1. What is Lost Time Injury Rate?

The Lost Time Injury Rate (LTIR) is a safety metric that shows the number of lost time injuries occurring in a workplace per million hours worked. It's a key indicator of workplace safety performance.

2. How Does the Calculator Work?

The calculator uses the LTIR formula:

Where:

• \( Injuries \) — Number of lost time injuries
• \( Hours \) — Total hours worked by all employees

Explanation: The formula standardizes the injury rate to a common base (1 million hours worked) allowing comparison across different sized organizations.

3. Importance of LTIR Calculation

Details: LTIR helps organizations track safety performance over time, benchmark against industry standards, and identify areas for safety improvement.

4. Using the Calculator

Tips: Enter the total number of lost time injuries and total hours worked by all employees during the measurement period. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What counts as a lost time injury?
A: Any work-related injury that results in time away from work beyond the day of the injury.

Q2: What is a good LTIR value?
A: Lower is better. Industry benchmarks vary, but generally <2.0 is considered good for most industries.

Q3: How often should LTIR be calculated?
A: Typically calculated annually, but can be done quarterly for more frequent monitoring.

Q4: What's the difference between LTIR and TRIR?
A: TRIR (Total Recordable Incident Rate) includes all recordable injuries, while LTIR only counts those resulting in lost work time.

Q5: How do I reduce my organization's LTIR?
A: Implement robust safety programs, hazard identification/control, employee training, and strong safety culture.
