[Concerning the casuistics by aspiration of waste oil sediments (author's transl)].

When cleaning an underground waste oil dump, an 18 year old worker suffered loss of consciousness by inhaling vapours of trichloroethylene and then suffocated by aspiration of waste oil sediments. Histological examination of the lungs proved the copious presence of partly granulous darkish-brown and of rather light coloured crystalloid foreign substances up to the multiple size of erythrocytes. "Chemical examination of blood, brain and urine showed the presence of trichloroethylene and its metabolites, respectively. The trichloroethylene concentration has been determined in the brain."
