29 CFR 1904 recordkeeping
300log keeps the OSHA 300 Log, 301 incident reports and 300A annual summary for every establishment in one workspace, then gets them to OSHA's Injury Tracking Application (ITA) as a CSV you upload, or files them for you through OSHA's API as soon as you authorize.

The filing calendar
Every fixed OSHA recordkeeping date sits on the same twelve-month cycle. See where today falls, what's due next, and put every deadline on your calendar in one step. On a paid plan, 300log also emails you when to post the 300A (by February 1), before the March 2 ITA deadline if you haven't filed yet, and when it can come down after April 30.

Rolling clocks
The dial holds the fixed dates. These windows start when something happens: an injury, a severe event, or a records request.
How it works
An incident happens on the shop floor. Months later it has to add up on a certified summary and reach OSHA. 300log carries the case the whole way.
Recordability, worked through
Stitches or a butterfly bandage. A parking-lot fender bender or a needlestick. Pick a case and watch the same rules the workspace uses decide whether it goes on the OSHA 300 log, and in which column.

Full rate calculatorAutomatic ITA filing
Connect the API token from your OSHA Injury Tracking Application account and authorize the certified 300A. 300log submits it right away, retrying automatically whenever OSHA's system is down.
Due March 2 · 29 CFR 1904.41
You create the API token in your own OSHA ITA account, signed in with Login.gov, and paste it once. It is verified with OSHA, stored encrypted, and only the last four characters are ever shown. Remove it any time.
Authorizing runs the same checks as the PDF packet and locks a snapshot of the 300A. Only that snapshot is sent. If the records behind it change afterwards, the workspace flags it so you can authorize again.
300log submits it right after you authorize (before January 2, as soon as the ITA opens) and tries again automatically when the ITA is unavailable. When OSHA accepts it, you see OSHA's submission ID and get it by email; OSHA also emails its own confirmation to your ITA account.
Prefer to upload it yourself? The ITA-format CSV export stays one click away in Files, whether or not auto-filing is on.
Industries · 29 CFR 1904
Part 1904 reads the same on a scaffold and on a ward. The hard calls don’t. Here are a few your team will meet, and what the rule says about each.
A subcontractor’s laborer is hurt on your site.
Whoever supervises the work day to day records the case, and only one of you should.
§ 1904.31(b)(3)The job wraps up in six months.
Sites expected to run for less than a year can share one 300 log instead of keeping one each.
§ 1904.30(b)(1)
An annual audiogram shows a standard threshold shift.
Record it if the shift averages 10 dB or more and hearing is 25 dB or more in that ear, unless a retest within 30 days doesn’t confirm it.
§ 1904.10A metal sliver lands in an operator’s eye.
Flushed out or lifted with a cotton swab, it’s first aid. Removed any other way, it’s medical treatment and recordable.
§ 1904.7(b)(5)
A forklift operator strains a shoulder and goes on light duty.
If they can’t do the routine functions of their job, it’s a column I case. Count the restricted days in column L.
§ 1904.7(b)(4)A temp from a staffing agency is hurt on your dock.
If your supervisors direct their work day to day, the case goes on your log, not the agency’s.
§ 1904.31(b)(2)
The ledger
Each entry is something the workspace does today. The chip on the right is the rule it answers to, linked to the text on osha.gov.
Phone & desktop
The person who sees the injury is rarely at a desk. 300log works on the phone in their pocket, with controls that feel native, not a desktop page squeezed small.
Install it once and it launches full-screen from the home screen or dock, right into the workspace. No bookmarks, no browser bars.
On phones, bottom sheets, a tab bar and a one-tap New incident button replace desktop menus, with tap targets of at least 44 px.
Your records are saved to your account, so a case logged on the floor from a phone is on the office computer too. Sign in (Google or email) on each device; it needs a connection to load and save.

Hear from the people keeping their OSHA records in order with 300log.
I used to dread late-shift incidents because it meant updating the 301 and then manually typing the exact same information into the 300 log. That’s always where the typos happen. With 300log.com, you enter the intake details once and both forms are tied together and done. Huge time saver and way less room for human error.
Mark T.
Warehouse Safety Manager
Managing OSHA logs for seven different manufacturing plants used to be a nightmare of emailed spreadsheets and version control issues. Now, each site has their own log, but I can log in and see every open case or upcoming deadline across the whole company from one screen. Easiest software rollout we’ve had.
Sarah J.
Regional EHS Director
The 300A summary used to take me a full day of triple-checking my days-away counts and making sure my spreadsheet formulas didn't break. This year it took about five minutes. Because the totals pull straight from the active log, there’s no more hunting through rows trying to find a missing day. The math just works.
David R.
HR & Compliance Coordinator
If you’ve ever spent February fighting with a CSV file trying to get the formatting right for the ITA upload, just get this software. 300log spits out the exact file OSHA wants for the electronic submission. Missing fields get flagged before you export, so there are no surprises when the March deadline hits.
Elena M.
Safety Compliance Officer
I’m not a tech guy, I just want my compliance stuff done so I can get back on the floor. I was worried this would be bloated, but it’s actually straightforward. It tracks exactly what OSHA requires without a bunch of useless extra features. Support team is quick to reply, too.
Tom K.
Operations Lead
We were doing everything on Excel for years. Moving to 300log.com was surprisingly painless. Being able to just hit export and have a clean, compliant record ready for an inspector gives me a lot of peace of mind.

FAQ
The questions safety and HR teams ask first. Each answer points to the section of 29 CFR 1904 it comes from.
The 300 is the log: one line for every recordable work-related injury and illness in the calendar year. The 301 is the incident report behind each line, with the details of what happened. Both must be filled in within 7 calendar days of learning about a recordable case. The 300A is the year-end summary of the log (column totals, average employees and hours worked), certified by a company executive.
Establishments that had 20–249 employees at any point last year and are in an industry listed in Appendix A to Subpart E submit their 300A. Establishments with 250 or more employees that must keep records also submit the 300A. Establishments with 100 or more employees in an Appendix B industry submit their 300 and 301 case data as well. Everything goes through OSHA’s Injury Tracking Application (ITA) by March 2 for the previous year, and the headcount includes part-time, seasonal and temporary workers.
Post the certified 300A from February 1 to April 30, in a conspicuous place where you usually post notices to employees. Post it even if you had no recordable cases; the column totals are simply zeros.
Report a work-related fatality within 8 hours, if the death occurs within 30 days of the incident. Report an in-patient hospitalization, amputation or loss of an eye within 24 hours, if it occurs within 24 hours of the incident. Call 1-800-321-6742, contact your Area Office, or report online. This applies even to employers that are exempt from keeping injury logs.
Keep the 300 log, the 300A and the 301 reports for five years following the end of the calendar year they cover, and update the 300 logs during that time if you learn of new cases or changes. Records for 2026, for example, are kept through 2031.
Your establishments, 300 log, 301 reports and 300A details are kept securely in your 300log account. Only you and the people you invite can open them, and they're there on any device you sign in on. Nothing is sent to OSHA until you authorize a filing, and you can disconnect your ITA token at any time.
Yes. On phones the workspace uses bottom sheets, a tab bar and large tap targets. Install it from Safari (Share, then Add to Home Screen) or from Chrome or Edge (Install app) and it opens full-screen, straight to your log. It needs a connection to load and save your records, since they are stored in your account.
No. 300log is independent recordkeeping software. It isn’t affiliated with or endorsed by OSHA or the U.S. Department of Labor. It organizes your records and filings, but recordkeeping decisions remain the employer’s responsibility.

Year-end · 29 CFR 1904.32
Review the log, total the columns, have an executive certify the summary and post it by February 1. If your establishment is covered, the 300A is due in OSHA's ITA by March 2. 300log keeps every step in one place.
