1. What is the Lost Day Incident Rate?

The Lost Day Incident Rate is a safety metric that measures the number of lost work days per 200,000 work hours. It helps organizations assess workplace safety performance and compare it across different periods or companies.

2. How Does the Calculator Work?

The calculator uses the Lost Day Incident Rate equation:

Where:

• \( Lost\ Days \) — Total days lost due to work-related injuries or illnesses
• \( Hours \) — Total hours worked by all employees during the period
• \( 200000 \) — Base for 100 full-time workers (assuming 2000 hours/year/worker)

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

3. Importance of Lost Day Incident Rate

Details: This metric is crucial for workplace safety management, regulatory compliance, and benchmarking safety performance against industry standards.

4. Using the Calculator

Tips: Enter total lost days and total hours worked. Both values must be positive numbers (hours must be greater than zero).

5. Frequently Asked Questions (FAQ)

Q1: What counts as a lost day?
A: A lost day is any day an employee is unable to work due to a work-related injury or illness beyond the day of the incident.

Q2: Why use 200,000 hours as the base?
A: This represents 100 full-time employees working 40 hours/week for 50 weeks/year, allowing standardized comparison.

Q3: How does this differ from OSHA recordable rate?
A: The Lost Day Rate specifically measures days away from work, while OSHA recordable includes all recordable incidents.

Q4: What is a good Lost Day Incident Rate?
A: Lower is better. Industry benchmarks vary, but rates below 1.0 are generally considered good in most industries.

Q5: How often should this be calculated?
A: Typically calculated annually, but can be done quarterly or monthly for more frequent monitoring.
