Gas monitoring for tunnels and underground

Road and railroad tunnels are considered as closed or partially closed structures. They feature same risks and hazards than interventions in confined spaces, such as oxygen deficiency and potential presence of combustible or toxic gas or vapor.

gas detection equipment ans scsr masks for tunnel and underground worksites

A confined space is a closed or partially closed structure and most of severe or lethal accidents that occur while entering these areas are linked to combustible, toxic or asphyxiating (lack of oxygen) gases. These will be the main risks to evaluate within a gas monitoring safety process for tunnels and underground work using portable gas detectors and area gas monitors.

GAS EXPOSURE IN TUNNELS

Chronic exposure to exhaust gases can cause severe neurological disorders (headaches, dizziness, irritability, drowsiness, convulsions), bronchial irritations or even lungs cancer in some cases. It is thus essential to permanently measure and control TWA (time weighted average) and STEL (short term exposure limit) exposure values in road and railroad tunnels for:

  • Carbon monoxide
  • Carbon dioxide
  • Nitrogen oxides (nitric oxide and nitrogen dioxide)
  • Sulphur dioxide
  • Volatile organic compounds (VOC) including benzene
  • Oxygen defficiency

GAS DETECTION FOR TUNNELS

Multigas detector and area gas monitor

Concerning personal protection, a multigas detector remains essential and indispensable. In addition, a area gas monitor will secure the working area. For very long tunnels, it will be advisable to use units with communication solutions as explained below…

LENS Wireless technology

Particularly suitable for tunnels, the LENS™ Wireless technology is a new way to approach safety. With this technology, once a detector or an area gas monitor enters in alarm following a gas hazard, a « man in distress » alarm or a panic situation, every paired detector will get instant alert.

respiratory protection and self-rescuer mask

Self-rescuer masks a respiratory protective devices especially designed for emergency evacuation in non-breathable atmosphere – poorly oxygenated, smoky or extremmely toxic areas – for use when an air purifying respirator would be unefficient or hazardous. They originally have been designed for emergency evacuations from mines or long tunnels.

GAS DETECTION FOR TUNNELS

The most commonly used and the most cost-effective unit for confined space applications is the 4 gas detector (combustible gases, O2, CO and H2S). Yet for tunnels it advisable to use a multigas detector with CO-CO2-NO-NO2-O2 sensors. For emergency evacuation, a self-rescuer respirator remains indispensable!

Especially designed to simultaneously detect from 1 up to 7 gases, the X-am 8000 portable multi gas detector can also be equipped with an external sampling pump to draw remote samples. For combustible gas (catalytic or infrared), amines, Cl2, ClO2, CO, CO2 (electrochemical or infrared), H2, H2S, HCN, NH3, NO, NO2, O2, O3, PH3, SO2 and volatile organic compounds (10.6 eV PID lamp) monitoring.

  • Colored display for easy readouts
  • Impact detection system
  • Optional external gas sampling pump
Additional information

Especially designed for use in pump mode or diffusion mode, the X-am 8000 portable multi gas detector can simultaneously monitor up to 7 gases.

 

Particularly well-suited to perform control measurement before operating in confined spaces, the 7 gas monitor X-am 8000 can be equipped with an external sampling pump available in option. Using the pump mode is very convenient and useful to monitor spaces hard to access. Easy to mount and to remove, this pump requires no tools and is it very easy to switch from diffusion mode to pump mode.

 

Compact and discrete, this portable 7 gas monitor features 3 navigation keys and a colored display for easy and swift measurement values readout. Very convenient, this detector has been engineered for one-handed operation. As it is also robust and rugged, this multi gas detector is extremely efficient in hostile environments and in the harshest conditions.

 

This device also features three bright LED indicators based on a color code compliant with the NF EN 60079-29-1, NF EN 45544-1 and NF EN 50104 standards. This way, the red light indicates an alarm due to hazardous concentrations gas; the yellow light an alarm is related to a device failure –like a low battery status for example - and the green light indicates the proper operation of the device and that it is ready for use. In case of an alert event, audible (110 dB at 30 cm) and vibrating alarms are activated in addition to the visual alarm.

 

The 7 gas monitor X-am 8000 also integrates an impact detection system. This way, any mechanical impact that can damage the device is stored in the device’s memory. This data is stored in the device internal memory that can also store data on hundreds of exposure hours.

 

Lastly, the X-am 8000 portable mutli gas detector is powered by a lithium-ion battery that can be charged through an induction charger. Thanks to this innovative non-intrusive charging system, common issues from standard charging systems are removed – such as pin corrosion and contact problems.
