Risque explosif par mélange de produits chlorés destinés à l'entretien de piscines individuelles : à propos d'un cas

Trichloroisocyanuric acid and calcium hypochlorite are chlorine-derived substances that are commonly used to disinfect swimming pools. When these substances are mixed together, a chemical explosion can occur. We report the case of a 46-year-old man who sustained injuries as a result of mixing trichloroisocyanuric acid and calcium hypochlorite. He had a superficial punctuate keratitis, a limbic ischemia, and was burnt on 8% of the total body surface. He was hospitalized for seven days, and the clinical course was favorable. At follow-up one month later, the patient had no pulmonary, dermatological or ocular sequelae. This case illustrates the dangerous mixing of two substances that are readily available to the public. The current increase in the market for private swimming pools may promote the risk of such accidents. Health professionals must report these cases to poison control centers for alerts in toxicovigilance to be triggered at the national level.
