Fire resistance is vital for materials and structures. In today's construction or transportation industries, it takes top priority. It refers to the ability of a material to stay intact under heat, and no significant deformation or loss in strength if it is in flames. This property is essential to ensure occupant safety, protect property and meet building codes. Fire resistance is measured in hours, which signifies the length of time that a material can hold back a fire and prevent it from spreading. Materials with high fire protection ratings such as concrete and steel are often used in the building structure to reduce damage and allow occupants longer time for escape or fire fighting efforts. It is further stressed how important fire resistance is because depending on one's building fire resistance levels, insurance premiums may be lower.
