Routes of exposure The substance can be absorbed into the body by inhalation.
Effects of short-term exposure The substance is corrosive to the eyes, skin and respiratory tract. The liquid may cause frostbite. Inhalation of this gas may cause lung oedema. See Notes.
Inhalation risk A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
Effects of long-term or repeated exposure The substance may have effects on the bones and teeth. This may result in fluorosis.
OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.1 ppm as TWA
The occupational exposure limit value should not be exceeded during any part of the working exposure. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
