Risk-based incident classification

SIF Signal.
An ASTM E2920-26 injury & near-miss classifier

Upload your injury log or near-miss export. This tool classifies every record against the ASTM E2920-26 severity framework — Levels 1–4, potential SIFs (pSIF), and SIFRisk conditions — and hands you back a clean spreadsheet. Built to move safety programs from outcome-based recording ("who got hurt?") to risk-based prevention ("who could have died?").

Aligned with ASTM E2920-26 Reflects NSC SIF-prevention guidance Supports ISO 45001 / ANSI/ASSP Z16.1

The E2920-26 framework this tool applies

Level 1 — aSIF

Actual Serious Incident or Fatality. Clear workplace connection with life-ending, life-threatening, or life-altering consequences.

Benchmarkable

Level 2 — Priority

Not an actual SIF, but clear workplace connection with significant consequences. Elevated to a KPI.

Benchmarkable

Level 3 — Regulatory

Cases generally recorded to satisfy OSHA / local law. Not mandatory under the guide, but usually compulsory.

Non-mandatory (guide)

Level 4 — Minor / Near miss

First-aid cases and near-miss incidents that don't meet Level 1–3 severity.

Non-mandatory

pSIF — Potential SIF

Could have been a SIF. Levels 2–4, where SIF-level energy was released and a safeguard held or failed.

Not benchmarked — encourage reporting

SIFRisk — Condition

No incident yet. A person is in the path of the energy and the control is absent, unverified, or defeated. Seeing a hazard from outside the zone is an observation.

Leading indicator
Where SIF risk ends and a pSIF begins Below the X1 thresholds, a Level 2 to 4 incident is not a pSIF. SIFRisk is a condition with SIF-level energy and no incident yet. When that energy is released, a Level 2 to 4 case is a pSIF, controlled if a safeguard held and uncontrolled if it was absent, not followed, or failed. A Level 1 aSIF is always a SIF. THE BASIS, FROM ASTM E2920 Where SIF risk ends and a pSIF begins Below the line. A Level 2–4 incident under the X1 thresholds: falls under 4 ft, vehicles under 15 mph (house rule: under the site speed limit), objects under 40 J. Not a pSIF. SIFRisk. Conditions with SIF-level energy. No incident yet. Inventory it and fix it Incident. SIF-level energy was released, past an X1 threshold pSIF Could have been a SIF · Levels 2–4 Controlled A safeguard held Uncontrolled Absent, not followed, or failed aSIF Level 1 Always a SIF The control didn’t hold. Investigate every one From ASTM E2920-26, sections 3–6 and Appendix X1. Members add stricter house rules on top, never looser.
Definitions summarize the publicly published Scope & Significance sections of ASTM E2920-26. A pSIF is a Level 2–4 case where SIF-level energy was released: controlled when a safeguard held, uncontrolled when it was absent, not followed, or failed. A Level 1 aSIF is always a SIF. E2920 covers injuries & illnesses; companion standards cover non-injury incidents — fire, environmental, business interruption (ASTM E3519) — and SIF risk prioritization & safeguard reduction (ASTM E3529). Purchase the authoritative text: ASTM E2920-26. This tool is an aid for triage and prevention prioritization — not the standard itself, and not a substitute for legally required recordkeeping (e.g., OSHA 300).

Upload your log

Before you upload — please read

  1. Don't upload PII. Strip names, employee IDs, SSNs, and exact addresses first. A description of what happened is all the classifier needs.
  2. Where your data goes. Your file is read in your browser. Only the text of each record is sent through this app’s classify API to Claude (Anthropic) for classification — it is not retained by CompScience. Anthropic does not train its models on data submitted through this system (commercial API / zero data retention for training).
  3. Usage notification. When you run a classification, CompScience is emailed your name and email plus a high-level summary (file name, record counts, level totals). Raw incident text is not included in that email.
  4. This does not replace human judgment. Review every classification for correctness. Take the time to understand ASTM E2920-26 and confirm the results reflect both the standard and your organization's own policies before acting on them.
  5. Beta software. Expect rough edges. Classifications can be wrong — especially on sparse records. Please tell us what broke or what you’d change.

From classification to action

Classifying is step one. Most organizations still don't actively manage SIF risk — they track lagging rates and hope. The highest-leverage move is to work your uncontrolled pSIFs first: those are the close calls where nothing but luck stood between a worker and a life-altering injury — then implement, strengthen, or verify the safeguard that would stop the next one.

Present this to your leadership

Adopting E2920-26 will make your "serious" numbers jump — that's expected, and it's a story leadership needs framed correctly (financial exposure, not just safety culture). CompScience can help you build the business case and stand up the program through a short advisory engagement.

Why CompScience built this

CompScience

AI-driven workers’ compensation & risk operations

Our mission

Prevent 1 million workplace injuries by 2035 — and bring serious injuries and fatalities toward zero.

Most companies still manage safety with lagging rates — OSHA recordables, days away — while the events that actually kill and permanently disable people hide in near misses and high-energy exposures. ASTM E2920-26 finally gives a shared language for aSIFs, pSIFs, and controlled vs. uncontrolled. We built SIF Signal so any safety or risk team can take an injury log and see that picture in minutes — then go work the uncontrolled pSIFs before luck runs out. It’s one more way we put prevention into practice: clearer signal, faster action, fewer SIFs.
