Over the years, Gard has handled numerous cargo claims where condensation was found to be the contributory cause of cargo damage. When dealing with such claims, the voyage records of the hold ventilations play a central role in mitigating the claim.
The need for ventilation arises when there is a potential for condensation to form within a cargo hold. This can start to happen when the outside air temperature is lower than the dewpoint of the air inside the cargo hold. This can result in surface condensation. The only way to minimise or prevent moisture condensation inside the cargo hold is through proper ventilation. An aide mémoire which mariners can rely on is ‘Hot to cold ventilation bold [or hold], and cold to hot, ventilate not’.

通风记录 – 针对高额货物湿损的抗辩
多年来，Gard协会处理了许多货物索赔，这些案件中冷凝水被认为是造成货损的主要原因。在处理此类索赔时，货舱通风的航行记录在减轻索赔中起着重要作用。
货舱内有形成冷凝水的可能性时，就需要通风。当外部空气温度低于货舱内空气的露点，这种可能性就会存在。这会导致表面水汽凝结。适当通风是减少或防止货舱内水汽凝结的唯一方法。有句俗语可以帮助水手们记忆需要通风的情况，“由热至冷，大胆（或保持）通风，由冷至热，无需通风”。
