MM3686, Lesson 2
On-deck stowage (stowage out in the open) is authorized for certain classes of military explosives (Figure 2-
4). MILVANs on deck must be properly secured to prevent movement (Figure 2-5). When military explosives
are stowed this way, they must also be at least 20 feet from any incinerator, ash hoist, or coal - or oil-fired galley
or bake shop. If the galley or bake shop is fitted to run electrically, the separation distance must be at least 10
feet. All military explosives stowed on deck must be compatible.
Ammunition found to be defective while being unloaded from MILVANs or railcars is not placed on board
the vessel. However, some items may become defective after being loaded. They should be removed to an
isolated location as quickly as possible.
Sometimes defective packages will be discovered at the bottom of a hold with other items overstowed. They
may not be corrected there. Repair must not be considered elsewhere on the ship without the approval of the
captain of the port. Replacing shipping bands, loose covers, nose plugs, or strapping is not considered repairing.
