Incident Rate Calculations Flashcards

A company wants to compare its safety performance to the BLS national average. The most appropriate benchmark source is:

Answer: BLS Survey of Occupational Injuries and Illnesses (SOII)

The BLS SOII provides industry-specific TCIR and DART rates by NAICS code, which is the standard benchmark for comparing employer performance.

An employee is injured and placed on light duty for 15 days. How should those 15 days be classified on the OSHA 300 log?

Answer: Days of job transfer or restriction

Light duty that restricts the employee's normal job functions is classified as job transfer or restriction, not days away from work.

Which of the following would NOT be counted in total hours for the TCIR denominator?

Answer: Both A and B

Only actual hours worked are included; paid sick leave, vacation, holidays, and other non-worked paid time are excluded from the denominator.

A manufacturing plant has a TCIR of 4.2. The BLS industry average is 3.1. This indicates:

Answer: The plant has a higher injury rate than the industry average

A TCIR of 4.2 versus a benchmark of 3.1 means the plant has 35% more recordable injuries per 100 workers than the industry average — worse performance.

The Severity Rate formula uses which unit instead of recordable cases?

Answer: Total days charged

Severity Rate = (Total days charged × 200,000) / Total hours worked, using charged days to measure impact rather than simply counting incidents.

An employer with 250 employees (all full-time, 2,000 hours/year) had 4 recordable cases. What is the TCIR?

Answer: 3.2

TCIR = (4 × 200,000) / (250 × 2,000) = 800,000 / 500,000 = 1.6; wait — 800,000/500,000 = 1.6, so the correct answer is 1.6.

Which OSHA form is used to summarize annual injury and illness totals and must be posted from February 1 to April 30?

Answer: OSHA 300A

The OSHA 300A Summary must be certified by a company executive and posted in a visible location from February 1 through April 30 each year.
