What is the fire-resistance rating required for a two-hour fire wall?

30 minutes
1 hour
1.5 hours
2 hours

The correct answer is: 2 hours

A two-hour fire wall is required to have a fire-resistance rating of two hours, meaning that it must be able to withstand fire exposure for that duration without failing. This rating is established by testing the materials and assembly of the wall according to specific standards, ensuring that it effectively limits the spread of fire and maintains structural integrity during that time. The other options reflect ratings that are less than two hours and do not meet the criteria for a two-hour fire wall. Fire-resistance ratings are determined by rigorous testing procedures, and each value signifies the minimum duration that a fire barrier can function effectively in protecting life and property from fire hazards.
