Hydrogen fluoride – HF

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

Hydrogen fluoride gas detector, sensors and HF respiratory protection for better safety

Hydrogen fluoride properties

Hydrogen fluoride (HF) – also known as hydrofluoric acid – can be found in its gaseous form or under its liquid state at ambient temperature. It is mainly used in the petrochemical industry as an alkylation catalyst but also in the pharmaceutical industry (pharmaceutical products synthesis), on construction sites (building facade cleaning) and in surface treatment (pickling) or uranium treatment.

Hydrogen fluoride effects on health

Hydrogen fluoride (HF) is a colorless gas featuring a pungent smell. This gas is very toxic by inhalation (R26), if swallowed (R28) or in contact with the skin (R27). It reacts with water to form hydrofluoric acid, which is very corrosive and extremely dangerous for the environment – it changes water pH. Even if this gas is not flammable, it reacts with almost any metal in presence of humidity and produce hydrogen (H2) – and highly flammable gas.

Hydrogen fluoride gas detector - HF

Hydrogen fluoride is detectable through smell, however only an HF gas detector can accurately measure concentrations of this extremely toxic gas. It is recommended to use a fixed or portable ppm hydrogen fluoride gas detection system.

Especially designed to monitor exotic gases, the X-am® 5100 single gas detector accurately detects hydrogen fluoride (HF), nitric acid (HNO3), hydrogen bromide (HBr), hydrogen chloride (HCl), hydrazine (N2H4), phosphorus oxychloride (POCl3 or PCl3) and hydrogen peroxide (H2O2).

  • Drager portable exotic gas detector
  • Lightweight (220g), robust and insensitive to electromagnetic radiation
  • User-friendly 2-button interface
  • Visual, audible (90 dB) and vibrating alarms
  • Data logging
  • ATEX, CE, IECEx, CSA us (class I, Division I) approved

Additional information

PortaSense II gas leak detector is a single-gas detector to monitor rare gases. This device is powered with a D alkaline battery for around 75 hours runtime and an internal Nicad battery with an autonomy of around 6 hours.

The PortaSense gas leak detector can detect many gases thanks to its large range of interchangeable sensors. Majors detected gases are: alcohol, B2H6, Br2, C2H2, CH2O, Cl2, ClO2, CO, COCl2, F2, acid gas, GeH4, H2, H2O2, H2S, HCl, HF, NH3, NO, NO2, O2, O3, PH3, SiH4. In complement to this detected gases, this monitor features different measuring ranges for every gas.

The PortaSense II primarily detect gas leaks with its integrated sampling pump. This enables accurate measurements of hazardous gas concentrations. This gas leak detector with interchangeable sensors is moreover calibration-free, which makes it very versatile.

This single-gas detector features audible and audible alarms with 3 levels: caution, warning, and alarm with adjustable setpoints. A fourth alarm will indicate a low flow or low battery.

Thanks to its internal memory, the detector can record event data during 8 days with 1 minute interval. Furthermore, Portasense II features an RS32 output to connect a PC for data downloading.

HF respiratory protection - Hydrogen fluoride

As hydrogen fluoride is irritant to the eyes, it is advised to use a full face mask for short interventions or a full powered air respirator equipped with an E-P3 combined filter. If concentrations exceed 60 times the OEL, a self-contained breathing apparatus (SCBA) is required.

The VISION panoramic gas mask is compatible with particle, gas and combined filters. It can also be used as a facepiece for powered air respirators and SCBA.

  • Large field of wiew (98%) without visual distorsion
  • Reinforced visor resistant to solvents and scratches
  • Two filter mounting locations: central or right side
  • LSR face seal (liquid silicon rubber)
  • Available in 3 different sizes for optimal comfort
