Safety self-report (OSHA 300A)
Recordable injury rates the employer filed with OSHA’s Injury Tracking Application. DART covers cases with days away, restricted, or transferred; TRIR is the total recordable case rate.
Reported for 125 average annual employees at this establishment.
Source: OSHA ITA Form 300A (employer self-reported). Rates are per 100 full-time equivalent workers. Establishments below the ~10-FTE threshold are not required to report.
Industry benchmark
BLS rates reflect industry-wide averages. Self-reported figures come from OSHA’s Injury Tracking Application; absence of self-reported data does not necessarily indicate non-compliance — many establishments fall below the ITA reporting threshold.
