Calibrated Risk replaces guesswork in Job Hazard Analyses with risk scores grounded in real OSHA enforcement data. Describe a task in plain language. Calibrated Risk identifies the hazards, maps each one to the specific CFR standard that governs it, and scores the risk using actual citation rates and injury outcomes for your industry — not estimates, not ranges, not someone's recollection. DISCLAIMER: Calibrated Risk is an independent, privately developed tool. It is not affiliated with, endorsed by, or authorized by OSHA, the U.S. Department of Labor, the U.S. Census Bureau, or any government agency, and it does not represent any government entity or provide official government services. It analyzes publicly available government data; official sources are listed below. WHAT YOU GET • Hazard identification from a plain-language task description • Every hazard mapped to a specific 29 CFR 1910 or 1926 standard • Citation rates calculated per CFR standard, per NAICS code • Fatality and hospitalization rates from investigated OSHA injury records • Risk levels from Critical to Negligible, with Aggregate Priority Numbers • Hierarchy-of-controls recommendations tied to enforcement data • Residual risk scoring after controls are applied BUILT ON REAL DATA 13.2 million OSHA violation records. 5.1 million inspections. 231,000 investigated injury outcomes. Every score traces back to enforcement history for your specific standard and industry — so when someone asks why a hazard is rated Critical, you have an answer. GOVERNMENT DATA SOURCES All government data is sourced from official U.S. government records: • OSHA inspection & violation records — OSHA Establishment Search: https://www.osha.gov/ords/imis/establishment.html • OSHA enforcement data (bulk downloads) — U.S. Dept. of Labor: https://enforcedata.dol.gov • Severe injury & hospitalization reports — OSHA Severe Injury Reports: https://www.osha.gov/severe-injury-reports • 29 CFR 1910 & 1926 standards — OSHA Law & Regulations: https://www.osha.gov/laws-regs/regulations/standardnumber • Official regulation text — eCFR Title 29: https://www.ecfr.gov/current/title-29 • NAICS industry codes — U.S. Census Bureau: https://www.census.gov/naics FOR SAFETY PROFESSIONALS • Save JHAs to your library and reopen them anytime • Export a complete PDF report with controls, residual risk, and citations • Offline access to your saved JHAs in the field FREE TO TRY Run your first JHA free.

Verdict

The call

The clearest difference is rating: Calibrated Risk at 5.0 against Rock's 4.4. Calibrated Risk also leads on update cadence (every 8 days vs every 3 weeks). Rock's advantage is ratings volume (65 vs 1) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
