What is OSHA TRIR rate?
OSHA TRIR (Total Recordable Incident Rate) measures the number of work-related injuries and illnesses per 100 full-time employees over one year. It's calculated as: (Recordable Incidents × 200,000) ÷ Total Hours Worked.
What is considered a good TRIR rate?
A good TRIR rate depends on industry. The national average is 3.5-4.0, but construction, healthcare, and manufacturing average 4.5-6.0, while professional services average 1.5-2.5.
What counts as a recordable incident for TRIR?
Recordable incidents include work-related deaths, days away from work, restricted work activity, medical treatment beyond first aid, loss of consciousness, and significant injury or illness diagnosed by a physician.
Why is 200,000 used in the TRIR formula?
200,000 represents the hours worked by 100 full-time employees in one year (100 employees × 40 hours/week × 50 weeks/year). This standardizes TRIR across companies of different sizes.
What is the difference between TRIR and DART rate?
TRIR includes all recordable incidents. DART (Days Away, Restricted, or Transferred) counts only more severe cases—injuries causing time away from work or job restrictions.
