Four Limburg metalworkers killed in fire at Brussels Oxy building
Four employees of the same Limburg metalworking company died in a fire at the Oxy building in Brussels. Belgian media, including Het Nieuwsblad and HLN, identified them as Stijn (46), Koen (44), Johan (36) and Jille (23). Prosecutors and fire investigators are working to establish how the blaze started and why the men could not escape.
Four people went to work and did not come home, and they all worked for the same employer — a loss that lands on one Limburg company, one workforce and one set of families at once. For anyone working on Belgian building sites, whether as staff or as an external contractor, the case goes to a question that recurs in Belgian workplace-safety files: who is responsible for the safety of people working inside a building they do not occupy or control.
The Oxy building is a property in Brussels where a fire broke out, killing four workers. The four men were employees of a metalworking company based in the province of Limburg, in Flanders, who were working on site at the time. Belgian media — Het Nieuwsblad (Mediahuis) and Het Laatste Nieuws (DPG Media) — identified them by first name and age as Stijn (46), Koen (44), Johan (36) and Jille (23). Investigations into fatal fires in Brussels are led by the Brussels public prosecutor's office, working with the Brussels fire brigade (DBDMH/SIAMU) and, in workplace deaths, the federal labour inspectorate's welfare-at-work directorate.
Background
Fatal fires and workplace deaths involving external contractors have repeatedly prompted scrutiny of Belgium's shared-responsibility rules, under which a client company and a contractor both carry duties for the safety of workers on site. Belgium's welfare-at-work legislation requires coordination between the two, and fatal incidents involving contracted workers are routinely examined by the federal labour inspectorate alongside the criminal investigation. Brussels, with a dense stock of older office buildings undergoing renovation, has seen recurring debate over fire safety during works, when detection and evacuation systems are often partly disabled.
What to do
For contractors working on Belgian sites, the case is a reminder to confirm before work begins who holds responsibility for fire detection and evacuation on a site that is under renovation, and to insist on a documented site briefing covering escape routes. Workers have the right to refuse work they judge to present serious and immediate danger under Belgian welfare-at-work rules.
Impact
Regional — The four men worked for a metalworking company based in Limburg, and the deaths are being felt most acutely there — in the firm's workforce, in the municipalities the men came from, and among the network of subcontractors that Limburg's metal sector supplies across the country. Het Nieuwsblad reported the story through its Limburg regional desk, reflecting how directly the province is affected.
Opposing perspectives
- Employers' federations and contracting firms
Sector bodies representing Belgian metal and construction employers, including Agoria and Embuild, consistently argue that safety on multi-employer sites depends on clear coordination agreements rather than additional layers of regulation, and that responsibility must be traceable to whoever controls the specific work being carried out. In their reading, the existing welfare-at-work framework already assigns duties adequately; the failures that produce fatalities are failures of execution and communication on the day, not gaps in the law.
- Trade unions ABVV/FGTB and ACV/CSC
Belgium's main trade union confederations have long argued that subcontracted and temporary workers face systematically higher risk because responsibility is dispersed across client, contractor and staffing chains, and that the federal labour inspectorate is under-resourced to police it. They typically call for stricter enforcement, heavier sanctions where coordination duties are breached, and stronger rights for workers to refuse unsafe conditions on sites they do not control.
- Brussels fire-safety and building authorities
Brussels fire-prevention services and regional building authorities frame incidents in renovation contexts around detection and evacuation systems that are frequently deactivated or incomplete while works are under way. Their position is that permit conditions and temporary fire-safety measures during works need enforcement on site, not only on paper, and that responsibility for maintaining escape routes during construction rests with the building's operator as much as with any contractor.
