Is Class A fire rating 1 hour?
A “one-hour” fire rating is given to an assembly consisting of various building materials that can resist the exposure of a standardized fire exposure for one hour.

What is a fire rated safe?
Fire ratings are evaluated by testing to see if safes withstand varying furnace heat for specific amounts of time.
