COSS Incident Rate Calculations 3

Question 1

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

Accepted Answer

BLS Survey of Occupational Injuries and Illnesses (SOII)

Answer

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

Question 2

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

Accepted Answer

Days of job transfer or restriction

Answer

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

Question 3

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

Accepted Answer

Both A and B

Answer

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

Question 4

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

Accepted Answer

The plant has a higher injury rate than the industry average

Answer

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.

Question 5

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

Accepted Answer

Total days charged

Answer

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