The regulator is connected to a breathing mask for the crew member. A protective hood supplied with filtered ventilation air is provided for location over the head of the crew member. The regulator has a housing containing the regulating mechanisms and an intake for dilution air and is surrounded by a case defining a protective space about the housing. The space is fed with filtered air under an overpressure of the same order as that which prevails in the hood.
