Por que os bombeiros deixam água SUJA do hidrante vazar na rua?🚒 Quando os bombeiros abrem um hidrante e a água sai escura, parece desperdício, mas não é. Isso é a ''Descarga de Hidrante''. Ela remove sujeira, areia e ferrugem e testa a pressão da água. Porque num incêndio real, se a pressão falhar… o jato não alcança as chamas. #curiosidades #bombeiros #educação #firefighter
