ABSTRACT:
An individual breathing equipment comprises a head covering provided with a neck joint defining a space which is separated from the outside all around the head and a mask for isolating the respiratory tract. The mask is provided with a breath-in valve and with a breath-out valve exhausting directly to the atmosphere. The breathable gas feed circuit opens into the space defined by the head covering. The outlet of the feed circuit and the outlet of the breath-in valve for taking air from said space are so located that the breathable gas ventilates the head before reaching the breath-in valve. A buffer volume is placed upstream of the opening into said space, defined by a breastplate.
