At 9 am, in a plastic packaging factory, the extrusion workshop staff detected a strong smell of solvent coming from the print workshop. A pipe of ethyl acetate supplying a printing machine was leaking into a 200-m² workshop; 4,000 litres of product were spilled with 3,000 litres into the company refuse disposal unit. Power supply was cut and 12 employees were evacuated, with one being slightly overcome by the fumes. The general supply valves for the solvent outside the workshop were closed, and the doors and windows of the workshop were then opened to ventilate it. Fire-fighters using self-breathing apparatuses located the leak and carried out explosimeter measurements in the workshop and the wastewater system; these measurements turned out to be negative. There was no risk to the surrounding population and the fire department authorised the resumption of a neighbouring workshop (extrusion and bagging). The emergency services and workshop foreman entered the premises and found that the ethyl acetate supply valve on the printing machine was open. The fire-fighters, aided by the workers involved, recovered 2,200 litres of solvent. The operator estimated that 800 litres had evaporated into the atmosphere. The solubility of the product eliminated the risk of explosion and the product that flowed in the retention basin was pumped with explosion-proof equipment. The intervention ended at around 2 pm; six employees were made redundant. A plant technician left the acetate supply valve open and the supply pump remained blocked. The worker had not noticed any fault when leaving his post on 25th November at 5:30 am, and the specific pump blocked later. No spillage of the substance into the networks was observed, as the solvent was diffused into the atmosphere.

The Classified Facilities Inspectorate carried out a site inspection on 27th November. The operator was requested to conduct a fire safety audit of the entire site, provide the safety zone plans, install the monitoring system and requisite sensors, furnish and implement operating and safety instructions, and establish an emergency plan in accordance with current regulations. The operator was also bound to construct retention tanks for the storage, retention basins associated with the unloading dock for hazardous materials, install any equipment ensuring safety with a backup power supply, and take all necessary and sufficient measures in terms of organisation and surveillance to prevent the incident from recurring. The Inspectorate recommended that the Prefect issue a formal notice.
