OSHA 300 log: add a case, see if it counts.
Answer what happened. See if it goes on the log, which column, and the days to count.
- Case 1 · Employee name and job title · Cut hand on rebar, 4 stitches at urgent care
- Record it within 7 calendar days of learning about it (1904.29(b)(3)).
- Fill a 301 incident report (or your workers' comp form) for the same case.
- It counts in your 300A totals at year end.
Free, no sign-up. A starting point: check it against the rule cited.
The columns
G: death. H: days away from work. I: job transfer or restriction. J: other recordable cases. Check only the most serious one. K and L count the days away and the days restricted, capped at 180 each.
Privacy cases (an injury to an intimate body part, sexual assault, mental illness, HIV, hepatitis or TB, a contaminated needlestick, or when the worker asks) go on the log without the name: write "privacy case" instead.
From the log to the 300A
At year end you total the columns on the 300A, have a company officer certify it, and post it from February 1 to April 30. Dozer carries every case into the 300A totals so the summary fills itself.
A starting point, not legal or safety advice. Check it against the regulation cited and your own site.
Keep the log all year. The 300A fills itself.
Log an injury on the phone the day it happens. Dozer keeps the OSHA 300 log, the 301 forms and the hours, then fills the 300A in January.
- Injuries logged the same day, from the phone
- 300, 301 and 300A kept together
- TRIR and DART all year, not just in January
- A reminder to post Feb 1 and file by Mar 2

Questions crews ask
What makes an injury recordable on the OSHA 300 log?
A work-related new case that leads to death, days away from work, restricted work or a job transfer, medical treatment beyond first aid, loss of consciousness, or a significant injury or illness a doctor diagnoses (29 CFR 1904.7).
What counts as first aid?
The list in 1904.7(b)(5)(ii): non-prescription medicine at normal strength, tetanus shots, cleaning and bandaging wounds, butterfly strips, hot or cold packs, splints for transport, removing splinters, eye patches, finger guards, massages and drinking fluids. Stitches, prescriptions and rigid splints are medical treatment.
How long do I have to record a case?
Seven calendar days from when you learn about it (1904.29(b)(3)).
Who has to keep an OSHA 300 log?
Employers with more than 10 employees at any time in the last year, unless their industry is partially exempt. Most construction (NAICS 23) is not exempt.
