Incidents
OSHA 300 Log
OSHA-mandated log of work-related injuries and illnesses.
US employers with 11+ employees must maintain the OSHA 300 Log throughout the year. Each entry records: case number, employee name, job title, date, injury/illness type, and outcome (days away, restricted duty, etc.). The companion Form 301 captures per-incident details. The 300A summary is posted 1 Feb – 30 Apr each year.
