Which material can ignite as secondary fires?

Explanation:
Secondary fires happen when heat, flames, or embers from the main fire reach another nearby material and cause it to ignite. Wood is a combustible material that readily catches fire when exposed to enough heat or when embers settle on it, making it the typical source of secondary fires. Water isn’t a fuel and works to absorb heat and extinguish flames; steel and glass aren’t combustible and don’t ignite, though extreme heat can damage them rather than start a fire. So the material most capable of igniting as a secondary fire is wood.
