Which desmoking kit item covers irregular openings to limit smoke spread during desmoking operations?

• A. Smoke blankets
• B. Fire curtains
• C. Duct caps
• D. Smoke socks

Answer: (A)

The key idea is using a flexible barrier that can conform to non-uniform openings to stop smoke from moving between spaces during desmoking. Smoke blankets are designed for that purpose: they’re large, heat-resistant fabric sheets that you can lay over irregular openings—vents, ducts, hatches, gaps around doors—and secure in place. Because they’re soft and adaptable, they seal around jagged edges and uneven shapes, forming a barrier that reduces airflow and slows or stops smoke spread into adjacent compartments. Fire curtains can seal doorways, but they work best on straightforward openings and require tracks or a clear mounting area, making them less versatile for irregular openings. Duct caps are intended for ends of ducts and don’t address general irregular openings. Smoke socks are handy for smaller gaps around pipes and penetrations, but they’re not as effective for covering larger or uneven areas. So, for irregular openings, smoke blankets offer the most adaptable, rapid, and effective solution to limit smoke spread.
