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.
通过四氟化碳纤维（CTF）生产的中试工厂进行了卫生学研究。研究证明，该生产过程的主要危害是CTF粉尘和氟化氢。工作场所空气中CTF粉尘的平均轮班浓度为0.6 - 1.5毫克/立方米，除反应室之外，在所有工艺场所均比HF的最高容许浓度高出2倍。该工厂的工人尿氟排泄量较高，主要是由于摄入了HF。实验研究表明，CTF的细胞毒性和致纤维化活性较低，这些化学品被归为IV级危险类别（轻度危害）。如果CTF接触皮肤，会被吸收并引起轻微的局部刺激。工作场所空气中CTF的最高容许浓度设定为6毫克/立方米。
