ABSTRACT
Materials excavated from the Linde site when designated for off-site shipments are placed in intermodal containers (IMCs) and shipped by rail to a disposal facility. Most of the containers used at the Linde project are described as hard-lid containers. The hard lids are constructed of aluminum and are attached to the container by a set of rails, rollers and tie down mechanisms. The rails and rollers are designed similar to a drawer slide in a cabinet and allow for movement of the lid to the fully opened position within the designed limits.
Linde has shipped over 15,000 intermodal containers over an 8 year period without any mechanical problems that would be considered a safety issue. During the past 2 years of excavation, failure of the rail stops to function properly was experienced on a number of containers, enabling the lid to become dislodged and roll off one side of the container to the ground.
A solution providing for the continued safe use of hard-lid containers was found. New procedures were implemented by the Shaw project team with the addition of a lanyard and quick latch mechanism (designed and fabricated at the Linde Site) to keep the IMC lid from dislodging from the lid rail.
