TRIR Calculator — Total Recordable Incident Rate
POR Equipe editorial RiskoPilot · REVISADO EM 2026-07-11
TRIR (Total Recordable Incident Rate) is calculated as (number of OSHA-recordable incidents × 200,000) ÷ total hours worked. The 200,000 constant represents 100 full-time workers × 40 hours × 50 weeks. A TRIR of 1.0 means one recordable per 100 FTEs per year. US industry averages sit at 2.7 (BLS 2022); world-class programmes achieve below 0.5.
Calculadora TRIR
Total Recordable Incident Rate — number of recordable injuries per 100 full-time equivalent workers per year.

(Recordable incidents × 200,000) ÷ Total hours worked
Exemplo: 3 × 200,000 ÷ 500,000 = 1.20

What counts as an OSHA recordable?
Under 29 CFR 1904, an injury or illness is recordable if it results in: death, days away from work, restricted work or job transfer, medical treatment beyond first aid, loss of consciousness, or a significant injury diagnosed by a healthcare professional. First-aid-only cases and near-misses are not recordable but should be tracked as leading indicators.
Why TRIR alone is a poor safety indicator
TRIR is a lagging indicator — it counts injuries that already happened. It can be gamed (reclassifying cases as first-aid, discouraging reporting) and it correlates weakly with the probability of the next fatality. Best-practice HSE programmes pair TRIR with leading indicators: near-miss reporting rate, GFT drift, CAPA close rate, safety observations per FTE. See Tripod Beta and BowTie analysis for the methodologies that surface latent risk.
Benchmarks by industry (BLS 2022, US)
Private industry overall: 2.7. Manufacturing: 3.2. Construction: 2.4. Mining, quarrying and oil & gas extraction: 1.2. Utilities: 1.5. Transportation and warehousing: 4.6. Retail trade: 3.6. Healthcare and social assistance: 5.5. Rates outside your industry benchmark by more than 30% are a flag — either your reporting culture is weaker than peers, or your management system is genuinely under-performing. Investigation methodology tells you which.
