The authorities' recommendations to prevent accidents and carbon monoxide poisoning include: not using generators in enclosed spaces, even with doors or windows open; keeping the device at least 6 meters from the house; and directing exhaust gases away from dwellings.

In a social media post, the DGS and the National Emergency and Civil Protection Authority (ANEPC) state that “due to Storm Kristin, there may be a need to use generators for power production,” but warn that it is essential to know the associated risks and ensure their safe use.

Authorities warn that carbon monoxide is an invisible, odourless, toxic gas that kills silently, especially at night or while sleeping.

They emphasise that even a small generator releases enough carbon monoxide to kill in 10 to 15 minutes in a closed or semi-closed space.

The DGS (Directorate-General of Health) and ANEPC (National Emergency and Civil Protection Authority) urge people to immediately call 112 if they detect carbon monoxide release or experience symptoms of poisoning.

If there is suspicion, everyone should immediately go outside and remain there until authorised by professionals.

Symptoms to watch for include persistent headache, dizziness or feeling faint, nausea and vomiting without apparent cause, unusual tiredness or weakness, confusion, difficulty thinking or speaking, excessive drowsiness, and shortness of breath.

Authorities warn that inhalation of this gas can lead to loss of consciousness or death.
