7-7. Encasement
To prevent contact of the cargo with the ship's structures, such as beams, air vents, conduits, pipes, stanchions, and
ladders, these structures may be covered or encased with wood material. Encasement may be either complete (boarding
over) or partial. Requirements for complete encasement have been almost completely eliminated with the introduction of
palletized cargo, but encasement is required by Federal regulation if the structure is located within an area intended for
class "A" magazine stowage.
a. Complete Encasement. If a metal stanchion, ladder, or other obstruction is located within a class "A" magazine,
the obstruction must be completely encased with wood at least 3/4-inch thick, secured with nails or countersunk screws.
