Telling the floor above what happened
Turning a week of shifts, incidents and numbers into something the layer above can act on, and deciding what is worth raising at all.

Where this applies
United States, underground coal mines. The regulation says a certified person must record the action taken to correct hazardous conditions and violations found during the pre-shift examination; that all pre-shift and corrective-action records must be countersigned by the mine foreman or equivalent official by the end of their next regularly scheduled shift; and that records may be kept in a secure book or electronically. The corrective-action records were added by the 2012 rule, effective 6 August 2012. One sector; electronic records are allowed, but the signatures stay with people.
What this means
In US coal mining, the shift report that goes up the line must carry the foreman's own countersignature, however it is written.
What it does not yet show
One hazardous sector; it says nothing about weekly summaries or reporting in other workplaces.
What you can check
Open 30 CFR 75.360 (2025 edition on govinfo) and find "shall be countersigned by the mine foreman or equivalent mine official".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
