It is late January, the job trailer whiteboard is full of punch-list items, and someone from the office asks a simple question: did we post last year's injury summary yet? For most construction contractors, OSHA 300 log recordkeeping fails exactly like this - not through a serious incident, but through three forms with three different deadlines that nobody owns end to end. The 300 log, the 301 incident report and the 300A annual summary each run on their own clock, and missing the February 1 posting is one of the easiest citations an OSHA inspector can write. This guide walks through what makes an injury recordable versus first aid, every deadline in order, the electronic submission rules, and how to keep determination errors from distorting the rates your insurers and prequalification systems read. If you would rather see how digital incident capture handles this than read about it, you can book a 30-minute walkthrough for your own crews and see the workflow live.
Three forms. Three deadlines. One February posting most crews forget.
The 300 log, 301 report and 300A summary are not one task - they are three separate obligations with different triggers, owners and clocks. Here is the whole system, in the order it actually bites you.
What sloppy injury recordkeeping actually costs a contractor
Recordkeeping citations are unglamorous, entirely preventable and surprisingly common. The numbers below are what is really at stake when the log goes stale.
Recordable injury vs first aid: the determination that drives everything downstream
Every recordkeeping problem starts with one question asked at the tailgate: is this OSHA-recordable, or is it first aid? Get it wrong once and the error compounds - your TRIR and DART rates shift, and those are the exact numbers insurers, owners and prequalification systems like ISNetworld and Avetta read when they score your company.
Usually recordable
- Any work-related injury causing days away from work, restricted duty or a job transfer
- Medical treatment beyond first aid - prescription medication, sutures, physical therapy
- Loss of consciousness, however brief, if it is work-related
- A diagnosed significant injury - fracture, cracked tooth, punctured eardrum - even without lost time
- Any work-related case meeting the general recording criteria under 1904.7
Usually first aid only
- Non-prescription medication at over-the-counter strength
- Wound cleaning, butterfly closures, Steri-Strips - never sutures
- Hot or cold therapy, elastic bandages, finger guards
- Tetanus immunizations and removing splinters by simple means
- Drinking fluids for heat stress, eye patches, massage as a comfort measure
The trap: the first-aid list in 1904.7(b)(5)(ii) is exhaustive. If a treatment is not on that list, it is medical treatment - and the case is recordable. "The medic just wrapped it" is not a determination. Someone with the list in front of them has to make the call, in writing, within 7 days.
OSHA recordkeeping deadlines in the order they hit you
Most citations happen because each form has a different trigger and a different owner. Lay them out on one timeline and the system stops being confusing.
Within 8 or 24 hours - severe event reporting
A fatality must be reported to OSHA within 8 hours of learning about it. An in-patient hospitalisation, amputation or loss of an eye gets 24 hours. These run on the shortest clocks in the whole rule and apply to every employer, even those otherwise exempt from keeping the log. Miss this window and you have a citation before the paperwork even starts.
Within 7 calendar days - 301 report and 300 log entry
Once you learn a recordable case occurred, you have 7 calendar days to complete the OSHA 301 incident report (or an equivalent workers' comp form) and enter the case on the 300 log. The 301 captures the detail: what the employee was doing, what happened, what the injury was, days away or restricted. The 300 log is the running register - one line per case, classified by outcome.
All year - keep the 300 log current
The 300 log is not a year-end chore. It must be updated within 7 days of any change - a case that was restricted duty becomes days away, a diagnosis changes, a count of lost days grows. Construction adds a wrinkle: you keep a log per establishment or per site expected to operate for a year or more, and short-term projects feed back to a central log. Crews move, foremen rotate, and cases fall through the cracks between sites.
February 1 to April 30 - post the 300A summary
At year end you total the log onto the 300A annual summary, a company executive certifies it with a signature, and it must be posted where employee notices are normally displayed from February 1 through April 30 - even if you had zero recordable cases. A blank year still requires a signed, posted summary. This is the deadline nobody owns, and the easiest citation an inspector can verify with one photo.
By March 2 - electronic submission through the ITA portal
Covered establishments - generally those with 20 or more employees in construction, plus any establishment OSHA has told to submit - must send their 300A data electronically through OSHA's Injury Tracking Application by March 2. Larger establishments in designated high-hazard industries, including construction at 100 or more employees, must also submit case-level 300 and 301 data. The portal does not remind you. If the person who did it last year left in November, March finds out.
One misclassified case distorts every number your clients read
Determination errors do not stay on the form. They flow straight into the rates that decide whether you get invited to bid.
A worked example on a mid-size crew
Say you run a 60-person site workforce logging roughly 120,000 hours a year. Three genuinely recordable cases puts your TRIR at 5.0 - already above the construction industry average, which typically sits in the 2.5 to 3.5 range. Now add two borderline cases your foreman logged "to be safe" - a wrapped wrist and an OTC-strength painkiller that were actually first aid. Your TRIR jumps to 8.3, and your EMR conversation with the insurer next renewal gets very uncomfortable. Prequalification systems flag anything above the client threshold automatically; nobody calls to ask whether two of those cases were really recordable. Over-recording hurts you exactly as much as under-recording, which is why the determination needs one trained owner, not five foremen guessing. If you want to see how a single determination workflow looks in practice, walk through it on a live demo with your own scenarios.

What OSHA expects vs what a defensible record looks like
An inspector, an owner's auditor or a plaintiff's attorney will all ask the same question: show me the record. This table maps each obligation to the evidence that actually closes it out.
| Obligation | Deadline | What a defensible record shows |
|---|---|---|
| Fatality / severe event report | 8 or 24 hours | Timestamped report with who was notified, when, and the initial incident description from the field |
| 301 incident report | 7 calendar days | Complete case detail - task, mechanism, body part, treatment - captured while memory is fresh, with photos |
| 300 log entry and updates | 7 days, ongoing | One line per case, classification column, running day counts, and an edit history when outcomes change |
| 300A certification and posting | Posted Feb 1 - Apr 30 | Executive signature, correct establishment totals, and proof of posting at each site |
| ITA electronic submission | March 2 | Confirmation receipt plus the exact dataset submitted, retained with the year's records |
| Retention and access | 5 years | Retrievable in hours, not days - employees and representatives have a right to copies on request |
Notice the pattern: every row depends on the quality of the first capture at the field level. If the incident detail arrives as a text message and a blurry photo three days later, everything downstream is reconstruction. Contractors who start capturing incidents digitally, free remove that gap at the source.
From field incident to audit-ready record, in one system
HVI is built for fleets and crews that work away from desks. Incidents, defects and corrective actions live in the same platform as your inspections and work orders, so nothing has to be re-typed into a spreadsheet at year end.
Field incident and defect capture
A supervisor logs the event on any phone at the site - photos, location, people involved, treatment given - while the facts are fresh. The 301 detail is 90% complete before anyone drives back to the trailer.
Role-based determination ownership
Safety staff own the recordable-versus-first-aid call with the criteria in front of them. Foremen report; they do not guess. One owner means one consistent standard across every site and every crew.
Incident-to-work-order linkage
Every case can spawn a corrective action - guard repaired, harness replaced, toolbox talk assigned - tracked to closure in the same work order system your shop already uses. Auditors love a closed loop.
Audit-ready retrieval in seconds
Timestamped, photo-backed records with full edit history, searchable by site, date, person or case type. When an inspector or a client's auditor asks, you pull the record on the spot instead of digging through five years of binders.
If your incident records currently live in group chats and a shared drive, see the same workflow on your own data in a demo before the next renewal or audit forces the issue.
OSHA 300 log recordkeeping, boiled down to what you do Monday morning
Name one determination owner. The recordable-versus-first-aid call is the judgement that drives every downstream number. Train one person per company or region, give them the 1904.7 first-aid list, and route every case through them within the 7-day window.
Put the five clocks on one calendar. 8/24-hour severe event reporting, 7-day 301 and log entry, continuous log updates, the February 1 to April 30 posting, and the March 2 ITA submission. Assign each a named owner and a reminder that survives staff turnover.
Treat your rates as bid documents. TRIR and DART feed insurers and prequalification systems directly. Over-recording hurts as much as under-recording, so accuracy - not caution - is the goal.
Capture at the field, not the trailer. Every obligation in the rule gets easier when the first record is made on a phone at the site, with photos, the same day. That is the entire case for moving OSHA recordkeeping for construction crews into a system like HVI - and you can sign up free and test it on one active site this week.
"The February posting used to sneak up on us every single year. I keep one number on my desk now: cases pending determination. If that is not zero by Friday, I know exactly who to call. We also stopped letting foremen decide what is recordable - one guy with the first-aid list makes that call, and our TRIR dropped a full point just from classifying honestly instead of cautiously."

OSHA recordkeeping questions contractors actually ask
What is the difference between the OSHA 300 log, the 301 report and the 300A summary?
The 300 log is your running register - one line per recordable case, kept current all year. The 301 is the detailed incident report for each individual case, due within 7 calendar days. The 300A is the annual summary of totals, certified by a company executive and posted February 1 through April 30. Three forms, three triggers, three deadlines.
How do I know if an injury is recordable or just first aid?
A work-related case is recordable if it involves death, days away from work, restricted duty, job transfer, medical treatment beyond first aid, loss of consciousness, or a significant diagnosed injury. The first-aid list in 1904.7(b)(5)(ii) is exhaustive - OTC medication, wound cleaning, Steri-Strips, hot/cold therapy and similar items. Anything not on that list counts as medical treatment.
Do small construction contractors have to keep an OSHA 300 log?
Employers with 10 or fewer employees at all times during the previous year are partially exempt from routine logkeeping - but every employer, regardless of size, must still report fatalities within 8 hours and hospitalisations, amputations or eye losses within 24 hours. Exempt employers must also keep records if OSHA or the BLS asks in writing.
Who has to submit injury data electronically through the ITA portal?
Establishments with 20 or more employees in designated industries - construction included - must submit 300A summary data electronically by March 2 each year. Establishments with 100 or more employees in high-hazard industries must also submit case-level 300 and 301 data. If you are unsure whether your sites qualify, book a demo and we will walk through your establishment structure and how digital records map to the submission fields.
How long do I have to keep OSHA injury records, and who can see them?
You must retain the 300 log, 301 reports and 300A summaries for five years following the end of the year they cover, and update the log during that period if case outcomes change. Current and former employees, their representatives and authorised employee representatives have the right to copies, generally by the end of the next business day. Digital storage with search makes this a minutes-long task instead of a box-digging exercise - sign up free and see how retrieval works.
