Você sabe a diferença entre Flashover e Backdraft? . . A diferença é técnica, o risco é real. Confundir esses fenômenos muda o desfecho. . . . No Flashover, o oxigênio está presente e a radiação térmica sobe até a ignição generalizada do ambiente. Sem impacto, sem barulho, sem aviso. O cenário inteiro colapsa. . . No Backdraft, o fogo está contido. Pouco oxigênio, gases quentes acumulados. Abriu a porta, o ar entra e a reação é imediata: explosão violenta. . . Isso não é detalhe técnico. É COMUM
