8.3 Preparing Preliminary Reports & Deficiency Classification

8.3 Preparing Preliminary Reports and Describing Conditions

Level I technicians prepare preliminary reports under direction. Their value is a reliable factual record: what was inspected or tested, the result, the condition found, immediate communication, and restoration status. The supervisor uses those facts with system knowledge, NFPA 25 definitions, owner procedures, and AHJ requirements to finalize classifications and actions.

Observation before classification

Start with evidence. Identify the exact component and location. State the indicated position, measured pressure, elapsed time, visible damage, signal received, or task that could not be completed. Include the operating condition and units. Then state who was notified and what immediate direction was followed.

Avoid writing a cause that was not established. A lower main-drain full-flow pressure can result from several conditions, including water-supply change, an obstructed or partially closed valve, test differences, or gauge problems. The preliminary report should preserve the numbers and comparable test conditions so the cause can be investigated.

NFPA 25 condition concepts

A noncritical deficiency is a condition that does not have a material effect on the ability of the system or unit to function in a fire but should be corrected. A critical deficiency can materially affect performance but does not rise to the standard's definition of an impairment. An impairment is a condition in which a system or unit cannot perform its intended function.

These categories depend on effect and context. The same visible symptom can have different consequences in different arrangements. The official NFPA 25 material associated with the 2023 edition shows that a full-flow pressure drop exceeding the main-drain threshold can appear in different classification columns depending on the underlying condition. Therefore, do not teach “more than 10 percent always equals critical deficiency.” Record the result, investigate, and classify based on the actual cause and effect.

Similarly, a control valve found closed can create an impairment if it prevents water from reaching protected areas. An improperly positioned but still open valve may be evaluated differently. Report the exact valve, indicated position, system served, and available evidence immediately. Do not silently reposition it without authorization because opening a valve can release water into damaged piping or change system status.

Main-drain example

Suppose the prior comparable full-flow pressure was 60 psi and the current full-flow pressure is 48 psi. The reduction is:

(60 − 48) ÷ 60 × 100 = 20%

NFPA 25 (2023) Section 13.2.2.3 requires the cause to be identified and corrected if necessary when there is a 10 percent reduction in full-flow pressure compared with the original acceptance test or previously performed test. The preliminary entry should include prior and current values, gauges, test setup, time and date, static readings, flow stabilization, restoration, and notifications. It should not invent a cause or final category.

Review and escalation

Immediately elevate conditions that appear to remove or seriously reduce protection: closed supply valves, unavailable water supply, system left out of service, failed restoration, major uncontrolled leakage, or a test showing that a required function did not occur. Follow the impairment plan while the supervisor evaluates the scope. Less urgent deficiencies still require accurate reporting and correction tracking.

Use a review flag for facts that require confirmation, such as an unreadable nameplate, conflicting system sign, missing prior baseline, or uncertain component identity. A question mark is better than fabricated certainty. Provide photographs when allowed and link each image to a location and item.

Maintaining the record trail

Do not erase or overwrite an unfavorable result after repair. Record the initial condition, corrective work by the responsible party, and subsequent retest separately. If you make a clerical error, use the approved correction process so the original and correction remain traceable.

Before submitting the preliminary report, check that all assigned components are accounted for, values have units, abnormal results include prompt notifications, and final system and signal status is documented. Clearly identify tasks not completed. The supervisor should be able to reproduce your reasoning from the recorded observations without calling to ask which valve or gauge you meant.

Exam focus

Choose the answer that preserves evidence. A preliminary report states the measurement, condition, location, notification, and restoration. It does not erase a failed result, assign a universal category before the cause is known, or claim independent authority that the Level I task does not provide.

Supervisor-ready entry

• Exact component, location, condition, measurement, and units.
• Required notification, temporary action, and known system effect.
• Final restoration status and any fact still awaiting qualified classification.
