Safety

Vinyl fluoride is classified as an IARC Group 2A carcinogen (likely to cause

cancer Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal b ...
