👉 Trichlorofluorocarbons (TFCs) are a group of chemical compounds that were used as refrigerants and solvents in the 1950s. They have been classified into two main groups based on their molecular structure, with one group containing trichloroethylene (TDI), while the other contains trichloroalkanes (TCAs). Trichlorofluorocarbons are highly toxic and can cause respiratory problems if inhaled
