and justification of resource costs. Yet, due to recent industrial drive, the field is moving quickly with unprecedented interest from several technology organisations, academic disciplines, and even the general public. Machine learning is enabling an array of real-world commercial products and services that were not technologically feasible before and hence can prove useful for safety–critical applications.

Safety-critical systems, also called life-critical systems, are computer systems that can result in injury or loss of life if it fails or malfunctions. These systems can also cause harm to other equipment or the environment in the event of failure.

A safety-critical function is either a “must-work” function or a “must-not-work” function. A must-work-function is an active function vital for keeping the crew alive. A must-not-work function is instead a function that if operated inadvertently or untimely (e.g., propulsion ignition, or access to a live high-power laser) can kill or injure the crew, or cause damages. A function may be a “must-not-work” function for some periods of a mission and a “must-work function” for remaining time. A system function may not be safety critical yet include some inherent hazards such as high voltages, high temperature, toxic compounds, etc. For example, a microgravity experiment using a metal melting furnace.

A failure consists of a function or specified service of a system, device, software, or system operator ceasing or deviating from specification. A fault is instead an incorrect state of hardware or software resulting from failures of components, functional upsets, operator error, or incorrect design. Faults include failures of system elements.

“Fault/Failure Tolerance” is the ability to operate/survive in the presence of faults or failures. “Fault/Failure Avoidance” consists in obviating or mitigating the potential for faults/failures through screening processes (e.g., removing flammable materials), safety factors, and robust design (e.g., derating of components) (Miller et al
