Why I Considered a First Alert Fireproof Safe

When I started looking for a fireproof safe, my main goal was to protect important documents, cash, and small valuables from unexpected emergencies.

What I Looked for Before Buying

Before I made my decision, I focused on a few key things:

  • Fire protection rating — I wanted to know how long the safe could withstand high heat.
  • Water resistance — I preferred extra protection in case of sprinklers or minor flooding.
  • Size and capacity — I needed enough room for documents, passports, jewelry, and backup drives.
  • Locking mechanism — I checked whether it had a key lock, combination lock, or digital keypad.
  • Portability — I thought about whether I wanted a small safe I could move or a heavier one for home storage.
