Which of the following would not breach the vacuum system?

Addition of a system component
Removal of a system component
Replacement of a system component with an identical one
Testing a system component with leak detection solution

The correct answer is: Replacement of a system component with an identical one

The option indicating the replacement of a system component with an identical one would not breach the vacuum system because it involves substituting a part with a component that has the same specifications and functionality. This action maintains the integrity of the system, ensuring that the overall vacuum pressure and operational efficiency remain unchanged. When an identical component is used, it does not introduce any potential points of failure or compromise the system's ability to maintain a vacuum. In contrast, adding or removing system components can create openings in the system that may allow air or other contaminants to enter, which would breach the vacuum. Similarly, testing a component with a leak detection solution generally involves applying a substance that could temporarily disrupt the vacuum integrity, potentially causing a breach. Therefore, replacement with an identical component is a safe action in maintaining the vacuum system’s integrity.
