As others have said.
Fire ratings are not to be relied upon. Nost safes use gypsum (sheetrock). When it gets hot, it undergoes a chemical transformation to release steam.
Concrete is a slightly better insulator, but not by much.
Keeping your safe against an outside wall will help keep temperatures down.
Never store powder or ammo in a safe. That is a bomb waiting to happen.
