A structurally serviceable freight container loaded with Class 1 explosive materials cannot have a major defect in its strength components. Which of the following would make a container non-serviceable?

Correct Answer: Option A — dents or bends in the structural members greater than 0.75" in depth regardless of length

In accordance with 49 CFR and hazardous materials handling standards, structural freight containers intended for Class 1 explosives must remain free of major defects. Dents or bends exceeding 0.75 inches in depth on primary structural members compromise container integrity, rendering it non-serviceable.
