• A. Frequency rate
• B. Severity rate
• C. Incidence rate
• D. Lost-time rate

Answer: (B)

Severity rate measures how serious injuries are by combining the full burden of each incident: the financial/claims charges for deaths and permanent disabilities plus the actual days workers are disabled by temporary injuries during the period. This emphasizes the impact and seriousness of injuries, not just how many occur. In contrast, a frequency or incidence measure looks at how many injuries happen per exposure (like hours worked), and a lost-time rate focuses on injuries that cause workers to miss time. The given description matches severity rate because it sums both the outcomes (deaths and permanent disabilities) and the duration of temporary disabilities, reflecting overall injury impact.
