通过协会近些年发布的各种通函、新闻警告和防损公告，会员已经熟悉了运输易液化货物的危险。但一直以来主要的关注点是印度和巴西的铁精粉运输，以及菲律宾和印尼镍矿的运输。
然而，协会之前报道过，在巴西装运的铝矾土有可能液化（相关文章，请点击 这里 ）。近期，协会得知印尼铝矾土货物也存在这一风险，因为印尼的矿山中使用高压水炮冲刷铝矾土粉和铝矾土块使其通过滤网。这一处理极大地增加了货物的含水量，据报道冲刷后铝矾土的含水量比在堆场时高出约15%。这使得货物的性质从低含水量，通常不液化，转变成在航程中容易液化。货物液化会导致货物移动及船舶失去稳性，这也是海上事故的主要原因之一。

Liquefaction – Potential Dangers of Indonesian Bauxite
Members will be aware of the dangers associated with the carriage of cargoes that can liquefy from the various Circulars, News Alerts and Stop Loss articles issued by the Club over recent years. The primary focus of concern has been in respect of the carriage of iron ore fines from India and Brazil, as well as nickel ore from the Philippines and Indonesia.
However, the Club has previously reported on possible liquefaction of Bauxite cargoes loaded in Brazil (for the relevant alert, please click here ). Recently, the Club has learned of the potential risks arising from the practice of using water cannons to wash Bauxite fines and lumps through sieves in mines in Indonesia. This process significantly increases the moisture content of the cargo, reportedly to approximately 15% by the time the Bauxite is placed in the storage area. This changes the properties of the cargo from one with a low moisture content that is not ordinarily prone to liquefaction, to a cargo which may liquefy during a voyage. Liquefaction of cargo results in cargo shifting and loss of ship stability, a major cause of marine casualties.
