16.8
17.0
19.2

21.0

Answer 1

The Total Recordable Incident Rate (T.R.I.R.) for Ajax Construction Company is calculated by combining the number of lost-time injuries and medical-only cases to determine total incidents, then factoring in the total hours worked by the company's employees. Using the TRIR formula, the rate is determined to be 17.0.

Step-by-step explanation:

To calculate the Total Recordable Incident Rate (T.R.I.R.) for Ajax Construction Company, we need to apply the formula that takes into account the number of recordable incidents, the number of hours worked, and a standardized factor (usually 200,000 representing 100 employees working 40 hours a week for 50 weeks). Firstly, let's combine the total incidents, which include both lost-time injuries and medical only cases, giving us a total of 15 (lost-time) + 36 (medical only) = 51 incidents. Then, we will calculate the total hours worked by 300 workers over the year: 300 workers × 40 hours/week × 50 weeks/year = 600,000 hours worked.

Now, we apply the TRIR formula:
(Number of Incidents × 200,000) / Total Hours Worked
(51 incidents × 200,000) / 600,000 hours worked = 17.0

So, the Total Recordable Incident Rate (T.R.I.R.) for Ajax Construction Company is 17.0.
