How to Complete Your OSHA Required – 300 Log Posting

It’s that time of the year! OSHA requires that employers post the summary of their OSHA 300 log from 02/01 until 04/30 of the previous year.   And while OSHA provides a very detailed instruction pamphlet (, it is a bit exhausting.

We have taken the OSHA provided excel spreadsheet and color-coded the areas that you need to input. A couple of quick helpful hints and notes about the log itself:

  1. A) OSHA Form 300 = This is the details you enter for each claim. You do NOT post this. The excel spreadsheet tallies this information on the next tab, the OSHA Form 300 A.
  2. B) OSHA Form 301 (the 3rd tab) is an accident investigation form. You are not required to use OSHA’s form, but may do so. It does not directly pertain to the required posting of the summary, but OSHA protected this document when they publish it so you can see it.
  3. C) We have included a sample injured worker to demonstrate how the form works, named “John Doe.” You can click on the second tab, OSHA Form 300A, and view that the sheet tallies the information from the first tab.

Here is a quick summary of what to do:


STEP 1 = Enter your company information on rows 11 & 12.

STEP 2 = Enter the information for each injured worker beginning in row 25 (delete John Doe and replace with your real worker(s)’ name). Enter the information for columns A through F for each worker. A case number is not required so we did not highlight that field. If you have an internal control number or a work comp claim number, you can enter it there.

STEP 3 = Columns G-J – Indicate the ONE description that applies with an “x.”

STEP 4 = Columns K-L – IF the employee had days away from work or restrictions, then enter the number that applies here.

STEP 5 = Columns M-R (1-6) – Indicate the type of injury or illness with an “x.”

STEP 6 = Repeat for each employee.


STEP 1 = Enter your company information in columns P-AJ. The SIC/NAICS is optional. AccuSure users are able to easily look up their SIC when they create a Request For Insurance with a simple keyword search. ALSO – many employers do not track the specific hours worked. Do your best to be accurate with this number, but many employers estimate based on number of employees and average workshift hours.

STEP 2 = Print this summary page ONLY. Do NOT print the page that includes employee information (the first tab).

STEP 3 = Post this summary from 02/01 – 04/30 along with your other employee postings (typically near the timeclock or where you place other state required employer postings).
