1. What is Severity Rate?

The Severity Rate is a safety metric that measures the severity of workplace injuries by calculating the number of lost workdays per 200,000 hours worked. It helps organizations assess the seriousness of injuries and prioritize safety improvements.

2. How Does the Calculator Work?

The calculator uses the Severity Rate formula:

\[ \text{Severity Rate} = \frac{\text{Number of Lost Workdays} \times 200000}{\text{Total Hours Worked}} \]

Where:

Number of Lost Workdays — Total days lost due to workplace injuries
Total Hours Worked — Total hours worked by all employees during the period
200,000 — Base for 100 full-time workers (40 hours/week × 50 weeks/year)

Explanation: The formula standardizes injury severity data to allow comparison across different organizations and time periods.

3. Importance of Severity Rate Calculation

Details: Tracking severity rate helps organizations identify high-risk areas, evaluate safety program effectiveness, and comply with OSHA reporting requirements. A lower severity rate indicates better injury management and workplace safety.

4. Using the Calculator

Tips: Enter the total number of lost workdays and total hours worked by all employees during the reporting period. Ensure accurate data collection for meaningful results.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between severity rate and incidence rate?
A: Incidence rate measures the frequency of injuries, while severity rate measures the seriousness of injuries based on lost workdays.

Q2: What is considered a good severity rate?
A: Lower rates are better. Industry benchmarks vary, but rates below the industry average indicate good safety performance.

Q3: How often should severity rate be calculated?
A: Typically calculated monthly, quarterly, and annually to track trends and identify areas for improvement.

Q4: What types of injuries should be included?
A: Include all work-related injuries that result in lost workdays, as defined by OSHA recordkeeping requirements.

Q5: How can organizations reduce their severity rate?
A: Through improved safety training, better equipment maintenance, ergonomic improvements, and prompt medical treatment for injuries.
