OSHA first aid program requirements when there is no onsite nurse

Last updated 2026-07-11

What does OSHA actually require for first aid when there is no nurse on site?

The core rule is 29 CFR 1910.151(b): 'In the absence of an infirmary, clinic, or hospital in near proximity to the workplace which is used for the treatment of all injured employees, a person or persons shall be adequately trained to render first aid.' ^[1] That sentence is the whole ballgame for most small employers. No nurse required. No physician required. What is required is a trained first aider and a stocked kit.

The regulation does not define 'near proximity,' which is where a lot of confusion starts. OSHA has addressed this in letters of interpretation, and the agency's consistent position is that 3 to 4 minutes is the outside limit for emergency response to reach an injured worker. ^[2] If your nearest hospital, urgent care, or fire department EMT cannot get to your door inside that window, you need someone trained in first aid on every shift, period.

The other piece is 29 CFR 1910.151(a), which requires that medical personnel be available for advice and consultation on matters of employee health. For most small businesses this means having a relationship with a local physician or occupational health clinic, not a full-time medical staff. A signed consulting agreement or even a documented understanding with a local occupational health provider usually satisfies this.

One more thing worth knowing: 29 CFR 1910.151(c) requires that suitable facilities for quick drenching and flushing of the eyes and body be provided where employees may be exposed to injurious corrosive materials. That is a separate, equipment-based requirement that comes on top of the first aid person and kit requirements if your workplace handles caustic chemicals. If you are handling hazardous substances, your hazard communication program should connect directly to this.

What counts as 'near proximity' and how do you measure it?

Response time, not distance. OSHA has never put a mileage number in the regulation, and the agency's letters of interpretation are consistent: 3 to 4 minutes is the practical ceiling for EMS to reach an injured worker. ^[2] The reasoning is clinical. The probability of surviving a cardiac arrest drops roughly 10 percent per minute without defibrillation and CPR, and severe arterial bleeding can be fatal in under 5 minutes.

So the right way to evaluate your situation is to pick up the phone and actually time the local EMS response. Call your county or municipal EMS coordinator and ask for average response times to your address. If the honest average is over 4 minutes, you cannot lean on 'near proximity' as your defense. Many rural employers, manufacturing plants in industrial parks, and construction sites are in this position even when a hospital sits 5 miles away.

Urban employers sometimes assume they are covered because a hospital is close. Not always true. A hospital 0.8 miles away in a congested city may be a 7-minute drive at 8 a.m. Get the real data. Document it. If your analysis shows EMS can genuinely arrive in under 4 minutes, write that down in your first aid program and keep it with the program documentation.

For employers with multiple buildings or a large campus, OSHA expects the analysis for each separate work area, not the address as a whole. A worker injured in a back warehouse 400 yards from the front office where the trained first aider sits may have no 'near proximity' coverage in any real sense.

Who is required to be trained, and what training qualifies?

The standard says a 'person or persons shall be adequately trained.' It names no particular certification program. OSHA's letters of interpretation confirm that the agency accepts training courses meeting the content standards of the American Red Cross, American Heart Association, or the National Safety Council as adequate. ^[2] A basic first aid and CPR course from any of those organizations satisfies the training requirement.

The practical question is how many trained people you need. OSHA's position, stated in multiple interpretation letters, is that the trained person must be available at all times when employees are working. ^[3] That means if your trained first aider calls in sick, takes vacation, or works a different shift than the employees they cover, you have a gap. For a small business with a single location and two shifts, you likely need at least two trained employees, one for each shift.

Higher-hazard industries get more specific. OSHA's vertical standards sometimes layer on top of 1910.151. The construction standard at 29 CFR 1926.50 requires at least one trained person per job site. The logging standard at 29 CFR 1910.266 requires that each logging crew have someone trained in first aid on site at all times. If you are in one of those industries, read the vertical standard alongside 1910.151.

Certifications typically run 2 to 4 hours for a basic first aid course and 4 to 8 hours if CPR and AED training are combined. Red Cross and American Heart Association both offer blended online and in-person options now. Recertification is generally every 2 years for the skills components. OSHA does not set a recertification interval in the standard itself, so the provider's recommended interval is what auditors typically look to.

If you have supervisors or leads going through OSHA training or an OSHA 30 course, those courses include hazard recognition but do not substitute for hands-on first aid certification. They are different things.

What supplies must be in a workplace first aid kit?

The regulation at 29 CFR 1910.151(b) requires 'first aid supplies' but does not list specific items. The reference standard that fills that gap is ANSI/ISEA Z308.1, the American National Standard for Minimum Requirements for Workplace First Aid Kits. OSHA has cited this standard in letters of interpretation as the appropriate baseline for kit contents. ^[4]

ANSI Z308.1 splits kits into Class A and Class B. Class A covers the minimum for low-hazard environments. Class B is built for higher-hazard worksites and carries more items and higher quantities. The 2021 revision updated the required item list. If your kit was bought before that and has never been reviewed, check it against the current list.

Here are the core Class A minimums from ANSI Z308.1-2021:

Item	Minimum Quantity (Class A)
Absorbent compress (32 sq in or larger)	1
Adhesive bandages (1" x 3")	16
Adhesive tape (2.5 yd minimum)	1
Antiseptic, 0.5 g application	10
Breathing barrier (CPR)	1
Burn dressing (minimum 4" x 4")	1
Burn treatment (0.5 g application)	6
Cold pack	1
Eye covering with means of attachment	2
Eye/skin wash (1 fl oz)	1
First aid guide	1
Hand sanitizer (0.5 g)	6
Medical exam gloves	2 pair
Roller bandage (2" width)	1
Roller bandage (4" width)	1
Sterile pad (3" x 3" minimum)	2
Triangular bandage (40" x 40" x 56")	1

Kit location matters too. OSHA expects kits to be readily accessible to all employees, clearly marked, and not locked away in a back office. For multi-floor facilities or large worksites, one kit per floor or one per major work zone is the practical standard, though the regulation sets no specific ratio. Inspect kits monthly, replace used or expired items right away, and log those inspections in writing.

A basic commercial kit is not enough on its own if your site has specific hazards. A shop that welds needs burn dressings rated for that exposure. A facility handling acids needs neutralizing eye wash and a drench shower under 1910.151(c). A lockout tagout environment with energy control hazards should think through crush and amputation scenarios when stocking the kit. Match the kit to your actual hazard profile.

Do you need a written first aid program, and what should it include?

OSHA's 29 CFR 1910.151 does not use the phrase 'written program' the way 1910.147 (lockout/tagout) or 1910.1200 (hazard communication) do. But that does not mean you can skip documentation. A few things make a written program functionally required even if this single standard does not literally mandate it.

First, if OSHA shows up and finds an injured worker with no trained responder on site, no stocked kit, and no documentation that you ever thought about this, the citation writes itself. A written program is your primary evidence that you took the requirement seriously and built a real system. Second, several state plans have pushed the written program requirement beyond the federal floor. California's Title 8 section 3400, for example, requires an Injury and Illness Prevention Program that addresses first aid directly. ^[5] If you are in a state-plan state, check the state rule.

Third, and most practically, a written program is how you make sure the system works when you are not there. It answers: who is trained, when their certification expires, where the kit is, who restocks it, what the emergency numbers are, and what happens when the trained person is absent.

A first aid program document does not need to be long. A single page covering these elements is fine:

• Scope (which locations and shifts this covers)
• Name(s) of trained first aiders and certification expiration dates
• Kit location(s) and inspection schedule
• Emergency contact numbers (site-specific, more than 911)
• Procedure for when the trained person is absent
• Documentation of your near-proximity analysis or EMS response time
• Names of anyone with AEDs on site, if applicable

If you need to get this written fast, SafetyFolio's safety program generator can produce a first aid program framework in about 15 minutes by walking you through the site-specific questions rather than having you start from a blank page.

Once the program exists, tie it to your incident report process. A first aid event that gets handled well and documented properly is the foundation for your OSHA 300 log decisions, and those records are what an inspector will look at first.

What are the AED requirements under OSHA?

Federal OSHA does not mandate AEDs under 29 CFR 1910.151 for general industry. In a 2001 letter of interpretation the agency said that while OSHA 'strongly encourages' AED programs, the standard does not require employers to provide them. ^[3] That said, several states and many local jurisdictions have their own AED placement laws for certain business types, so state law may apply independently of federal OSHA.

From a practical standpoint, if you have more than 25 employees or your worksite has any history of cardiac events, an AED is a reasonable buy. The devices cost between $1,200 and $2,000 for a mid-range unit, though prices vary. The American Heart Association reports that survival rates for cardiac arrest rise from about 5 percent with CPR alone to 49-75 percent when defibrillation happens within 3 to 5 minutes. ^[6] If EMS cannot reach your site in time, an AED with a trained operator may be the only thing between an incident and a fatality.

If you do place AEDs, document their location in your first aid program, make sure trained employees know where they are, and maintain them per manufacturer requirements. An AED sitting in a locked cabinet with a dead battery and no trained users is liability without benefit.

How does OSHA enforce first aid requirements, and what does a citation look like?

OSHA most often cites 29 CFR 1910.151(b) as an 'other than serious' violation when there is no trained first aider or no kit, assuming no one was actually injured in the incident that prompted the inspection. Penalties for other-than-serious violations start at $1,144 per violation as of 2024 and can run higher with gravity adjustments. ^[7] If the violation contributed to an injury, the severity goes up.

This usually surfaces through records and interviews. An OSHA compliance officer will ask supervisors who the trained first aider is on the current shift, ask to see the first aid kit, check its contents against a reasonable standard, and ask whether the nearest hospital can respond in time. If the supervisor does not know the answer to 'who is the trained first aider right now,' that is a problem.

OSHA also uses the general duty clause (Section 5(a)(1) of the OSH Act) to address first aid gaps not precisely covered by a specific standard. If your industry has specific hazards (confined spaces, high-voltage electrical work, chemical exposure) and your first aid readiness does not match those hazards, a general duty clause citation is possible even where 1910.151 is technically met on paper.

Small employers under 10 employees are not exempt from these requirements. OSHA's small business exemption from programmed inspections does not erase the substantive standards. If someone files a complaint or there is an injury, the standard applies.

Are there different first aid rules for construction versus general industry?

Yes. Construction falls under 29 CFR 1926.50 rather than 29 CFR 1910.151, though the practical requirements are similar. The construction standard requires first aid supplies approved by a consulting physician on every job site, and at least one trained person present at each job site where workers are exposed to injury. ^[8]

The construction standard is slightly more specific than 1910.151 in a couple of ways. It explicitly requires that in the absence of an infirmary or clinic in near proximity, a communication system be available for contacting emergency services. It also references the need for prompt transportation to a hospital if needed. For remote construction sites, that means thinking through medical transport in advance, not after someone is hurt.

For general industry, 1910.151 is the baseline. But some OSHA vertical standards in general industry carry their own first aid provisions. The standards for logging (1910.266), hazardous waste operations (1910.120), and fire brigades (1910.156) all have specific first aid or emergency medical requirements that go beyond the general standard. If your operation falls under one of those, read both the vertical standard and 1910.151.

Maritime industries (shipyards, marine terminals, longshoring) have their own Part 1915, 1917, and 1918 standards with specific first aid requirements. Federal agencies fall under 29 CFR Part 1960. And if you have employees working at a location covered by state-plan OSHA, the state standard may be stricter than federal.

What records do you need to keep for your first aid program?

OSHA's recordkeeping standard at 29 CFR 1904 requires you to record work-related injuries and illnesses on an OSHA 300 log if they result in days away from work, restricted duty, job transfer, medical treatment beyond first aid, loss of consciousness, or diagnosis of a significant injury by a licensed healthcare professional. ^[9]

The phrase 'beyond first aid' is defined in 1904.7(a), which lists a specific set of treatments that count as 'first aid' for recordkeeping purposes. Cleaning wounds, applying bandages, using nonprescription medications at nonprescription strength, tetanus immunizations, drilling fingernails to relieve pressure, and a few other treatments are all classified as first aid under 1904.7 and do not trigger a recordable incident. That list matters. If your trained first aider handles the injury on site using only those interventions, and the employee returns to full duty, you likely do not have a recordable case.

For the first aid program itself (as distinct from the injury log), keep records of:

• Training certificates for all trained first aiders, including the date of training and expiration date
• Kit inspection logs (who checked it, when, what was replaced)
• Any formal documentation of your near-proximity EMS analysis
• Your written first aid program document itself

OSHA does not set a specific retention period for first aid program records beyond the 5-year retention period for 300/300A logs. Keeping training and inspection records for at least 3 years is a reasonable practice. If a first aid event later becomes a recordable injury (sometimes a seemingly minor injury turns out to be more serious after a few days), having the contemporaneous documentation of what your first aider did and with what training matters a great deal.

How do you handle first aid coverage across multiple shifts or when the trained person is out?

This is the most common practical gap OSHA finds in small businesses. The employer trained one person, that person got promoted, transferred, or quit, and nobody noticed the gap until an inspector asked. The fix is straightforward but takes discipline.

Train more people than you think you need. If you have two shifts, train at least two people per shift, not one. If you have 15 employees spread across three departments, train a first aider in each department so coverage does not hinge on one person's physical location in the building. A first aid course is not expensive, typically $50 to $100 per person for a group course, and recertification every two years keeps the cost manageable.

Build a coverage protocol into your written program. Name a primary first aider for each shift and a backup. When the primary is out, the backup is on duty. Document shift coverage in your daily operations notes or your sign-in system. If you genuinely cannot cover a shift with an internal trained person, explore options like a staffing arrangement with a local occupational health service that provides on-call support.

For very small employers (2 to 5 workers), some OSHA letters of interpretation have acknowledged that it may not always be possible to have a separate trained first aider available at every moment (for example, in a 2-person shop where both workers are alone on alternating days). The expectation in those cases is still that the workers themselves have first aid training, and that the near-proximity analysis supports reliance on emergency services for anything beyond self-care. Do not use this as an excuse to train nobody. The intent is clear: someone with first aid training must be reachable.

What should be in a first aid response procedure for common workplace injuries?

OSHA does not script the clinical response. That is the job of the first aid training itself. But your written program should at least point to the emergency numbers and protocols your workers should follow, and the trained first aider should be comfortable with the practical steps for the most likely injury types in your environment.

For most general industry small businesses, the highest-frequency injuries are lacerations, eye injuries, chemical burns, falls, and musculoskeletal strains. BLS Injuries, Illnesses, and Fatalities data shows that cuts and lacerations and slips, trips, and falls consistently account for a large share of nonfatal occupational injuries requiring days away from work. ^[10]

For chemical exposure injuries, your response procedure should tie directly to your hazard communication program and the safety data sheets for the chemicals on site. The SDS for any hazardous chemical includes a Section 4 on first aid measures. Your first aider should know where the SDS binder or digital SDS system is and how to use it quickly. In a pinch, calling Poison Control (1-800-222-1222) is always an option and costs nothing.

For suspected fractures and spinal injuries, first aid training teaches stabilization, not movement. The protocol is to call EMS and keep the person still. Your written program should include the site address formatted for quick reading over the phone, because in a stressful moment a worker may not recall the exact street address.

For cardiac events, chest compressions and AED use (if you have one) are the actions that change outcomes. Every minute without defibrillation in a ventricular fibrillation cardiac arrest reduces survival by about 10 percent, per American Heart Association data. ^[6] That is why the near-proximity analysis matters so much. If EMS is 8 minutes away and you have no AED, the math is not good.

How do state-plan OSHA states change these requirements?

Twenty-two states and two territories run their own OSHA programs approved by federal OSHA. ^[11] These state plans must be 'at least as effective' as federal OSHA, which means they can be stricter. A few places where state plans commonly add requirements beyond 29 CFR 1910.151:

California's Cal/OSHA (Title 8, Section 3400) requires employers to have an 'adequate number of persons' trained in first aid when medical services are not immediately available. California also has specific language requiring the first aid training to be completed 'before the employee is assigned to work.' The state's Injury and Illness Prevention Program requirement also expects first aid procedures to be addressed in writing. ^[5]

Washington (L&I) requires a trained first aider to be available whenever hazardous work is in progress, with specific requirements for high-hazard industries. Oregon OSHA takes a similar at-least-as-stringent approach.

In practice, if you are in a state-plan state, look up your state's equivalent standard before you finalize your program. The federal 1910.151 gives you the floor. Your state rule tells you if the floor is higher. OSHA keeps a directory of state plans at osha.gov/stateplans. ^[11]

Frequently asked questions

Does OSHA require a written first aid program?

Not in explicit terms under 29 CFR 1910.151, which does not use the phrase 'written program.' But you need documentation to prove compliance during an inspection, and several state-plan states do require a written program. California's IIPP requirement effectively mandates it. Every employer subject to 1910.151 should have a written program as a practical matter, even if only one page.

How many employees do you need before OSHA first aid requirements apply?

There is no employee count threshold in 29 CFR 1910.151. The standard applies to all employers in general industry regardless of size. A 3-person machine shop and a 3,000-person factory are both covered. OSHA's programmed inspection schedule gives small employers a lower probability of routine inspection, but the substantive requirements are the same.

Does a first aid kit have to be a specific brand or OSHA-approved product?

No. OSHA does not approve specific brands. The standard requires 'first aid supplies,' and OSHA's letters of interpretation point to ANSI/ISEA Z308.1 as the appropriate content standard. Any commercial kit labeled as meeting ANSI Z308.1 Class A or Class B is a defensible choice. Whatever you buy, inspect it regularly and replace expired or used items.

Can CPR-only training satisfy the 29 CFR 1910.151 first aid training requirement?

No. CPR training alone does not cover the range of injuries addressed by first aid training. OSHA's position is that 'adequately trained' means training that covers a broad set of injury responses, more than cardiac arrest. A combined first aid, CPR, and AED course from the Red Cross, American Heart Association, or National Safety Council is the practical standard.

What happens if my only trained first aider quits?

You have a compliance gap. If an OSHA inspection or a workplace injury occurs and you cannot identify a trained first aider on the current shift, you are exposed to a citation under 1910.151(b). The practical fix is to cross-train multiple employees so that no single departure creates a gap. Update your written program whenever a first aider's status changes.

Does OSHA require an AED in the workplace?

Federal OSHA does not require AEDs under 29 CFR 1910.151 for general industry. A 2001 OSHA letter of interpretation says the agency 'strongly encourages' AED programs but does not mandate them. Some state or local laws may require AEDs in certain settings. Check your state's occupational safety and public health statutes independently of the federal standard.

Is a first aid event recordable on the OSHA 300 log?

Generally no, if the injury is treated exclusively with measures that qualify as 'first aid' under 29 CFR 1904.7(a). That list includes bandages, wound cleaning, over-the-counter pain medications at OTC strength, and a handful of other specific treatments. If the injured worker needs prescription medication, stitches, days away from work, or restricted duty, it becomes recordable.

How do I document the near-proximity analysis for my workplace?

Contact your local EMS provider or county emergency management office and ask for average response times to your address. Get it in writing if possible, or document your inquiry and their verbal response with a date and contact name. Write a short paragraph in your first aid program summarizing the result and what that means for your coverage requirements. Review and update it annually or if EMS resources in your area change.

What first aid training is required for construction sites under OSHA?

Construction falls under 29 CFR 1926.50, which requires first aid supplies approved by a consulting physician and at least one trained first aider on every job site where workers are exposed to injury. If the site is not in near proximity to medical services, a communication system for contacting emergency services is also required. The requirement applies per job site, not per company.

Does OSHA require first aid training to be repeated or recertified?

The standard at 29 CFR 1910.151 does not set a specific recertification interval. OSHA's practical expectation, reflected in letters of interpretation, is that training be current. Red Cross and American Heart Association certifications typically expire after 2 years. Following the certifying organization's recommended renewal cycle is the defensible standard and what auditors reference.

Are there specific OSHA first aid requirements for offices and low-hazard workplaces?

Yes, 1910.151 applies to offices too. The practical requirements scale with hazard: an office with no chemical exposure or heavy equipment still needs a stocked first aid kit, a trained first aider if EMS is not in near proximity, and documented coverage. The kit can meet Class A minimums rather than the higher-quantity Class B, but the requirement exists regardless of the risk level.

Can a manager or supervisor count as the trained first aider?

Yes, as long as they have completed a legitimate first aid and CPR course and their certification is current. Title does not matter; training status does. The practical problem with relying solely on a manager is that managers travel, take time off, and may not be physically present at an incident. Training additional non-management employees is better coverage.

What is the penalty for violating OSHA's first aid standard?

OSHA typically classifies 1910.151 violations as 'other than serious,' with penalties starting at $1,144 per violation as of 2024. Gravity-based adjustments can increase penalties. If the violation is linked to a worker injury or if OSHA finds a willful or repeated pattern, penalties increase significantly. Employers with 10 or fewer employees qualify for penalty reductions but are not exempt from the standard.

Do remote workers or work-from-home employees trigger OSHA first aid requirements?

OSHA has historically taken the position that it does not conduct inspections of home offices and that employers are not responsible for the home office environment the way they are for a traditional workplace. However, if employees travel to client sites, warehouses, or other work locations away from a central office, those locations must have first aid coverage. Remote work in a true home setting is a gray area that OSHA has not resolved by rulemaking.
