10-5. Cargo Stowage
a. Preload Operations. The LASH lighter should be considered a small ship, and the principles that govern the
loading of any oceangoing vessel with military explosives must be followed. Preload inspections, therefore, are similar to
those outlined in paragraph 3-2, where applicable. In addition, the following special points should be checked prior to the
commencement of cargo-loading operations.
(1) On lighters equipped with removable hatch pontoons, only as many covers need be removed as are
necessary to load the barge safely. Leaving the remaining covers in place reduces start-up and cover-up delays in
addition to providing greater protection from weather conditions. Also, hatch covers left in place make an acceptable
location for the precutting or assembly of dunnage structures. Hatch covers should be removed using a four-leg sling at
least 10 feet in length. Covers should always be lifted vertically since dragging them along a hatch will damage the
waterproof gasket on the underside. Covers should be stacked on a flat surface to prevent distortion and additional
gasket damage. Lighters arriving with damaged or missing gaskets should be reported to the shipping line, since this will
result in the lighter losing its weatherproof seal.
