An unapproved modification that penetrates a fire wall can compromise which?

Fire barriers are designed to maintain compartmentation by resisting fire for a specified period. When an unapproved modification cuts through a fire wall, that continuity is broken, creating a path for heat, smoke, and flames to spread between areas. The fire-resistance rating of the barrier is compromised, which defeats the purpose of the wall in limiting fire spread. Proper fire-stopping or approved detailing is required for any penetrations to preserve the barrier’s rated integrity. The other options don’t address the building’s ability to contain fire within its designated compartments.
