163:(1706–1790) describe the bulkhead partitions of East Asian shipbuilding. An account of the early fifteenth century describes Indian ships as being built in compartments so that even if one part was damaged, the rest remained intact — a forerunner of the modern day watertight compartments using bulkheads.

Bulkhead also refers to a moveable structure often found in an ((Olympic-size swimming pool)), as a means to set the pool into a “double-ended short course” configuration, or long-course, depending on the type of event being run. Pool bulkheads are usually air-fillable, but power driven solutions do

bulkheads always retain a portion of the bulkhead crossing the head of the opening. Head strikes on these downstand elements are commonplace, hence in architecture any overhead downstand element comes to be referred to as a bulkhead.

In the case of firestops, cable jacketing is usually removed within the seal and firestop rubber modules are internally fitted with copper shields, which contact the cables' armour in order to ground the seal.
