Free OSHA 300A Form Generator — The February 1 Posting, Handled

Your 300A summary, generated from your 300 log — printable, exportable, on time

What the 300A is

OSHA Form 300A is the Summary of Work-Related Injuries and Illnesses — the year-end totals from your 300 log: how many cases, how many days away or restricted, and the injury and illness types, plus your establishment’s average employment and total hours worked.

Unlike the 300 log itself, the 300A is the part your employees are supposed to see. That’s the whole point of the posting rule.

The dates that matter

• February 1 – April 30: the 300A covering the previous calendar year must be posted where you normally post employee notices, and stay up the entire three months.
• Before posting: a company executive must certify the summary by signing it — and OSHA defines that narrowly as one of four people: an owner, an officer of the corporation, the highest-ranking company official working at that establishment, or that official’s immediate supervisor. A safety coordinator’s signature alone doesn’t satisfy the rule unless they hold one of those roles.
• Zero injuries? You still post. A 300A full of zeros is a required posting, not an optional one.
• March 2: some establishments must also submit their data electronically through OSHA’s Injury Tracking Application. Whether you’re covered depends on establishment size and industry — check OSHA’s ITA page against your NAICS code.
• Five years: keep the 300 log, 300A summaries, and 301 forms on file and available.

Who has to do this

Most employers with more than 10 employees are covered by OSHA’s recordkeeping rule. Two groups are partially exempt from routine recordkeeping: companies that had 10 or fewer employees at all times during the previous year, and establishments in OSHA’s list of lower-hazard industries. (Everyone — exempt or not — still must report fatalities and severe injuries to OSHA directly.)

If you’re not sure which side of that line you’re on, the app’s recordability checker walks you through OSHA’s own criteria case by case.

How the free generator works

The 300A generator is one tab of our free OSHA recordkeeping app, so your summary comes from real entries instead of numbers typed from memory:

1. Log your incidents through the year (the app tells you what’s recordable and what isn’t).
2. Enter establishment info — average employees and total hours worked.
3. The 300A totals generate automatically, with validation warnings if something doesn’t add up.
4. Print it for the wall, or export the 300 log and 300A together to Excel.

Your log entries are saved in your own browser’s local storage — on your machine, not on our servers — and there’s no account to create. The payoff is that you build the log all year instead of rebuilding the year from a shoebox every January — just export to Excel as you go, because clearing your browser data clears the log with it.

While you’re at it: the same log powers a free TRIR calculator — the number every prequalification packet asks for.
