# HSE Incident Rate Calculator

Interactive web calculator for the standard occupational-safety incident-rate metrics:

- **TRIR** (OSHA Total Recordable Incident Rate)
- **LTIFR** (Lost Time Injury Frequency Rate, ILO/HSE)
- **DART** (Days Away, Restricted, or Transferred rate, OSHA)
- **AFR** (Accident Frequency Rate, generic per million hours)
- **Severity Rate** (lost days per million hours)
- **TRIFR** (Total Recordable Injury Frequency Rate)

Each formula links to the canonical authoritative source (OSHA 29 CFR 1904, ILO Resolution III, HSE Methods Statement).
