Amputation at the Press Brake: Whose Clock Is Running?
At 2:40 p.m. on a Tuesday, a 22-year-old temporary worker placed through a staffing agency had the tip of his right index finger amputated by the point of operation on a mechanical press brake. The press brake's light curtain had been bypassed six weeks earlier because it 'false tripped.' The worker was driven by a coworker to an urgent care clinic, which transferred him to a hospital where he was admitted overnight for surgery. The shift supervisor called the plant's safety hotline the next morning and told the staffing agency the same day. The OSHA 300 log has not been updated. On Thursday the plant manager asks whether anything needs to be sent to OSHA, and whether the case is recordable at all since the worker is 'not our employee.'
1. What reporting obligations exist, what were the deadlines, and where does the company stand now?
Read the worked answer
Two reporting clocks started at 2:40 p.m. Tuesday and both expired at 2:40 p.m. Wednesday. Under 29 CFR 1904.39, an amputation must be reported to OSHA within 24 hours of the employer learning of it, and an in-patient hospitalization for treatment must also be reported within 24 hours. The amputation is reportable even if the worker had not been hospitalized. Calling the internal hotline and notifying the staffing agency do not satisfy the rule; the employer must contact OSHA directly, by telephone to the area office or through the online reporting form.
By Thursday the report is late. Call the area office immediately, report the event, and explain the delay rather than waiting further. Then fix the intake: a designated 24/7 contact with authority to report, a written decision tree distinguishing the 8-hour fatality clock from the 24-hour clock, and a rule that the supervisor's first call is to that contact.
Recordability: the host employer records the case. Under 1904.31, the employer that supervises the worker day to day records the injury; temporary status does not transfer that duty, and the staffing agency may also have to record it on its own log.
2. Is the case recordable, how should it be classified, and what entries and timelines apply?
Read the worked answer
Yes, it is recordable. Amputation of a fingertip requiring surgical repair is medical treatment beyond first aid under 1904.7(b)(5); the first-aid list covers things like compresses, bandages, and non-prescription medication, not surgery. Classify it based on the outcome: days away from work if the worker is off, or restricted duty or job transfer if he is placed on light duty. Enter it on the 300 log within seven calendar days of learning of the case (1904.29(b)(3)), recording the date, the body part, and the case classification.
Do not treat the injury as a privacy case automatically; only the specific privacy-concern cases listed in 1904.29(b)(6) permit withholding the name. Confirm the number of days away and update the entry when the count is known. Separately, check whether the establishment is in a covered industry for electronic submission under 1904.41 and whether a submission window applies. Record the case yourself; do not wait for the staffing agency to record first.
3. Design the investigation and the corrective actions. What would you look at first, and what fixes would you require?
Read the worked answer
Focus on root causes, not blame. The decisive fact is that the light curtain was bypassed for six weeks, which is a management-of-change and safeguarding failure, not a rogue operator. Reconstruct the sequence: who authorized the bypass, what work order existed, whether a risk assessment covered operating without the device, what compensating measures were put in place, and who verified the guard before the press returned to production. Include production pressure and staffing in the analysis, because those are common contributing causes.
Run the investigation with a small team including the operator, maintenance, and a staffing-agency representative; interview witnesses separately, photograph and preserve the scene, and pull maintenance records and camera footage.
Corrective actions: redesign the circuit so a bypass requires a keyed, time-limited permit with compensating controls; add a guard-verification check at every shift change; deliver documented task-specific training to temporary workers before assignment; audit the whole plant for disabled or removed guards; and strengthen near-miss reporting so a bypass surfaces in days rather than weeks. Assign an owner and due date to each action and track closure to completion.
