    • An immersion suit (10) is largely formed from a plurality of panels. Each panel has an outer layer (41) that is fire- or flame-resistant and an inner layer (42) which provides water vapour permeability and which is substantially impermeable to water when immersed in water. The inner and outer layers (41, 42) of each panel are unconnected in a substantial continuous area of each panel. In use, the inner layers (42) prevent entry of water into the suit when the suit is worn by a wearer immersed in water. The outer layers (41) protect the inner layers (42) when the suit is worn during exposure to a flash fire. In this way, if the wearer subsequently becomes immersed in water, the inner layers (42) are still able to prevent entry of water into the suit. As the inner and outer layers (41, 42) are largely unconnected (and not bonded together), this helps to maximise the water vapour permeability of the suit (10) and helps to reduce conduction of heat between the two layers (41, 41). Additionally, attachments to the suit such as pockets can be stitched to the outer layer (41) only. As the inner layers (42) are not penetrated by this stitching, sealing of the inner layers (42) in the vicinity of the stitching is not necessary.
    • 浸入式衣服(10)主要由多个面板形成。 每个面板具有耐火或阻燃的外层(41)和提供透水性的内层(42),并且当浸入水中时基本上不透水。 每个面板的内层和外层(41,42)在每个面板的基本上连续的区域中是未连接的。 在使用中,当穿用者浸入水中时,内层(42)防止水进入衣服。 当暴露于闪光火焰期间穿着西装时,外层(41)保护内层(42)。 以这种方式,如果穿着者随后浸入水中,则内层(42)仍然能够防止水进入衣服。 由于内层和外层(41,42)在很大程度上未连接(而不是粘合在一起),这有助于最大化衣服(10)的水蒸气渗透性,并且有助于减少两层(41,41)之间的热传导 )。 此外,衣服的附件如口袋可以仅缝合到外层(41)。 由于内层(42)没有被该缝合穿透,所以不需要在缝合附近密封内层(42)。
