LTIFR = (Number of LTIs × 1,000,000) / Total Man-Hours Worked

📘 LTIF – Lost Time Injury Frequency Rate

🔎 What is LTIF?

LTIF stands for Lost Time Injury Frequency Rate. It is a standardized measure of how often lost-time injuries (LTI) occur per million man-hours worked.

🧮 LTIF Formula:

LTIF = (Number of LTIs × 1,000,000) / Total Man-Hours Worked

This helps compare safety performance across projects, industries, and time periods.

✅ Example: No LTIF (Zero Injury)

  • 👷 Number of LTIs = 0
  • 🧮 Total Man-Hours Worked = 120,000

Calculation:
LTIF = (0 × 1,000,000) / 120,000 = 0.00

🎉 Excellent Safety Performance — No Lost Time Injuries

📋 Benefits of Zero LTIF:

  • 🏆 Strong HSE reputation
  • ✅ Easier ISO certification or client approval
  • 📉 Lower insurance costs
  • 📈 Improved productivity & morale

📌 Best Practices to Maintain Zero LTIF:

  • 🧰 Regular toolbox talks
  • 🎯 Job hazard analysis (JHA)
  • 🧑‍🏫 Safety inductions & retraining
  • 🔍 Reporting and learning from near misses

🙋‍♂️ How to Use This LTIFR Calculator Tool?

Using the LTIFR (Lost Time Injury Frequency Rate) calculator is simple:

  1. Enter the number of Lost Time Injuries (LTIs) that occurred on your site or project.
  2. Input the total man-hours worked by all employees during the time period.
  3. Click “Calculate LTIFR” — the tool will instantly give you the LTIFR value per million man-hours.

💡 Example:
If your site had 2 LTIs and worked 400,000 man-hours:
LTIFR = (2 × 1,000,000) ÷ 400,000 = 5.00

🎯 Why Use This Tool?

  • ✅ Standardized Reporting: LTIFR is required in safety reports, audits, and ISO documentation.
  • 📊 Track Performance: Helps monitor safety trends across sites or time periods.
  • ⚠️ Identify Risks: High LTIFR alerts management to increase safety measures.
  • 🏆 Showcase Safety Culture: A low or zero LTIFR reflects well in tenders and client meetings.

👷‍♀️ Who Should Use This Tool?

This tool is ideal for:

  • HSE Managers & Safety Officers
  • Construction & Engineering Project Leads
  • Site Supervisors & Contractors
  • HR and Compliance Teams
  • Anyone involved in workplace health and safety
