DESCRIPTION:
BRIEF SUMMARY
The invention relates to a transport device for hazardous goods receptacles, with an ISO container receiving the hazardous goods receptacles and means for securing the loads of the hazardous goods receptacles within the container, and to a method for securing the loads of hazardous goods receptacles in ISO containers for transport.
U.S. Pat. No. 3,375,919 discloses a transport device for yarn spools in a package. The transport device comprises the features of the preamble of claim 1. In particular, the transport device comprises a first receiving surface which fills the bottom surface of the package as a single part and is shaped such that a plurality of yarn spools can be fitted in a regular pattern and with a precise fit onto the first receiving surface. Onto the yarn spools a second, correspondingly shaped integral receiving surface is placed in reverse orientation, which second receiving surface engages an upper portion of the yarn spools and which completely fills an intermediate suface of the package. Onto the intermediate surface a further receiving surface is placed onto which a second layer of yarn spools is placed, the upper portions of the second layer of yarn spools being finally engaged by a forth receiving surface, which completely fills the cover surface of the package. Corresponding receiving surfaces consisting of a single part, would, in case of ISO containers, be very difficult to handle and would result in substantial complications when loading and unpacking the containers.
Publication WO 85/01714 describes a method for accommodating barrels of a certain size into an ISO container. For accommodating barrels of 55 US gallons size in an ISO-container it is proposed that the scarf joints at the base and at the lid of the barrel are pressed inwardly so that the outer diameter of the scarf joints is reduced and adapted to the largest outer diameter of the barrel wall. Furthermore, the reinforcing mouldings on the outer circumference of the barrel are changed so that in the small side of the container four barrels can be accommodated side by side, and that along the length of the container 10 rows of barrels can be arranged. Such a dense package of barrels in containers is, for hazardous goods recepticals, not in compliance with safety regulations since, with the barrels abutting each other, upon acceleration of the container the inertial forces of all barrels in a row act on the container wall without any dampening which can result in damaging of the container walls during the prescribed acceleration test.
The invention relates in particular to the transport of radioactive wastes which are stored in hazardous goods receptacles such as say steel drums which are adapted for transport in ISO containers. Special safety provisions, such as are set out in the Law relating to the Conveyance of Hazardous Goods and the Hazardous Goods Exemption Order issued on the basis of the latter, apply to such materials. Listed in the Hazardous Goods Exemption Order of 23.6.1993 is Exemption no. 49, which sets out allowability conditions for ISO containers which are to be used for the transport of LSA and SCO materials. Inter alia, it must be demonstrated that the containers and the lashing of the cargo additionally withstand increased load stresses relative to the ISO standard. According to Exemption no. 49 of the Inland Waterways, Railways and Roads Hazardous Goods Order, certain radioactive substances may be transported in containers only if the latter including the load-securing devices can, at the maximum permissible total mass of the cargo and the maximum permissible mass of the individual items to be lashed, absorb the forces at the following accelerations:
A safety coefficient of 1.5 must be demonstrated.
Previously, hazardous goods receptacles with radioactive contents, steel drums typically being used, were lashed with stretch straps in order to secure the load in the containers. The stretch straps were laid running round several drums and secured in the side walls of the container. This type of load s
