Understanding the Recordable Injury Frequency Rate (RIFR)

The Recordable Injury Frequency Rate (RIFR), often used interchangeably with the Total Recordable Incident Rate (TRIR), is a standard safety metric established by OSHA. It allows companies to benchmark their safety performance regardless of their size or the total number of employees.

The Standard Formula

RIFR = (Number of Injuries × 200,000) / Total Hours Worked

The 200,000 figure in the formula represents the base for 100 full-time equivalent workers (working 40 hours per week, 50 weeks per year). Using this constant makes it easy to compare a small 20-person shop to a 2,000-person factory on an even playing field.

What Counts as a Recordable Injury?

According to OSHA standards, an injury is generally recordable if it results in any of the following:

• Death
• Days away from work
• Restricted work or transfer to another job
• Medical treatment beyond first aid
• Loss of consciousness
• A significant injury or illness diagnosed by a physician

Realistic Example

Suppose "ABC Manufacturing" had a workforce that logged a total of 450,000 hours over the last year. During that time, they documented 9 recordable injuries. Their calculation would look like this:

(9 injuries × 200,000) / 450,000 hours = 4.0 RIFR

This means for every 100 employees, 4 experienced a recordable injury over the course of the year. This number is then compared to industry averages published by the Bureau of Labor Statistics (BLS) to determine if the company is performing above or below the safety standards for their specific sector.

Why Track This Metric?

1. Internal Benchmarking: Track your progress over several years to see if safety initiatives are actually working.
2. External Comparison: Compare your rates to industry peers or national averages.
3. Insurance Premiums: Many insurance providers look at these rates when calculating workers' compensation premiums.
4. Bidding for Contracts: Many clients require RIFR/TRIR data during the pre-qualification phase of a construction or maintenance contract.
