  7. A safety professional calculates the incident rate for a company with 3 recordable injuries, 100 employees working 40 hrs/week for 50 weeks. What is the TRIR?

    Answer: 3.0

    TRIR = (Number of recordable injuries × 200,000) ÷ total hours worked; (3 × 200,000) ÷ (100 × 40 × 50) = 600,000 ÷ 200,000 = 3.0.
