Intermodal Dry Cargo CNTR/CSC Reinspection Certifier Practice Test

The door sill serves a critical function in the structural integrity and security of a container. It is designed to secure the bottom door cams, which are essential components that lock the doors in place when the container is sealed. By performing this role, the door sill not only helps ensure that the doors do not accidentally open during transport but also reinforces the overall stability of the container's structure. This is particularly important as it protects the cargo inside and prevents potential loss or damage during transit. The door sill must be robust enough to handle the stresses associated with loading and unloading as well as transport over varying terrains. This aspect underscores its importance beyond mere aesthetic value or air circulation, making it a fundamental part of both the container's functionality and safety.
