Frequently Asked Questions
Frequently asked questions about PlainSafetyScore employer safety grades, OSHA data, and how injury rates are calculated.
Common questions about employer safety grades, OSHA data, and how we calculate injury rates.
What does the safety grade mean?
The grade compares an employer's Total Case Rate (TCR) - a standard OSHA injury frequency metric, against the Bureau of Labor Statistics industry average for their sector. Grade A means an employer's injury rate is 50% or less of the industry average; Grade F means it is more than double the industry average.
Where does the injury data come from?
All data comes from OSHA's Injury Tracking Application (ITA), which collects annual 300A summary submissions from employers with 20+ employees in high-hazard industries. We process ITA data for calendar years 2016–2024.
Are all employers required to submit ITA data?
No. OSHA requires 300A electronic submissions only from establishments with 20 or more employees in high-hazard NAICS sectors. Smaller employers and those in low-hazard industries are not represented in this database.
Why does the same employer show different rates each year?
Injury rates naturally vary year to year based on workforce size, operational changes, and statistical fluctuation. The employer's profile page shows trends across all available years so you can distinguish a pattern from an anomaly.
What is Total Case Rate (TCR)?
TCR is OSHA's standard formula for comparing injury frequency across employers of different sizes: (Total Cases / Hours Worked) × 200,000. The multiplier of 200,000 represents 100 full-time employees working 40 hours a week for 50 weeks a year, allowing rates to be compared on a per-100-employees basis.
Can I use this data to file an OSHA complaint?
This site is for informational purposes only. To file a workplace safety complaint, visit osha.gov directly or call 1-800-321-OSHA. PlainSafetyScore is not affiliated with OSHA.
How often is the database updated?
OSHA releases updated ITA data annually, typically 12–18 months after the filing year ends. We update our database when new annual data becomes available. The current database covers 2016–2024.
Why is my employer not listed?
Only establishments with 20+ employees in high-hazard NAICS sectors that filed with OSHA ITA are included. Your employer may be below the threshold, in a low-hazard industry, or have filed under a slightly different name. Try searching with just the company name without suffixes like Inc or LLC.
