A scaffolder falls through a fragile skylight. His crew stands over him, unsure whether to move him, roll him, or run. That moment of paralysis costs people their lives. It does not have to.

The incident circulated widely because the footage was dramatic. The real story is what happened in the seconds after. Construction sites are full of people who know how to build things and have no idea what to do when a colleague stops responding. That gap is not a character flaw. It is a training failure.

Head injuries are the leading cause of fatal trauma in construction. Falls from height account for the majority of construction deaths in Ireland every year. When the casualty hits the ground, the primary injury is already done. What happens in the next five minutes determines whether they survive it.

What Unconsciousness Actually Tells You

Unconsciousness means the brain is not managing the body normally. It can signal a bleed inside the skull, a severe concussion, spinal cord involvement, or a combination of all three. You cannot tell from looking at someone which of these is happening. Neither can the paramedics until they scan.

This matters because it changes what you do. An unconscious person is not simply asleep. They have lost their airway protective reflexes. Left on their back, they can drown in their own vomit. The tongue can fall back and block the airway completely. Both of these kill people who survived the initial fall.

Your job in the first minutes is not diagnosis. It is keeping an airway open and keeping them alive until the ambulance arrives.

The First Thing You Do

Check the scene. If the roof or structure is unstable, you are no help to anyone if you go through it too. Get eyes on before you commit.

Call 999 or 112 immediately. Do not delegate this to whoever looks most anxious. Point at a specific person and tell them to call and report back to you. Vague instructions in a panic produce nobody calling.

Then assess the casualty using a simple sequence.

Check for response. Shout their name. Squeeze their shoulders firmly. No response means they are unconscious.

Open the airway. Tilt the head back gently and lift the chin. Look, listen, and feel for breathing. Give it ten seconds.

If they are breathing, move to the recovery position. If they are not breathing and there is no pulse, start CPR.

The Recovery Position: Get It Right

The recovery position keeps the airway open and lets fluid drain away from the throat. Done correctly, it saves lives. Done wrong on a casualty with a spinal injury, it can worsen damage.

Here is the tension. You cannot always know if there is a spinal injury. In a fall from height, assume there is. But if an unconscious casualty is not breathing because their airway is blocked, a blocked airway kills them faster than moving them.

Airway takes priority. Always.

If they are breathing and you have no reason to suspect a spinal injury, the standard recovery position works. Kneel beside them. Place the arm nearest you out at a right angle, elbow bent, palm facing up. Bring their far hand to their near cheek and hold it there. Pull the far knee up so the foot is flat. Roll them toward you onto their side using the knee as a lever. Tilt the head back slightly to keep the airway open. Check breathing regularly.

If you suspect a spinal injury, do not move them unless the airway is completely blocked and you cannot clear it any other way. Keep their head and neck in a neutral position. If you have to roll them, try to keep the spine aligned throughout, ideally with a second person stabilising the head.

This is where first aid training for construction teams becomes non-negotiable. Reading about it is not the same as doing it with your hands.

When You Must Not Move Them

Three situations where movement without spinal precautions is wrong unless the alternative is immediate death.

Falls from more than two metres. A skylight fall almost always qualifies. The forces involved are enough to fracture vertebrae without obvious external signs.

Head first or face down impact. The mechanism alone tells you the cervical spine was loaded.

Helmet with visible impact damage, or helmet that came off during the fall. The helmet absorbed energy the spine may also have absorbed.

In all three cases, your default is: do not move, maintain airway, monitor breathing, wait for emergency services. If the casualty vomits and you need to turn them, log roll with the spine in alignment and do it as a coordinated team movement.

The Bits People Get Wrong

People shake an unconscious casualty repeatedly, trying to rouse them. Stop. One firm stimulus is enough to assess response. Repeated shaking risks aggravating spinal injury.

People leave an unconscious casualty on their back while they run to get help. An unconscious person left supine can die from airway obstruction in under two minutes. Position the airway first, then go.

People remove helmets immediately. Unless the helmet is actively restricting breathing, leave it on. Removal risks movement of a potentially unstable cervical spine.

People crowd around. One person manages the airway and directs. Everyone else steps back, keeps the area clear, and directs the ambulance crew to the exact location. Construction sites are not easy to navigate in an emergency.

What the Site Needs Before the Incident

Every Irish construction site with more than five workers is legally required to have an occupational first aider on site. Not someone who did a two-hour online course. A trained occupational first aider.

Check your emergency action plan covers exactly this scenario. A worker goes unconscious after a fall from height. Who calls? Who manages the casualty? Who meets the ambulance? Who secures the area? If the answers involve whoever happens to be nearby, the plan is not a plan.

Construction falls keep happening in part because prevention gets more attention than response. Both matter. You can do everything right on prevention and still face a day when someone goes through a roof.

The scaffolder in that footage survived. Not every casualty does. The difference between a survival outcome and a fatal one often comes down to what the first person on scene did in the first ninety seconds.

Know the recovery position. Know when not to move. Know your site emergency plan before you need it.
