A major fire destroyed 15,000 m² of one of the buildings at the Le Bourget Exhibition Centre. The building was housing party fixtures on exhibit. Small quantities of recreational fireworks were also on hand: firecrackers, rockets, birthday candles. The roof collapsed. The gas bottles used to fuel the hall’s forklifts exploded. During their battle against the blaze, 150 fire-fighters experienced problems related to water supply and were forced to connect to distribution pipes from the neighbouring city. 16 fire nozzles proved necessary. One fire-fighter was slightly injured during the emergency response. A national highway and a portion of the local motorway were closed to traffic to allow running the pipes. The accident was brought under control within 3 hours. Among the initial hypotheses of potential causes, a faulty electrical installation was cited. The presence of fireworks, if confirmed, would have provided another potential cause.
