Fire safety

Fire safety is a new domain emerged in the early 90s to enable the design of buildings, structures, and infrastructure against destruction through fire. It also includes the provisions of building codes. This field is mostly associated with the design and efficient planning of a building, to reduce the destruction caused by fire. The branch of engineering that deals with it for the safety of the buildings from destruction of fire, is known as fire safety engineering.
