Why is breaching interior walls not a preferred escape method?

• A. It damages the structure
• B. It requires strength, depletes air supply, and creates an additional flow path
• C. It speeds up escape
• D. It is a standard escape method

Answer: (B)

Breaching interior walls is avoided because it disrupts the controlled airflow and adds hazard instead of clarity. Opening up a wall creates an additional path for air, heat, and smoke to move through, which can feed the fire and push dangerous gases into areas you’re trying to leave or already occupy. That means you lose precious breathable air faster, and the situation in the building can deteriorate quickly as the fire and smoke spread to new spaces. It also requires physical effort and time, which can slow you down at a moment when rapid, planned movement is critical. For these reasons, breaking into interior walls does not reliably improve escape and can worsen exposure and safety conditions.
