What the Rule Requires
OSHA's medical services and first aid standard, 29 CFR 1910.151, requires employers to ensure medical personnel are available for advice, and to have trained first aid providers and supplies when a medical facility is not close. Remote oilfield locations qualify: the response has to be designed, not assumed.
The Kit and the Trained Hands
First aid supplies should match the work: cuts and burns from maintenance, eye exposure from chemicals, heat illness, and crush injuries. OSHA's guidance on medical and first aid services describes assessing hazards and stocking accordingly, with training refreshed so the hands that use the kit are current.
The Minutes That Matter
In cardiac arrest, defibrillation in the first minutes is the difference. AED programs put the unit on location and train crews to use it. The plan answers three questions in advance: who responds, what is on site, and how the injured worker reaches help, by ambulance, helicopter, or escort.
The record that closes the loop
First Aid and AEDs on Location rests on the same field data as the rest of the operation: tickets, timesheets, approvals, and inspections. The same discipline shows up in Incident investigation and TRIR and Near miss reporting and H2S monitoring at the wellsite. If those records live in notebooks, email, and memory, start with an operations audit.
