4-5. General Stowage Procedures
Explosives are dunnaged below decks by use of either of' the following equivalent methods:
a. Block Stowage. Loads are stowed in the form of a tight block between parallel securing structures constructed at
both sides of the hold, or they are confined by other loads or wooden bulkheads if warranted by the size of the load.
Block-stow techniques are advantageous in that undesirable void areas within the stow are minimized. The blockstow
technique is described fully in chapter 8.
b. Sweatboard-to-Sweatboard Stowage. This technique requires that loads stowed along the sides of the hull be
made to bear against strip sheathing and be parallel with the ship's center line. Therefore, unless the hull's angle fore
and aft (chamber) at this particular stowplace is parallel to the ship's center line and the vertical angle of the hull (sheer)
is perpendicular to the deck, only one corner of the load is brought to bear at the strip sheathing. A tight stow is
achieved, provided that longitudinal movement is blocked and that subsequent loads comprising the complete stow are
placed so that each row of unit loads bears against both the strip sheathing and its neighboring row. A more detailed
description of this method of stowing is provided in chapter 8.
4-6. Use of Power-Operated Industrial Trucks
Army activities should refer to 46CFR146.9-15 to determine the proper equipment necessary for safe loading operations.
All Navy activities are required to comply with NAVSEASYSCOM OP 4098, "Handling Ammunition, Explosives, and
Hazardous Materials with Industrial Materials Handling Equipment (MHE)."
