The document summarizes four key cases related to negligence and foreseeability of damages:
1) Re Polemis - A shipowner sued a charterer after benzene leaked on board and was ignited by a spark, causing an explosion. The court held the charterer liable as the explosion was a direct consequence of their servant's negligence.
2) The Wagon Mound (No: 1) - Oil leaked from a ship and later ignited, destroying a nearby wharf. However, the court found the defendants not liable as the risk of fire could not have been foreseen.
3) Hughes v Lord Advocate - A man was injured after a lamp dropped into an unguarded manhole
