The severity rate is a critical metric used to assess the impact of workplace injuries within a company. It specifically measures the seriousness of injuries that lead to lost workdays. The formula for calculating the severity rate involves taking the total number of days away from work due to injuries (DART days) and standardizing that number by multiplying it by 200,000, which represents the number of hours that 100 employees would typically work in a year. This figure is then divided by the total hours worked by all employees over the same period.

This calculation helps organizations understand the severity of injuries in relation to their workforce size and work hours. By using the DART metric, organizations can gain insights into how workplace injuries affect productivity and workforce well-being. It allows for comparisons over time or between different companies, thereby facilitating better safety program planning and implementation.

Other options do not accurately represent the methodology for calculating severity rate. While they may address aspects of workplace safety metrics or injury statistics, they don't align with the accepted formula for assessing severity in the context described.
