    摘要: The life-saving appliance (1) is arranged in a covering (5), which is evacuated. So that the covering (5) cannot be damaged, it is enclosed in a hard foam casing (6). Through openings (7, 8) the life-saving appliance (1) can be released from the casing with the help of a pull member (4), or the vacuum in the covering (5) can be tested by touching the latter.
