If you run a business, you’ve probably heard about the OSHA 300 Log. It sounds complicated, but it’s really just a simple record book. Let’s break it down so anyone can understand it.
What is the OSHA 300 Log?
The OSHA 300 Log is a form where you write down work-related injuries and illnesses. Think of it like a diary that tracks when workers get hurt or sick because of their job.
The official name is “Log of Work-Related Injuries and Illnesses.” But everyone just calls it the 300 Log.
Who Needs to Keep This Log?
Most businesses with more than 10 employees need to keep this log. However, there are some exceptions:
You DON’T need it if:
- You have 10 or fewer employees
- You’re in a low-risk industry (like retail stores or offices)
You DO need it if:
- You have 11 or more employees
- You’re in construction, manufacturing, or other higher-risk work
- OSHA specifically requires your industry to keep it
When in doubt, keep the log. It’s better to have it than to get fined for not having it.
What Goes on the 300 Log?
You record injuries and illnesses that are:
Work-Related: It happened because of the job or at the workplace.
Serious Enough: The injury or illness required medical treatment beyond basic first aid, caused days away from work, or resulted in job restrictions.
What You DO Record
- Cuts that need stitches
- Broken bones
- Sprains that need more than ice and bandages
- Burns that need medical care
- Hearing loss from workplace noise
- Illnesses from chemical exposure
- Back injuries that limit work duties
- Any injury causing missed workdays
What You DON’T Record
- Small cuts treated with bandages
- Minor burns
- Splinters removed with tweezers
- First aid, like ice packs or pain relievers
- Common colds or flu
- Injuries from the employee’s commute (driving to work)
The Three Forms You Need to Know
OSHA actually uses three forms that work together:
Form 300: The Log
This is the main record. It lists every recordable injury or illness throughout the year. Each incident gets one line with basic details.
Form 300A: The Summary
At the end of the year, you count up all the injuries and fill out this summary sheet. You post this in your workplace from February 1 to April 30 so workers can see it.
Form 301: The Incident Report
For each injury on the 300 Log, you fill out a detailed incident report. This form has more information about what happened, how it happened, and what treatment the worker received.
How to Fill Out the 300 Log
The form has columns for:
Case Number: Just number them in order (1, 2, 3, etc.)
Employee Name: The worker who got hurt or sick
Job Title: What their position is
Date of Injury: When it happened
Where It Happened: Location in your facility
What Happened: Brief description of the incident
Type of Injury: Was it an injury or illness?
Days Away/Restricted: Did they miss work or have limited duties?
Classification: Check the box for death, days away, job transfer, or other
Step-by-Step: Recording an Injury
Let’s say a worker cuts their hand and needs stitches:
- Get the details: What happened? When? Where?
- Determine if it’s recordable (stitches = yes)
- Fill out Form 301 (the detailed incident report)
- Add a line to Form 300 (the log)
- Keep both forms in your records
- Update your totals at year-end
When to Record It
You have seven days from when you learn about the injury or illness to record it. Don’t wait until the end of the year. Do it as soon as you know about it.
The Annual Summary (Form 300A)
Every year between January and early February:
- Count all injuries and illnesses from the 300 Log
- Fill out Form 300A with these totals
- Have a company executive sign it
- Post it where workers can see it (February 1 – April 30)
- Keep it on file for five years
Privacy Protection
Some injuries are sensitive. For privacy concerns like
- Mental illnesses
- HIV/AIDS
- Hepatitis
- Certain reproductive health issues
- Needlestick injuries with bloodborne pathogens
You can leave the employee’s name off the 300 Log. Use “Privacy Case” instead. But you still need to keep Form 301 with the name in a confidential file.
Common Mistakes to Avoid
Mistake 1: Not recording injuries because you think they’re too minor. When in doubt, record it.
Mistake 2: Forgetting to post the summary. You must display it every year from February 1 to April 30.
Mistake 3: Throwing away old logs. Keep them for five years, even if no one got hurt that year.
Mistake 4: Not updating the log promptly. You have seven days, not seven months.
Mistake 5: Missing the signature on Form 300A. A company executive must sign it.
Electronic Records
You can keep these forms on a computer instead of on paper. Just make sure you can:
- Print them if needed
- Protect them from being changed
- Access them quickly during an OSHA inspection
What Happens During an OSHA Visit?
Inspectors will ask to see your 300 log. They check if:
- You’re recording injuries properly
- Your summary is posted on time
- The information is accurate
- You’ve kept records for five years
If your log is missing or incomplete, you can get fined.
Tips for Keeping Good Records
Create a System: Decide who records injuries and when. Make it someone’s specific job.
Train Your Team: Managers should know what to record and how.
Report Quickly: Tell workers to report injuries right away, even small ones.
Review Monthly: Check your log once a month to catch any mistakes.
Keep Everything: Save all three forms (300, 300A, and 301) together.
Be Honest: Never hide injuries to make your numbers look better. That’s illegal and dangerous.
Why This Matters
The 300 Log isn’t just paperwork. It helps you:
Spot Patterns: If lots of workers hurt their backs, maybe you need better lifting equipment.
Improve Safety: When you track injuries, you can prevent future ones.
Stay Legal: You avoid fines and penalties.
Protect Workers: You create a record if someone needs workers’ compensation.
Show You Care: Good record-keeping shows you take safety seriously.
The Bottom Line
The OSHA 300 Log is simpler than it seems. It’s just a list of work injuries and illnesses. Keep it updated, post your summary each year, and store everything for five years.
Think of it as taking care of your workers. When someone gets hurt, you write it down, figure out what went wrong, and try to stop it from happening again. That’s what good businesses do.
If you’re still confused, OSHA has free guides and even offers help. Don’t be afraid to ask questions. It’s better to get it right than to guess and get it wrong.
