What is a hazard during vertical ventilation on clay tile roofs?

• A. Debris falling danger
• B. Thermal expansion
• C. Glass breakage
• D. No hazard

Answer: (A)

Vertical ventilation on a clay tile roof primarily creates the danger of debris falling. Clay tiles are brittle and can crack or loosen when lifted or removed to create an opening. Those broken or detached pieces can drop to the ground or onto people below, making falling debris the main hazard in this scenario. Other issues like thermal expansion or glass breakage aren’t the central risk here, and saying there’s no hazard would overlook the real danger of falling material. Plan for debris containment, keep a spotter below, and use fall protection to manage this risk.
