Waterways - Special Stowage Requirements

Stowage of Cotton or Vegetable Fibers with Rosin or Pitch

Cotton or vegetable fibers transported by vessel must not be placed in the same stowage area with rosin or pitch, unless it is unpractical.

If stowage is unpractical, the cotton or vegetable fibers may be stowed in the same hold or compartment with rosin or pitch if they are separated by clean dunnage or cargo of a non-combustible nature. When such stowage within the same hold or compartment involves large amounts of cotton or fibers or of rosin or pitch, the rosin or pitch must be floored off with at least two layers of 2.54 cm (1 inch) dunnage and the cotton or vegetable fibers stowed above.

Stowage of Cotton or Vegetable Fibers with Coal

Cotton or vegetable fibers must not be stowed in the same hold with coal. They may be stowed in adjacent holds if the holds are separated by a tight steel bulkhead and the cotton or vegetable fibers are dunnaged at least 5 cm (2 inches) off the bulkhead. Cotton or vegetable fibers may be stowed in a hold above or below one in which coal is stowed if there is a tight steel intervening deck and all hatch covers are in place and covered with tarpaulins.
