The Role of a First Aider at Work: Responsibilities and Expectations

Every workplace has its risks. Whether it’s a slip in the office, a cut in the kitchen, or a fall on a construction site, accidents happen—and when they do, having someone trained and ready to respond can make all the difference. That’s where a First Aider comes in.

A First Aider is more than just someone who knows how to use a bandage. They’re a trained individual who plays a vital role in protecting the health, safety, and wellbeing of their colleagues. Their presence not only meets legal requirements but also provides peace of mind to staff and employers alike.

But what exactly does the role involve? What are the legal and practical responsibilities of a workplace First Aider? And what should employers and employees expect from someone in this role?

In this post, we’ll explore the expectations, duties, and day-to-day responsibilities of a First Aider at work—giving you a clear understanding of this essential role in any organisation.

What Is a First Aider?

A First Aider is someone who has successfully completed recognised First Aid training—typically either Emergency First Aid at Work (EFAW) or the more comprehensive First Aid at Work (FAW) course. They are equipped with the knowledge and practical skills to provide initial assistance in the event of illness or injury until professional help can be obtained or the situation is resolved.

In many workplaces, First Aiders are volunteers or nominated staff members who take on this extra responsibility alongside their regular duties. However, it’s not a casual add-on. Being a First Aider comes with significant responsibility, legal implications, and the potential to directly impact the health outcomes of colleagues or customers.

Why the Role Matters

The importance of a First Aider in the workplace cannot be overstated. In those crucial first minutes after an incident, a calm, trained individual can prevent further harm, reduce recovery time, and—quite literally—save lives.

In the UK, the Health and Safety (First-Aid) Regulations 1981 require employers to provide “adequate and appropriate” First Aid provision. This includes equipment, facilities, and personnel. While not every workplace legally requires a trained First Aider on site, most do—especially those with more than a few employees, those operating in higher-risk environments, or those serving the public.

By appointing trained First Aiders, businesses demonstrate a commitment to employee welfare, workplace safety, and legal compliance.

The Responsibilities of a First Aider

At its core, the role of a workplace First Aider is about responding effectively to accidents and emergencies.

But in practice, it includes a broad range of responsibilities—some practical, others administrative or advisory. Here’s a breakdown of what’s typically expected:

Immediate Response to Injuries and Illnesses

The primary duty of a First Aider is to provide initial assistance when someone is injured or becomes ill. This includes:

• Assessing the situation quickly and calmly
• Ensuring the safety of the casualty and bystanders
• Performing life-saving interventions like CPR if needed
• Controlling bleeding, dressing wounds, and supporting broken limbs
• Monitoring the casualty’s condition until professional help arrives
• Reassuring and communicating with the injured person throughout

Speed, clarity, and confidence are essential during these moments, and First Aid training ensures individuals are prepared to act effectively under pressure.

Using First Aid Equipment Correctly

A First Aider should be familiar with the contents of the workplace First Aid kit and know how to use each item. This includes:

• Applying sterile dressings and bandages
• Using gloves and face shields to prevent cross-contamination
• Knowing the location and proper use of AEDs (defibrillators)
• Understanding how to handle specific First Aid items like burn dressings or cold packs

Regular practice, refresher training, and ongoing awareness are key to maintaining these skills.

Reporting and Record Keeping

Accurate record keeping is an important part of a First Aider’s role. After treating a casualty, the First Aider should complete an accident report that includes:

• Date, time, and location of the incident
• Nature of the injury or illness
• Actions taken and any equipment used
• Details of any referrals to external medical services
• Witnesses or other people involved

These records are useful for internal review, legal compliance, and potential insurance claims. In some cases, they may also be required under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations).

Maintaining First Aid Kits and Equipment

While the employer is ultimately responsible for providing First Aid equipment, many First Aiders are asked to check the contents of kits regularly and ensure they are fully stocked, clean, and within expiry dates. This includes:

• Replacing used or expired items
• Ensuring kits are accessible and clearly marked
• Reporting any missing equipment or hazards
• Ensuring the AED, if present, is operational and maintained

Keeping First Aid supplies in good order is crucial to ensuring a fast, effective response when the time comes.

Advising on Safety and Emergency Procedures

Although First Aiders are not safety officers, they often play a supporting role in general workplace safety. With their training and insight, they can:

• Advise colleagues on minor safety risks
• Support fire wardens or evacuation procedures
• Assist in updating emergency contact lists
• Contribute to reviews of the company’s First Aid needs assessment

Their presence is a valuable asset not only during emergencies but as part of a broader culture of health and safety.

Limitations of the Role

While First Aiders are trained and capable, their role does have limits. They are not medical professionals and should not attempt to diagnose conditions, administer medications (unless specifically trained and authorised), or provide treatment beyond their training.

It’s important that both First Aiders and employers understand these boundaries. In legal terms, First Aiders are protected when they act in good faith within the scope of their training and company policy. This is known as the “Good Samaritan” principle, and it’s designed to encourage people to help without fear of legal repercussion, provided their actions are reasonable.

What Employers Should Provide

In order for First Aiders to do their job effectively, employers need to support them with the right resources. This includes:

• Time to complete and refresh First Aid training
• Access to fully stocked First Aid kits
• Clear protocols for responding to incidents
• Permission to act confidently and without unnecessary delays
• A supportive culture that recognises and respects the First Aider’s role

Employers must also conduct regular First Aid needs assessments, especially when there are changes to staff numbers, building layout, work activities, or hours of operation.

Training and Certification

To become a workplace First Aider, an individual must complete a course approved by a recognised training provider. The two main options are:

• Emergency First Aid at Work (EFAW) – a one-day course suitable for low-risk workplaces
• First Aid at Work (FAW) – a comprehensive three-day course covering a broader range of injuries, illnesses, and emergency scenarios

Certificates typically last for three years, after which refresher or requalification courses are required. It’s also recommended that First Aiders attend annual refresher sessions to maintain confidence and competence.

At IJL First Aid Training North West, we deliver both EFAW and FAW courses, along with Paediatric First Aid, Mental Health First Aid, and CPR and AED training. Our courses are designed to be hands-on, supportive, and tailored to the real-life challenges of working environments.

The Human Impact

Beyond the practical and legal aspects of the job, being a First Aider carries emotional responsibility. Helping someone in distress can be deeply rewarding—but it can also be stressful.

Employers should be aware of the potential impact of dealing with emergencies and ensure that First Aiders receive support if they’ve had to deal with particularly serious or upsetting incidents. This might include a debrief, access to mental health support, or simply time to recover and regroup.

Likewise, fellow employees should respect and support First Aiders—not just when things go wrong, but as an ongoing part of their workplace community.

Conclusion: A Critical Role in Every Workplace

The role of a First Aider at work is essential. It combines quick thinking, calm under pressure, and practical know-how with a strong sense of care and responsibility. First Aiders provide reassurance and action when it matters most—often before emergency services have even arrived.

For employers, having trained First Aiders is not only about legal compliance—it’s about demonstrating care for your people, reducing the risk of long-term harm, and creating a safer, more prepared workplace.

And for those who step into the role, it’s an opportunity to make a real difference. Whether responding to a simple cut or a life-threatening emergency, First Aiders are at the heart of workplace safety—and they deserve our training, trust, and full support.
