Fire resistance refers to the ability of a material or structure to withstand fire or to prevent the spread of flames and heat. This property is crucial in building design, as it helps protect lives and property during a fire. Materials like concrete, steel, and certain types of insulation are often used for their fire-resistant qualities, which can slow down or stop the progression of fire. Building codes often specify fire resistance ratings for different materials and assemblies, indicating how long they can withstand fire exposure. These ratings are determined through standardized tests and are essential for ensuring safety in structures like homes, commercial buildings, and industrial facilities. Proper fire resistance can significantly reduce the risk of fire-related injuries and damage.
