OSHA Form 300: Log of Work-Related Injuries and Illnesses is a record of all observable incidents that happened in the past calendar year, including details regarding employee information and description of the injury or illness. OSHA Form 300A provides a summary of this data, and OSHA Form 301 provides additional context for individual cases.
When are OSHA 300 forms due?
OSHA Form 300, 300a and 301 must be submitted to OSHA before March 2nd of each calendar year. If your organization misses the deadline, you are still required to submit your data.

Organizations typically must submit Form 300A if they:
- Have 250 or more employees, unless they are in an exempt industry
