Useful:

• Chemical Classes: Toxic Gases & Vapors -> Acids, Inorganic
• Canonical SMILES: F
• Inhalation Risk: A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
• Effects of Short Term Exposure: The substance is very corrosive to the eyes, skin and respiratory tract. Inhalation of the gas or vapour may cause lung oedema. Inhalation may cause asthma-like reactions (RADS). Exposure could cause asphyxiation due to swelling in the throat. Inhalation may cause pneumonitis. Exposure could cause hypocalcemia. The effects may be delayed. Exposure above the OEL could cause death.
• Effects of Long Term Exposure: Fluoride can accumulate in teeth, joints and bones. This may result in stained tooth enamel up to joint and bone disorders (fluorosis).
