What characterizes Type 2 construction?

Type 2 construction is characterized by the use of non-combustible materials that have defined fire resistance ratings. This type of construction typically incorporates materials such as concrete and steel, which do not add to the fire load, therefore providing a certain level of structural integrity during a fire incident. The fire resistance ratings are crucial, as they determine how long the structural elements can withstand fire exposure before failing.

This construction type offers a balance between safety and cost, making it common in commercial buildings. The use of non-combustible materials not only helps to prevent the spread of fire but also protects the structural components for a longer time, allowing time for evacuation and firefighting efforts.

Other options may reference qualities that are not applicable to Type 2 construction. For instance, high flammability or the use of entirely combustible materials would contradict the inherent design of this construction type, which aims to mitigate fire risk.
