3.5. Fire Resistance

Try these first

1. 1.

   What happens to timber when it is exposed to high temperatures?

   Hint

   Think about what protecting something from heat means.

2. 2.

   True or False: Larger timber sections have better fire resistance.

   Hint

   Consider how thicker layers can protect more effectively.

3. 3.

   What does charring do to timber when exposed to fire?

   • Enhances heat transfer
   • Insulates the wood
   • Makes the wood lighter

   Hint

   Consider how covering something helps.

4. 4.

   True or False: All timber has the same fire resistance capabilities.

   • True
   • False

   Hint

   Reflect on different types of wood you know.

5. 5.

   Design a timber structure incorporating principles of fire resistance. Explain your choices regarding timber size and treatment.

   Hint

   Think about how different sizes and treatments affect charring.

6. 6.

   Analyze a historical case of fire in a timber building. How did the fire resistance of the timber influence the safety outcomes?

   Hint

   Link your analysis to the concepts of fire resistance and safety in timber structures.
