Accident and loss statistics: Return to Example 1-1. For parts (b) and (c), the length of time for both the hours-based fatal injury rate and the recordable incidence rate was 1 year. What time period is required for the hours-based fatal injury rate and the recordable incidence rate to be equal to the chemical manufacturing rates?
