The international convention for safe containers has 2 goals :
First is to maintain a high level safety of human life in the transport and handling of containers by providing general acceptable test procedure and related strength requirements.
Second is to facilitate the international transport of containers by providing uniform international safety regulations equally applicable to all modes of surface transport.
overall CSC insures containers are built safely, inspected regularly with the idea of keeping workers as safe as possible.
Once a container meets all CSC and ISO standards it is assigned a CSC number. The number appears on a safety approved plate or CSC plate based on the CSC certificate this must be attached to the container.
The plate indicates that the container has passed certain test or re-tests and has met certain minimum standards on weight capacity and resistance to force.
