Can you repeat the '5 Cut' cutting sequence?

• A. Yes. Will result in Double and Triple Panel Louvers.
• B. No. It would exceed the sequence limits.
• C. Not recommended under any circumstance.
• D. Only with supervision.

Answer: (C)

In vertical ventilation, you create controlled openings that align with the roof structure and fire conditions to vent heat and smoke safely. Trying to repeat a five-cut sequence pushes beyond standard, approved patterns and can produce an opening size or configuration that you can’t reliably predict or control. That increases the risk of structural compromise, backdraft or rapid fire spread, and makes it harder to manage the ventilation path from the crew on the roof and below. Because safety and predictability come first, there’s no circumstance in typical OCFA practice where repeating a five-cut sequence is advised. Following approved sequences keeps openings within known limits and supports safer, more effective ventilation.
