1. What is the Lost Work Day Rate?

The Lost Work Day Rate is a safety metric that calculates the frequency of lost time incidents per 200,000 work hours (equivalent to 100 employees working 1 year). It helps organizations measure and compare workplace safety performance.

2. How Does the Calculator Work?

The calculator uses the Lost Work Day Rate equation:

Where:

• \( Lost\ Days \) — Total number of days lost due to work-related injuries or illnesses
• \( Hours \) — Total hours worked by all employees during the period
• \( 200000 \) — Base for 100 employees working 1 year

Explanation: The equation standardizes the rate to allow comparison between organizations of different sizes.

3. Importance of Lost Work Day Rate

Details: This rate is crucial for occupational health and safety management, helping identify trends, evaluate safety programs, and benchmark against industry standards.

4. Using the Calculator

Tips: Enter total lost days (can be decimal for partial days) and total hours worked by all employees during the period. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a good Lost Work Day Rate?
A: Lower rates are better. Industry benchmarks vary, but rates below 1.0 are generally considered good in many industries.

Q2: How does this differ from OSHA's Recordable Incident Rate?
A: The Recordable Incident Rate counts all recordable incidents, while Lost Work Day Rate specifically measures days away from work.

Q3: What time period should be used for calculation?
A: Typically calculated annually, but can be done for any period (monthly, quarterly) for more frequent monitoring.

Q4: Should vacation or sick days be included?
A: No, only days lost due to work-related injuries or illnesses that meet OSHA recordability criteria.

Q5: How can organizations reduce their rate?
A: Through effective safety programs, hazard identification/control, employee training, and strong safety culture.
