Manufacturing (NAICS 31-33): 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.
Other recordable cases: 1.0. "Not published" means the data does not meet BLS publication guidelines.
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 1.4 recordable cases. With 400,000 hours (about 200 employees) the figure is 5.4.
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.
