ATEX studies
For the mounting components in a stationary or on-board hydrogen system, H2TEAM carries out ATEX studies according to standard EN 60079-10-1 in order to classify ATEX zones in the event of dysfunctional leaks at low, medium and high pressure.
The objective will be to reduce risks as much as possible by declassifying these ATEX zones and analyzing the behavior of each case of leaks identified.
These studies aim to check the quality of hydrogen dilution in the air, to locate the leak (with shape, orientation, calculation of the net surface area of the ventilation openings, etc.), to interpret and propose technical solutions for eliminating dangerous hydrogen accumulation zones in cases of accidental leaks.

Explosion risk study
The explosion risk can be a consequence of dysfunctional leaks and must be considered to avoid the worst scenarios, including pipe ruptures.
This study will analyze the leak profile and its position to study the worst possible scenario in order to calculate the dispersion of leaks through ventilation.
Generally, the cases studied are linked to the immediate ignition of the leak with creation of a flare, the jet explosion, the explosion of the background concentration cloud. Following these studies, the level of severity targeted during an incident must be zero or low.
