Executes the accident-statistics pipeline for the risk anchors: - Refresh contactModeEvidence with real Eurostat ESAW figures (dataset hsw_ph3_08, reference year 2023): impact 24.0%/21.4%, struck-by 13.0%/23.8%, sharp 14.5%, trapped/crushed 13.8% (fatal), + new physical/mental-stress mode 24.7% → ergonomic. GT-calibrated tier VALUES unchanged; the real data confirms the ordering. - Add the versioned source document (datasources/esaw_accident_stats_2023.md, ESAW CC BY 4.0 + OSHA public-domain context) that is ingested into the core RAG collection bp_iace_accident_stats for searchable evidence. - Whitelist bp_iace_accident_stats in the RAG search handler so seeding can full-text search the statistics with citation at seed time. Two-layer design: the small license-tagged code table stays the deterministic tier/citation lookup; the RAG holds the searchable source evidence.

Accidents at work — contact mode of injury (EU, 2023)
Canonical, citable source document for the IACE risk-frequency/severity anchors.
This file is the versioned artifact that is ingested into the core RAG
collection bp_iace_accident_stats so seeding can full-text search the evidence
and surface the figure with its citation.

Contact mode of injury — EU shares, 2023
| Contact mode | Non-fatal | Fatal |
|---|---|---|
| Physical or mental stress | 24.7 % | — |
| Impact with a stationary object (victim in motion) | 24.0 % | 21.4 % |
| Contact with a sharp / pointed / rough-coarse agent | 14.5 % | — |
| Being struck by an object in motion / collision | 13.0 % | 23.8 % |
| Being trapped or crushed | — | 13.8 % |
| No contact / no information | 9.6 % | 15.1 % |
Reading: the non-fatal column anchors the frequency / probability tier (W) of a contact mode; the fatal column (and the fatal-vs-non-fatal gap) anchors its typical severity (S). Struck-by and trapped/crushed are comparatively rare among non-fatal but over-represented among fatal accidents — i.e. lower frequency, higher severity.

- 2023: 5,283 fatal work injuries in the US (3.5 per 100,000 FTE workers).
- Most frequently violated standards: Fall Protection, Hazard Communication, Control of Hazardous Energy (Lockout/Tagout).
US BLS CFOI/SOII event-level tables (public domain) are an intended further supplement; the BLS site blocks automated retrieval, so those figures are to be added from a manually downloaded release.
How these numbers are used
- Anchor (ordering): the relative frequency/severity ordering of contact
modes above sets the direction of the W and S tiers in
risk_estimation.go(contactModeTable). - Calibrate (values): tier values are adjusted to BreakPilot ground truth; well-sampled modes use the GT mean, sparse modes use conservative defaults — no overfitting to a small GT sample.
