What is a common purpose of heat vents in construction?

• A. To install wiring safely.
• B. To release accumulated heat and smoke.
• C. To detect fire hazards.
• D. To prevent backdraft.

Answer: (B)

Heat vents play a crucial role in ensuring safety in buildings by allowing accumulated heat and smoke to escape. This function is particularly important in situations where a fire might occur, as it helps to prevent the buildup of dangerous smoke and heat that can lead to fire spread or excessive heat exposure to structural elements. By providing a pathway for heat and smoke to exit, heat vents contribute to maintaining safer air quality within the structure, thereby improving conditions for occupants and firefighters during emergencies. Proper venting can significantly reduce the risk of flashover, increase visibility, and enhance the efficacy of fire suppression efforts.
