Is hydrofluoric acid hazardous?

Hazard Summary Hydrofluoric acid (HF) and Hydrogen Fluoride (HF) are very poisonous, highly irritating and corrosive. Hydrofluoric acid or Hydrogen Fluoride (HF) is fatal if inhaled, if swallowed, or in contact with skin. It causes severe skin burns and eye damage. The effects may be delayed after exposure.

What is the antidote for hydrofluoric acid?

ANTIDOTE: There is no antidote for hydrofluoric acid (HF) toxicity. Calcium- or magnesium-containing antacids (which bind fluoride ion) have been suggested for use in the treatment of ingestion exposure. Quaternary ammonium compounds or calcium-containing gels may be used topically in the treatment of skin burns.

Is HF flammable?

Hydrogen fluoride is non-combustible, but may create irritating and corrosive fumes of fluorides when heated or in combination with steam or water. Since hydrogen fluoride does not burn, use an extinguishing agent suitable for surrounding fire.

What is the antidote for fluoride?

Boron as an Antidote to Fluoride Toxicity : Epidemiology.

What is HF name?

HYDROFLUORIC ACID. Hydrogen fluoride. 7664-39-3.

Why is HF stored in plastic?

Because of the high reactivity toward glass and moderate reactivity toward many metals, hydrofluoric acid is usually stored in plastic containers (although PTFE is slightly permeable to it).

How much hydrofluoric acid is in fluorocarbon?

/Hydrofluoric acid/ 65% was used in fluorocarbons; 10% in fluorides & other chemicals; 8% in aqueous solutions (100% Hydrogen Fluoride Basis); 5% in aluminum fluoride (merchant); 5% in petroleum alkylation; 4% in nuclear applications ( uranium ); and 3% in miscellaneous use (1984). /Hydrofluoric acid/

What is the UN code for hydrofluoric acid?

What is the active ingredient in hydrofluoric acid?

The Active ingredient is Hydrofluoric Acid. Hydrogen fluoride, anhydrous appears as a colorless fuming liquid boiling at 67°F. Shipped as a liquid confined under its own vapor pressure.

When is hydrofluoric acid a hazardous waste?

U134; As stipulated in 40 CFR 261.33, when hydrofluoric acid, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations.
