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.

The colorimetric gas detection tube system is a simple and accurate solution composed by a manual sampling pump and a specific gas detection tube. They are designed for use together.

  • Gas detector tubes Colorimetric tube
  • Accurate: the sampling pump features a mechanical accuracy piston which creates a vacuum then enables direct reading on the colored tube (colorimetric tube)
  • Swift: one or two pump strokes are enough to draw sample and the value can be directly read on the tube
  • User-friendly: no knowledge, no specific process and no technical competence are required

Its rugged housing is IP54 certified which enables the X-am 5100 to be used in demanding environments with a temperature range from -20 to 50°C and a relative humidity from 10 to 90%. This portable gas detector is also schock-resistant and immune to electromagnetic emissions.

The X-am 5100 is available in three versions. The first one is powered with a rechargeable NiMH battery which gives the detector an autonomy of around 150 hours. The second version is powered with a rechargeable high capacity NiMH battery which gives the detector an autonomy of around 180 hours. Lastly, the third version is powered with alkaline batteries which give the detector an autonomy of around 150 hours runtime.

Thanks to its intuitive menu and its two ergonomic buttons the X-am 5100 portable single-gas detector is easy to use and requires no special technical skills to operate. Moreover, it can easily be placed closed to the breathing tracts thanks to its crocodile clip in order to get measured concentrations as close as possible to those inhaled by the operator.

Its integrated datalogger can store more than 100 hours of data with interval of 1 value per minute. This data can then be retrieved or transferred to a computer with an infrared interface integrated on the device.

The X-am 5100 is delivered ready for use with a charger and a calibration certificate.

The X-plore 800 PAPR respirator system has been especially designed to enable its user to operate safely in toxic environments. Thanks to its robust designIP65 certified against dust and water jets – this positive pressure air purifying respiratory protective device is particularly well-suited for use in potentially explosive atmospheres (ATEX).

The X-plore 8000 PAPR respirator system is composed by a rugged casing that can includes a whole range of specific PAPR filters in order to meet requirements of almost any industrial application. A breathing hose available in three different versions and a face piece (PAPR mask or hood) complete this system. The device can be worn with a special belt and can be equipped with a standard battery, which provides at least 4 hours run time, or a high capacity battery for an extended run time of at least 8 hours. The belt ensures optimal comfort of use and perfect weight balance. This positive pressure respirator has been especially engineered to fit perfectly the user without disturbance.

Available in standard version as well as ATEX certified fireproof version, the X-plore 8000 respirator features protected air inlets which ensure that no dust, water or even sparks come into contact with filters.

Thanks to its enhanced technology, the PAPR respirator system automatically detects the connected face piece in order to adjust the injected airflow. Integrated temperature and pressure sensors in the housing also enable the automatic adjustment of the airflow. A wide range of face pieces – PAPR hoods & masks - is available to meet even the most demanding requirements from any application. This way, the housing of the X-plore 8000 can be connected to half-hoods, full hoods, protective visors, helmets, half-masks, panoramic masks or even helmets specifically dedicated to welding activities.

The X-plore 8000 PAPR respirator also features a smart alarm system which purpose is to alert user in case of problems. This way, if the air flow is not sufficient or in case of low battery status, visual (operational display), acoustic (80 dBA at 1 meter) and vibrating alarms activate to alert user of the failure. Moreover, an integrated optical sensor avoids any use without a filter for an optimal safety of use.
