OSHA 300 Log
Last reviewed · By Chad Griffith
The OSHA 300 Log (Form 300, 'Log of Work-Related Injuries and Illnesses') is the workplace recordkeeping document required by OSHA under 29 CFR Part 1904 for most employers with more than 10 employees in non-exempt industries. Each work-related injury or illness meeting recording criteria (death, days away from work, restricted activity, medical treatment beyond first aid, loss of consciousness, or specific diagnosed conditions) must be logged within 7 calendar days. The annual summary (Form 300A) must be posted in the workplace from February 1 through April 30 each year. Establishments meeting size thresholds must also submit Form 300A electronically to OSHA.
Frequently Asked Questions
Who must keep an OSHA 300 Log?
Per 29 CFR 1904, employers with more than 10 employees in any year must keep OSHA 300 records, unless the employer is in a partially-exempt low-hazard industry listed in 1904.2 Appendix A. Construction, manufacturing, healthcare, transportation, and warehousing are not exempt. Employers under 10 employees average across all establishments are exempt from routine recordkeeping but must report serious incidents.
What injuries must be recorded?
Per 29 CFR 1904.7, work-related injuries and illnesses are recordable if they result in: death; days away from work; restricted work or transfer to another job; medical treatment beyond first aid; loss of consciousness; significant injury or illness diagnosed by a healthcare professional. First-aid-only cases are not recordable.
When must Form 300A be posted?
Per 29 CFR 1904.32, the prior calendar year's Form 300A summary must be posted in a conspicuous place where employee notices are customarily posted, from February 1 through April 30 of each year. The summary must be certified by a company executive.
Who must submit OSHA 300A electronically?
Per 29 CFR 1904.41, electronic submission to OSHA's Injury Tracking Application (ITA) is required by March 2 each year for: establishments with 250 or more employees in covered industries; establishments with 20-249 employees in designated higher-hazard industries (construction, manufacturing, healthcare, retail, transportation, warehousing). The 2024 final rule expanded submission for establishments with 100+ employees in 'highest-hazard' industries to also submit Form 300 and 301 data.
