1. What is TRIR?

TRIR (Total Recordable Incident Rate) is a safety metric used to compare injury and illness incidence rates across organizations and industries. It represents the number of recordable incidents per 100 full-time workers during a one-year period.

2. How Does the Calculator Work?

The calculator uses the TRIR formula:

Where:

• \( Recordables \) — Total number of recordable incidents
• \( Hours \) — Total hours worked by all employees
• \( 200000 \) — Base for 100 full-time equivalent workers (working 40 hours per week, 50 weeks per year)

Explanation: The formula standardizes incident rates to allow for meaningful comparisons between organizations of different sizes.

3. Importance of TRIR Calculation

Details: TRIR is a key performance indicator for workplace safety. It helps organizations measure safety performance, identify trends, benchmark against industry standards, and prioritize safety improvements.

4. Using the Calculator

Tips: Enter the total number of recordable incidents and the total hours worked by all employees. Ensure both values are positive numbers, with hours greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What constitutes a recordable incident?
A: Recordable incidents include work-related injuries and illnesses that result in death, days away from work, restricted work, transfer to another job, or medical treatment beyond first aid.

Q2: What is a good TRIR value?
A: Lower values indicate better safety performance. The average TRIR varies by industry, but generally a rate below 3.0 is considered good, while rates below 1.0 are excellent.

Q3: How often should TRIR be calculated?
A: TRIR is typically calculated annually, but many organizations track it quarterly or monthly to monitor trends and implement timely safety interventions.

Q4: Are there limitations to TRIR?
A: While useful, TRIR doesn't capture near misses or the severity of incidents. It should be used alongside other metrics like DART rate and severity rate for a complete safety picture.

Q5: How does TRIR differ from other safety metrics?
A: TRIR measures all recordable incidents, while DART (Days Away, Restricted, or Transferred) rate focuses on more serious incidents that result in time away from work.
