🩹First Aid Principles

Assessing scene safety before approaching

Before you approach an injured person, pause for ten seconds and ask: is it safe for me to approach this scene right now?

The natural instinct when you see someone injured or fallen is to rush straight to them. That instinct is entirely human and nothing to be ashamed of, but it needs one moment of pause before acting. The first principle every professional responder learns on their first day of training is this: an unsafe scene does not absorb an additional rescuer — it absorbs an additional casualty. An emergency team that arrives to find a volunteer injured alongside the original casualty now has two problems with the same resources. Before you take a single step toward the injured person, stop for a moment and look: what happened to this person? And is whatever happened to them still present and able to happen to you?

Assessing scene safety does not mean hesitating or standing idle — it means a quick scan in ten seconds. Look around you in order: is the ground stable or is there a risk of collapse or slipping? Is there smoke or a strange smell indicating gas or chemicals? Is there a vehicle still moving or traffic that has not stopped? Is there visible electrical danger or exposed cables on the ground? Is the security situation around the incident stable? These five questions take ten seconds and protect you from sliding from a capable witness into a second casualty who adds to the emergency burden.

• Active fire or thick smoke: do not enter a burning building or vehicle — smoke alone causes loss of consciousness within seconds
• Exposed electricity: do not approach anyone touching a live cable or damaged pole — electricity travels through the ground over a wide radius
• Traffic accidents: confirm that vehicles have stopped before entering the road — most secondary casualties arrive trying to help the first
• Collapse or structural failure: do not stand beneath a leaning wall or near a structure that may continue to fall
• Chemical or unknown spills: if you smell something strange or see liquids of an unusual colour, move away and tell the emergency services
• Active violence: if there is an ongoing fight or clear physical threat, do not intervene physically — your safety is a condition for helping anyone else

How to call for emergency help

An organised call that takes thirty seconds is worth far more than a panicked one that takes three minutes and never gives the location.

Many people call the emergency services in a state of panic and begin by shouting or describing the incident in exhausting detail without saying where they are. Emergency call handlers are trained to stay calm and help you provide information — but the information that gets lost in the chaos is always the location, and it is the only piece of information nobody can guess. If the call drops after a few seconds — and this happens — an ambulance can move if it knows where to go, and it can do nothing if it only knows what happened. For that reason alone, location is the first thing you say and the most important.

1. Exactly where you are: the full address or nearest intersection, the nearest prominent landmark such as a mosque, school, or petrol station, and the floor if you are in a building
2. What happened in one sentence: someone fell on the stairs, a road collision, a man unconscious on the pavement, a woman complaining of chest pain
3. How many are injured and roughly what age: one person, a man of about fifty
4. The casualty's current condition: are they conscious and responding? Are they breathing? Is there visible bleeding? Can they speak?
5. Your phone number — and do not end the call before the handler explicitly tells you to

In a group working together, one of the worst things that can happen is for everyone to assume someone else has called the emergency services. This is not necessarily negligence — it is the natural result of unclear role allocation in a moment of pressure. Avoid it with one clear sentence: say a specific person's name out loud and audibly for everyone: "Mohammed, you call the emergency services now while I stay here." A specific name, a specific task, and a specific time — these three eliminate all ambiguity.

Staying with the casualty until the paramedic arrives

The minutes between calling the emergency services and the paramedic arriving are not waiting time — they are real, impactful presence.

Being beside an injured person and speaking to them calmly is itself a real act of help with genuine medical value. A conscious person who is in pain or frightened needs to hear a voice telling them they are not alone and that help is coming. Panic accelerates the heartbeat, raises blood pressure, and worsens many conditions — and a calm voice beside them measurably reduces that panic. Say clearly and calmly: "I am here. Help is on the way. Do not move." Those three sentences do multiple things at once: they reassure, they prevent the person trying to get up alone which might add injury to injury, and they tell them that someone is watching and has the situation in hand.

When the paramedic arrives, give them the information in two or three clear, concise sentences: "She fell on the stairs fifteen minutes ago, lost consciousness briefly then came back, I have not moved her or given her anything." This precise information saves the paramedic valuable assessment time. And if asked to step aside, do so immediately without hesitation — the paramedic needs space and calm to carry out their rapid assessment, and stepping back is not dismissal but another form of real help.

What you must not do

Every prohibition in this module has a specific medical reason — knowing the reason makes compliance far easier than memorising the list.

The human instinct when facing pain and danger is to act. That instinct deserves to be honoured — but it needs precise guidance. In first aid, the wrong action is sometimes worse than doing nothing at all. The oldest medical principle taught in medical schools and training programmes worldwide — "first, do no harm" — is not said to patients but to those who treat and intervene around them. It applies to everyone who steps into an emergency: the professional paramedic, the doctor, and the volunteer who is trying to help with good intentions but insufficient training. Good intentions do not cancel harmful outcomes.

Every item on the "do not" list has a specific medical reason worth understanding. Pulling out an embedded object is forbidden because it is often what is pressing on blood vessels and limiting bleeding — removing it may release an acute internal haemorrhage. Giving water to an unconscious or semi-conscious person is forbidden because the fluid may reach the lungs and cause choking. Removing a helmet without specialised stabilisation equipment may convert a stable neck injury into paralysis. Pressing on an eye wound may drive the foreign object deeper and damage the retina. Entering a burning building converts you from someone able to call for help and direct paramedics into someone who needs it themselves. You do not need to memorise all these details — it is enough to remember the overarching rule: if you are not completely certain what you are doing and what its effect is, do not intervene.

Why this course is not a substitute for certified hands-on training

The difference between this course and certified training is not in the information — it is in the hands, the body, and the repetition.

Most core first aid skills are physical skills that cannot be learned by reading alone. CPR requires pressing with a specific force, depth, and rhythm — one hundred and twenty compressions per minute — on a real chest or a purpose-built manikin. Opening an airway requires a precise angle of the head that differs between adults, children, and infants. Pressing on a severe bleed requires force, steadiness, and an exact location. The Heimlich manoeuvre requires finding the correct pressure point and applying the right force without breaking ribs. These things are not learned by reading their description — they are learned through repeated physical practice with a qualified instructor who corrects pressure, angle, and timing in real time.

There is a wide, documented gap in psychology and learning science between "I know what I should do" and "I can do it correctly right now under the pressure of a real situation." Motor skills — as scientists call them — require the body to have gone through the movement tens or even hundreds of times before it can perform them automatically and correctly when there is no time to think. In CPR specifically, studies show that even trained people begin to see quality decline within weeks of their last training session. This is why professional paramedics renew their certifications every two years in most countries. This course gives you something real and valuable that should not be underestimated: understanding what is happening in an emergency, knowing your role and its limits, and making correct decisions in the first seconds. But certified hands-on training is what gives you the actual skill to carry out the procedures.
