In an inactive poultry meat manufacturing plant, fire broke out on a Sunday at 8 am in a refrigerated building made of sandwich panels. Emergency services were alerted at 8:17 am and faced the violent incident 11 minutes later.

They were unable to enter the building since no staff were working, so these fire-fighters protected the neighbouring installations and alerted the gas and electricity services. The fire was brought under control at around 11 am. Surveillance patrols were put into place for the night.

The fire destroyed 1,200 m² of buildings. No details were provided about potential damage to the cooling system. About 20 employees and 12 temporary workers had their work contracts suspended.

The police concluded that the fire was accidental. An expert appointed as part of a civil suit noted that employees had left the facility 2 days earlier at 5 pm, with a cleaning company entering the premises afterwards. A plant manager performed a routine inspection at 7:30 am the day before the incident, and at the same time on the day of the incident without any noticeable anomaly.

The expert stated that the fire had started in the onsite packing room and spread beneath the factory roof. According to this expert, the heat welding bars of a bagger were kept at the same temperature 24 hours a day to avoid condensation problems detrimental to production, but the control system, with well-documented malfunctions, was the cause of this accident. The bagger was covered with a tarpaulin protection to allow the workshop to be cleaned. The plastic film used to make the bags appeared to have fallen by gravity, getting blocked next to the heat welding bars; exposed to thermal radiation, this film gradually heated until pyrolysis occurred. The gases generated gradually filled the enclosed volume formed by the tarpaulin, and the air / flammable pyrolysis gas mixture ignited a few hours later. The fire then spread to the plastic film and facility installations.
