What 29 CFR 1904.41 requires (plain English)
29 CFR 1904.41 is the electronic-submission rule of OSHA recordkeeping. Separate from keeping the records (§§1904.4–1904.33) and from reporting fatalities and severe injuries by phone (§1904.39), it requires certain establishments to electronically submit their injury and illness data to OSHA through the Injury Tracking Application (ITA).
Coverage is by establishment size and industry. Establishments with 250 or more employees at any time during the previous year that are required to keep records must electronically submit their OSHA Form 300A summary; establishments with 20–249 employees in industries designated in the rule's appendix (higher-hazard sectors) must also submit their 300A. Under the 2024 expansion, establishments with 100 or more employees in certain high-hazard industries must additionally submit their more detailed OSHA Form 300 Log and 301 Incident Report data. Submissions are due by March 2 of the year following the year the records cover.
1904.41 exists because the aggregated data is valuable: OSHA uses it to identify establishments and industries with high injury rates, to target inspections and emphasis programs, and (for portions of the data) to make establishment-specific information available. For employers, the obligation is to determine coverage correctly by size and industry and to submit the required forms through the ITA on time: an obligation distinct from, and in addition to, keeping the underlying records.
