Cultural Tip
In Brazil, many families light candles during power outages, but this can be a fire risk, especially in homes with flammable décor. Municipalities often distribute lanternas (battery‑powered flashlights) as a safer alternative. Using the imperative form 'Usa' is informal; in a formal setting you would say 'Use lanternas, não velas.'
