Abstract

a presente invenção se refere a um sistema de respirador de ar fornecido que indica exposição que compreende um topo de cabeça, uma fonte de suprimen-to de ar limpo e um hub portátil de comunicação pessoal. um topo de cabeça com-preende uma viseira que é dimensionada para encaixar sobre ao menos o nariz e a boca do usuário, um sensor de posição preso ao topo de cabeça e um módulo de comunicação do topo de cabeça. a fonte de suprimento de ar limpo é conectada ao topo de cabeça que fornece ar limpo ao interior do topo de cabeça. o sensor de po-sição detecta se a viseira está em uma posição fechada ou em uma posição aberta e o módulo de comunicação superior da cabeça comunica a posição da viseira ao hub de comunicação pessoal. se o hub de comunicação pessoal receber um sinal que indica a presença de um perigo, e se a viseira estiver em uma posição aberta, um alerta é gerado.
