Flow test results from a private fire service main that do not compare to previous tests are considered a/an _____?

When flow test results from a private fire service main do not correlate with previous tests, it indicates a significant issue that could affect the system's performance in an emergency. This situation is classified as a critical deficiency because it raises immediate concerns about the reliability and integrity of the fire protection system.

Critical deficiencies often require urgent attention and remediation to ensure that the fire protection system operates at its designed capacity during an emergency. These results may highlight potential problems such as obstructions, degradation of the system, or pressure issues that could severely impede water flow during a fire event, thereby jeopardizing safety.

In contrast, other classifications such as non-critical deficiencies or minor deficiencies refer to lesser issues that may not have an immediate or serious impact on the system's operational integrity. Identifying and addressing critical deficiencies is essential for maintaining the effectiveness of fire service mains and ensuring compliance with safety standards.
