Results of tests carried out at Collège Charles III


Following the incident at Collège Charles III on Wednesday 7 February and the symptoms reported by various students on Thursday 8 February, the Government decided to temporarily close the school as a precaution. On Friday morning, a series of additional analyses and tests were carried out to explore all possible hypotheses and rule out any risk.

These measures were taken by a Nuclear, Radiological, Bacteriological and Chemical detection, identification and sampling vehicle from the Marseille Naval Fire Battalion, as well as by independent technicians at the SOCOTEC certified inspections office.

These in-depth investigations and measures were carried out according to standard protocols, in the main areas of Collège Charles III, including the pool maintenance room, the site of the 7 February incident, various classrooms, the infirmary and the refectory.

Air samples and measurements looked for the possible presence of different pollutants such as carbon monoxide (CO), hydrogen sulphide (H2S), chlorine (CL2), nitrogen trichloride, trihalomethanes, phosphorus, arsenic and sulphur. The consistent results obtained by both the Marseille Naval Fire Battalion and by the SOCOTEC certified inspections office unequivocally confirm the absence of toxic substances in the air inside the establishment.

Based on these results, the Prince's Government has confirmed the re-opening of Collège Charles III and the resumption of classes on Monday morning, 12 February.
