OSHA 300 log software records workplace injuries and illnesses and helps you produce the three required forms — the OSHA 300 (the running log of recordable incidents), the 300A (the annual summary that must be posted February 1 through April 30), and the 301 (the detailed incident report). It replaces error-prone spreadsheets and paper, enforces the 7-day logging deadline, and keeps your records audit-ready. For small businesses, the main benefit is never missing a recordkeeping deadline or failing an inspection over a paperwork gap.
Of all the ways a small business fails an OSHA inspection, recordkeeping is the most avoidable. Your injury numbers might be low and your crew might be safe — but if you can't produce a clean, current OSHA 300 log on demand, you can still be cited. Recordkeeping violations are pure paperwork failures, and they're 100% preventable.
This guide explains what the OSHA 300 log actually is, why spreadsheets and paper quietly set you up to fail, and what 300 log software does to keep you compliant year-round.
What is the OSHA 300 log?
The OSHA 300 log is the federal recordkeeping system for work-related injuries and illnesses. Most employers with more than 10 employees (outside of certain low-hazard industries) are required to maintain it. It's actually three connected forms:
| Form | What it is | Key deadline |
|---|---|---|
| OSHA 300 | The running log of every recordable injury and illness | Log within 7 calendar days of learning of the incident |
| OSHA 300A | The annual summary of the year's totals | Posted February 1 – April 30 each year |
| OSHA 301 | The detailed incident report for each case | Completed within 7 days of each incident |
The 300A must be posted in a visible workplace location even if you had zero recordable injuries that year — and all records must be retained for five years.
Why spreadsheets and paper fail an OSHA audit
Most small businesses track injuries in a spreadsheet or a paper binder. Both work fine — right up until an inspector asks for them. Here's where they break down:
- No deadline enforcement. Nothing reminds you of the 7-day logging rule or the February 1 posting date. Miss it and it's a citation.
- Easy to lose or fall behind. A binder gets misplaced; a spreadsheet stops getting updated mid-year.
- Manual summary math. The 300A totals are calculated by hand — and errors are common.
- Hard to produce on demand. When OSHA asks, "scattered across three people's emails" is not an acceptable answer.
What OSHA 300 log software does
Purpose-built recordkeeping software removes the manual work and the missed-deadline risk. At its core, it:
- Captures each recordable incident in a structured, consistent format
- Enforces the 7-day logging window so nothing slips
- Keeps the 300, 300A, and 301 data centralized and current
- Makes the annual 300A summary easy to produce and post on time
- Retains records for the required five years automatically
Spreadsheet vs. recordkeeping software

| Deadline reminders | 🔴 None | 🟢 Built in |
| 300A summary totals | 🟠 Manual math | 🟢 Calculated for you |
| Audit-ready in seconds | 🔴 Rarely | 🟢 Always |
| 5-year retention | 🟠 Manual | 🟢 Automatic |
| Single source of truth | 🔴 Scattered | 🟢 Centralized |
Frequently asked questions
Do small businesses have to keep an OSHA 300 log?
Most employers with more than 10 employees must, unless they're in a partially exempt low-hazard industry. Even exempt businesses must report severe incidents and may be asked to keep records by OSHA at any time.
What happens if I don't keep my 300 log current?
Recordkeeping failures are citable on their own, separate from any actual injury. Missing logs, a late 300A posting, or incomplete records can each result in penalties — which is why automating it is worth it.
Keep your injury records audit-ready year-round. Safety Team Technologies includes digital recordkeeping alongside automated training and hazard reporting — so your compliance records are centralized, current, and ready the moment OSHA asks. See how recordkeeping works or start your free trial.
