What should be done with the inspection paperwork after inspecting the CO2 system?

Filing a maintenance report with the owner after inspecting the CO2 system is essential for several reasons. This report serves as a formal record of the inspection findings, any maintenance performed, and recommendations for future actions. It ensures that the owner is informed about the current condition of the system and any potential issues that may need addressing, thus facilitating better decision-making regarding maintenance and safety.

Furthermore, having a detailed maintenance report on file helps in maintaining compliance with regulatory standards and informs the owner of the system’s operational status. This documentation is valuable not only for current maintenance needs but also for future inspections and assessments, as it provides a historical context for the system's performance and any corrective actions previously taken.

The other options would typically not meet the compliance and accountability standards required for maintaining and operating CO2 systems effectively. Keeping inspection records is crucial for safety and operational reliability, making proper documentation a priority.
