OSHA’s CPR and first aid training requirements turn on one question: can emergency medical services reach an injured worker fast enough? Under 29 CFR 1910.151(b), general industry employers must have trained first aid providers on site whenever no infirmary, clinic, or hospital is in “near proximity” to treat injured employees.1eCFR. 29 CFR 1910.151 – Medical Services and First Aid Several industry-specific standards go further and require trained personnel no matter how close the nearest hospital sits.
What “Near Proximity” Actually Means
The regulation doesn’t define near proximity in miles. OSHA has clarified through interpretation letters that it’s measured by response time. Where life-threatening injuries are foreseeable (severe bleeding, cardiac arrest, electrocution), emergency care must be reachable within three to four minutes.2Occupational Safety and Health Administration. Clarification of In Near Proximity and OSHA Discretion in Enforcing 29 CFR 1910.151(b) For lower-risk environments like typical office buildings, OSHA has historically allowed up to about 15 minutes before on-site trained personnel become mandatory.
So a warehouse with heavy machinery and a law office five floors above it in the same building can face very different obligations under the same regulation. If the nearest ambulance can’t make the applicable window, you need trained first aid providers on every shift.
The regulation says “a person or persons” without setting a number. In practice, you need enough trained employees on duty at all times that someone is always available. If your only trained responder calls in sick, you have a compliance gap. Most safety professionals train at least two people per shift to cover absences and vacation.
Industries Where Training Is Required Regardless of Distance
Several OSHA standards impose stricter rules that apply whether or not a hospital is nearby.
Construction
Under 29 CFR 1926.50(c), construction employers must have a person with a valid first aid certificate on site whenever no physician or medical facility is “reasonably accessible in terms of time and distance.” The construction standard is more prescriptive about credentials than general industry: the certificate must come from the U.S. Bureau of Mines, the American Red Cross, or an equivalent program verifiable by documentation.3Occupational Safety and Health Administration. 1926.50 – Medical Services and First Aid Because sites move, this assessment has to happen at every new jobsite.
Logging
Under 29 CFR 1910.266(i)(7), every employee at a logging operation, including supervisors, must receive first aid and CPR training meeting the standard’s Appendix B requirements.4Occupational Safety and Health Administration. 1910.266 – Logging Operations Not “someone available.” Everyone. First aid kits are also required at each cutting site, each active landing, and in every crew transport vehicle.
Electric Power Generation, Transmission, and Distribution
For work on or near exposed lines or equipment energized at 50 volts or more, 29 CFR 1910.269 requires trained first aid and CPR providers to be available. At field locations with two or more employees, at least two must be trained. At fixed locations like generating stations, the employer must have enough trained people that any employee suffering an electric shock can be reached by a trained responder within four minutes.5eCFR. 29 CFR 1910.269 – Electric Power Generation, Transmission, and Distribution
Telecommunications
Under 29 CFR 1910.268, telecommunications employers must provide first aid training that includes artificial respiration. When employees work in manholes with traffic exposure, water hazards, or shared occupancy with power utilities, a person with basic first aid training must be immediately available in the vicinity.6Occupational Safety and Health Administration. 1910.268 – Telecommunications
What the Training Has to Cover
Training must go beyond a lecture. Employees need to demonstrate they can perform the skills, not just describe them. OSHA’s Best Practices Guide outlines the core topics:7Occupational Safety and Health Administration. Best Practices Guide – Fundamentals of a Workplace First-Aid Program
- CPR and basic life support, including recognizing cardiac arrest, chest compressions, and rescue breaths.
- Bleeding control, direct pressure, tourniquet use, and recognizing shock.
- Injury management for burns, eye injuries, fractures, and head or spinal injuries.
- Environmental emergencies, including heat stroke, hypothermia, and chemical exposure or poisoning.
- Hazards specific to your workplace, whether electrical burns, chemical splashes, or falls from height.
Training must also cover consent and applicable Good Samaritan protections. Because these are hands-on skills, purely online courses generally won’t satisfy OSHA. A blended approach with online knowledge modules plus in-person skills practice under a qualified instructor is widely accepted, but the hands-on component where employees practice on mannequins and demonstrate competency cannot be skipped.
Designated Responders Trigger Hepatitis B Obligations
This is the piece many employers miss. Designating employees as first aid responders gives them “occupational exposure” to blood and other potentially infectious materials under the Bloodborne Pathogens standard, 29 CFR 1910.1030. OSHA draws a specific line here: training your entire office in CPR does not trigger the standard, but assigning specific people as your workplace first aid team does.8Occupational Safety and Health Administration. Applicability of Bloodborne Pathogens Standard to First Aid Providers at Electric Cooperatives
Once employees are designated, the employer must offer the Hepatitis B vaccination series at no cost, within 10 days of the assignment. If an employee initially declines but later changes their mind, the vaccination must still be made available for free as long as the employee remains in a role with occupational exposure.9Occupational Safety and Health Administration. Hepatitis B Vaccination Protection The employer also needs a written exposure control plan, must provide personal protective equipment like gloves and face shields, and must train designated responders on bloodborne pathogen hazards annually.
Instructor Credentials and How Often to Retrain
OSHA requires that instructors be “adequately trained” but doesn’t name specific certifying bodies for general industry. The construction standard is more explicit, recognizing the American Red Cross, the former U.S. Bureau of Mines, or equivalent programs.3Occupational Safety and Health Administration. 1926.50 – Medical Services and First Aid Training through the American Red Cross, American Heart Association, or National Safety Council is accepted across industries in practice.
OSHA does not mandate a specific retraining interval for general industry. Its Best Practices Guide recommends instructor-led retraining for life-threatening emergencies, specifically CPR and AED use, at least annually. A 2023 interpretation letter reinforced this position, noting that while OSHA “supports the annual CPR retraining intervals,” it does not technically mandate the frequency.10Occupational Safety and Health Administration. Frequency of Refresher Training for First Aid and CPR Certification cards from the Red Cross and American Heart Association typically expire every two years. Following those renewal cycles and adding annual CPR refreshers is the safest approach.
First Aid Kits, AEDs, and Eyewash Stations
Beyond trained personnel, 29 CFR 1910.151(b) requires adequate first aid supplies to be readily available. The regulation doesn’t list contents. OSHA references ANSI/ISEA Z308.1 as an example of minimum contents for a basic workplace kit, particularly for smaller worksites; the current version is ANSI/ISEA Z308.1-2021.11Occupational Safety and Health Administration. 1910.151 – Medical Services and First Aid The ANSI standard is a floor. A machine shop with cutting tools and metal shavings needs different supplies than an office. Inspect kits regularly; expired bandages, missing gloves, and empty cold packs are common citation triggers.
Corrosive chemical environments trigger a separate requirement under 1910.151(c): eyewash stations or body drenching facilities in the immediate work area for emergency flushing.
OSHA does not require AEDs, but the agency actively encourages installation. Sudden cardiac arrest kills roughly 10,000 people at work each year, and survival rates drop by about 10 percent for every minute without defibrillation.12Occupational Safety and Health Administration. Automated External Defibrillators (AEDs) If you install AEDs, train designated responders on their use alongside CPR, inspect the devices regularly to confirm batteries and pads haven’t expired, and check state law: many states require AED programs to operate under the direction of a licensed physician who reviews protocols and approves training.
Paying for Training and Keeping Records
When OSHA requires training, the employer pays. Employees cannot be required to cover the cost of mandatory first aid or CPR certification. The logging standard says so explicitly, requiring training “at no cost to the employee,” and the same principle runs through OSHA’s training requirements generally.4Occupational Safety and Health Administration. 1910.266 – Logging Operations Training time also counts as hours worked for wage purposes. Sending employees to a Saturday CPR class without paying them for that time creates a separate wage-and-hour problem.
OSHA does not prescribe a specific retention period for first aid and CPR training records under the general industry standard, but employers must be able to demonstrate compliance at any time. That means current documentation of who was trained, when they were certified, what skills were covered, and when recertification is due. Keep certification cards, sign-in sheets, and completion certificates for each employee throughout their tenure and for a few years after separation. For designated responders, document Hepatitis B vaccination acceptance or signed declination as part of your bloodborne pathogens exposure control plan.
What Non-Compliance Costs
Failing to have trained first aid providers when OSHA requires them is a citable violation. OSHA adjusts its maximum penalties for inflation annually. As of 2025, the maximum fine for a serious or other-than-serious violation is $16,550 per violation, and willful or repeated violations can reach $165,514 each.13Occupational Safety and Health Administration. US Department of Labor Announces Adjusted OSHA Civil Penalty Amounts for 2025
The financial penalties are the smaller concern. An OSHA investigation after a workplace fatality where no trained first aid responder was available can produce willful violation citations, wrongful death litigation, and reputational damage no fine amount captures. Training a handful of employees in CPR and first aid runs roughly $50 to $140 per person for an instructor-led course.
