The technology is based on a depressurization process that allows the extraction of carbon dioxide accumulated in basements, ground floors and air chambers of the buildings. To do this, ducts and extraction equipment are installed that channel the gas to non-habitable outdoor areas, where it is released in a controlled way to favor its natural dispersion in the atmosphere without representing a danger to the population.

The special commissioner for reconstruction, Héctor Izquierdo, has stressed the importance of cooperation between administrations and scientific bodies to promote effective solutions to this situation. As he pointed out, this collaboration not only contributes to accelerating the recovery of the affected areas, but also makes La Palma an international reference in the management of volcanic emergencies and in the application of scientific knowledge in the face of natural disasters.

This experimental system is incorporated into other actions that already work in Puerto Naos, such as the network of continuous monitoring sensors and forced ventilation mechanisms installed in different buildings. The ongoing tests will serve to elaborate a protocol that can be applied in those buildings where high levels of CO2 are still detected, with the aim of speeding up the return of neighbours, always guaranteeing safety.
