What did the two CRS companies in Sancerre and Charleville-Mézières inhale to feel such symptoms almost instantly? Tuesday, June 16, these officials were responsible for ensuring the security of the demonstration of caregivers in Paris - during which overflows were observed - when they wiped the jet of a glass object which, by breaking on the ground, released thick white smoke and paint-like droplets. A few seconds later, the police felt skin and eye irritation, difficulty breathing, burning sensation and nausea.
In a note that 20 Minutes was able to consult, the central laboratory of the Paris police prefecture hypothesized that these "incapacitating symptoms" could have been triggered by the inhalation of titanium tetrachloride (TiCl4). Researchers describe a characteristic chemical reaction of this substance. "During use, the TiCl4 bulb breaks, the liquid spills and immediately turns into contact with air into titanium dioxide, which is a white powder, and into a cloud of acid droplets hydrochloric ", specifies the laboratory. In order to confirm this hypothesis, a sample was taken from the shield of a CRS itself victim of these symptoms.
Titanium tetrachloride was once used in the production of tear gas before being abandoned due to the toxicity of smoke. "This type of device is no longer used by the police, but it is sometimes found in recycling centers or in certain cellars," said the note. On June 16, the police headquarters had reported 32 arrests related to the scuffles and 19 wounded in the ranks of the police.
