What is the average detection rate for potentially dangerous failures through a well-designed periodic inspection and test?

• A. 100%
• B. 80%
• C. 50%
• D. 0%

Answer: (B)

The average detection rate for potentially dangerous failures through a well-designed periodic inspection and test is often estimated at around 80%. This estimation is based on the understanding that while systematic approaches can catch a majority of potential failures, they do not guarantee the identification of every dangerous failure. Various factors influence this rate, including the effectiveness of the inspection processes, the complexity of the systems being inspected, and the nature of the failures themselves. An 80% detection rate implies that periodic inspections are quite effective yet may still miss some failures. This is realistic in practical applications, where the likelihood of detecting every single potential failure is not guaranteed due to limitations in technology, human error, or unforeseen conditions. In contrast, options of 100% and 0% are not realistic: a 100% detection rate would suggest an infallible inspection process, which does not exist in practice, while a 0% detection rate would indicate that inspections are completely ineffective, which is not the case for well-organized processes. A 50% detection rate would reflect a less robust inspection framework that does not adequately cover the necessary approaches to ensure safety, thus falling short of the expected performance level in functional safety domains.
