OSHA First Aid Requirements: What Employers Must Provide and How to Comply

OSHA first aid requirements come down to one question: if someone is hurt at work, can they get help quickly enough? The rules do not set a headcount of certified employees or name an approved course. They require that your response matches your hazards and your distance from medical care. That makes the standard flexible, and it also makes it easy to misread.

What the OSHA First Aid Standard Actually Says

For general industry, the rule is 29 CFR 1910.151. It has three short parts. Paragraph (a) says the employer must ensure that medical personnel are readily available for advice and consultation on matters of plant health. Paragraph (b) says that, in the absence of an infirmary, clinic, or hospital in near proximity to the workplace, a person or persons must be adequately trained to render first aid, and that adequate first aid supplies must be readily available. Paragraph (c) covers eyewash and drenching equipment, discussed later in this article.

Construction has its own rule, 29 CFR 1926.50. The logic is similar, but it is more specific. It requires first aid supplies, trained first aid providers when there is no nearby medical facility, and a way to reach emergency help, including posted emergency telephone numbers and a means of transporting an injured worker. If you run both general industry and construction operations, you need to know which rule governs each site.

Read the wording closely

The standard is performance-based. Look at what it leaves out:

No minimum number of trained employees.

No required course name, hour count, or provider.

No fixed distance or time written into the regulation text itself.

The deciding phrase is "near proximity." If a hospital, clinic, or infirmary is close enough to treat your workers promptly, the training duty in paragraph (b) may not apply. If it is not, you must have trained responders on site. The supply duty applies either way.

Consider two illustrations. A small office in a building across the street from a hospital faces a very different situation from a crew working on a remote job site 40 minutes from the nearest emergency room. The first may reasonably rely on outside care for most injuries. The second must have trained people and equipment on site, because no one else can get there in time. Both are governed by the same sentence of regulation, and both can be compliant with very different setups.

Because the standard is open-ended, inspectors and OSHA letters of interpretation fill in the details. The next section covers how.

What "Near Proximity" Means for Your Workplace

OSHA has addressed this in letters of interpretation, and its guidance has long tied the answer to the severity of the injuries a workplace could produce. As commonly cited, where serious injuries such as life-threatening bleeding, cardiac arrest, or suffocation are possible, emergency care should be reachable within roughly 3 to 4 minutes. For workplaces where only less severe injuries are plausible, a response time of up to about 15 minutes has been treated as acceptable. The construction standard's appendix guidance reflects the same thinking. Check the current wording on OSHA's website before you rely on these figures, since interpretation letters can be updated or superseded.

Those windows are short. Think about what has to happen in 3 to 4 minutes: someone recognizes the emergency, calls for help, starts bleeding control or CPR, and retrieves an AED if one is available. An ambulance almost never arrives that fast, which is exactly the point.

The common mistake: 911 is not the plan

Many employers assume that calling 911 satisfies the rule. It does not, because EMS travel time alone usually exceeds the window for a life-threatening event. Trained coworkers bridge the gap until paramedics arrive.

Examples across workplaces

Warehouse with forklift traffic: crush injuries, fractures, and severe bleeding are realistic. Trained responders on every shift are warranted.

Landscaping crew: work is spread across properties, often away from hospitals, with cuts, heat illness, and equipment injuries. Each crew vehicle needs a trained person and a kit.

Pool facility: drowning and cardiac events demand immediate action, which is why lifeguard-level training and rescue equipment are standard practice.

Retail store: hazards are lower, but a customer or employee can still collapse. A few trained staff and an AED are sensible even where injuries are mostly minor.

Factors to weigh

Work through the injuries most likely on your site, your shift patterns (nights and weekends often have the thinnest coverage), how remote each location is, and the real EMS response times in your area. Ask your local dispatch or fire department what to expect, and write down what you learn. That record supports your decision if an inspector asks.

First Aid Training: Who Needs It and What It Should Cover

OSHA does not certify courses or approve providers, so there is no such thing as an "OSHA-approved" CPR card. What it expects is that your designated responders are adequately trained. Its first aid training guidance has historically pointed to nationally recognized programs such as those from the American Red Cross and the American Heart Association as meeting that expectation. Confirm the current language in OSHA's first aid guidelines, but the practical takeaway is stable: choose a recognized program with hands-on skills practice.

What the training should include

Assessing the scene and recognizing when to call for help

Bleeding control, including direct pressure and tourniquet use

CPR and AED use for adults, and children or infants if your workplace serves them

Burns, choking, shock, and sudden illness such as seizures or diabetic emergencies

Hazards specific to your site, such as chemical exposure, heat illness, or machinery injuries

Generic classes cover the first four well. The last item is where an instructor who understands your workplace adds value, because a course built around your actual hazards is more useful than a generic one.

Certification length and skills retention

CPR and First Aid certifications from both the American Red Cross and the AHA typically run two years. Treat that as a ceiling, not a comfort zone. Skills fade, and a responder who took a class 23 months ago may hesitate when it counts. Short skills refreshers and drills between certifications keep people ready.

Bloodborne pathogens

If first aid is part of an employee's assigned duties, they are likely covered by the Bloodborne Pathogens standard, 29 CFR 1910.1030. That means training on exposure risks, protective equipment, and post-exposure procedures, with annual refreshers. Many employers overlook this when they train a "designated responder."

How many people to train

OSHA gives no number, so build in margin. Aim for at least two trained responders per shift, more on large or spread-out sites. Vacations, sick days, turnover, and shift changes will otherwise leave gaps. Track certification expiration dates in one place and schedule renewals ahead of time.

First Aid Kits and Emergency Equipment

Paragraph 1910.151(b) requires "adequate" first aid supplies that are "readily available." OSHA does not itemize them in the general industry rule. The construction standard's Appendix A to 1926.50 refers to ANSI/ISEA Z308.1 as a minimum standard for kit contents, and OSHA treats it as a benchmark for general industry too. As of 2026, check which edition is current, since the standard is revised periodically, and buy kits that state compliance on the label.

Class A and Class B kits

ANSI/ISEA Z308.1 defines two classes of kit:

Class A covers common workplace injuries such as minor cuts, scrapes, sprains, and minor burns.

Class B carries a broader and larger range of supplies for more complex or higher-risk environments, such as manufacturing, construction, or large crews.

A low-hazard office may do well with Class A kits. A fabrication shop or warehouse should consider Class B, and may need supplemental items such as tourniquets and hemorrhage control supplies based on its hazards.

Beyond the kit

Paragraph 1910.151(c) requires suitable facilities for quick drenching or flushing of the eyes and body wherever employees may be exposed to injurious corrosive materials. A bottle of eyewash in a kit is not a substitute. Fixed or plumbed stations, tested regularly, are the norm.

AEDs are different. OSHA does not generally mandate them, but it recommends them as a best practice, and survival from sudden cardiac arrest depends heavily on how quickly a shock is delivered. If your workplace is in a hazard category where cardiac events are plausible, or if you have many employees or public visitors, an AED belongs in your plan.

Practical checks

Inspect every kit monthly and keep a dated log.

Replace expired and used items right away.

Place kits near the hazards, not locked in an office.

Mark kit and AED locations with clear signage.

Assign one named person to restock.

Building a Compliance Plan and Avoiding Common Citations

A workable plan follows a clear sequence:

Assess the hazards at each site and the injuries they could cause.

Find out realistic emergency response times for each location.

Decide how many responders you need per shift, with backup.

Select a recognized training provider and schedule classes.

Stock kits and equipment, and place them where hazards are.

Document everything: assessments, training rosters, expiration dates, inspection logs.

Gaps tend to repeat across workplaces: expired certifications, no trained person on the night shift, kits that are empty or locked, and no one responsible for restocking. Each one is easy to prevent with a calendar and a named owner.

Pair first aid with an emergency action plan. Post emergency numbers and the exact site address where workers can see them, and make sure people know who calls 911 and who meets the ambulance. On multi-building sites, a responder who can direct EMS to the right door saves minutes.

State plans can be stricter

Federal OSHA is not the only authority. Washington (through L&I, with first aid requirements in WAC 296-800-15005), California (Cal/OSHA, Title 8 section 3400), and Oregon (Oregon OSHA) all run state plans with their own first aid rules. These are often more specific than the federal text, for example on supplies, training, or responder availability. As of 2026, verify the current text with your state agency before finalizing your plan.

Where Taylored Instruction fits

Taylored Instruction offers in-person and on-site CPR and First Aid classes through both the American Red Cross and the American Heart Association, plus AED sales, for employers in Clark County, the Portland metro area, and San Luis Obispo. Classes can be shaped around your workplace's actual hazards.

Audit Your Coverage Before an Injury Does It for You

OSHA's standard asks for fast, trained response matched to the hazards you actually have. Walk your sites, count the trained responders on each shift, check your kits and expiration dates, and compare your response-time assumptions with reality. Wherever you find a gap, fix it now.

Don't wait until an emergency happens. Get the life-saving certification you need today. Register for a CPR, First Aid, or Lifeguarding class and gain the confidence and skills to respond when it matters most.
