What maintenance action is crucial for the safety of low pressure systems?

Inspecting for leaks is a crucial maintenance action for the safety of low-pressure systems. Leaks can lead to the unsafe release of gases or fluids, which may present serious hazards, including fire, explosion, or environmental contamination. Regular inspections help identify potential leak sources, enabling timely repairs and ensuring the system operates safely and efficiently.

Without diligent leak inspection, even small leaks can escalate into significant safety issues over time, emphasizing the importance of this maintenance action in preventing accidents and ensuring compliance with safety regulations. The other options do not contribute meaningfully to the safety of low-pressure systems; for instance, changing paint color has no bearing on system integrity, and leaving a system unused or reconfiguring it without addressing leaks could still pose serious risks.
