Acetylene – C2H2

This page presents information about acetylene (C2H2), appropriate detection means – C2H2 gas detector – and respiratory protective equipment (self-contained breathing apparatus and supplied air respirator).

C2H2 gas detector and acetylene respiratory protection

Acetylene properties

Acethylene (C2H2) – also known as Ethyne – is a compound from the alkynes group. This gas is oftentimes used in the chemical industry as base material in organic compounds synthesis (such as acrylate or chloroethylene). Acetylene is also used during hydrocarbon cracking process (petroleum refining) and while welding with temperatures up to 3,000°C.

Acetylene effects on health

At ambient temperature, ethyne is a colorless and theoretically odorless (when it is a pure gas). Even if this gas is not toxic, respiratory hazards may lead to suffocation. It is extremely flammable (R12) and features risks of explosion (R5) with or without air contact (R6). It basically reacts with almost any oxidizer and can compose toxic and/or corrosive gas mixtures even at low concentrations.

C2H2 gas detector (Acetylene)

As acetylene is colorless and odorless when pure, only a C2H2 gas detector can accurately measure concentrations of this gas. Two acetylene detection methods are available: either in toxicity with a ppm measurement (PortaSens), or in explosivity with LEL percentage measurement (combustible gas detector).

Portable 4 gas detector – VENTIS-MX4 – EXLO, O2, CO, H2S

VENTIS-MX4 portable gas detector that complies with ATEX standards. This detector can detect from 1 to 4 gases with a large range of sensor combinations (Explo 0-100% LEL, O2, CO, H2S, NO2, SO2).

Portable gas detector MX4-Ventis
  • Detection of Explo (0-100% LEL), O2, CO, H2S, NO2, SO2
  • Robust, shock-resistant and waterproof device (IP66 and IP67)
  • Enhanced visibility with safety orange overmold
  • Compact and lightweight: first multigas detector with a single-gas detector size
  • Optional slide-on sampling pump (up to 30 meters)
Additional information

The Ventis-MX4 is a portable multigas detector. Contrary to single-gas detectors, it can detect up to 4 gases. Thanks to its rechargeable Li-ion battery, it can continuously operate during around 12 hours at 20°C ambient temperature. This battery can be replaced by an optional extended battery for up to 20 hours of autonomy without pump.

The Ventis-MX4 portable gas detector can detect up to 4 gases amongst explosive gases, oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide (SO2) and nitrogen dioxide (NO2). A specific location is dedicated to the explo sensor (catalytic sensor) and the oxygen sensor (electrochemical sensor). A 4 gas unit will basically include oxygen and explo sensors.

The Ventis-MX4 features 3 different alarms. The first one is a powerful 95 dB at 30 cm audible alarm to alert in noisy environmets. A high visibility red LED visual alarm and an ultra- vibrating alarm are added to improve safety. Two alarm levels are configures: low and high alarms – which are basically calibrated under occupational safety at work data.

The Ventis-MX4 portable gas detector also features the same physical properties – dimension and weight – than a single-gas detector. It can be wore close to the breathing tracts thanks to its crocodile clip without disturbing the user. This multigas detector shock-resistant and waterproof thanks to its high visibility polycarbonate-made overmold.

As this device can detect explosive gases, it meets current EU ATEX standards (explosive atmosphere). A sampling pump – VSP for Ventis-MX4 – is available to draw remote samples (up to 30 meters) before interventions – e.g. in confined space.

Portable multi gas detector – VENTIS PRO5 – up to 5 gases

The Ventis Pro5 detector is equipped with new features such as a panic button to improve safety of workers evolving in hazardous areas.

Detection of the combustible gases, NH3, CO, CO/H2S, H2S, HCN, NO2, O2, SO2, CO2, HC.

  • Dimensions: 104 x 58 x 36 mm – weight: 200 grams without pump
  • Audible (95 dB), LED visual (2 red and 2 blue) and vibrating alarms
  • Rechargeable lithium-ion battery with optional extended battery
  • Polycarbonate housing with waterproof rubber overmold (IP68)
  • Datalogging over 3 months with 10 seconds interval
Additional information

The Ventis Pro5 multi gas detector was especially designed to silmutaneously detect up to 5 gases among the combustible gases, NH3, CO, CO/H2S, H2S HCN, NO2, O2, SO2, CO2 and HC.

 

This flexible detector features a panic button to alert nearby teams when user is in distress. It also features a mandown alert function which is set to activate after a defined period of time without motion.

 

In case of anormal concentrations, powerful audible (95 dB à 10 cm) and visual (ultra-bright blue and red lights) alarms will alert any operator working in the area, even in high-noise and dark environments.

Custom alarm action messages like “EVACUATE” or “VENTILATE” can furthermore be configured in case of emergency situations in order to safely and quickly take corrective actions.

 

Made of polycarbonate with protective rubber overmold, this gas detector is available either in black or high-visibility safety orange versions and can be combined with the VSP slide-on pump. Its integrated data logger can record up to 3 months of events. Water and dust-resistant (IP68), the Ventis Pro5 can be used in pumped version for use in confined spaces or without pump as a personal protective equipment.

 

The Ventis Pro5 portable multi gas detector also features the LENS Wireless technology. LENS is the first wireless gas detection solution that allows personal monitors and area monitors to communicate gas readings and alarms with one another. This way, panic and mandown alarms will be communicated to other Ventos Pro detectors operating in the same area in order to alert everyone on the hazardous situations.

 

Lastly, the Ventis Pro5 benefits from the iAssign® technology for site and user follow-up. Thanks to this enhanced technology, every data recorded by the device will be assigned to the user ID. This process allows amongst other things users to wear several gas detectors within the same working day.
