Abstract: An arrangement for a breathing apparatus, the arrangement comprising a breathing device; a primary connection point; a secondary connection point; a primary side; a secondary side; a first valve arranged between the primary connection point and the secondary connection point, the first valve being arranged to automatically close a first fluid connection between the primary connection point and the secondary connection point when a secondary pressure in the secondary side decreases below a first pressure threshold; and a second valve arranged on the secondary side, the second valve being arranged to automatically establish a second fluid connection between the secondary connection point and the breathing device when a primary pressure in the primary side decreases below a second pressure threshold. A breathing apparatus is also provided.

Abstract: A harness for a breathing apparatus includes an interface member (6) having an elongated shape and being configured for receiving a container of breathable gas of the breathing apparatus. A hip belt (2) is connected to the interface member at a first region (50) of the interface member. A first shoulder belt (16) and a second shoulder belt (18) are connected to the interface member at the first region and at a second region (52) of the interface member. The hip belt and/or the first and second shoulder belts comprise at least one first molded heat resistant plastic material.

Abstract: A method and apparatus are disclosed for assessment of a sealed package. Light is emitted from a narrow-band laser source towards said package from outside of said package. An absorption signal of said light scattered in said package is measured, wherein said absorption is caused by said at least one gas when said light is scattered and travels in said sealed package. Measuring is made outside of said package, whereby said assessment is non-intrusive with regard to said package. It is determined if a deviation exists from a predetermined, expected gas composition and/or concentration of said at least one gas within said sealed package based on said measured absorption signal. Thus sealing of said package for said gas is detected.
