    Abstract:
    Hygienic studies were conducted by means of pilot industrial plant for production of carbon tetrafluoride fibers (CTF). The studies proved that the main hazards of the production are CTF dust and hydrogen fluoride. Average shift concentrations of CTF dust in tne air of workplace equal 0.6-1.5 mg/cu m which 2 times higher than the MAC for HF at all technologic sites except for reactor compartment. The workers servicing the plant demonstrate higher urinary fluor excretion mostly due to HF intake. Experimental studies showed that CTF have low cytotoxicity and fibrogenic activity, these chemicals are assigned to IV jeopardy class (mild hazards). If applied on skin, CTF are absorbed and induce slight local irritation. The MAC for CTF in the air of workplace is set at 6 mg/cu m.
