- OSHA 1910.151 requires a trained first-aider when EMS is not close by, plus first aid supplies suited to the workplace.
- No fixed ratio. The rule is coverage: someone trained available whenever medical help is not within a few minutes.
- CPR is recommended, not universally mandated; AEDs are encouraged, not federally required. Some industries require both.
- Online-only certificates are commonly rejected. Choose in-person or blended with a hands-on skills check.
- Good Samaritan laws protect reasonable rescuers in every state. The answers below cover who pays, industry rules, and renewal.
First aid at work in the US is governed by OSHA, which sets a baseline rather than a one-size rule: employers need trained first-aiders and supplies when medical help is not close by, and some industries go further. This guide answers the questions US workers and employers ask most about workplace first aid, CPR, and OSHA, from how many first-aiders you need to who pays.

OSHA First Aid Requirements
What OSHA 1910.151 asks of US employers, and who must be trained.
Q1: Does OSHA require first aid training in the workplace?
A: OSHA 1910.151 requires that a trained first aid provider be available when there is no clinic or hospital near the workplace for treating injured employees. Where serious injuries are possible, EMS should reach the site within a few minutes; if not, someone on site must be trained. Adequate first aid supplies must also be readily available.

Q2: What is OSHA standard 1910.151?
A: It is OSHA’s Medical Services and First Aid rule. It requires ready access to medical advice, a trained first-aid person when professional care is not nearby, and readily available first aid supplies appropriate to the workplace. It is the baseline most US employers work from.
Q3: How many employees need first aid training under OSHA?
A: OSHA does not set a fixed number or ratio. The requirement is coverage: at least one trained first-aider available whenever EMS cannot reach the site quickly. Many employers train several people so every shift and location is covered.

Q4: What are OSHA first aid kit requirements?
A: OSHA requires first aid supplies adequate for the specific workplace, kept readily available. Many employers stock kits meeting the ANSI/ISEA Z308.1 guideline as a practical benchmark, then add items for their particular hazards. Higher-hazard sites need more.
Q5: Does OSHA count office jobs the same as high-hazard sites?
A: No. OSHA recognizes a longer response time, up to about 15 minutes, may be reasonable for low-risk offices, while sites with fall, electrocution, or amputation risks need EMS or a trained first-aider within 3 to 4 minutes. Your industry sets how strict the rule is.
CPR & AED at Work
Whether US employers must provide CPR training and defibrillators.
Q6: Does OSHA require CPR training at work?
A: OSHA does not mandate CPR for every workplace, but its first aid training guidelines recommend CPR as a program element, and some standards and industries require it. Where a trained first-aider is required, CPR is usually part of that training. Check your industry’s specific rule.
Adapted from real questions asked on: Reddit
Q7: Does OSHA require an AED in the workplace?
A: No federal OSHA rule requires an AED in general workplaces, though OSHA encourages them. Many employers install one because rapid defibrillation dramatically improves survival. If you provide an AED, staff should be trained, and AED use is part of standard CPR/AED certification.
Q8: What first aid or CPR certification do most US jobs require?
A: Non-clinical roles usually accept a CPR/AED or first aid card such as Heartsaver or American Red Cross. Healthcare roles require BLS. Safety-sensitive jobs often name first aid and CPR together. Read the posting, then book the matching course.
Q9: Is an online-only first aid certificate OSHA compliant?
A: A fully online certificate does not demonstrate the hands-on skills OSHA-aligned training expects, and many employers reject it. A blended course, with online theory and an in-person skills session, is the compliant route. Look for training with a practical skills check.
Employer Duties: Who Pays & Provides
Whether US employers must arrange and pay for training.
Q10: Does my employer have to provide first aid and CPR training?
A: If a trained first-aider is required at your site and none is otherwise available, the employer is responsible for meeting that duty, which usually means arranging training. How it is delivered varies, so ask whether your employer provides the course or expects you to arrive certified.
Adapted from real questions asked on: Reddit
Q11: Do employers have to pay for required first aid training?
A: When training is a job requirement, many US employers cover the cost and the time as part of their safety obligations, and on-site group training is the common route. It is not a universal rule, so confirm before booking. See group training to certify a team together.
Q12: Can I put a workplace first aid certificate on my resume?
A: Yes. First aid and CPR certification is a strong resume credential for customer-facing, trades, security, childcare, and safety roles. List the exact course, provider, and expiration so employers see it is current. Our careers guide covers which level fits which job.
Industry Rules & Good Samaritan
Sector-specific requirements and liability for helping.
Q13: Do construction and industrial jobs require first aid and CPR?
A: Often, yes. Construction and industrial employers commonly require first aid and CPR because of the hazards and distance from medical care, and some contracts specify it. First aid and CPR are portable credentials you can complete before you apply.
Q14: What are OSHA bloodborne pathogens training rules?
A: OSHA’s Bloodborne Pathogens standard (1910.1030) requires training and protections for employees with reasonably anticipated exposure to blood, such as healthcare and some first-responder roles. Many workplace first aid courses include bloodborne pathogens basics.
Q15: Can I be sued for helping someone in an emergency at work?
A: Every US state has a Good Samaritan law that protects people who voluntarily help in an emergency, as long as they act reasonably and within their training. Successful suits against ordinary rescuers are rare. This is general information, not legal advice; on the job, follow your workplace response plan.
Adapted from real questions asked on: Reddit
Q16: How often should workplace first-aiders recertify?
A: Renew before the two-year expiration on AHA and American Red Cross cards to stay compliant, since skills fade and most employers will not accept a lapsed card. Booking a group renewal keeps a whole team on the same date. Find dates on our course page.
Questions were selected from US search demand and public forum discussions in communities such as r/WorkplaceSafety and r/legaladvice, and from Google Search Console data for c2cfirstaidaquatics.com/us. Answers were edited for clarity, aligned with OSHA 1910.151 and related standards, and reviewed by a certified instructor. First aid rules vary by industry, hazard level, and state, so confirm the exact requirement for your workplace.
OSHA requires trained first-aiders and supplies whenever emergency care is not nearby, with the standard scaling to your hazards. Use an in-person or blended course (not online-only), keep certificates current every two years, and for teams, on-site group training is the fastest way to stay compliant.
