When a fire alarm rings, we all know the golden rule. Avoid the elevator. Take the stairs. It is hammered into us from childhood. Yet, on a Tuesday morning in central Brussels, six people met a horrific end inside a lift shaft.
The disaster unfolded at the iconic OXY building on Place de Brouckère. What started as a seemingly minor second-floor fire quickly spiraled into a nightmare. It exposed a massive, lethal gap in construction site safety. Also making news recently: Why The Recent Chaos In Niger Capital Proves The Junta Is Losing Its Grip.
This was not an old, abandoned structure. The OXY building is a high-profile, multi-million-dollar renovation project. It was supposed to show off the future of green, circular architecture in Belgium. Instead, it became a tomb for six workers.
To understand how this happened, you have to look beyond the basic news reports. You have to look at how high-rise construction projects actually handle fire safety. Or, more accurately, how they fail to handle it. More details into this topic are covered by USA Today.
What Happened Inside the OXY Building
Around 8:00 AM on July 14, 2026, a small fire broke out on the second floor of the massive building complex. At the time, roughly 250 workers were scattered across the site. Under normal circumstances, a fire on the second floor of a concrete and steel structure is easily manageable. Firefighters arrived quickly and contained the initial flames within an hour.
But construction sites are not normal environments.
The flames found their way into the building's three open elevator shafts. Once inside, the fire did what fires in vertical shafts always do. It exploded upward.
A vertical shaft acts like a giant chimney. This is called the stack effect. The hot air and smoke rush upward at incredible speeds, pulling oxygen from below and feeding the flames. In the OXY building, the fire raced up the shafts, spreading smoke, heat, and toxic gases. It even jumped to the underground levels.
Trapped in one of the elevator cabs were the workers.
By the time the Brussels Fire Brigade spokesperson Walter Derieuw and local authorities could assess the damage, the tragedy was clear. Rescuers had to cut a small opening into the elevator cabinet. Inside, they found charred bodies. The rescue operations were painfully slow, hampered by unstable debris and intense heat.
The Danger of Renovating Yesterday's Giants
The OXY building is the reimagined Centre Monnaie, a towering 1970s cross-shaped monolith. It sits right in the beating heart of Brussels, perched on top of the busy De Brouckère metro station. The developer, a joint venture between Whitewood and Immobel, hired famed Norwegian architectural firm Snøhetta and Belgium’s Binst Architects to turn this aging concrete beast into a sustainable, mixed-use hub.
The plans were gorgeous. Apartments, a 250-room hotel, offices, a rooftop bar, and green suspended gardens. It aimed for the highest environmental credentials.
But renovating a 1970s high-rise is incredibly complex. It is far more dangerous than building a new one from scratch.
When you renovate, you are dealing with decades of old structural layouts. You are opening up walls, tearing out old fireproofing, and exposing elevator shafts that were designed under vastly different safety codes. The main contractor, Cordeel Group, was managing a sprawling, active job site with hundreds of subcontractors.
During active construction, a building's natural defense systems are asleep.
There are no active sprinkler systems. They are turned off to prevent accidental water damage or because the piping is being replaced. The fire doors that normally compartmentalize a building and stop smoke from moving floor to floor are often propped open or completely uninstalled. The elevator shafts, which should be sealed concrete channels, are open wounds in the middle of the structure.
If a spark hits a pile of building materials, there is nothing to stop the fire from traveling.
Why Were Workers in the Elevator Anyway
This is the big question everyone is asking. Why on earth were workers using an elevator during a fire?
On an active high-rise construction site, workers do not use the fancy, finished passenger elevators you see in completed office buildings. They use hoist lifts, which are often open-air metal cages attached to the outside of the building. Or they use temporary construction elevators installed inside the building's permanent shafts.
These temporary internal lifts are vital. Walking up and down twenty flights of stairs with heavy tools and materials ruins productivity and exhausts workers before they even start their shift.
But these systems are often manual or lack the advanced safety overrides of finished elevators.
In a finished building, modern elevators are integrated into the central fire alarm system. The moment a smoke detector trips, the elevators automatically descend to the ground floor, open their doors, and shut down. This is called Phase I Emergency Recall.
On a construction site, this integration does not exist yet.
The workers in that elevator likely had no idea a fire had started on the second floor. They got into the lift, pressed a button, and rode straight into a rising column of superheated gas and toxic smoke. Once the power grid failed or the lift mechanism warped from the heat, they were trapped in a metal box in a dark, burning shaft.
They did not stand a chance.
The Blind Spots in Construction Safety Standards
When we talk about workplace safety, we often focus on hard hats, harnesses, and scaffolding. We talk about preventing falls. Falls are, historically, the leading cause of death on construction sites.
Because of this, fire safety on active job sites is often treated as an afterthought.
Look at typical construction site fire prep. You will see a few portable fire extinguishers hanging on columns. You might see a temporary alarm system, which is usually just a series of battery-powered horns.
This is nowhere near enough for a high-rise.
A high-rise construction site needs to be treated like an active ship at sea. If a fire starts, you cannot just run out the front door. You are trapped hundreds of feet in the air.
We need to completely rethink how we protect workers in these environments.
Actionable Steps to Fix Construction Fire Safety
This tragedy cannot be dismissed as a freak accident. It was a failure of systems. If you run a construction site, manage a development, or work in building safety, you need to implement hard changes immediately.
Compartmentalize the Shafts
Never leave multiple elevator shafts completely open across all floors during a major renovation. Temporary fire curtains or draft stops must be installed at every opening. If a fire starts on one floor, these barriers prevent the shaft from turning into a chimney.
Mandate Temporary Fire Alarms in Lift Cabs
If workers are using internal elevators, those cabs must have direct, hardwired communication with the site’s temporary fire alarm system. If an alarm triggers anywhere in the building, the lift must automatically return to a safe exit floor, or at the very least, give an unmistakable auditory and visual warning to the occupants inside.
Establish Strict Hot Work Permits
Most construction fires are started by "hot work"—welding, cutting, grinding, or using open flames. These activities must require a written permit, a dedicated fire watch person who does not leave the area for at least 30 minutes after the work is done, and active fire extinguishing equipment on hand.
Conduct Real Evacuation Drills
Do not just hand workers a pamphlet on their first day. Run actual, unannounced evacuation drills. If you have 250 workers on site, you need to know exactly how long it takes for every single one of them to reach the muster point using only the temporary stairwells.
The Path Forward for High-Rise Development
The OXY project was designed to be a triumph of modern engineering. It was meant to show that we can take the gray, carbon-heavy concrete structures of the 1970s and breathe new, green life into them.
But sustainability means nothing if we cannot keep the people building it alive.
The investigation by the Brussels Labor Inspectorate and the local public prosecutor will eventually pinpoint the exact ignition source and the precise mechanical failures that trapped those six workers. They will look at whether Cordeel Group and the developers followed every local regulation.
But complying with the bare minimum of the law is clearly not enough.
We have to stop treating construction sites as temporary zones where safety standards can be relaxed. A half-finished building is the most volatile, dangerous environment in any city. It is time we started building, and renovating, like lives depend on it. Because they do.
