Portable gas detectors training

Any person who has to use a portable gas detector must know certain basic principles for optimum use and to reduce as much as possible all the risks related to interventions in hazardous areas or in confined spaces. For these reasons, a training in the use of portable gas detectors is strongly recommended wherever: in our facilities, on-site at our customers' office or via Teams for those who are too far and the most distant of them.

Presentation of gas detectors training

  • Teaching objectives: The main purpose of this training is to understand the main risks induced by the presence of gas, to know the main effects on health and especially to know how to use the different portable gas detectors
  • Relevant public: The gas detectors training is addressed to any person likely to or having to intervene in a gas risk area
  • Number of attendees: This training can be followed by a group of 10 people maximum
  • Duration: About two hours
