The health authority warns in a social media post that older buildings constructed before 2005 may contain asbestos-containing materials, including roof tiles, cladding panels, and ventilation pipes.

According to the DGS, "the danger arises when these materials are damaged, releasing invisible fibres that can be inhaled," with health consequences.

Therefore, the public is urged not to touch, cut, or break any materials suspected of containing asbestos.

People should stay away from the area and avoid sweeping or vacuuming, as these actions can disperse fibres into the air.

The Directorate-General of Health also warns that the removal and management of asbestos-containing waste can only be carried out by licensed operators.

In cases where materials suspected of containing asbestos are already in the soil or are considered waste, the Portuguese Environment Agency (APA) or the territorially competent Regional Coordination and Development Commission (CCDR) should be contacted.

The DGG (Directorate-General for Geology and Geophysics) emphasises that the removal of tiles or other installed materials must be carried out by a certified company to ensure the safe repair of spaces.

“There are risks that are not visible, but can also cause damage after a storm,” it states, appealing to the population to protect themselves, stay informed, and ensure that “any intervention on materials suspected of containing asbestos is carried out in complete safety.”
