The design should incorporate special sensors for hazard detection. In the example, the sensor is a thermometer.
A hardware fault is an event of a system component changing from functional to mal-functional.
Typically, hardware faults cannot be prevented by design. What we can do is reduce their likelihood, and to mitigate their risks.
Protection design is a three stage procedure: first we need to provide immediate aid to enable continuous operation, then we need to fix or replace the spoiled component, and finally we need to reconstruct normal operation.
A key concept emerging from the analysis of celebrated accidents is that of latent hazard s. A latent hazard is defined as an hazard of which the operators are not aware. A main goal and challenge in resilience assurance is to prevent latent hazards, namely, to enable and enforce the operators awareness of hazards.
Fault detection is based on special resilience add-ons.
