Confined space air monitors & safety solutions for confined space entry

Confined spaces are partially or fully closed structures (pits, tanks, sewers…) present in many industries. Risks generated because of a poorly oxygenated, toxic or explosive atmosphere are serious and oftentimes cause severe accidents and deaths. Thus  the use of a confined space air monitor and other safety solutions are essential.

confined space air monitor & safety solutions: portable 4 gas detectors and self rescuer masks

CONFINED SPACES

A confined space is a partially or totally closed structure that has not been designed to be permanently occupied by workers. Operating inside (confined space entry) must remain exceptional: during their construction, their servicing (particularly while cleaning) or their maintenance (periodical checking, repair).

Application areas

  • Waste water treatment : chlorination, ozonation
  • Crawl spaces, sewers, drains, pipes
  • Mines, long and thin galleries
  • Cisterns, tanks, containers
  • Wells, sinks, pits, silos and cellars

CONFINED SPACE ENTRY

Major confined space hazards

The majority of accidents – oftentimes severe or lethal – that occur during confined space entries are due to oxygen deficiency, presence of toxic gas or vapor and explosion or fire. Thus these are the first hazards to monitor while forecasting an intervention on this kind of site.

  • Asphyxia, anoxiaor hypoxia : temporary or definitive lack of oxygen that can lead to death
  • Intoxication: intoxication is due to inhalation or absorption of a toxic substance (hydrogen sulfide, carbon monoxide, hydrogen cyanide) which can cause death
  • Explosion and fire: presence of flammable combustible gas (natural gas, butane, propane, hydrocarbon vapors) or dust can trigger fire and explosion

Risk prevention for confined space entry

It is highly recommended to organize in advance the practicability and the required prevention means before any confined space entry. In addition to classic PPE (helmet, gloves, safety footwear, boots…) it is prescribed to use a 4 gas monitor for confined space (combustible gas, oxygen deficiency, carbon monoxide and hydrogen sulfide) and to have a self-rescuer respirator for emergency evacuation…

CONFINED SPACE TRAINING

Any worker – such as construction workers, HVAC technicians or firefighters – who can potentially work in a confined space environment need to receive proper confined space training, depending on the risk level of their activity.

Confined space awareness courses are elaborated so that learners understand more about safe work practices, suitable gas monitoring equipment use, and to teach what the regulations sates regarding work safety.

Thanks to local training (like OSHA confined space training in the USA, CATEC® training in France, and different confined space certification in other territories), workers evolving in these environments have knowledge of their legal responsibilities under confined spaces regulations and other related legislation. They also understand how to prevent and react to various risks. Once trained, workers are aware of the dangers of working in confined spaces and understand the importance of implementing appropriate control measures and necessary emergency procedures.

Portable gas detectors and area gas monitors for confined spaces

The most commonly used confined space air monitor is the 4 gas confined space meter which simultaneously monitors combustible gas (methane), oxygen (O2), carbon monoxide (CO) and hydrogen sulfide (H2S).

The Blackline Safety G7 EXO area gas monitor is a new generation geolocated and connected equipment which transmits positions, measurements and alerts in real time on a cloud-based control platform and to the devices connected to its network.

Simultaneous detection of up to 5 gases: Cl2, ClO2, CO, CO2, H2, H2S, HCN, NH3, O2, O3, SO2, combustible gas and VOC.

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.

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.
