Record the new-looking damage and earlier wear as separate observations, then connect them through dated evidence. A reported impact belongs in the chronology, but it does not automatically explain every feature found afterward. Preserve both the as-found condition and the limits of the available before-and-after record.
Photograph sharp new damage and rounded prior wear separately
Take a blade-wide overview and label the areas that appear newly damaged, the areas with rounded wear and any locations whose timing is unclear. Use neutral feature descriptions such as chipped corner, rounded edge or missing section. Avoid relying on terms like “fresh fracture” unless the investigator has confirmed what the surface represents.
Include close-ups with a scale and viewing direction. Keep differences in lighting visible: a bright surface can look newer than a darker one without establishing its age. If loose pieces are recovered, label their recovery location and time. Do not assume that every piece near the machine belongs to this blade or this incident.
The incident-reporting guide covers the complete claim process. This report has a more specific job: prevent mixed-age evidence from being collapsed into one damage description before the cause and scope have been assessed.
Build a timeline from prior inspection images and the incident report
Find the latest inspection that actually shows the relevant positions. Record its date, what it visibly establishes and what it cannot resolve. An overall photograph may show that the blade was installed but lack the detail needed to establish the earlier condition of a particular corner. Treat that limitation honestly rather than calling the image proof that the whole edge was undamaged.
Record the impact as reported: time, approximate location, identified object if known and any immediate change in operation. Distinguish the operator's recollection from an event logged contemporaneously. If the edge was inspected only at the end of the shift, state that the discovery followed the event rather than claiming the feature was observed at impact.
Add subsequent movement, removal, cleaning and repair to the timeline. The applicable equipment instructions control safe inspection and repair; gathering better evidence should never require recreating an impact or returning unsafe equipment to work.
Describe observed changes without assigning fault before investigation
Send the record with three clear categories: condition established before the event, condition first documented afterward, and timing unresolved. These categories are useful even if the ultimate causal explanation remains open. They help the investigator decide whether material examination, installation records or further operator clarification would add value.
Keep service exposure and previous maintenance in the pack. The Clear Roads evaluation framework is relevant to interpreting performance in context, but no general field-study result determines responsibility for a particular impact complaint. An observed change after an event supports a question about that event, not an automatic conclusion about every damaged area.
When asking about replacement wear parts, separate the immediate restoration requirement from the review of pre-existing wear and incident damage. Preserve the retained blade until handling and examination are agreed. A final report can legitimately allocate some observations to known earlier condition while leaving others unresolved; it need not offer one simple story for the entire edge.
