Fluorine organic chemistry
WebFluorine gas is corrosive to all exposed tissues including upper and lower respiratory tracts., eyes, nose, and any other exposed mucous membranes. Fluorine penetrates deeply into body tissues and will continue to exert toxic effects unless neutralized. Workers should have 2.5% calcium gluconate gel on hand before work with fluorine begins.
