First Aid, CPR and AEDs on the Location: The Medical Response Baseline

On an oilfield location the nearest hospital is often an hour or more away, and the clinic may not exist at all. When a worker is injured or collapses, the first minutes decide the outcome, so first aid, CPR and AED readiness matter on every location. This guide covers what OSHA requires under 29 CFR 1910.151 and how a practical first aid program runs on a remote site.

What 29 CFR 1910.151 requires

OSHA's medical services and first aid standard, 29 CFR 1910.151, sets the baseline for employer responsibility on every covered workplace, oilfield locations included. It carries two main requirements.

• If no infirmary, clinic or hospital is in near proximity to the workplace, the employer must have a person or persons adequately trained to render first aid. On a remote location, that means a trained responder on hand for every shift.
• Where employees are exposed to corrosive materials, the employer must provide suitable facilities for quick drenching or flushing of the eyes and body. In practice this means emergency eyewash and shower equipment wherever corrosives are handled, such as near acid tanks, chemical storage and well treatment units.

The standard does not list kit contents or prescribe a training course. It sets the outcome: a trained person must be available to give first aid when no clinic or hospital is close, and corrosive exposures must be washable on the spot.

What near proximity means on a remote location

OSHA interprets near proximity in terms of response time, and its first aid guidance treats about four minutes as the benchmark for care to reach a seriously injured worker. On a lease road or pad there is no facility inside that window, so the trained responder and the stocked kit are the practical answer. Response time is the whole point: every minute the clinic is away, the crew has to cover it.

Coverage has to exist every shift and every phase of the job, not just daylight hours with a full crew. When a rig crew, a wireline crew and a frac spread share a location, each crew needs to know who its responder is, because nobody should guess in the moment.

CPR and AED programs

OSHA does not set a blanket CPR certification requirement in 1910.151; its training requirement is first aid, and CPR policy is left largely to the employer. OSHA has also published guidance strongly encouraging CPR and AED programs, and many operator contracts require current CPR certification regardless of the federal minimum.

An AED program is more than buying a device. A working program covers placement, training, maintenance and coordination with emergency services.

• Placement: the AED must reach an incident fast, which on a spread-out pad often means more than one unit or one on a service truck that moves with the crews.
• Training: responders need hands-on practice with CPR and the device, with refreshers on a schedule. Skills fade faster than certificates.
• Maintenance: the unit, the batteries and the electrode pads need checks on a schedule, and pads carry expiry dates that get missed when nobody owns the list.
• Coordination: emergency services need the lease location, the access route and the site layout, and the crew needs to know what happens between the call and the ambulance.

An AED talks a trained responder through every step, but a device nobody can find, or one with dead batteries, is a false sense of security.

First aid supplies: the ANSI/ISEA Z308.1 reference

The regulation does not spell out a kit contents list, and industry practice fills the gap. Most employers follow the minimum requirements of ANSI/ISEA Z308.1, the consensus standard for workplace first aid kits and supplies. It is an industry reference, not a law, but it is the benchmark kit suppliers build to and many operator contracts point to.

The standard sizes a kit to the people it serves and classes it by contents and environment. A field location, where crews deal with cuts, burns, sprains and eye exposures, needs more than a basic cabinet, and the kit only works if it is maintained.

• Restock after every use, and do it before the next shift, not when the box is opened in an emergency.
• Check expiry dates on a schedule. Burn dressings, antiseptics and some bandages all have shelf lives.
• Keep the kit where the crew can reach it and everyone knows where it is, and consider a kit per crew truck on a multi-crew location.

Field planning around the nearest care

First aid on location is the first link, not the last. The plan has to answer what happens after the responder acts, and that planning happens before the injury, not during it.

• Know the nearest trauma center and the air or ground evacuation route, and verify the route ahead of time. A road closure or a locked gate changes the plan.
• Keep the emergency contact list posted: emergency services, the operator's HSE contact, the nearest clinic and hospital, and the medevac number if available.
• Assign trained responders per crew and per shift, name a backup, and make the assignments visible in the daily plan.
• Practice the drill. Response speed comes from rehearsal, and a practiced crew finds the kit, clears the area and starts care in seconds.

The same discipline behind H2S contingency planning and HAZWOPER emergency response applies here: know the hazard, name who acts, and rehearse the response before the emergency arrives.

Training records and keeping the program current

First aid readiness is not a one-time checkbox. Responders need training at hire and refreshers on a schedule, and the employer should keep a record of who is certified and when each certification expires. Where crews rotate and contractors come and go, that record proves coverage shift by shift and job by job.

Logging first aid training and certification expiry dates for crews keeps the program honest, and software like OpsFlo carries that record: it handles field tickets, dispatch, approvals, timesheets and documents, so the training record travels with the crew instead of living in a filing cabinet nobody opens.

Review the program on a schedule. When the crew changes, the location moves, or an incident happens, ask whether the responder list, the kit contents, the AED checks and the evacuation route are still true. The first aid program is only as good as the last drill, the last restock and the last certification renewal.
