The Error Codes That Exposed My Data Problems
My first pass looked fine on screen, then failed in validation. These were the exact log lines that sent me back to root cause.
[ITA_CHECK] E_DATE_042: expected YYYY-MM-DD, got 02/31/2025 [ITA_CHECK] E_CASE_107: case_status value 'restrictedduty' not in enum [SYNC] HTTP 400 Bad Request: establishment_naics is required [QA] WARN_DUP_009: incident_id repeated in shift handover log
Personal Experience #1: One Typo, Four Hours Lost
Pro Tip: If your incident count matches but category totals do not, check enum normalization before checking formulas.
My 7-Step Debug Sequence
- Freeze edits and export one immutable snapshot.
- Validate date format, enum values, and required IDs first.
- Run duplicate checks across shift, medical, and supervisor logs.
- Cross-check heat cases against your Heat Stress Scheduler records.
- Reconcile confined-space incidents with your Gas Monitor Log.
- Compare record totals with your ITA recovery checklist.
- Submit once, then archive the correction trail as evidence.
| Debug approach | Typical time per issue | Failure pattern | Audit confidence |
|---|---|---|---|
| Ad-hoc spreadsheet edits | 15-20 min | New errors introduced during fixes | Low |
| Manual checklist only | 8-12 min | Missed duplicates across sources | Medium |
| Web Ocean structured log flow | 3-5 min | Low with locked formats and timestamps | High |

Personal Experience #2: Date Parsing Was the Real Culprit
Pro Tip: Build one pre-submit validator script and run it locally before every upload window.
The Patch That Stopped Repeat Failures
I added a guardrail layer before export. It blocks bad rows instead of passing them downstream.
function normalizeCase(row: CaseRow): CaseRow {
return {
...row,
incident_date: toISODate(row.incident_date),
case_status: normalizeEnum(row.case_status),
establishment_naics: row.establishment_naics?.trim() || 'UNKNOWN',
};

My Opinion After Doing This Repeatedly
Safety data quality is not a software problem alone. It is an operations discipline. If teams log events late or loosely, no dashboard can save the final export.
What works is a simple loop: structured inputs, fast validation, and one owner for final signoff.
