There are 5 ways that a metal container can breach. What is not considered to be a breach?

• A. Rust
• B. Puncture
• C. Crack
• D. Rupture

Answer: (A)

A breach means a direct failure of the container’s wall that allows contents to escape. Puncture, crack, and rupture are concrete failures of the metal wall—they create a hole, a fracture that can propagate, or a complete break, respectively. Rust, however, is corrosion—a slow, chemical wear that weakens metal over time. By itself, rust doesn’t automatically produce a hole or leak; it’s a degradation process that may lead to a breach later, but it isn’t a breach on its own. So rust is not considered a breach.
