False Gas Leak Alarm Triggers Evacuation at UHasselt Diepenbeek
An evacuation of the UHasselt campus at Wetenschapspark in Diepenbeek was triggered by a false alarm, according to reports from HBVL, VRT, and De Morgen. The incident, initially reported as a potential gas leak or dangerous substance escape, was caused by a defective detection system and resulted in no actual gas leak.
Why was the UHasselt campus evacuated?
A defective detection system triggered the alarm, according to VRT. HBVL specifically attributed the evacuation to a defective smoke detector.
Emergency services responded to reports of a suspected gas leak. De Morgen reported that the event was later confirmed as a false alarm caused by a defective detector.
How did different reports characterize the incident?
News outlets varied in how they described the perceived threat during the event. TV Limburg reported the incident as a “deadly gas leak,” while De Standaard referred to it as a “possible dangerous gas escape.”
VRT described the situation as involving a “dangerous substance” on the campus. All outlets eventually confirmed that no gas had escaped and the alarm was false.
What happens next for the campus?
Campus administrators may evaluate the maintenance schedules for the detection systems to prevent future false triggers. The technical failure of the detector is likely to be reviewed to determine if a systemic replacement is necessary.

Emergency responders could use the experience as a benchmark for future responses. De Morgen noted the event was a “good exercise for emergency services,” suggesting the data gathered may be used to refine safety protocols.
