Fireproof safes are designed to safeguard valuable possessions in case of fire, in addition to theft. They can be classified into different categories. For instance, a class-A fire-resistant safe could protect paper at 2,000 degrees for four hours. Assume your class-A fire safe eventually melted after a fire took place for three hours at 2,000 degrees, and you lost all your valuables. Describe the quality of the safe in terms of both value and conformance.
