Regulation 42

Every package shall be so designed in relation to its mass, volume and shape that it can be easily and safely handled and transported and can be properly secured in or on the conveyance during transport.

The design shall be such that any lifting attachments on the package will not fail when used in the intended manner and that, if the attachments should fail, the ability of the package to meet other requirements of these Regulations would not be impaired. Assessment shall take account of appropriate safety factors to cover snatch lifting.

Attachments and any other features on the outer surface of the package which could be used to lift it shall be designed to support its mass in accordance with the requirements of paragraph (2) or shall be removable or otherwise rendered incapable of being used during transport.

As far as practicable, the packaging shall be so designed and finished that the external surfaces are free from protruding features and can be easily decontaminated.

As far as practicable, the outer layer of the package shall be so designed as to prevent the collection and the retention of water.

Any features added to the package at the time of transport which are not part of the package shall not reduce its safety.

The package shall be capable of withstanding the effects of any acceleration, vibration or vibration resonance which may arise under conditions likely to be encountered in routine transport without any deterioration in the effectiveness of the closing devices on the various receptacles or in the integrity of the package as a whole. In particular, nuts, bolts and other securing devices shall be so designed as to prevent them from becoming loose or being released unintentionally after repeated use.

The materials of the packaging and any components or structures shall be physically and chemically compatible with each other and with the radioactive contents, having regard to their behaviour under irradiation.

All valves through which the radioactive contents could otherwise escape shall be protected against unauthorised operation.

The design of the package shall take into account ambient temperatures and pressures that are likely to be encountered in routine conditions of transport.

For radioactive material having other dangerous properties, the package design shall take into account those properties.
