What does the OSHA severity rate formula calculate?

• A. S = Total severity incidents / EH x 100,000
• B. S = Lost work days / EH x 200,000
• C. S = Number of injuries / Total work hours
• D. S = Total costs / Total incidents

Answer: (B)

The OSHA severity rate formula specifically measures the impact of workplace injuries in terms of the number of lost workdays per hours worked. By calculating lost workdays divided by employee hours (EH) and then multiplying by a standard factor, typically 200,000, it provides a metric that reflects how serious the injuries are in the context of overall work hours.

This formula is particularly useful for understanding not just how many injuries occurred, but how those injuries have tangible effects on workforce productivity and health. The inclusion of the multiplier (200,000) serves to standardize the rate for comparative purposes across different organizations and industries.

Other options present different formulas that aren't aligned with the OSHA severity rate as defined by the organization. For example, one choice involves total severity incidents which might not focus on lost workdays, while another option computes the number of injuries without considering the relationship to work hours and lost days. Thus, the use of lost workdays in the correct answer provides a critical insight into workplace safety and the consequences of injuries, which is at the heart of safety management and OSHA regulations.
