What is OSHA Form 300?

OSHA Form 300 is the Log of Work-Related Injuries and Illnesses. Covered employers enter each recordable case within 7 calendar days, post the yearly summary from February 1 to April 30, and keep the records for 5 years.

In shortOSHA Form 300, the Log of Work-Related Injuries and Illnesses, is the running list a covered employer keeps of recordable injuries and illnesses at each establishment. Each line shows the employee, the job, the date and where the event happened, a short description, and how serious the case was, such as days away from work, restricted work or job transfer, or other recordable cases. A recordable case is generally a work-related injury or illness that results in death, days away from work, restricted work or transfer, medical treatment beyond first aid, loss of consciousness, or a significant diagnosed injury or illness. Under 29 CFR 1904.29, the employer must enter a case on the 300 Log and complete a Form 301 incident report, or an equivalent, within 7 calendar days of learning about it. After the year ends, the employer totals the log on Form 300A and posts the summary from February 1 to April 30. The log, the summary and the 301 reports must be kept for 5 years. Employers with 10 or fewer employees at all times during the last calendar year, counted company wide, are partially exempt from keeping these records, but every employer must still report a fatality within 8 hours and an in-patient hospitalization, amputation or loss of an eye within 24 hours.

Worked example: is this cut recordable?

Stitches on a Tuesday

A warehouse with 85 employees has a picker cut his hand on a box cutter on Tuesday, March 9. The shift lead cleans it and applies a bandage, and the picker goes to urgent care, where he gets four stitches. He comes back the next day to his normal job.

Cleaning and a bandage are first aid, but stitches are medical treatment beyond first aid, so the case is recordable even though he lost no work time. The safety coordinator has 7 calendar days, so she enters it on the 300 Log as an other recordable case and completes the Form 301 by Tuesday, March 16.

If he had been put on light duty for a week, the case would go in the restricted work or transfer column instead. At year end, this case is part of the totals on the Form 300A that is posted in the break room from February 1 to April 30.

Mistakes that are specific to the 300 Log

Privacy cases and employee access

For certain cases, the employer must not enter the employee’s name on the 300 Log. Instead it writes privacy case in the name column and keeps a separate confidential list of the case numbers and names. These privacy concern cases include an injury to an intimate body part or the reproductive system, an injury from a sexual assault, mental illnesses, HIV infection, hepatitis or tuberculosis, needlestick and sharps injuries from contaminated objects, and other illnesses when the employee asks for their name to be withheld.

Employees, former employees and their representatives can ask for a copy of the log for their establishment, and the employer must provide it by the end of the next business day.

Second example: counting restricted days

A stocker strains his shoulder and is put on restricted work, no lifting above shoulder height, for 25 calendar days. He comes to work every day.

The case is recorded in the restricted work or transfer column, and the log counts the calendar days of restriction, not only the scheduled workdays. The count stops at 180 days if a case goes on that long. The safety coordinator updates the day count when the restriction ends.

Set the 7-day clock when the report comes inHave every incident report open a task with a due date 7 days out. The 300 entry and the 301 then get done while the facts are fresh, instead of being rebuilt from memory in January.
