Three Lacerations and the Same Sentence
Over 14 months a fabrication shop has had three lacerations to the left hand or forearm, all at the same manual deburring station. Each investigation form reads: 'Employee failed to follow PPE policy. Corrective action: employee counseled and retrained on glove use.' The March case needed six sutures; the employee returned the same day on restricted duty for four days. The JSA for the station was last revised in 2016 and calls for leather work gloves. The glove bin by the parts washer holds only size L; three of the six employees assigned to the station need M or XL. Employees say the gloves soak up solvent and are uncomfortable, so they remove them to work faster. The supervisor says, 'We've retrained them every time and it keeps happening.' The March case has not been entered on the OSHA 300 log.
1. Critique the investigation and corrective action. What has been missed, and what should the investigation have produced instead?

The investigation stopped at the first convenient answer.
'Employee failed to follow policy' is a conclusion, not a cause. Three similar injuries at one station is a system signal, and the supervisor's own sentence - 'we've retrained them every time and it keeps happening' - is the argument against the corrective action, spoken aloud.
What the file never examined:
- PPE availability and fit. Six employees, one size on the shelf, three people who need a different size. A glove that is too large slips, and a glove that is too small comes off. PPE that does not fit the wearer is not PPE.
- Chemical compatibility. Leather work gloves plus a parts washer means solvent-soaked leather against the skin - degraded protection and a dermatitis driver, which is itself a reason people take them off.
- Task design. The hazard is contact with a sharp edge during a manual operation. The hierarchy asks whether the blade contact can be engineered out - a fixture to hold the part, a deburring tool with a guard, a file handle, repositioning the station away from the wash tank.
- The stale JSA. Last revised in 2016, it does not describe the process as it is run today, and it was evidently not written with the people doing the job.
- Production pressure. 'So we can work faster' is a rate and staffing observation that the investigation never followed.
What it should produce: corrective actions ranked by effectiveness, with an owner and a due date - engineering change first, then a glove selection and fitting process with at least two sizes stocked and a chemical-compatibility review, then a revised JSA developed with the operators, and only then training. Plus verification that each action held.
2. What must happen with the March case on the recordkeeping side, and who should make that call?
Read the worked answer
The case is recordable.
Six sutures is medical treatment beyond first aid. The first aid list covers wound coverings, butterfly bandages, and Steri-Strips; sutures are on the other side of the line. The case belongs on the OSHA 300 log and a 301 incident report within seven calendar days of learning about it.
How the columns work:
- He returned to work the same day, so there are no days away and no entry in the days-away column.
- He worked four days on restricted duty, which is entered as days of restricted work activity.
- The injury is not a privacy-concern case, so the name is entered.
The decision does not belong to the supervisor. He has a production incentive, he has already concluded 'first aid,' and he is the same person whose investigation produced the blame finding. Recordability should be decided by a person trained on the recording criteria, with the clinic's paperwork in hand, and reviewed monthly against the first aid log and the timekeeping system's restricted-duty records. The two earlier lacerations should be pulled and re-evaluated on the same basis - if either involved sutures or a prescription, they were missed too.
Two adjacent compliance points worth checking now: the plant's reporting procedure must not discourage or delay employees from reporting injuries, and had the outcome been an amputation or an in-patient hospitalization, the clock is 24 hours to OSHA - a decision this supervisor would have been making alone, at night, with no procedure.
3. How would you verify that the fix actually worked, given this history?
Read the worked answer
Define success before the fix is installed.
'No lacerations at the station for 12 months' is the lagging measure and it is necessary but not sufficient - with three events in 14 months, a quiet year could be luck. Pair it with measures that show the mechanism is different:
- Engineering adoption. Observe the station across several shifts and different operators: is the fixture or guarded tool in use, or is it set aside because it is slower? A control that gets bypassed is not a control.
- Fit and availability. Audit the glove bin monthly for size range and condition, and observe whether the correct size is actually worn.
- JSA currency and ownership. Confirm the JSA was rewritten with operator input and signed by the people who do the job, not issued from an office.
- Reporting behavior at the station. Near-miss reports from the deburring area should increase after the change. If they stay at zero, the reporting channel is still closed.
- First aid log. Small cuts that never reach the clinic are the earliest signal of recurrence; check the log, not just the 300.
- Supervisory response. Sample the next two investigations anywhere in the plant and check whether the conclusion is a system cause with a ranked corrective action, or a name. That tells you whether the change is local or cultural.
Close the loop with the three injured employees: tell them what was changed and why. That single act does more for reporting than any poster.
