What is the minimum length for a string used in container inspections?

The minimum length for a string used in container inspections is 40 feet. This length is essential to adequately measure and assess various aspects of the container, including its dimensions and structural integrity. A string that is too short would limit the inspector's ability to perform thorough checks, particularly in relation to the container's length and any potential deformations or damages that may occur. The established minimum of 40 feet ensures that inspectors can effectively complete their assessments without limitations, promoting safety and compliance with international standards for intermodal transport.
