Multiple Choice

Which modification is unapproved and can create hazards?

Fire-rated barriers are built to keep fire and smoke contained in a compartment. Any modification that creates a new opening through a fire wall can bypass that protection and allow fire, heat, and toxic gases to spread more quickly. That’s why penetrating fire walls is considered an unapproved modification unless it’s done with an approved firestop system that restores the wall’s listed fire-resistance rating and is installed per the listed design. Without proper firestop, a penetration becomes a highway for fire spread and poses serious life-safety hazards. Other common modifications listed may be part of normal building work when done to code and with proper approvals, such as removing carpet (often routine maintenance), converting basements into living spaces (requires permits and adherence to egress, ventilation, and fire safety requirements), and installing smoke detectors in appropriate locations (a safety measure, though placement should follow code guidelines to avoid nuisances).
