These principles serve as a foundation for every action taken in emergencies, helping a first aider stay calm and focused.
In this blog, we will break down each of these three duties and why they’re so important. Let’s get started.
Who is a first aider?

A first aider is a trained person who can give medical assistance in case of an emergency to the casualty. When someone is ill or injured, a first aider assesses the situation before starting the treatment.
Accidents can occur anytime and anywhere, and professional medical help isn’t always immediately available. In moments like these, a first aider is often the very first responder to step in and take control.
A trained first aider can manage an emergency and deliver vital support that can save lives. Their duty isn’t just confined to giving medical care, but also to reassure the casualty and make them feel safe. This small act has a significant impact on the casualty.

What Are The 3 Primary Duties Of A First Aider?

The three primary duties of a first aider provide structural guidance to a first aider to handle emergency situations. These three primary duties are often known as the 3 P’s of first aid, which are:
- Preserve life
- Prevent deterioration
- Promote recovery
Let’s take a look at how these primary duties help a first aider to mitigate injury:
Preserve life
Preserving life is the first priority. No matter what, keeping the casualty alive until professional medical help arrives is your main goal as a first aider. When you arrive at the scene, make sure that the area is safe for you.
So, what is the best way to preserve life? The most appropriate approach is to stick to the CAB (Circulation, Airway, Breathing) standard. Under this protocol, you will begin by ensuring that the blood flow is normal and that the airway is clear and that the casualty is getting air.
Prevent deterioration
Preventing deterioration in first aid means you have to stop the patient’s condition from getting worse. If the casualty is already in a bad condition, you have to ensure that they stay stable.
You can prevent deterioration by stopping the bleeding of the casualty by applying pressure to the wound. Some other ways to prevent deterioration are to immobilise broken bones, prevent infection in wounds, and keep the patient comfortable.
Promote recovery
So after you have preserved the life and stabilised the patient’s condition, it’s time to work on the recovery from the injury. This means working to make the patient’s condition better.
In this stage, you have to work on the pain relief of the patient. You can start by putting the injured or ill person in the recovery position. They remain calm with the aid of small gestures, like speaking in soft tones, holding their hand, and maintaining eye contact.
The importance of 3 P’s in first aid
As mentioned earlier, the three primary duties of a first aider are known as the 3 P’s of first aid. These are not just principles, these are a structured guide to help a first aider respond confidently in emergencies.
In case of any emergency situation, quick yet careful decision making is needed. So working in a structured way helps you to focus and avoid panic. When treating an injured person, acting quickly and accurately is key. That’s where the 3 P’s of first aid help you to provide the proper treatment.
Handling an emergency situation needs calm and focused thinking. The 3 P’s of first aid are designed to keep things simple so that you can easily fulfil your primary duties.
How to be a qualified first aider?
Just knowing the right techniques doesn’t make you a qualified first aider. Staying calm, confident and ready to act in an emergency situation is also essential. Every situation is different, but the qualified first aiders follow some effective methods that help them make the right decisions under pressure.
In any emergency or accident scene, first assess the situation. The initial assessment will give you a rough idea about what measures can be taken. If you see that first aid won’t be enough, then the casualty must be hospitalised immediately. If not, you may proceed with your treatment.
Qualified first aiders always start providing care by following the 3 P’s of first aid: preserve life, prevent deterioration, and promote recovery. Proper communication with the casualty eases the situation for them. It may not be much, but the way you speak to an injured person can help reduce pain.
Practice and preparation are also important to become a qualified first aider. Completing a first aid training is the best way to prepare yourself. The industry standard is to regularly refresh your knowledge and familiarise yourself with first aid kits and workplace procedures.
