Hydrogen Fluoride – HF

This page hydrogen fluoride  – or hydrofluoric acid  – ( HF ), suitable detection tools – Hydrogen fluoride gas detector – and respiratory protective equipment (gas mask or E-P3 with combined filter  provides information about powered air purifying respirator).

Hydrogen fluoride (HF) properties

Hydrogen fluoride ( HF ) – hydrofluoric acid Also known as – can exist in gaseous or liquid form at ambient temperature. Mainly in the petrochemical industry alkylation catalyst , but is also used in the pharmaceutical industry (synthesis of pharmaceutical products), on construction sites (building facade cleaning) and in surface treatments (pickling) or uranium treatment.

Health effects of hydrogen fluoride

Hydrogen fluoride ( HF ), sharp It is a colorless gas with an odor. This gas when inhaled (R26), very toxic if swallowed (R28) or in contact with skin (R27). It reacts with water to form hydrofluoric acid; which is very corrosive and extremely dangerous for the environment; It changes the pH of the water. Even though this gas is not flammable, it reacts with almost any metal in the presence of moisture and produces hydrogen (H2); This is an extremely flammable gas.

Hydrogen fluoride gas detector – HF

Hydrogen fluoride can be detected by smell, but only one The HF gas detector can accurately measure concentrations of this highly toxic gas. A fixed or portable ppm detecting hydrogen fluoride gas It is recommended to use the system.

HF respiratory protection – Hydrogen fluoride

Full face mask for short interventions as hydrogen fluoride is irritating to the eyes or With E-P3 combined filter fully equipped powered air breathing apparatus It is recommended to use . If concentrations exceed 60 times the OEL, a self-contained breathing apparatus (SCBA) is required.
