The askarels are used as insulating liquid and refrigerant in electrical transformers and other electrical appliances, because these synthetic liquids are very stable, corrosive name, low flammability and they are excellent thermal insulation agents.
It is an oil known under different commercial names:
* - PYRALENE: (France)
* - CLOFENE: (Germany)
* - PYRANOL: (Canada, United States of America)
* - FENCLOR: (Italy)
these insulating fluids based on polychlorobiphenyls (P.C.B) are extremely toxic products, if they predispose to the cancer of living cells, they become even more dangerous when subjected to intense heat in the presence of oxygen.
in fact when the temperature reaches 200 ° C, they are composed by giving rise to a hydrochloric gas. if their temperature is raised to 300 ° to 300 ° C., they give rise to highly toxic compounds
Polychloro - Dibenzo - Dioxin. the latter compound is none other than the: DIOXYNE
P.C.B can be absorbed by various forms of living being, and thus concentrates along the food chain; the fish first, then their predators and ultimately the man who consume each other.
IN CASE OF FIRE:
Insulating fluids based on P.C.B, evaporate and are found in the atmosphere,
Wind then can scatter them, and rain or snow will make it fall to the ground.
