Grand\u00a0Paris project,\u00a0<\/strong>gas detection in tunnels<\/strong>\u00a0It is a perfect example of its importance. around Paris\u00a0transportation network<\/strong>\u00a0This massive project, aimed at improving and expanding,\u00a0includes the construction of many new tunnels.<\/p>\n

There have been five deaths and several serious accidents since work began, making\u00a0The Grand Paris Express has once again revealed the major safety challenges at its construction sites. This\u00a0<\/strong>, gas detection tools<\/strong>\u00a0, sufficient\u00a0to security devices<\/strong>\u00a0and emphasizes the need for\u00a0continuous employee training .<\/p>\n

Workers in these fields\u00a0toxic and explosive gases<\/strong>\u00a0And\u00a0limited working conditions<\/strong>\u00a0It faces high risks such as . Therefore,\u00a0to ensure their safety and prevent serious accidents.\u00a0multi-gas detectors<\/strong>\u00a0,\u00a0tracking signs<\/strong>\u00a0or like OXY SR\u00a0Self-rescuers are a must.<\/strong><\/p>\n

A confined space\u00a0is an enclosed volume, and most serious or fatal accidents that occur during work in these environments are related to the presence of explosive, toxic or asphyxiating substances (lack of oxygen). These will be the first risks to be assessed when developing a working procedure for safety with devices for detecting gaseous emissions in tunnels.<\/p>\n

Which gases need to be monitored in tunnels?<\/h2>\n

Chronic exposure to exhaust gases can lead to significant neurological disorders (headache, dizziness, irritability, drowsiness, convulsions), bronchial irritation and sometimes lung cancer. Therefore, in road or railway tunnels mean values \u200b\u200b(VME) and limit values \u200b\u200b(VLE) of exposure to detect gaseous products <\/strong>measure and continually monitor<\/strong> It is mandatory:<\/p>\n

    \n
  • Carbon monoxide<\/li>\n
  • Carbon dioxide<\/li>\n
  • Nitrogen oxides (nitric oxide and nitrogen dioxide)<\/li>\n
  • Sulfur dioxide<\/li>\n
  • Volatile organic compounds (VOCs), including benzene<\/li>\n
  • lack of oxygen<\/li>\n<\/ul>\n

    Sensors for gaseous substances in tunnels<\/h2>\n

    Multiple gas detector and area monitoring sign<\/h3>\n

    personal protection<\/strong>\u00a0Regarding\u00a0,\u00a0multi-gas detector\u00a0continues to be essential PPE, as does\u00a04-gas detector. You can also secure one or more work areas\u00a0with field gas monitors to better define the safety perimeter. For very long tunnels, we recommend communication solutions as shown below\u2026<\/p>\n

    LENS Wireless technology<\/h3>\n

    Particularly suitable for tunnels\u00a0<\/strong>LENS\u2122 Wireless technology<\/strong>\u00a0,\u00a0is a new approach to safety on a construction site. With this solution, a\u00a0gas detector<\/strong>\u00a0or\u00a0field tracking beacon,<\/strong>\u00a0When an alarm is triggered following a toxic product hazard, a \u201cman in distress\u201d alarm, or a panic situation, all persons in the connected group will immediately know about the danger.<\/p>\n

    Gas detection \u2013 protection for TBM operators<\/h2>\n

    The most commonly used (and cheapest) model for operations performed in confined spaces\u00a0It is a portable 4 gas detector<\/strong>\u00a0(explosive gases, O2, CO and H2S). But if you want to be more relevant for tunnels, you can use\u00a0CO<\/strong>\u00a0–\u00a0CO2<\/strong>\u00a0–\u00a0NO<\/strong>\u00a0–\u00a0NO2<\/strong>\u00a0–\u00a0O2<\/strong>\u00a0You can choose a multi-gas sensor that is ideally configured to detect cells. Some can monitor up to 6 gases simultaneously. Available in a diffusion version or with a remote sampling pump, this sensor is perfectly suitable for hazardous areas, environments that are potentially explosive, toxic, suffocating or contain VOCs (volatile organic compounds).<\/p>\n

    One of the most reliable tunnel work transmitters\u00a0Dr\u00e4ger's X-am 5000 portable detector<\/strong>\u00a0Dr\u00e4ger's X-am 5000 portable detector\u00a0personal tracking device,<\/strong>\u00a0potentially explosive gases and vapors,\u00a0Detects oxygen deficiency and toxic gas concentrations. Generally\u00a0<\/strong>clip pump<\/strong>\u00a0,\u00a0sampling hose<\/strong>\u00a0and comes with accessories such as workplace beacon\u00a0.<\/p>\n

    To guarantee safe operation, sensors in the tunnel industry need to be checked regularly. Companies\u00a0find themselves doing a calibration or process to check the operation of that sensor.\u00a0Equips with crash test station.<\/strong><\/p>\n

    Whether in France or Europe, people working in tunnels have masks and detection devices, etc.\u00a0Respiratory protection equipment must be used.<\/strong><\/p>\n
