Guide to OSHA Safety Recordkeeping and Incident Rates
Occupational safety and health compliance is a vital operational benchmark for modern human resources, environment health and safety (EHS) coordinators, and executives. Accurately tracking incidents and calculating rates not only satisfies statutory requirements under 29 CFR Part 1904, but also serves as the primary gauge of an organization’s cultural safety health.
Demystifying Safety Rates: TRIR vs. DART
The Bureau of Labor Statistics (BLS) and OSHA utilize normalized rate models to evaluate company-wide safety independent of company size. This normalization is achieved by pacing cases against a base exposure rate of 200,000 work hours (equivalent to 100 full-time employees working 40 hours per week for 50 weeks in a fiscal year).
- Total Recordable Incident Rate (TRIR): This measures the frequency of all work-related injuries and illnesses that require medical attention beyond basic first aid. It is the primary metric analyzed by external auditors and insurance underwriters.
- Days Away, Restricted, or Transferred (DART) Rate:DART is a subset of TRIR that measures only the more severe incidents — specifically those resulting in lost days, modified duties, or temporary transfers to alternate assignments. A high DART rate is a trailing indicator of serious hazard risks on site.
What is a “Recordable” Case Under 29 CFR 1904.7?
Many safety disputes center on whether a worker’s minor injury is “OSHA Recordable”. For an event to be recordable on Form 300, it must meet three simultaneous tests:
- Employee Relationship:The affected worker must be a formal payroll employee OR a leased/temporary worker whose day-to-day work tasks are actively directed by your management staff. Independent contractors or employees of external partners are registered on their own respective employers’ logs.
- Work-Relatedness: OSHA presumes work-relatedness for any event that takes place in the work environment or results from work-related travel or remote work setups, unless it matches an explicit regulatory exception (e.g., voluntary fitness activity, personal grooming, or eating self-brought food).
- Severity/Outcome: The case must result in one of the following: death, loss of consciousness, days away from work, work restriction, job transfer, or medical treatment beyond first aid.
The Critical Distinction: First Aid vs. Medical Treatment
OSHA maintains a highly specific, exhaustive list of “First Aid” treatments. If an injury is treated ONLY with these designated therapies, it is exempt from recordkeeping:
- Using non-prescription medication at non-prescription strength (even if a doctor suggests it).
- Administering tetanus immunizations.
- Cleaning, flushing, or soaking wounds on the skin surface.
- Using bandages, Gauze, butterfly bandages, or Steri-Strips (sutures, staples, and surgical glue count as medical treatment).
- Hot/cold therapy (heating pads, ice packs).
- Any non-rigid support (elastic wraps, bandages, non-rigid splints).
- Temporary immobilization devices for transport.
- Drilling fingernails or toenails to relieve pressure, or draining fluid from blisters.
- Removing splinters or foreign material from areas other than the eye with simple irrigation, swabs, or tweezers.
- Eye patches or finger guards.
The 2024-2026 OSHA ITA Electronic Filing Requirements
Under OSHA’s updated rules, electronic reporting has expanded. The requirements are based on the peak size of your establishment’s payroll and its industry risk level:
- Fewer than 20 Employees: No routine electronic submission required, although the paper log records must still be kept if not industry-exempt.
- 20 to 99 Employees (High-Hazard): Establishments in specific sectors listed under Appendix A (such as construction, warehousing, hospitals, agriculture, and manufacturing) must electronically submit Form 300A annual summaries once a year.
- 100 to 249 Employees (Extreme High-Hazard): Establishments in the specific high-hazard industries listed in Appendix B must electronically submit Form 300, 301, and 300A annually. This massive requirement ensures OSHA gains deeper visibility into granular injury types.
- 250+ Employees: Any establishment required to keep records with 250+ employees must electronically submit Form 300A. If the industry falls in Appendix B, they must also submit the detailed Form 300 and 301.
