International workshop of first responders 5-6 October 2020, Virtual meeting

The “international virtual workshop of first responders” was held as an online event. More than 150 people registered for the event. These were members of the projects HyTunnel-CS and HyResponder, first responders from fire services, operators of underground transport systems (UTS), regulatory and safety authorities, manufacturers of hydrogen-powered vehicles, etc.

The International workshop addressed several topics, including but not limited to the analysis of current procedures of fire services for incidents with hydrogen in underground systems. In this context, the following questions were included into discussion, to gain consistent understanding of possibilities and limitations of first responders’ intervention, especially firefighters:

  • What are the specific conditions for intervention in underground transportation systems?
  • How do first responders get all relevant information needed?
  • What are the possible actions taken by fire-fighters?
  • Why is ventilation a very important factor?
  • Who is responsible for which measures of response?
  • What behavior by persons involved must be taken into consideration?
  • Which issues need further research?

The possible tactics and techniques for intervention were presented and discussed, e.g. the benefits and risks of ventilation in tunnels, car parks, etc. The focus was on how the outcomes of HyTunnel-CS research can aid the development and optimization of the fire services intervention strategies, tactics, procedures, technical equipment, training, etc. 

One of the main findings of the workshop was that technologies like TPRD-less tanks would significantly reduce or even eliminate many risks of hydrogen-powered vehicles. For many participants of the workshop this was a completely new perspective for the future. At the same time, it became clear that despite these innovative security technologies, specific hazards will remain. These should be identified in the course of HyTunnel-CS project, to review how the tactics and techniques recommended so far for dealing with incidents involving hydrogen-powered vehicles need to be adapted accordingly.

The most important recommendation at this stage is to ensure that firefighters are informed about the involvement of hydrogen in an accident as early as possible.

Workshop goals

Day 1

–       Overview of projects HyTunnel-CS and HyResponder;

–       Share knowledge on interventions in underground transport systems in general.

Day 2

 

–       Interactive discussion of appropriate tactics for response to Hy-incidents in tunnels and similar confined spaces;

–       Exchange of views on education and training for Hy-Response in tunnels and similar confined spaces;

–       Identify questions that need further scientific clarification;

–       Synchronization with partners activities.

The attendance of the workshop was free of charge as the project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (JU) under grant agreement No 826193. The JU receives support from the European Union’s Horizon 2020 research and innovation programme and United Kingdom, Germany, Greece, Denmark, Spain, Italy, Netherlands, Belgium, France, Norway, Switzerland.
