What material should not be used in construction near flames?

Combustible or flammable materials should never be used in construction near flames because they can ignite easily and pose a significant fire hazard. When exposed to heat, flames, or sparks, these materials can catch fire quickly, potentially leading to uncontrolled fires that can spread rapidly and endanger lives as well as property.

In contrast, non-combustible materials, such as certain metals and concrete, are designed to withstand heat without igniting. Wooden structures can pose risks but are sometimes treated to resist fire. Cement-based products, similarly, do not ignite and are often used in fire-resistant construction. Hence, using combustible or flammable materials in areas where flames are present is extremely unsafe and should be avoided.
