A standard Tuesday morning shift quickly turned into a worst-case scenario in the heart of Brussels. A sudden fire at the massive OXY building renovation project on Place de Brouckère has left multiple workers dead, several injured, and families waiting in agony.
At least 200 workers were on-site when the alarm sounded. While firefighters initially responded to what seemed like a minor, easily contained fire on the second floor, the situation rapidly spiraled. Flames slipped into the building’s elevator shafts, transforming them into vertical chimneys that funneled toxic smoke and intense heat directly through the core of the high-rise.
Rescue crews have made a grim discovery inside one of the stalled elevator cabins. We don't know the exact final toll yet, but the reality is devastating.
Why Elevator Shafts Become Death Traps in Construction Fires
When you look at modern high-rise renovations, the elevator shaft is often the most vulnerable structural point during a fire. It is essentially a giant chimney.
In a completed, operational building, strict fire-containment systems, pressurized shafts, and automatic fire doors prevent smoke from entering these vertical voids. But on a highly active construction site, these safety barriers are often disassembled, incomplete, or temporarily bypassed for worker access.
How the Chimney Effect Ran Out of Control at the OXY Site:
[Initial Fire: 2nd Floor]
│
▼ (Smoke & flames bypass incomplete seals)
[Elevator Shaft] ──► Acts as a vacuum, drawing heat upward rapidly
│
▼ (Stalls elevators, traps workers inside)
[Upper Floors / Underground Floors] ──► Secondary fire ignited below
According to Brecht Speybrouck, a spokesman for the local labor inspection service, rescue teams only managed to gain limited access to one of the two elevator cabins. Inside, they spotted the bodies of several victims. Because of heavy debris and extreme heat, recovering the victims and accessing the second shaft is taking hours of excruciatingly slow, dangerous work.
The Chaos on the Ground at Place de Brouckère
The OXY building, a prominent landmark formerly serving as administrative offices, was undergoing a massive, multi-year transformation. The plan by developers Whitewood and Immobel was to convert the massive concrete structure into a modern hub of apartments, hotel rooms, offices, and a rooftop bar.
Instead, the pedestrian zone surrounding the project is now a sea of emergency vehicles, police tape, and exhausted first responders.
- The Casualties: At least two people are confirmed dead, with local officials fearing the number will rise once the second elevator shaft is cleared.
- The Missing: Six construction workers remained unaccounted for hours after the initial evacuation.
- The Injured: Two workers were rushed to the hospital with severe burns, and a firefighter was treated for heatstroke after working in punishing conditions inside the core of the tower.
The political weight of the tragedy was evident by late afternoon. Belgium’s King Philippe and Prime Minister Bart De Wever arrived quietly at the cordoned-off site to show support, bypassing the cameras to let emergency teams do their work.
The Forgotten Safety Blindspot of High-Rise Renovations
Honestly, construction sites are significantly more dangerous than completed buildings when it comes to fire safety.
During a major renovation like the OXY project, you have a perfect storm of hazards. Hundreds of workers are performing hot work—welding, grinding, and cutting metal—surrounded by temporary wooden scaffolding, plastic sheeting, and flammable adhesives.
Even worse, the building's permanent fire suppression systems, like overhead sprinklers and fire-rated drywall partitions, are usually disconnected or not yet installed.
Once a fire breaks out, it doesn't just burn; it migrates. In this case, the flames shot through the vertical shafts and actually triggered a completely separate, secondary fire on an underground floor, boxing in rescue teams and cutting off escape routes.
What Needs to Happen Next on Active Sites
This tragedy should serve as a massive wake-up call for project managers and safety inspectors across Europe. You can't treat fire safety during a renovation as a secondary priority.
Immediate, practical changes are needed on active high-rise projects to ensure this doesn't happen again:
- Mandatory temporary shaft barriers: Elevator shafts under renovation must be sealed off with temporary, fire-resistant partitions at every floor to stop the "chimney effect" instantly.
- No elevator use during hot work: Workers should never rely on construction hoists or elevators located in active shafts while high-heat work is being conducted nearby.
- Zoned evacuation pathways: On-site safety leads must establish independent, pressurized stairwells that remain completely isolated from the main utility shafts of the building.
The Brussels public prosecutor’s office and labor inspectors are launching a full-scale investigation into the exact cause of the spark and why the evacuation plan failed to protect those trapped in the shafts. For now, construction has ground to a halt, and a city is left mourning a completely preventable loss of life.
