How long must testing records for an air pressure maintenance device be retained?

The retention period for testing records for an air pressure maintenance device is crucial for ensuring compliance with inspection, testing, and maintenance regulations. According to NFPA (National Fire Protection Association) standards and industry practices, maintaining records for a minimum of one year aligns with the requirement to monitor and verify the functionality and reliability of these systems over time.

Keeping records for one year provides sufficient time to track performance trends, address any issues that may arise during the operational period, and ensure that routine inspections and tests have been appropriately conducted. This duration supports accountability and can be essential during audits or inspections by fire marshals or regulatory bodies.

Longer retention periods, such as two or five years, may apply to different types of records or systems, but according to current standards and practices specific to air pressure maintenance devices, one year is sufficient to ensure compliance and effective maintenance oversight.
