Mining, quarrying, and oil and gas extraction (NAICS 21): average TRIR and DART

These are the 2024 private-industry incidence rates from the U.S. Bureau of Labor Statistics, per 100 full-time-equivalent workers. Prequalification forms often ask whether your TRIR and DART are at or below these numbers.

Total recordable case rate (TRIR benchmark)

1.2

DART rate

0.9

Days-away-from-work rate

0.7

Job transfer / restriction rate

0.2

Other recordable cases: 0.3. "Not published" means the data does not meet BLS publication guidelines.

Compare my 3-year TRIR, DART and EMR with NAICS 21

What this means for your prequal form

Worked example: a company in this industry with 100,000 hours worked in a year (about 50 full-time employees) would match the industry average at 0.6 recordable cases. With 400,000 hours (about 200 employees) the figure is 2.4.

TRIR = recordable cases × 200,000 ÷ hours worked. DART = (days-away cases + restricted/transfer cases) × 200,000 ÷ hours worked. Use your OSHA 300A totals for each calendar year.
