Ethanol spill caused Tomorrowland stage fire, postponing Brasil event
A subcontractor's ethanol spill during pyrotechnic testing destroyed the Tomorrowland Mainstage, forcing the Belgian festival to rely on borrowed equipment and delaying its South American expansion.
An accidental ethanol spill during pyrotechnic testing caused the fire that destroyed Tomorrowland’s Mainstage last year, according to a report citing sources close to the ongoing investigation. The leak of the highly flammable substance occurred while subcontractors were testing fire bowls just 48 hours before the Belgian festival was due to open, highlighting the fragile logistics behind Europe's largest summer events.
Emergency services extinguished the blaze without injuries, but the destruction of the Orbyz Mainstage forced a major operational scramble. Workers installed a smaller replacement stage to keep the event on schedule, relying in part on stage parts temporarily loaned by Metallica from the band's recent European tour. This unprecedented pivot demonstrated the informal networks artists and organisers use to keep major tours and festivals running.
The destruction had immediate consequences for the international expansion plans of WEAREONE.world, Tomorrowland’s parent company. The custom-built stage was slated for direct reuse at Tomorrowland Brasil, a key market for the brand's growth. With the structure reduced to ash, organisers were forced to postpone the 2026 edition of the South American event entirely.
The near-miss prompted scrutiny from local government stakeholders, who commissioned an independent safety assessment alongside the municipalities of Boom and Rumst and the Governor of the Province of Antwerp. The review cleared this year’s event to proceed, with the festival returning to Boom this weekend and a second weekend following on 24th July. Crucially for organisers, it concluded that attendees would have reached safe areas within required timeframes had the stage been occupied when the fire broke out.
Spokesperson Debby Wilmsen acknowledged the incident but defended the company's existing protocols. "The fire will always remain a part of Tomorrowland’s history. We are very aware of that," she said. "Of course, we never want to experience anything like this again, but the risk analysis also confirmed that our safety procedures were already very well organised."
Wilmsen noted that the company continuously evaluates operations but accepted that absolute risk elimination is impossible for large-scale live events. "It is impossible to eliminate every risk entirely," she said. "Weather conditions and human behaviour are factors that no one can fully control."
